Bat Shaving: People will Drill Out Material from your Bat Instead of a Lathe
Bat shaving is a bat modification that decreases the thickness of a bat’s inner barrel. The end cap is removed and a digital precision lathe “shaves” the inside of the barrel. The decrease of alloy or composite material allows the barrel to flex more at the point of impact, which translates to greater batted ball speed. The greater ball speed can add 40-50 feet with shaving alone, add bat rolling prior to shaving and that number goes up even higher.
There are many people who open up a bat and shave the inside with a drill hone (or drum sander). A hone will create “hot spots” and “dead spots” through out the shaved barrel. A hot spot is where the spot is shaved too much and the barrel will flex more. This sounds good because we want more flex for more distance, right? Not exactly, the hot spot will cause a weak spot on the barrel and increase the chance of cracking significantly. There are predetermined widths for bat shaving, which test the limits of the bat as far as strength and durability. Sanding past these limits will cause your bat to break prematurely. The dead spots are just the opposite of hot spots; they cause the bat to flex less, which causes a decrease in distance. A bat straight from the factory will often have inconsistencies of 5-10 thousands of an inch along the barrel already. The precision lathing of your bat will actually create the most accurate wall available. A constant wall allows the bat to have the same flex around the bat for increased distance and better durability (remember, a shaved bat is less durable). The main point is that sanding the inside of a barrel will never be consistent or precise, only a lathe can do that. Most people who shave on EBay (and even some on the internet) utilize a drill hone (drum sander); this is why you will see cheap prices on EBay for bat shaving services. A CNC lathe should have a digital read out to lessen the chance of inaccuracies. One pass through the lathe is not as accurate as taking out material in 2-3 passes. It would be like using coarse grit sand paper as opposed to a fine grit sand paper. The fine grit will take longer but it produces a better product. When the bat is taken out of the lathe it will have lost 1-2 ounces of material depending on the manufacturer of the bat (different bats have different specifications). That weight needs to be put back into the bat at the handle and end cap, an extra amount can usually be put into the cap for an end load. If you did not know, all manufacturers create their barrels to weigh the same. They put metal weight into the handle and extra resin into the end cap to weight the bat anywhere from 26 ounces to 30 ounces. After the weight is added back the end cap is put back on using the correct glue, substandard glue could result in the end cap separating and even popping off.
**Caution** Perpendicular Bat Rolling is Not Enough
Only rolling perpendicular had been good enough in the past and was the industry standard in the infancy of rolling bats. That is until BigDawgBatRolling enhanced this older idea of rolling. Bat rolling perpendicular followed by parallel generates Optimal Distance Results.
The physics of the composite bat facilitates this type of rolling to achieve your Optimal Distance Results. Perpendicular rolling breaks resin up in elongated sections along the barrel of the bat. The perpendicular roll flexes the barrel 1 to 1 ½ inches length wise but width wise that number decreases to just ¼ of an inch. A normal bat is 7 inches in circumference; this means to effectively roll a normal softball you would have to perpendicular roll on 28 points. Some would say that parallel rollers were made to speed up the rolling process and this seems to true. I am sure the creator of the first parallel roller did not realize perpendicular rolling took that long for an effective roll but none the less they wanted a quicker roll. This eagerness has propelled the bat rolling industry onto a new path for bat rolling. The technology of the bat rolling machines today do not allow for a systematic 28 point perpendicular roll. Effectively rolling perpendicular only would be a tedious and unworkable task. Along came the parallel roller and the bat rolling process was improved.
You will hear that parallel rollers will put too much stress on the bat. To an extent this is true; with rollers longer than 6 inches you will break up the resin to close to the taper and end cap. The 6 inch roller only covers the sweet spot and does not come too close to the taper or end cap area. The barrel flexes as pressure is increased. The flex at maximum pressure in a parallel roller will extend out 1 to 1 ½ inches past the roller. A 6 inch roller will not damage the end cap or taper area when parallel rolling because the flex created does not extend into those areas. The width flex stays consistent around the entire length of the bat because the roller never leaves the surface of the bat. This will break up resin at every point along the length of the roller plus 1 to 1 ½ inches past the rollers (which are referred to as the sweet spot). The area at the top of the bat has been shaven down to facilitate the end cap placement and is susceptible to breakage while rolling. Also, if the taper area is compromised by breaking up the resin the life of the bat is drastically reduced. The taper area acts as the fulcrum in the mechanics of a swing. This area has to be the strongest part of the entire bat and bat rolling near the taper is a big bat rolling mistake.
