On the way home from work Friday, this idea came to me.
It seemed a simple and cheap solution for manual mills in my noggin
so I bodged it together and it works.
YouTube- G0704 Manual Auto Drawbar
If I was going to keep the mill manual, I'd make a better crossbar that pivots,
would allow for drawbar removal, a tad more quill travel and keep the drawbar from rubbing.
It's for "Light Duty", well as "light" as my X2 can handle anyway. Read # 16
If you want to use stiffer bellevilles, you better bolt the machine down.
I could manage to compress the ones I used (left over from the X2)
with just forearm strength, about 750 lbs at the drawbar.
Works as quick and easy as the Mach 1 system but not as much $$$.
Should work just as well on X3's, RF45's or any other mill with a quill.
I was worried the quill handle might break but it seems more stout than I thought.
If I went with higher spring pressure, I'd replace the handle I'd use with a solid steel one.
I wouldn't be worried about trying to get too much more though, I know what Can be done on my Freak with these springs.

Hoss, I have watched your videos for seemingly ages. This drawbar mod is brilliant and after looking at the pieces, is it really that easy? So the collet (a Tormach? Or are only the toolholders Tormach and any collet could be used?). I plan on buying a G0704 in the next couple of months. It seems like with a stepper on the quill, it would be great for a silent auto tool changer  Any changes that you could see now in the MAD?

The newer version flips down out of the way. It does need to use a tormach tool holder or a 3/4 shank tool. the 3/4 R8 collet is released but not removed. Hoss G0704 Quill V-Belt Drive with MAD Drawbar
