Making progress on Harold Hall's tool grinding rest. May be I should create a separate thread while things are fresh in my mind in case it helps anyone else interested in making one.

Setting up for creating a 30-deg ball seat in this flat. I had may be a few mm to spare on my 9" lathe - definitely a pucker factor in case the setup slipped but 120RPM, .005" cuts and lots of patience won this game. Now I have to make another one to match...

Double and triple checking the angle lol

Steady steady wins the race Stioc looks like your getting the results.i actually made a radius tool for my lathe a while back .I designed it to be able to cut radiuses or concaves in which your case would serve the purpose well.

I made a tool like this one

Steve Bedair's 9x20 Lathe Site

but didn't think to use it, perhaps because I'm too lazy to remove my compound slide etc. Plus it's good practice, just in case I ever get stuck somewhere where my only means of survival is a lathe without the radius turning attachment LOL

So I purchased a new clutch pressure plate that was advertised as fitting my old truck. I received it this morning to find that it will indeed fit but only after the flywheel is drilled for a new bolt pattern. I started to freak out and then thought I can do that. I have a DRO on my PM932 that will compute bolt circles but the flywheel was too large so I had to use my rotary table. Worked very well but it required centering the rotary table and then centering the flywheel on the table so it was a little more putzy. I also power tapped for the first time and that was sweet. All the holes lined up perfectly. Now just need to install it all back in the truck. That's for tomorrow.

Always a scary proposition! Do you just send it back or try to modify it to work?! We all have faced this dilemma many times. Great work on this.

Thank you Robert. That's not a bad idea but I'm actually making some table covers as well right now to keep the chips out of the T-slots on the table. This one actually just ended up being the prototype as there are few things I want to to differently and begun making the second version already.

I did exactly that. Now after knocking over my oil can several times I am ready to bolt it down!!!

The bolts should be roughly equally spaced around the flywheel, but you might still want to balance the flywheel, as it spins at up to roughly 6K rpm about a foot or so from your body.

Good Job!
That's using the old noggin.
I don't know if I would have been able to pull that off. That's touchy work there.

We are talking about a Ford flathead that will never be turning 6K, more like 3.5K tops. The flywheel has been resurfaced and balanced. The shop says that they don't balance diaphragm pressure plates on the flywheel.
