TNC Lathe renovation 2
Some progress on the little lathe.
A complete disassembly, and separation of the parts to be repainted.
Some unwanted holes were filled with steel putty (similar to JB Weld), and filed flat after hardening.
Then further filing of the parts, a soaking in degreaser, and then a wipe over with acetone.
Then a coat of undercoat, from a spray can.
Making the larger handle, the one for the leadscrew was a learning exercise. I planned it in brass, with a counterweight to the handle. Drew it up on CAD, then tried to make it using the Boxford CNC. The end result is not perfect, but it will do.
I discovered that it is quite difficult to turn complete balls on each end and avoid chatter. I used a carbide cutter. Perhaps HSS would have worked better.
First result goes in the rubbish bin.
I finally turned one end, then made a split collet, and turned the other end. All done using CNC.
I admire your work John. Prepared to undertake the most difficult of jobs without a whimper. SUCCESFULY,in the end. Our hobby needs more with your outlook Les M. of gsmee
The whimpers turn to expletives when the tooling gets busted!
But I appreciate the compliment Les. Thank you.
