| 750 forum posts | Sid, Have you seen the fine feed arrangement Martin Cleave came up with for his ML4? If you just relocate the banjo to a lower position for the motor drive onto an aligned pinion gear it still leaves open the possibility for thread cutting and you can also use the leadscrew handwheel if you need it. Here's a bodge I knocked up to test the idea and it worked ok but my motor was restricted to fixed speed only which proved too inflexible.
Hopefully you can come up with a better idea. MrPete222 on YouTube has a motor driven leadscrew on one of his lathes but I can't help thinking that the leadscrew handwheel is too handy to make obsolete for me but we're all different I suppose. HTH Jon Edited By Jon Gibbs on 15/03/2017 11:27:00 |
