Both of my brothers recently picked up a Logan 10” lathe, essentially model 200’s.
Neither machine came with a threading dial, so I offered to make two copies of the one on my Montgomery Ward / Logan lathe.
1st order of business was checking my stash of small gears. As it turns out, a 16 tooth, 24 pitch spur gear is a spot on match for the stock gear on my machine - I had two of them.
Next up, it was easy enough to measure my existing threading dial and raiding the metal scrap drawer to see what I had to work with. Some mystery steel 1-1/8” rod and a bit of 3/4” square stock would do the trick. I also had some salvaged bronze engine valve guides to use as bushings, and some 5/16” drill rod for the shafts.
Here is the progress to date.
I am now working on the dials themselves and need to silver solder the two pieces of the main body together. The part that the bolt passes through is at a 3 degree cant from the dial/shaft/gear housing so that the gear teeth mesh well with the lead screw.
More later, but I’m pleased with how it’s coming along.
