Ted, thanks for posting your progress. It is helpful to folks who have not tried this. One thing about the sight....it does do not need to be set flush with the top of the barrel. I have one of the dovetail jigs too.....never have used it. I just do mine "free-hand". My method is to use a small square and scribe a couple of lines on the barrel a bit narrower than I think I need. Then (carefully) make several shallow hacksaw cuts between the lines. Next, file away the material between the lines so the bottom is smooth. Once that is done I use a file with a "safe" side to do the undercutting. I make my own files for this, but they are probably available. I usually make the depth of the cut about half the thickness of the sight base. Once you are close, try tapping the sight base in, right to left. Proceed slowly from this point on. You want the base very snug in the dovetail. I will say that an octagon barrel is easier than a round barrel! Sorry, I didn't mean to hijack your thread.
