Started off by taking a wheel off of one of my rollerblades. I wanted the bearings. Found a bit of tubing that had exactly the right diameter.
did some cutting
and some drilling
It took a long time. It's just too cold outside, so I had to go in and warm back up again a couple of times. I'll have to make some steps on the lathe and the other side, but I'm pretty happy with the look so far.
