truing pressure plates

[Merk]

a woodworker will do final prep of a chisel or planer knife using fine grit sandpaper that is taped to the machined surface of his table saw or even a piece of glass, so it is super-flat. Our tiny 'O' pressure plates easily fit on our 12" stationary disc sander (not a belt or palm sander which I agree would be nearly impossible to keep flat) and with a gentle hand, came out just fine. All we were doing was taking a few thou off of rust and grime. And, we also 'kissed' the clutch material as well to take the shine off of it. Our clutch works flawlessly, even with double the horse power and original spring, it does not slip.

This isn't woodworking and you are talking about 2 different things. There is a huge difference on how you would sharpen a chisel and how you tru a pressure plate. Number 1 thing is you use a different tool to do the job. I use an oil stone/hone to sharpen a chisel.

It is next to impossible to have the same pressure all the way around the pressure plate. on a pressure plate(s) when holding them against the sander. That will leave high and low spots on a pressure plate. You need to take off more than a few thou to remove the high/low spots, rust and grime.

Not what shine you are talking about on a clutch disc. Taking the shine off will leave high and low spots on you clutch disc.

There are several places to have your pressure plates trued if you are unable to do them. One is one of our sponsors at the top of the page. B. Miller's pulling site is another. A local shop should be able to do that for a small fee.

Can you post a few pictures of this O with the 14 hp motor?

A up to date AUTO machine shop uses a special oscelating flywheel grinder , quite a big machine for flat flywheels and a geared milling type grinder wheel for resest fly wheels . the later would be a good match I think . Oreally has them
