SWMBO has “persuaded”me to make two sets of double gates for a Norlane renovators dream, so not too much happening in the machine shop. Welding and cutting in our Australian summer is not fun. The gates are ready to be hung so hopefully I might be allowed back into the play area in a couple of days.
I did get a few hours to put some colour onto the TNC lathe. Dark green enamel sprayed with a “Badger 360” air brush. First time. Fun. Not a fantastic result but OK.
I was quite impressed at how effective masking tape was, in keeping paint off machined surfaces.
This whole exercise is a practice run, so I minimise the chance of stuffing up when I paint the Beam Engine.
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.
