I just bought a dv-59 dovetail bed lathe with a compound slide and a regular tailstock. It came with a 5C collet closer (but no handle lever so I have to spin the handle to tighten the collets) and about 30 odd hardinge 5C collets in good shape plus a 3 jaw chuck that fits the camlock spindle nose.
I am wondering if it would be possible to make a carriage for the dovetail (60 degree I believe) with a leadscrew and servo motor to allow continuous turning of long parts between centers or even to allow threading via an encoder on the spindle and a little microcontroller (easy) to move the carriage X inches for each revolution of the spindle.
I have never cut dovetails before, but I have a nice rigid cnc Shizuoka bedmill. Do you just buy the right size dovetail cutter and go to it? Wish I knew someone with a shaper and a good eye for grinding...
The other option would be to make a plate that clamps to the dovetail bed and has linear square rails and carriages to mount the compound slide. Seems like this would just add more complexity...
Is the dv-59 dovetail exactly 60 degrees or is it some funky 58.25 degrees or something?
If anyone has a lever handle for the 5C closer they want to sell, drop me a line. (Gunner?)
