Some more ideas needed for flywheel welding problem

factory flywheels are generally cast. This is a fool's errand

Ever see a clutch/ flywheel explosion? I have. I darn near got a piece of flywheel through my windshield, here's the true story:

Approx early spring of 67, the old "Deer Park" dragstrip N of Spokane, a cold and windy day. We had gone to the car to warm up, parked along the strip. I'm trying to watch and read a program, when the old "Ron's Drive in" coupe went by, my partner shouts "Ron's blew a clutch!!" I look up to see "junk" coming down out of the middle, an old ?? Olds ?? jacked up in front. Several seconds later we hear a crash.

Get out, the '59? Caddie parked next to us had a BIG gash in the rear quarter nest to my car. A big 'ol smokin' hot piece o' flywheel was laying on the ground. The piece had come right between our two cars and gashed the quarter of that Caddie next to my car.

I had a great paperweight for years. Somehow, it got lost

Just got back from Google. Here's a picture of that very car
