I spoke to 2 more motor rewind specialists today, ones who say that they do obsolete motors. As I had hoped/expected they just said "no problem". A rewind is more expensive than a new motor but if I bought a new motor it wouldn’t fit straight on so I would need to fabricate some sort of adapting plate or modify the motor so I think its worth the extra cost.
Next I need to look at replacement hand wheels. The one on the right end of the table is just a keyed fit so a new handle (which will come with just a small hole in the centre) will be simple to do. The other one, the one on the knee, is splined. I haven’t made a splined hole before, I think I can mount it on my lathe and, if I can work out how to index it, cut the spline with a form tool in the toolpost. It is a 36 spline fitting, my question is, are splines a standard geometry? I assume that they are. I want to sort the handwheel out before the machine is back together to I can offer the shaft up while the wheel is still mounted in the lathe.
hermetic, can I ask a question. You say that you have a similar machine. What size handle or wheel is on your knee? I want to fit one as big as possible on the knee and before I took the machine apart I estimated that a 12 inch wheel would fit. Does this correlate with your machine, would a bigger one fit?
