I want to make some oval gaskets with about a 2 inch center hole and 2 10
mm stud holes. I need to make multi layer stainless shim gaskets, it's for
a turbo to manifold type application where the interface will be cherry red
hot a lot of the time. Only multi layer shim gaskets work reliably. What's
the best way to cut say 5 thou thick stainless sheet without burring it? I
need to cut the oval outline, the 2 inch hole and the 2 ten millimeter stud
holes in about 5 pieces of material. thanks.

I would probably sandwich the gasket material between two other pieces
of metal, maybe 1/8 inch thick steel. Sandwiching should greatly reduce
burring, since the edges are fully constrained. I might still expect to
take a dremel with a small stone on it to clean up any edges that felt
rough.

Sounds a good application for laser cutting.

We use tinner snips at work for cutting steel shim up to about .020". Sharp
snips will reduce the burr to almost nothing. You can remove what's left
with an oil stone easily.

As for the holes, we use shim punch and die sets. Any professional die maker
should have one. Perhaps you have a die shop near you, or know someone who
is a die maker? If they're sharp, you'll get very little burr which can also
be removed with a stone.
