Lathe build project

<< < (7/8) > >>

NormanV:
Thank you for the suggestions. I don't think that it is worth my while making one of the linkages for thread following as my requirements are very rare and I am more interested in fitting it with a fine feed to save me from having to wind the handle all the time. If I have fine feed it is just a step away from thread cutting abilities. The Knaell device is enough information for me, it is practical to do it with timing belts.
I need to do some measuring and sit over a list of timing pulleys to see if I can fit it all in. I also want to incorporate a dog clutch on the end of the leadscrew, this lathe does not have half-nuts to disengage the drive.

NormanV:
I've had a look at it and it appears that I could set up to cut .75, 1, 1.5mm threads and a fine feed of .1mm per rev. This would need six pulleys and four belts and cost just under £50. That doesn't sound too bad.
I will file away the sketches for a later date.

NormanV:
Work has come to a halt on my lathe. I am moving house shortly and will not have a workshop for a few months, but when it is built I will be back to work!

vtsteam:
I know the feeling, Norman. Looking forward to when you resume. :dremel:

There is a simpler threading method using the follower principle: http://cartertools.blogspot.com/2011/01/monty-remons-taig-lathe-mods-part-2.html

This works very well on small lathes. I have used this on both my Unimat and Taig.
