On the little wood lathe we have lost the inner insert to the live center.
But luckily, we have just the tool for fixing that! A lathe!
I mounted a rod of scrap steel to the lathe and turned it down a bit.
Once I got close to diameter, I turned a point then took it off the lathe to double-check the fit.
I parted it off, here it is ready for assembly.
Luckily we have a box of set screws. I found a matching setscrew and installed it!
I should probably do it again, because I can get the fit a bit closer. I should learn how to use one of those inside hole sensing devices to get the exact size, because I don’t think I got a good measurement from my calipers. There’s a slight bit of wobble, but it is better than we were (without one). I’ll probably remake this at some point, but now we have something that works.
