Recoil Pad Installation - How to suggestions please

[Pa SxS]

Years ago I bought a 12" disk sander and what I call the "J" style jig that attaches to the sander. Here is a picture of the first recoil pad I made. No comments please about the KickEzz pad, I have the original DHBP to put back on if needed. The challenges were the curved butt and the widow's peak. I tried heating the pad and letting it cool hoping it would prevent a gap when the pad was mounted but I couldn't make it work so I cut a plug out of the center of the pad, installed a screw and put the plug back in. For the widows peak, I mounted the uncut pad, put plenty of release agent around the wood and made a dam around where the widow's peak would be. I also drilled small holes in the pad and inserted small pins. I injected black dyed Accraglass into the void with a syringe body and hoped for the best. After it cured, the pad was put on the jig and finished the normal way. You'd never know the widow's peak wasn't part of the pad originally.