I went over the benefits and physics of why to perpendicular roll and then parallel roll your bats. Just remember perpendicular rolling is good but perpendicular followed by parallel is what the industry standard has evolved to.

Bat Rolling Machines: Would the real #1 Please Stand Up?
I did not want to put my bat rolling company’s name to just any brand of bat rolling machines. So I did extensive research on bat rollers, the physics of bat rollers, and actual companies and their reputations. This was about a 5 month process. I was surprised to learn some of the information I obtained. The thing that sticks out the most was that Juiced Inc. was the first to build these bat rolling machines, a process that started in 2003. They are truly the “original bat rollers” as their website suggests. They have registered for a patent on the actual process of bat rolling, which encompasses all aspects of the industry of bat rolling. What did that mean to me? It meant that by choosing juiced Inc. bat rolling machines I would be legally bat rolling when the patent is approved (which is in the final stages). This however was not the only reason I decided to go with juiced Inc., there were several.
When I did my research I also focused on the physics of the bat rolling machines, basically which one was the easiest to use and built to last. I know other bat rollers in my area that roll in parking lots, so I got to see some of these machines first hand. The oddest bat rolling machine I saw was the one where you need to use wrenches to compress the rollers, what a headache. I also saw one that I thought was the 200PCCR that I had been using but it was a XR-400. Everything was exactly like the 200PCCR (I mean exactly) except for the 7 inch (Update- They have now changed their rollers to a 6 inch) roller instead of the 6 inch roller the 200PCCR has. It was kind of like Vanilla Ice and the Ice, Ice, Baby song that stole Queens’ Under Pressure beat; Quoting Vanilla Ice, “It’s doo doo doo doo doodoo doo doo doo and theirs is ding ding ding ding ding da ding ding. Hear that extra beat?” It is still funny, I don’t care who you are. When I talked to Juiced Inc. they said they had tried different size rollers and the 6 inch worked best on the sweetspot. When manufacturers claim the whole barrel is the sweetspot they are bending the truth. What that means is there is less composite material located towards the taper and end cap. The taper area is actually an overlapping of composite creating a joint in which the resin needs to stay intact. If the resin breaks up in this area the bat is susceptible to breaks. The end cap area has a significantly less amount of carbon fiber because an area needs to be lathed out for the end cap. If a roller larger than 6 inches is used it puts undo stress on the end cap area and taper section reducing the life of the bat.
Durability was a big deal with me because I had 2 bat rolling machines break before I got the 200PCCR. I had the bearings wear out after about 200 bats rolled and I had the actual roller separate from the turning mechanism on the other after 300 bats. I was stuck with 2 broken bat rolling machines, neither bat rolling machine person (I dare not call them a company) would fix or replace my bat rolling machine. So then I got the 200PCCR and 1200 bats later the roller had a small wave in it and the roller was starting to drag. I contacted Juiced Inc. and within a week I had new rollers and they did something to fix the drag (They have now upgraded their rollers and bearings, this will be a problem of the past). I was impressed with the guarantee and that I had no problems when I asked to get it fixed. This experience stuck with me and I remembered it while searching for a credible and worthy bat rolling machine company to market on my site.
I talked to a few bat rolling companies before deciding and Juiced Inc. had the most going for them. The patent pending is a huge deal for anyone who buys, sells, or rolls bats. It would make it illegal to sell or roll a bat with any other bat rolling machine. So if you have another companies bat rolling machine, when this patent goes through, you will not be able to advertise or continue rolling legally with that bat rolling machine. As far as Customer service, they are the only company to offer a lifetime guarantee on their machines (A guarantee speaks volumes)! No other company will come close to that. They are that confident in the modification and upgrades to their bat rollers. This spoke volumes when making an educated choice. And about Juiced Incorporated’s vision; after speaking with them they are committed to this business and making top quality bat rolling machines. The others I talked to were flighty and when I asked about a guarantee and they were not ready for that type of commitment.
There are only 5 other companies with a website (I say that because you can purchase a backyard roller from eBay made in Joe’s garage) that sell bat rollers, out of those 5, only 2 sell a parallel rollers. With the new upgrades of new roller material, precision machined rollers, thrust bearings, and radial bearings these bat rolling machines will not be touched on the open market. And to add to that, once the patented goes through this will be the only company on the web selling bat rolling machines.
