Ok guys i learned this trick from an old autoshop teacher.
you take the gasket material and lay it on the surface it's going to go on.
next you take a small ball peen hammer and tap around the edges just enough to
cut through the gasket without deforming the surface you want to seal.
it makes a perfect gasket every time.
with aluminum you have to be carefull not to hit too hard or you may distroy
the flat surface you want to seal.
i have used this to make head shims out of beer cans for several engines and
they came out perfect.
you have to pick the gasket material for the intended use, for cox .049's i use
the waxed paper from inside a cerial box, for larger engines i use brown paper
bags, for even larger i use the cerial box or a playing card.
all that matters is that it has to fit right and be thick enough to seal
the rtv idea is a good one, but you often break the gasket when you take it
apart again, i usually just use some oil to get a good seal.
I hope this makes life a little easier for you.
Keep them flying!
