pwf has recently serviced the larger lathe at the hackerspace: he adjusted some bearings and replaced a few gaskets. 

A few days ago he used the lathe to adjust the diameter of stage riser parts made of ABS plastic and fiberglass. First, the desired diameter is set on the lathe. After machining, he uses a metal file to remove burr from the part, then switches the lathe to reverse mode in order to take the finished part off.

A couple of finished parts.
