Re: Only half the mass of the ball?

The main negative about a full roller is that it has 0 axis tilt and thus depends solely on axis rotation for its hook. A semi roller does have over 50% of its mass on the side of the ball towards the hook direction until it loses all its axis tilt. I suspect that's what the writer was trying to sa...

Re: Only half the mass of the ball?

Statement seems like filler to me I'm curious what "turned in to" means. Seems like the editors of the manual missed this personal verbiage. The "turned in to" part makes me think they were maybe trying to say something different and it got phrased badly. Something Like maybe the full roller doesn'...

Re: Only half the mass of the ball?

Just in case it makes a difference heres the whole paragraph the quote is from. "The term “full roller” refers to how the bowling ball tracks down the lane. A full roller tracks between the finger holes and the thumbhole, over the full 27-inch circumference of the ball. This is the major reason why ...

Only half the mass of the ball?

I was reading in Chapter 7 – Fine Tuning the Physical Game of the bronze cert. manual about a full roller release and read this: "This is the major reason why the full roller is an ineffective delivery in today’s game; only half of the bowling ball’s mass is turned into the pocket , resulting in poo...

Re: Ball speed table--comment please

The problem with measuring speed via stopwatch, is it assumes the ball is only traveling 60 feet. Someone throwing the ball straight at the headpin will show a faster speed, than someone circling the lane, even if they have the same off hand speed. I believe the difference between these two bowlers...

Re: Vacant bowlers - is this idea crazy?

Having a vacancy might not hurt a team, but it doesn't help it either. A vacancy is like a bowler who always shoots average. He doesn't have a bad night, but he doesn't have a good one either. As far as the money goes, all the leagues I've ever seen. At the end off the season, the league deducted an...

Re: What is the (preferred) Drill Sheet Standard

It may be a little cluttered but well organized. What's going on at the bottom left area of the sheet? I'm not sure what that is for. The lower left is where you put your P.A.P. coordinates, as for the Pin-CG-MBP: box I always assumed that was for the layout used. That sheet isn't really meant for ...

Re: Ball speed table--comment please

One thing about the stopwatch vs video method. They are measuring two different things. The stopwatch method gives you basically a average speed for the length of the lane. For the ball traveling from the foul line to the head pin. The Wiki video method is giving you the at release speed. Based on t...

Looks pretty close.

Here's the formula to calculate it yourself.

The Borden Number?

I was reading some old bowling information from back in 2002 and it talked about The Borden Number. Which you could use to compare balls and would give you a estimate of which ball will most likely tend to snap more. Higher numbers more snappy, lower more arcy. The Borden Number Definition: The Bord...

Re: Lane Maintenance Question

I seen something similar here. They started having a lot of out of ranges, so before they ran the lane machine down the lanes. The lane man would spray or squirt something just on the pin decks, then had the lane machine do the lanes. They only did it for a while then they quit it. I figured they ch...

Re: Quick introduction & question (Thickest coverstock???)

Just a thought: I seen around here a couple of bowlers who had a similar problem. They had the whole area of the fingerholes and bridge drilled out and plugged (looked like one big plug), The plug was thicker than the coverstock in that area and was a more durable material. Then had the fingerholes ...

You could try "Smoke and Mirrors" Fit and drill the ball how you would normally if you think that fits correctly. Then before you set the ball up there for her to try. Wipe all the lines off, then draw a new grip center line that goes down beside the thumb hole (not through the center of the thumb h...

I believe the minus 31 formula just show's the exit point for the oil pattern. Not the actual break point.
