Threading dial problem

[ome]

It shouldn't really matter whether it lines up on a number or not as long as you flip the lever at the same time it's just about to line up or whatever. Actual alignment of the number and the mark isn't important
All that's important is that the number and the mark are in the same position relative to each other every time.

Someone recently did a YouTube video meant to demystify the threading dial recently.

The creator of the video is a regular on this forum.

I was recently reading a book on lathes, and it referred to different threads might be on a odd number and others may be on the even number. so I naturally thought there was a reason for the numbers on the dial face.
I agree with you, with the little I know from limited threading, its all about throwing that half-nut lever at the same place each time.

Thanks,
Jon

I just took a look at the dial on my Logan 11" and it looks like the shaft is as TomG said. It looks like if you could press the dial off the shaft, you could rotate it a bit and press it back on to realign it with the gear.

Thanks,
would i need a special type of gear puller or like a 4" spider like puller.

I really don't know. I couldn't see any way to take it apart other than maybe a punch to the end of the rod in the middle of the dial. the gear at the bottom is shrouded, so I don't think you could get a puller behind it. I couldn't find any references to how they are disassembled on google either.

Thanks anyway, i could not find anything on google either. A punch looks like the only way to get the gear and shaft, once knocked out, i guess i need to somehow press the gear off and then press it back on , but in a different position..

You shouldn't have to remove the gear. You should be able to just press the rod back into the dial with a different alignment. From TomG's picture, both ends are press fit.

My old worn out Logan had the same problem. It just wouldn't catch on the line. After thinking about it I just decided it doesn't really make any difference. If I need a line or whole number I just flip the half nut on it but it would'nt engage until the number went by for almost a quarter inch. So what? As long as it does the same thing every time you're golden.

:+1: As for pressing the dial/gear back on, that's the simple part. All you need is a shop vise, hydraulic press, or you could make a "fixture" to hold things in alignment while tapping it back on with a hammer (redneck version of the "right" way to do it ).

How about some pics of the dial assembly you're working with?

Thanks guys,
Still not sure what tools I would use to accomplish this task.

Checked out TOMS WEBSITE and it cooks. Great teachings.

Thanks,

FWIW - I left at least one out - I've used a large "C" clamp to press smaller items together before.

Sorry I can't help with the iphone/pics thing as I'm allergic to cell phones and don't have/use them. :biggrin:
