So I couldn’t stand the thought of leaving this botched up job laying around the shop while I worked on other projects. It was 113F here in the desert yesterday so I was only going to get a little shop time in anyway. I used bubinga for the cup and truthfully, I think it looks awful. I thought it would darken more with some oil but I was wrong. I did come up with a clever way to turn the cup and guarantee that it would be centered and aligned on all axes though. After drilling the knot hole I had enough wood at the bottom to drill and tap a hole for my threaded mandrel. I turned the cup on the mandrel, added some wood glue and threaded on the base tightly, wiped off the squeeze out with a damp paper towel and got a perfectly aligned brush handle. Too bad the bubinga was a total mismatch. It would probably look better after the padauk darkens (padauk ALWAYS darkens) but I’ll be turning it off and trying again for something that doesn’t look like it was pieced together by Dr Frankenstein...
