Paul,

With the original WNG glue, which is a much thinner viscosity, the 4.8mm drill, which is .004" larger that 4.7mm, 
was correct for the sanded shanks.  But since we have changed to the Gel CA glue we needed to change the drill 
size.  Now it is not necessary to sand the shanks for good bond with the Gel CA and this bring the shank to the 
true 4.7mm (.185") size.  So the .193" is not too much "wiggle" room at all, especially with the thicker viscosity Gel CA.

Thanks,

Mark
