Mark,

Thanks for that, but if you orignally drill the bore at exactly the same 
as the shank, then why the need to re-drill with a bigger drill bit? why 
not start off with it? How much "wiggle room" do you like to see? Just 
curious.

Best,
Paul

Hi Paul,

I guess you don't recognize me, but I am head of the WNG technical.  We 
have install at least 20 Masons with the Composite Actions at the factory 
and 70 percent have the Gel CA and we found that the No.10 drill size is 
best to give the work time before setup of the glue and the viscosity of 
the glue takes up the gap.  The tighter the fit the shorter the work time 
and that is why some techs have complained about the short work time.

Mark
