Is there a source for draw bar sleeves to protect the spindle while using a draw bar and collet?
I agree. I also use cones on my lathes and haven’t experienced any issues.I use draw bars often and have not seen any damage to the spindle. I do use a cone on the outboard end to keep the threaded rod centered in the spindle’s tube, but that is more for ensuring that the pulling direction is centered and not towards one side.
What is your concern (i.e., am I missing something I should know about)?
This is simply brilliant! The knob at the end of my draw bar gets pretty wild--now I know how to secure and tame it. Thanks, Rich.I do use a cone on the outboard end to keep the threaded rod centered in the spindle’s tube,
Jerry, how about a piece of clear plas
I may be concerned about nothing. I use collet chucks regularly and I have heard that it is best to cover the all thread rod. The cone is an excellent idea.I use draw bars often and have not seen any damage to the spindle.

When my lathe was new I didn't want to possibly scratch the female Morse taper in the spindle with the all-thread rod. Probably not a big worry ... but cheap insurance ... and looks nice!I’ve never covered the draw bar. My draw bars are all thread and I use a wooden cone to press against the outboard spindle and a wing nut to pull the draw bar tight.
The leading edge of the drawbar would be the part most likely to touch the inside of the spindle as you pass it through.
You need those threads uncovered to put the tightening nut on the draw bar. So you would want some sort of cap you can put on an off.
If you need a cover, A nylon nut screwed on 2-3 turns should work well and be easy to get out of the way to secure the tightening nut.
