G0704 CNC Conversion - C7 Ballnuts - Question

[MontanaAardvark]

I used the same custom low profile elbow for the Z axis, I attached the drawing. It's a brass banjo fitting sealed by 2 small o-rings. I soldered a tube into a 3/8" rod of brass, then bored and counter bored it. The other fitting is self explanatory. They work pretty well and you can turn them whichever direction you'd like before tightening. I'd have to lookup what size o-ring I ordered.

That's a good idea.

There's a guy on eBay who sells machined ballnut mounts for the G0704 and he adapted an interesting, simpler idea that seems to work. The hole is M6, and 6 mm is 0.236". Just use a short piece of the plastic tubing with an OD like 1/4" or slightly larger (9/32?) and thread it into that hole. He brings that short piece to a though fitting in the front of the vertical slide.

On my PM-932 conversion I drilled and tapped the brass fitting that came with the ball nut to accept a 10-32 and used a miniature swivel 90. https://www.mcmaster.com/#5483t11/=16rqs3u

The push-to-connect fitting is 10-32 to 1/8" tube. https://www.mcmaster.com/#7880t137/=16rqx3k
