Doing a freebie job to help a friend, her brother paid for the parts, but as he's a chebbie racer, said she don't need a flywheel.... my Bro helping me tried to scuff it w/ a 4" angle grinder.... wheel was dead. It's slick otherwise, except for the long humpty circles... is there anything I can recut this with at home? Thanks, Yall! And Happy Thanksgiving!

I have a diamond cup tool, for cutting concrete, goes at a 90 from the frame of a angle grinder. The problem is, she wants to see her daughter, about 240 miles away, this weekend, so could I "dress" this so it won't be a further issue. I know we ain't doing it twice... wasn't bad, in 3 hours, had it down to what ya see..
 
A round roloc buffing pad in a circular motion. NOTHING any more aggressive. Either something like that OR leave it alone.Whatever you use, needs to be non directional. In other words NOT like a brake lathe. Make sense?
 
...and whose idea was that CRAPTASTIC clutch disc? a 69 dollar Autozone special is better than that.

That's what I pulled out... think it was stock. It was another member of the family's ( brother she was really close to) that passed away some years ago....

Stock? What's this in?

Does that mean, ol.Doug hitting it w/ a burnt wheel, and having her hit it with a hand sander, using 180,and a scrap piece of 80 drywall paper? The truck was in a field in Zephyrhills, we didn't have alot to work with.

Anything you can put a swirl pattern on it with that doesn't actually remove material and breaks the glaze. OR leave it like it is. There's no bluing on it that I can see so it's probably ok.
 
May I ask, "What grit are you using?" Please? Lol
I don't remember, I'd have to look in the tool chest drawer. Probably 80... and that was done with the lathe running so the cut is nice and even. I also did the pressure plate. My Bee's clutch has never worked better..
 
I don't have access to a lathe this weekend.. sucks Machine Shops are about gone. But getting one turned between now and Sat is kinda a tall order... what's the worst that could happen, if I hang it from a wire , and have someone turn it while I hit it w/ a grinder? Will it eat the disc too soon? Crack the flywheel under heat? If it's not gonna be safe, I can't, even helping someone out that's down, put it in, and say go. That's not me, and I just ain't that way

That's funny, I was telling the owner to dig for 80 for the DA, earlier today... Hey, wait a second? Would that work?
 
Now THAT I'll endorse. Simply because you're spinnin the flywheel on something. Looks good too!
Think I just answered my own question, so if her flywheel, ain't Flat, that'll probably eat the new disc, well before it's time? Just kinda an educated guess..
 
If you don't have a lathe in your garage, a D.A. with a Scotchbrite pad and plenty of brake cleaner is about your only option at 11 pm on Thanksgiving eve... or like Rusty said, just run it as is. Hell, it's an Amigo, fer cryin' out loud... :)
And you're better off, and safer too, just leaving it rather than trying to hand grind it. You really don't want to remove ANY material, just dress the surface or you'll be headed to chatter city.
 
Flex hone makes a dingle ball tool for rotors that might work, might be able to find a parts store that can order you one in overnight?

That or sandblast would be my first bets if you don't have a way to cut it evenly.

If it's not done well, worst case the clutch let's go as she's shifting down the on ramp and winds up roadside on some freeway. If there's lots of stop and go between home and the destination, I wouldn't hold much hope that it lasts with a "flat as I could hold it" grinder finish.

You might could spin the thing by getting handy with some ratchet straps and a jacked up rear end in-gear at idle.. Not that I'd recommend such shenanigans.
