I'm working on my second set of scales, micarta with a G10 wedge. Some power tools (orbital sander, dremel, jig saw) but mostly by hand. Got the micarta shaped to where I wanterd it but ran into a problem with the wedge. As I understand it, the wedge, at it's widest point should be half of the size of the tang. Then it should taper to x. The question I have is, what is x? Should x (the narrowest point on the wedge) be half again the width of the wedge? That is if the tang is 1/4" then the wedge would be 1/8" at it widest. Should the narrowest part of the wedge be 1/16"?

I thought that the wedge I made had enough taper but once installed, it didn't create enough flex for the tang to pass into the scale without rubbing. It was fairly centered in the opening but no amount of pinching at the rear of the scale created an opening wide enough for the tang. So either the wedge didn't have enough taper or the sanding on the wedge wasn't completely flat.

The white stuff between the wedge and the scale is powder from the sanding so there wasn't a good bond there, certainly part of the problem.

Anybody know if the solvent for CA will melt micarta?
