I used to do a lot of small diameter tool post grinding on punches, dies and small technical ceramics at my 1st tool room job back in the 70's. I never did anything with a wheel larger than 3/4".
That frame of mind pops up every once in a while in the home shop and I wanted some of that capability but not the cost of the Themac grinder I liked so much.
I have a bunch of big aluminum bar out in the shop so I whipped this up to hold one of those long stem die grinders on my AXA tool post. It's loud as all get out but then that Themac used to wail like a banshee too. Now I gotta make some way covers to keep the grit where it belongs.

Tim,
I see what looks like an air grinder with a separate spindle in your tool holder. What is the spindle that the air grinder drives and how do you couple them up?
Thanks,
Brian

He used a "long stem" die grinder. They have a long housing on the front. Great for a tool post grinder, nice job Tim.
Look about half way down the page for examples.

In a effort to cut down on the chips flying everywhere on my lathe, I made a chip guard that is attached to the carriage of my Craftsman 101.21200 (6x18 Mk2) lathe. When I had the carriage off to drill and tap for the ways wipers I previously made, I also drilled and tapped holes on the back of the carriage so I could mount an indicator. I am taking advantage of that to mount the chip guard.

Nice job on the chip guard. I have one on my big lathe that is a factory made one and it mounts on the workhead instead of the carriage like yours. Yours makes a lot more sense as it travels with the tool bit and keeps chips down. I may retrofit mine to work the same way as yours.

An old crankshaft needed some attention. It is from a seawater pump for the Steamboats condenser - the boat: DS Styrbjّrn.
So the bearing surfaces was polished with some shop made Tools/solutions.
You will see that the pix are marked NJK fotosamling - thats because I uploaded them there.
Excentric chucking solution.
Polishing, rig made inhouse - spindle bearings from SKF.
More polishing.
The finished shaft.
