That's what I was thinking of. It's basically what Hoss does on his DVD, except his is 3D printed, too. A tube with and ID that will pass the machined end of the ballscrew and slide over its end, but has an OD smaller than the minor diameter of the screw. Then the ballnut is unscrewed onto the holder, trapping the ball bearings.This is what I do to remove / re-install the ball nuts. http://www.hobby-machinist.com/threads/linear-motion-double-ball-nuts.46041/#post-392452
No, I have a lathe. I just don't have any stock of that size to turn. I'd have to order something. There's no place locally (that I know of) to go get some plastic stock to turn, unless it's something the big box home centers carry.FWIW I opened the file for the ballnut removal tool (tube) and it's .53in or 13.46mm. My guess is a piece of 1/4" pvc sched 40 would prob work. They show it has an outside diameter of .54in with tolerance +/- .01"
Even a piece of hose or vinyl tubing with a 1/2" outside diameter should work... especially with a little duct tape if you need to enlarge the diameter a little. Just guessing you don't have a lathe or this prob would be a issue at all.
Probably not the best for grinding steel, even hardened steel, they tend to load up quickly and then just make things hot. Diamond is great for grinding rock, glass, and ceramics. The better choice for steel is just a standard 36 grit grinding disk.Used a diamond grinder.
I left out a word. I used a wet grinder that was designed for grinding rocks. The water flood washes the grinding dust out constantly. No one in their right mind would go buy one for this use, but since I have one, it was convenient and worked well.Probably not the best for grinding steel, even hardened steel, they tend to load up quickly and then just make things hot.

If you have Hoss' DVD, he has a smaller chip tray in the "Projects" folder. It's shorter front to back, and the Y axis motor sticks out front, and 59" left to right while the new one (like mine) is 5" longer. 5'4". The left to right size is pretty much fixed by the length of the table with the X-axis motor and Hoss' mount.Nice job on the chip tray. I wish I had room for something that big, but as an alternative I'm planning a smaller partial (1/4 to 1/2 height) enclosure. I plan on getting a new tig welder soon so thought I'd make it my first tig project and use aluminum. Be sure and provide some photos when you get yours sealed and mounted!