This was a no brainer as far as my decision to go with Juiced Inc. bat rolling machines. They have a superior quality machine and a commitment towards the future of bat rolling as well as their company’s longevity. The top 3 Bat Rolling companies use Juiced Inc. machines. There are 11 bat rolling companies on the Internet and 9 of those companies use Juiced Inc. bat rolling machines. EBay is no different with 15 of 20 using Juiced Inc. bat rolling machines. With out a doubt, they have created the #1 Bat Rolling Machines on the market. Anyone who is telling you different is selling propaganda and not selling the world’s finest bat rolling machines, you can quote me on that!

Bat Rolling Guide
Bat rolling has been a guessing game for most people who bat roll; what pressure to use, how long to roll, what bats break easily and so on. There are quite a few more issues with bat rolling than just putting pressure A and rolling through B amount of times. People are purchasing bat rolling machines and checking out pressures on customers from EBay and Craig’s List. I can tell this by some of the bad feedback that is given on EBay and forums. There are small amounts on forums, videos and web pages on how to bat roll but no magic guide for rolling. It is odd to say that bat rolling is an art, but it truly is a complicated process. I had a college professor say to our class one time that reading a book, an 1 hour a day, on a specific topic will make you an expert on that subject. I would definitely say this is false for bat rolling, although it is a great start. In my opinion, an hour or two a day of bat rolling will lead to becoming an expert. Practice definitely makes perfect with rolling.
Picture this, there are about 22 people advertising bat rolling services on EBay and out of those only 5 have been bat rolling for more than a year (as far as their time on EBay or as Internet company). In addition, there is no method to know how long someone has been rolling when buying from Craig’s List. If a good ad on EBay or Craig’s List can drag you in to give up your $400 bat then so be it, but my dollars would be better left with the person who has great feedback and has put out the time and cash into maintaining a website. Customer referrals are a great way to go, that is, if you know somebody. Please do this before you get your bat rolled… do some investigating on the person or company rolling your bat. Examine EBay feedback and look on the internet, it does not take a lot of time. What is 20 minutes to make certain your $300-$500 bat will not get broke. Most legitimate bat rolling companies offer a cracked bat guarantee. Some of the widespread things you will find on EBay are: “do not let an amateur roll your bat”, overstated distance results, like saying you will gain “20-60 feet of distance” (20-40 feet of distance has been established, no more). People actually have pictures of bat rolling in their living room as an ad picture. I have seen one guy” blame the manufacturer for breaking a bat, are you kidding me? Same guy wrote that the bat will be compressed at .186 inches; this would break any bat before you went half way to .186 of an inch, ridonkulous. One guy offers “hot” and “super hot”, Email him and see if there is a “super dip dooper hot”. Please do not take offense if you do roll bats just tell the facts and run a bona fide business with no outlandish propaganda. Every bat rolling company will benefit in the reputation of quality bat rolling instead of a few second-rate rollers leaving a bad taste in customers and potential customers’ mouths. In the Marines we used to call the bad seeds the 10% that recruiters shoved through. Unfortunately I see plenty more than 10% as I look on the Internet and on EBay. I am sure the top bat rolling companies will read this article and understand precisely where I am coming from. Those few bat rollers who don’t understand will be waiting to “go to work on” that brand new $300 bat you have.
The 10% I speak of have been doing things to harm the industry and character of bat rolling, which has been aggravating me for long time. Seeing the nonsense around I wondered to myself, what can I do? I did not want to mention anyone by name because that discredits me also. I needed to do something to help. Have you ever heard the statement, “Give a man a fish”? I am sure you have heard that. I figured I could create a base for bat rolling to help those who want it. Share the experience of 3 years of bat rolling, hopefully that can make a difference.

Is Bat Rolling Illegal? What does ASA, USSSA, and NSA Say?
It is clear that all associations believe that altering a bat not allowed as spelled out by their rules but let’s clear the air; there is not any law that states a rolled bat is illegal. It would be hard for a prosecutor to prove that a rolled bat is any hotter than a bat broken in by hitting baseballs or softballs repeatedly. There have not been any landmark civil suit cases to date. There has been one court case to date about altering bats but this was a shaved and a painted bat: “Oklahoma City, OK—The Amateur Softball Association (“ASA”) is pleased to report that the U.S. District Court for Western Oklahoma has awarded ASA $100,000 in damages and attorney’s fees totaling approximately $12,000 against the first two defendants in the Association’s ongoing attempts to rid the game of softball of illegal equipment including painting and other techniques used to alter bats”. This was not damages to a person but to the ASA organization and it was three years ago. Association can suspend you if a bat is found to be altered but bat rolling is virtually impossible to detect, without a shadow of doubt. Unlike shaving or end loading a bat the effects of rolling are not easily detectable. A bat would need to be cut long ways and scientifically examined to find a pattern of resin break down consistent with rolling; no association has that type of time or money. I have personally known of bats that were sent to large bat companies for warranty which were rolled and not one was denied a replacement.
