DIY OD Grinder fixture, For the surface grinder- maybe

[Janderso]

Made one of the o-ring pulleys this morning.
I see most of these fixtures use oring drives. I hope it doesn't slip.
If it does, back to the flat belt plan

Thanks to Jim Sehr for helping me with the form tool

Looking good Jeff. I need to get back to working on mine.

Hey buddy,
I see you went with the flat belts. Probably a good idea. I had the material to make the oring type pulley but I couldn't figure out how to make the flat cog pulley. I'm afraid it's going to slip.
I guess if I take .0002 - .0003" at a time I may be OK.
Where did you find the pulleys? The belt?

Thanks, Jeff

Hey Jeff. Ironic I started working on mine again. Working on adapting motor #3. But what a pain this has been. I got the pulleys and belt from McMaster-Carr. I went with 1/2 wide belt.

I am working on the pulleys.
Bit by bit , it’s coming along.
