Re: RH to LH
I've done it a couple of times and I drill a few holes in the sides of the bolt slot and put a few finish nails in crisscross pattern and slide a piece of screen door material in there for a matrix. I use bedding compound or JB weld that has been allowed to thicken up for a while before applying. After it has hardened, sand down to match the shape of the stock and repaint. Looks good as new and is plenty strong.
