G'day All
I have finally gotten around to using my lathe for the first time in over 5 years. Long story involving an ex wife and near bankruptcy because of said ex wife.
Anyway I've moved all the gear I managed to keep three times in the last five years. I remarried almost two years ago and my new wife and I have been spending a lot of time renovating the old house we have. Every now and then I have been able to fit in a little time in the shed, slowly getting it organised.
During one of the moves about three years ago I very cleverly managed to let my drill press get away whilst unloading it from the truck. When it finally came to rest on the floor, the only damage to it was some paint scraped off and the handles broken off the quill feed.
Its taken me three years to get to repairing them. When I refurbished the machine about 20 years ago I made new handles for it.The only material I had at the time were some shafts from old car shocks. Unfortunately, at the time, I only had enough chrome plated shaft to make 2 handles so the 3rd one is unplated.
My lathe has been covered up for quite a few months and when I uncovered it the other night I discovered I hadn't oiled it up as much as I thought I had. Hence the small bits of surface rust you can see in a couple of pics. (since removed).
So I just removed the knobs from the broken shafts, chucked each one up in the 3 jaw, machined the end down to 8mm dia X 12 mm long and rethreaded using an 8 X 1.25mm button die. Pretty simple job - except I had forgotten that the shafts were case hardened. Started off with HSS which the shaft laughed at. So I had to use a carbide to gnaw it down to size. I normally dont use carbide in this little machine as it just doesn't have the power or speed to use carbide well.
For those just starting out into machining, I used a split button die in a holder (stock) and used the end of the tailstock ram to hold the die square to the end of the shaft. I turned the tool post so that the edge of it (actually in this case it was a bit of packing under a tool) was parallel to the machine spindle axis, wound it out to a point where the end of the stock handle could rest on ledge. Released the belt tensioning lever on the spindle and turned the spindle by hand using the chuck key. ( I also ensured that I had tured the power off at the wall before doing this). You just have to keep a little bit of pressure on the tailstock ram until the first couple of threads have been started.
Once all three were done just put it back together. All three are now about 12 mm shorter than they were but its not noticable.
I hope this info is of help to someone.
