These mini lathes have a slight problem. While I was installing my 20 TPI conversion and new compound, I decided to fix it once and for all. Lets look at that problem, and how I solved it.
On the compound slide, the moving dial can (uh...will) bind against the stationary dial (see the pointer). What this means is that you can't always trust the reading. I don't run a DRO on the lathe, I never have. I have this thing about DRO's on lathes, I don't know why. Anyway, I rely on the dials.
The cross feed screw does not bind up. Hmmm...but why? As it turns out the cross slide screw is captured by the thread housing (for lack of a better word). The screw has a shoulder, and that shoulder is used to limit the movement of the screw. The compound slide lacks this feature. So, no matter what, the screw will bind against the dial as you feed in.
