As a referred to, there was a sizeable gap between the barrel and the stock. So, I bedded the entire length with Accraglas. I'm sure that the purists reading this have just left the thread in disgust. But, it filled that gap nicely and now it's strong as can be.
When I cut in the barrel tennons my dovetails looked sloppy as anything. So, I bought a jig for cutting in the sights. The cuts look perfectly angled/squared/etc... But, they were way too deep. Next tile I'll be using a piece of leather between the barrel and the inside top of the jig to make them shallower. The rear sight just wouldn't fit. So, I filled a little more off. Still not fitting, So to file again. Boom, slid right through. As in all the way through. Plus, there was a visible gap between the bottom of the rear sight and the barrel. So, I used a small piece of sheet brass and wrapped it around the base of the dove tail. That took some heavt handed blows on the drift punch to get it in. But, now it's solid.
Below are the parts that I made myself. The sight is an old silver quarter.
