I just bought a Weigand Combat scope mount for a Ruger Redhawk. I need to drill and tap two screw holes in the top strap above the cylinder to hold the mount. I have the proper drill and tap.
Should the holes go all the way through the top strap or should they be stopped at a certain depth? Part of the instructions say "Trim the screws flush with the inside of the cylinder window". I assume that this means that the holes go completely through the top strap and then I grind the bottom of the screw if necessary so that it doesn't interfere with the cylinder.
Will two holes spaced about 3/8" apart (lenghwise, not side to side on the strap) weaken the top strap to where I should be concerned at all? The third screw goes in the existing rear site. The mount is desinged for a Redhawk.
My plan is to make sure the drill press table is perpendicular to the drill bit, mount the pistol (padded) in a drill press vise, square the top strap to the drill bit, centerpunch the holes, and drill away. I would guess that I want a fairly slow spindle speed. The pistol is stainless. Any coments or suggestions?
