It's time to fine-tune the hubs I made the other day so I decided to make a fixture to speed-up the process. Here's a piece of 1045 with a taper on it to hold the hubs in the lathe for final dimensioning after they've been heat treated. Only on rare occasions do I bring out the tool post grinder but today, I decided to do a pre-test to see if it would work on a taper. It's got some lines but nothing terrible. I suspect it won't happen once the material is a little harder. Raw metal doesn't grind too well.
Anyhow, the fixture has a few more features to be done such as a threaded area to hold the locking collars. I'll mount all the hub pieces on the same fixture and clean-up everything in one shot. Here, I was just doing a little clean-up of the shoulders. The taper is 2 thou oversized which I'll re-grind after part is heat treated.
