I finished grinding and sanding my parts and some parts were too rough and had voids in them so I put some PC-7 epoxy on it to fill the bad parts and voids and sanded it again. I then sprayed 2K epoxy primer/sealer on it and sanded it yet another time. I then installed the covers and trimmed the gaskets to match. On the threads of the "adjuster nut" I blued it and put a thin coating of "Sharkhide" on it. The stock tube I measured at 1.75" with .080 wall. My new DOM tube is 1.75" with 0.88 wall so I put it in the lathe and opened up the center at the top.so the upper bearing would fit.
