I'm restoring (some would say resto-modding) an older Delta wood lathe. Since I rarely use the outboard shaft, I decided that a handwheel of some sort might come in handy. The outboard thread on my lathe is 1" - 8 UNC left hand.
I printed it in four pieces and glued up the finished product. I did it this way to avoid having to use supports. If that's not your cup of tea I've also included a one piece handwheel.
The author marked this model as their own original creation.