I will now go into what each association’s rules are in regards to rolling.
ASA
Rule 3 Equipment
“We have had several questions pertaining to bats and what is legally permissible to do to a bat. One item that appears to keep coming up is the rolling of bats for quicker break in of the fibers. There are those who maintain that rolling of one’s bat is perfectly legal. According to Rule 3 Section 7 NOTE: ‘The characteristics of any approved equipment can not be changed. Examples’. Therefore, according to our rules, rolling of one’s bat is illegal and would make that bat an altered bat according to Rule 1 Altered Bat: When the physical structure of a legal softball bat has been changed”. They specifically mention bat rolling but as I stated earlier there is no way to detect rolling.
USSSA
“Altered Bats – Excessive Pressure Included in the USSSA view of what is an altered or doctored bat are any bats that are subjected to pressure in any manner that exceeds that of striking the bat against an approved ball traveling at game like speeds. Such excess pressure would include, but is not limited to, any compression, rolling, placing in a vice, hitting a stationary object such as a pole, etc”. Again the same type of verbiage
NSA
“An altered bat is considered altered when the physical structure of the legal bat has been changed in any way, or when an illegal or non approved bat has been made up in such a way as to appear to be a legal bat. Examples of altering a bat are, but not limited to the following: Painting a bat, replacing the handle or shaving the handle or barrel or the taper changed in any way. Such as by sandpapering or applying a solvent to the surface such as fingernail polish remover or by any other means. Removing or replacing the plug or changed in any way other than factory repairs. Had the knob removed/ replaced or changed in any way or had anything removed or added to the inside or outside of the bat other than the legal way to tape the bat the specified and appropriate place as described in the NSA Rule Book”. There is nothing specific about rolling but some could see this as a way to say it is illegal.
Bat rolling is a very hot topic among softball associations, players, and bat companies. Associations are trying to level the playing field as best as possible with their resources. Only one bat company has made huge commitments to keeping altered bats off the field of play. Easton has made reveal composite and started stamping there end caps where the cap meets the bat. This, I’m sure, has made a slight dent in altered bat use but without testing bats at the parks with a precise compression tester there is no end to bats going above the mph legal limit. ASA has made such a machine but it is archaic at best. The machine can tell if the bat is over the 98mph limit but it will not tell you by how much. Bats that are broken in by batting practice can be deemed illegal because they are over that limit and with that the owner is at risk being labeled a “cheater”. Bat companies are to blame, for the most part, because there is an unspoken competition as to whose bat can change in batted ball speed the most after being broken in. This would be the bat everyone seeks to obtain and thus sales go up. With all that being said bat rolling is no different than a well broken in bat, so why spend days, weeks, or even months breaking in your bat when you can get it rolled? With such a drastic difference between new and broken in bats, you need to get your bat rolled or spend days breaking it in to level the playing field. If it was increasing distance like shaving does I can see the argument of cheating but we are talking about apples and oranges. Bat rolling simply speeds up the break in process with out any detection.

Can Bat Rolling Be Detected?
Almost everyone who rolls bats will tell you that bat rolling cannot be detected; to an extent this is true. Any bat can be rolled and be undetectable; this statement comes with some exceptions. On about 90% of bats rolling is virtually undetectable, even if a trained bat roller was given the bat for inspection. The other 10% of bats have issues with being undetectable.
When a company says that bat rolling is undetectable they are not lying but they are not telling the whole truth either. As I said earlier all bats can be rolled with no detection. In order to do this the bats will not come even close to being fully broken in. What that means is the pressure put on the bat will be insufficient to break up the resin. I believe some bat rollers are fearful of breaking bats or are inexperienced and do not know how to properly break in a bat. This would be why they bat roll with less pressure. Some composite bats and all aluminum bats will have long flat spots along the entire length of the barrel after bat rolling. With composite bats, this is usually caused by inferior composite material but can also be caused by too much pressure. So the question is what if I have one of these bats that bat rolling will leaves marks? Answer: A knowledgeable bat roller will develop tactics that will work around this problem. One of these tactics is parallel rolling. One cannot effectively roll an aluminum bat with a perpendicular bat rolling machine. Let me say that again “You cannot effectively roll an aluminum bat with a perpendicular roller”. This is where a parallel rolling machine is a necessity. It will effectively roll the bat without leaving flat spots.
