At the moment its using m8 threaded rod and delrin nuts. My upgrade to trapazoidal leadscrew and delrin anti backlash at some point to gain some speed. Running at 24ipm at the moment. Slow but accurate.

Fine drive nuts they are to ;).

Actually quite a bargain given how much messing about was involved to make nuts before. The best thing about these is how easy they are to mount.

Have you thought any more about making round ones with a flange(im sure thats what they call the surrounds) or even better antibacklash ones using a split end and a spring?

[Lee Roberts]

I dont have a lathe so i could't put a flange on them :(

Would a wood lathe cope cutting delrin ?

[Lee Roberts]

I've heard so.

You wouldn't be able to make round ones even without a flange without a lathe either.

Skit

Yes i could, good old fashion hand tools.



I will be making some ali round standoff's this weekend so this is how i will be doing it....using a Center Square.

this is quite interesting for a cheap way of making a lathe or even a 4th axis
