"I might have to get the front edge of the butt socket filled to as the fore wood has a 1/2 Mil gap , my nice piece of wood was machined too short ! ! "

I don't know if that's the best way to go about it mate , I'd be looking at making a sheet steel spacer and attaching it to the rear of the forestock . If you just raise the edge of the buttsocket your going to have uneven bearing which is not good for accuracy, and your timber is going to split.
