Caution! Perpendicular 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.

Help please! How do i determine if a line is parallel or perpendicular with points given on a graph?
I need to know how to figure this out i have forgotten all that i have learned.
EX: (1,2)(3,4) and (3,4)(5,3) are they parallel perpendicular or neither?
Please help ASAP
they're not parallel, the way you find it out is by finding the slope with the equation y2-y1 over x2-x1
all points are given (x,y) and when you have 2 of them ex) (x,y) (x,y) it translates (x1,y1) (x2,y2). So the slope of (1,2) and (3,4) would be 4-2 / 3-1 which is 2/2 (the slope) which is reduced to 1/1. you do the same thing with (3,4) and (5,3) to get -1/-2(the slope). if the slopes are the same the lines are parallel
