- threading 16tpi, half nuts sound wrong at the end
Same family of lathe. Don't ride the half nuts through the shoulder if you didn't cut a relief groove. You're asking them to climb out unde…
- 16 tpi external, the dial doesn't land where I left it
Indicator on the slide. Same direction every pass. Gage is less theatrical. The dial is now a decoration I still look at, like a clock in a…
- 16 tpi external, the dial doesn't land where I left it
Threading 1/2-20, which is 20 tpi, sorry, the title is from the last panic. The cross slide dial does not come back to the same number afte…
- leadscrew has end play, the thread length drifts
Took the play down until a push is barely a wiggle. A 1 inch thread is an inch now, near enough that the nut doesn't argue. Counting was al…
- leadscrew has end play, the thread length drifts

- logan carriage binds in the middle
Carriage is smooth at the headstock end and at the tail, and right in the middle it goes heavy. Same spot every time. I oiled it. I backed…
- 1/2-13 on the logan looks drunk
The nut goes on. The gage was rocking on a torn crest. I shortened the stickout and took a lighter pass and it looks like a thread a person…
- 1/2-13 on the logan looks drunk
Trying to cut 1/2-13 for a drawbar nut. The thread gage rocks. It starts ok and then the pitch looks stretched by the time I'm at the end o…
