Drill sheet for RXS300 ?
« on: March 09, 2007, 01:26:42 AM »
Need to know if the drill sheet that came with this ball is correct. I went to Ebonites web site and they do not list this ball in the drill sheet section. My concern is that the enclosed drill sheet is their "symmetric core dynamic layouts". The actual ball has a mass bias mark. This is not mentioned or shown in the layouts. I know this is a low mass bias rated ball, but if this sheet is correct, then shouldn't it still show the MB ? Also shouldn't they include the RXS300 on their list of balls that use this sheet on their website if it is the same?

The guy picked out a label lev layout that would put the MB on the track side of the thumb. Of course it doesn't show a MB on the layout. I am thinking more the pin up and at 5 to PAP and the cg (and MB) swung right. He is slower ball speed ,decent revs...wants the ball to get down the lane, but not be too sharp off the break, but strong and continuous off the break.  Thanks guys, Al

DO NOT put the mb in or near the track unless the backends are screaming where he bowls or he will never kick out the 10 pin. I think your idea of pin up 5" off axis and mb out is correct, maybe something with mb 3-4" from midline.

Yeah, I do not like label drills even on true symmetrics. Sure is scary if they include the wrong drill sheet with these balls.

Got a reply from Jeff Ussery...He said to use the same layout sheet for the Total NV or Angular Ones, not the symmetric layouts. Al

Well, just keep in mind that the mass bias differential of the ball is only .009".  This is much much less than a One series or Total NV Ebonite ball.  I prefer using the asymmetric sheets simply because they're more detailed for you as a customer.  But you would have been able to use the sheet included without issue.

Jeff, I greatly respect your opinions, but I drilled up a SR300 with pin over ring (5") and MB in track (do not drill) and ended up with such a mild reaction that the ball does not carry unless the backends are screaming. I have average speed and slightly above average revs. I understand what you are saying about the .009 MB but it must have some effect.  Have you ever drilled one like this and what were the results? Thanks, Joe

I haven't.  I only drilled the one RXS300 you can find on my website.  You're ball reaction with a very mild backend is what I would have expected given your ball layout.  Layouts like the one you used tend to provide mild and smooth backend motions in most equipment; asymmetric and symmetric.
