Drilling suggestions
« on: February 09, 2012, 10:23:58 PM »

I am meeting with my driller tomorrow to drill up a new Crossroad and am looking for feedback from any drillers here on BR before I go.      I am looking for a slightly smoother and more controlled drill than my Hy-Road pictured below.  I know I want a longer pin buffer for length (Pin above bridge) but I am not sure about whether to locate the CG in the gripline, slightly positive or strong positive with a weight hole.  

 

Any thoughts from drillers out there?

 

Thanks

MK

My specs:

rev dominate, high track,
axis rotation approx. 45-50 degrees,
axis tilt - approx 15 degrees
PAP 5 1/2> 1/2^

The key would be a longer pin buffer.  If your track isn't too high, go with a 4.5" pin buffer,which should put the pin below your fingers (if not make the buffer longer).  You can try to utilize a weight hole after drilling to manipulate the reaction more, P2 to lower the transition to friction, and P3 to make it a little more angular.  So CG placement should be in a place that will allow for both placements to work.