I can say the same thing about some composite bats. As I stated in the second paragraph some composite bats are made of inferior material and perpendicular rolling can cause flat spots. Some of these composite bats include: 2009 or above Mikens and Worths, Easton Extended 2008, TPS bats, most youth fastpitch bats, and most youth baseball bats. This is not an entire list but it gives you an idea of some of the potential problems with perpendicular rolling. I mentioned that Mikens and Worths have this problem, this is not to say that they have inferior composite but it definitely happens to these bats. Again this can be avoided with a parallel roller and an experienced bat roller. So if these types of bats are rolled to there full potential in a perpendicular bat roller there will be flat spots. Again, there will be flat spots with perpendicular bat rolling.
Getting back to the original question, can bat rolling be detected? No, as long as you use a parallel roller and an experienced bat roller. I have personally sent 4 bats back to Easton and Miken that have been rolled and received my replacements. You will see bat rollers on Ebay trying to get your business without any real experience. You will see things like “we can roll them ‘Hot’ or ‘Super Hot’”, what in the world is this? You will see claims of 20-60 feet; rolling has only been proven to increase distance by 40 feet. You will see bat rollers blaming bat companies for graphics coming off. Ebay is a crazy mess with inexperienced bat rollers. What to look for: look at ebay feedback, make sure you get it done through a legit bat rolling company, and find a bat roller who does both perpendicular and parallel. This will increase your chances of not getting a detectable bat after bat rolling.

Bat Rolling becomes a must with new MPH Rules Coming
Anyone who has played with an all-composite bat realizes that composite bats are often not as hot “out of the wrapper” as they are after about 500 to 700 hundred hits have been put on to the bat. This is the main reason that “artificial break-in” techniques are applied to a bat, players want to cut down the time required to get their new bat to its top hitting performance. The amount of improvement in performance varies from bat to bat, but all composite bats tend to improve the more they are hit. This is true despite marketing claims that a particular composite bat is “hot right out of the wrapper”. This fact creates a problem for softball associations who are trying to reduce the on going problem of illegally altered bats because it can sometimes be hard to determine whether the increase in performance is due to the bat having been doctored or just due to its natural break-in process. Some of the associations are placing considerable pressure on manufacturers to manufacture bats that do not increase in performance over time. This is almost an impossibility when it comes to composite type bats. And while some of the processes being made for detecting bats which perform higher than the set mph performance standard may not be able to differentiate between an altered bat and a naturally broken-in bat, the associations’ belief is that if a bat bears a certification stamp then it must perform at or below the performance limit represented by that stamp throughout the bat’s entire life. The ASA did allow a plus or minus variance on the bats but that went away with the 2004 ASA standards and so did those bats (Freak, Synergy 2 etc.,). But now it doesn’t matter how the bat increased in mph performance; any increase in mph performance after the manufacturing of the bat it is not allowed.
An example of how serious associations are taking this issue, the ASA recently changed their bat certification policy. When the ASA certifies a bat as passing its 98-mph Batted-Ball Speed standard, that bat is expected to pass the standard for the life of the bat, even after being broken-in. As of October, 2007 all composite bats are now being artificially broken-in using a bat rolling method before they are sent to the Sports Science Laboratory at Washington State University to be mph performance tested for certification. I’m not exactly sure what it means for the future of ASA softball, or for the future of composite bats, but at the end of January, 2008, only one composite bat (including all 2007-2008 composite bat models that had previously been certified “out of the wrapper”) has passed the 98-mph ASA certification test after being broken in by bat rolling. The ASA is rumored to be changing its “out of the wrapper” batted ball speed to 93mph, this is shaking up the bat industry and some are debating whether to make ASA bats at all. I would expect to see some changes in the design of composite bats in 2010 in accordance with the ASA policy change. All bats will probably be made at the 93 mph limit to start because after bat rolling the bat will be right around 98mph.

