How do you drill offset asyms
« on: November 11, 2006, 11:44:01 AM »
I have a friend that got a Track Xception from a closeout deal a while ago.  well this ball has probably the worst pin/cg/MB line I think I have ever seen.  Its a 1 inch pin, and it is literally in a "T" to the mass bias.  basically its like this

P CG


MB

We tried a drill with the MB on left side of thumb and it just did not roll well at all for him.  (fairly low rev, slow ball speed, high track, stroker).
I have heard of layouts where you draw a line 13.5" from the MB through the Pin and then use the spot you end up with as the MB???  Not sure if that would work or not as I'm not exactly a pro on Asyms.  basically if I can do this then I would lay it out something like pin next to ring with the CG kicked towards the Midline and then have the Opposite MB mark around 3-4 inches away from his PAP.  Anyway,  just wondering if this would be a legal drilling and how it would work, the pros, the cons, etc.  I'm hear to learn so go ahead and teach me.

Thanks,
Jeremy

Sounds like he ended up with a ball like this Rule Delta-1...

yeah ball is a lot like that Delta 1 as far as layout.  Didn't think about posting this in the track forum but will do.  Hopefully I get some good hits in there.  Thanks

I would say go ahead and lay it out as you normally would (possibly using a little stronger pin position than normal to help offset the likely required weight hole that's going to be in a flare reducing position).  I would suggest drilling the ring finger extra deep and the thumb as shallow as possible to help out with statics...  Once that's finished, weight it up and drop a weight hole as needed to get the statics back to legal..
