Not sure this really qualifies as "gunsmithing" but it was fun. I wanted a tailess grip safety on my Colt Ghost. I found a Wilson's drop in beavertail for a Gov. 1911. This meant the tail would already be to long for my Commander 1911, so a good way to start. I ground the tail off with my grinder, then rough sanded, then fine sanded and polished best I could with what I have.