Bat Rolling and 2010 ASA Standards
There has been a lot of speculation and buzz around the softball community concerning the new 2010 ASA bat mph standards. 2004 has the ASA standard at 98mph and bat companies stayed below this standard and as the bats were broken in or put through a rolling machine the mph increased. Late 2007 the ASA came out with a bat compression testing machine that was used at Worlds to make sure bats were below the 98mph standard. These machines are expensive and have not made it around the ASA softball community to police bats as hoped. The machine shows a light if the bat is in fact over the 98 mph limit not the actual mph reading. These machines have had there problems with maintenance also. Softball parks were just not ready to shell out the $1000 for a bat tester which has no real way of gauging the mph.
The ASA will not comment on their plans for the 2010 season but they had to let bat companies know what is coming. Because of this fact some representatives have this information; I had talked to 4 representatives from 3 different companies and all four said they were aware of a 93 mph limit for bat manufactures in regards to new bats in the future. I could not get specifics because they had none but they knew something was coming and everyone of them quoted 93 mph. One did say that the pre 93 mph bats will be phased out like the Miken Freak, Easton Synergy 2, and Mizuno Orange Crush were in 2004. These bats were put on a 2 year time limit and then they were illegal for ASA play. Were does bat rolling come into play with all this? This is the method ASA representatives based their decision on. Basically, how much more mph batted ball speed will a bat gain by rolling it. The 5 mph gap the ASA has (potentially) seems about right because rolling increases distance 20-40 feet which equates to about 2.5 mph to 5 mph (every mph= 8feet of distance). This is great news for and bad news for bat selling companies. If this is true then all the pre 93 mph bats are going to sit there like logs with no one wanting to buy them because of the ensuing changes.
These bats will be the hottest thing on the planet and then when the ASA announces the ensuing banned list they will become useless because of the mph rules in other associations; the bats in these associations hit much farther with a higher mph limit. 5 years of making these bats and all of them will be junk it is hard to think of all the money invested that will be wasted with this new rule. Some people are speculating that ASA is going to go to all aluminum bats; this is not true. You will hear a lot of things out there but the consistent number will be 93. So get ready to be disappointed!

What exactly is Bat Rolling?
Composite bats are made of several layers of carbon fiber, resin, and glue. As a bat comes from the factory the resin and glue between the fibers are rigid and less pliable. When a bat is struck by a baseball or softball the resin and glue start to break, this is what players would call “broken in”, literally. When the resin and glue loosens up the bat becomes more flexible in that area . The same thing is achieved through bat rolling, a bat is compressed through nylon or hard rubbers rollers and the adhesive breaks up leaving the section more flexible. Now as we roll around the circumference of the bat 8-12 times the bat becomes a lot more flexible. This flexibility equates into an improvement in batted ball launch speed and farther distance of launched baseballs or softballs. Reasearch has been performed and found that some bats after being rolled rose up as much as 5mph in mph. You can calculate about 8 feet per mph of hit ball acceleration.
Now, wait a minute isn’t perpendicular bat rolling enough? Sufficient is a perfect adjective because the answer is yes, but if one wants the carbon fibers broken up entirely you would have to make about 8-12 more runs through perpendicularly trusting you roll the bat on the correct area. When the bat is taken through perpendicularly, an assured way to break in the rest of the bat is to roll it between a parallel rolling machine. This breaks up the glue that the perpendicular bat rolling ignored, for a more reliable and flexible bat. The parallel rollers can not be long, although, because there will not be a steady and stable force over the length of the rollers. The rollers really need to be a maximum limit of 6 inches in length; this would cover the entire sweet spot on all bats.
It would appear like breaking up the resin would decrease the longevity of a bat. To a degree this account is correct so you could expend about 24 hours of batting practice breaking in every spot on your bat, trusting you didn’t fail to area or get bat rolling. In the first occurrence one could get about an extra 24 hours of bat life as long as you did not beat the bat in the same area 10 times hence decreasing its life. If you had problems following that I will explain: bat rolling breaks in the entire bat with a few swoops. Breaking in a bat in by taking batting practice causes an inconsistent break in and increases the chances of breaking the bat quicker. The bat continues to have a strong interwoven mesh of carbon fibers throughout all of the bat which is very strong, this is what makes it possible to stay tough and contract when the resin is crushed up.
What are we looking at, the bat rolling method increases the bat’s batted ball speed and has a longer life than a bat broken in the same amount through normal hitting. Sounds good to me but some associations of softball have stated this an illegal conversion. Bat rolling, when done correctly, can not be detected: so what the sanctions do not know can’t kill them.
