Paul, just a thought, the DREMEL company has a bench mounted
router table. They also have diamond
 point bits. Could the materiel be machined by placing
it on the table and passing it by the diamond point
bit to square it etc, Virg

Might be worth a try.

I can't imagine how you would do better than the Mazda racing apex seal, but if you must,why not track down the people that make the McMaster-Carr piece and have them extrude some Apex seal looking rectangular stock a bit oversized and have it ground to size on conventional equipment? Or, maybe they already do have stock close enough to the right size. Lynn E. Hanover

Are you referring to the carbon apex seal Lynn?

Paul Lamar

Right, the carbon seals. We had one engine with the ceramic seals but they have to run with a second shorter seal spring (why I don't know). We had two identical engines built and the second was with stock weight rotors and carbon seals. The second engine outran the first on the dyno and on the track at much less cost. Lynn E. Hanover

That is very interesting. Iannetie claims the ceramics are better
and don't wear. Are the carbon high wear? Do you think
the carbon seals will hold up under a turbo charger?
Are they expensive?
