I'll order another sleeve and do a build along sometime soon. The short version is that the sleeve has two brass inserts and I took them both out, carefully fitted them to the ends of the billets. I drew center lines on the billets and did trial fitting into the handle as I worked on fitting the brass pieces to check for alignment. Tried to line up the center lines and induce a tiny amount of backset ~ 1/4". Using billets gives you a little "play" if you fit the take down handle and then do the layout. I also put the finished assembly on a caul after the floor tiller stage to even the backset, move the tips slightly and take out some propeller. It would be almost impossible to do a retro fit on an existing bow.
