I mentioned this in "What gun are you working on" but wanted to give it its own thread. I bought a Remington model 6 bare receiver a while back. I made all the screws (single pointed them on my lathe), made a tap to thread the take-down screw hole, made all the flat springs, milled the barrel shank to fit the receiver, drilled the hole for the extractor shaft, milled the extractor relief, made the extractor, cut the new chamber, turned the barrel because it was not concentric with the bore at the muzzle, draw filed and polished the barrel (from a Remington model 514), recrowned the muzzle, cold blued the barrel and the receiver, made a buttstock and forearm. Also made the thumb piece, which I made in the shape of a trailer hitch ball. I saw one example of the type. It thumbs up and down very easily and I like it better than the knurled cylinder usually seen. Blue on the barrel is the best I have ever gotten with cold blue. I am still working on the steel buttplate and have to add sights. I ran out of good walnut when making the buttstock, so will keep my eye open for a decent piece (cheap, but not a gift). The falling block locks up tight with good spring pressure. Trigger pull is pretty good, though of course not like an adjustable.
