don't think this is the easy part. go slow.... use a drill press and make sure you have it set for 90 degrees.
leave enough under the screw thingy to have strength.
do the frame angle first, then make sure it's tight and fits perfectly. you cannot go back here.
use long set epoly, and mix in some of the sawdust you collected from the grips and use this to fit inside tightly
. coat the metal with car wax. the kind that forms a white film....leave it to dry.
mix the epoxy and put in some dust to get the color and thicken it....put the grips together and use a
clamp to push it tightly. let it set for two days.....when it's dry, you can tap the grip off and you'll have a perfect bed.
I do the same with the hole for the pin. doing this insures it will be a tight grip.
of course, the best way is to polish sand strop the grips to the frame. ok if you have a steel frame. not if you have aluminum...
There should be NO light around the grip. if so...keep sanding until you get that perfect fit.
I've done ivory, wood, presentation walnut, and now Elk antler, and they look great. I really like the elk...
send me a PM with your e mail and I'll send you pictures. (Cant figure out how to do it here) Ken
