Jim:

The price for a gasket set is ridiculous. I bought one set, then I searched for cork gasket sheet. It wasn't easy to find, but after asking at two or three auto parts shops I finally found it. Apparantly no one makes their own gaskets anymore.

It is cork, but it also seems to have rubber impregnated in it. So it should last much longer than regular cork.

I used the new gasket as a pattern and then cut out a couple of spares with an Exacto knife. I now have enough cork left over for about 6 more spares.

David makes an excellent point.  All too often I discover that  parts,
gaskets,  etc  for some older piece of equipment is no longer available.
FelPro is one manufacturer who does supply  gasket material in sheet form.
I get mine from an automotive supply house. MAPA and Autilite are two chains
that do carry this product.  It comes in various thicknesses.
One problem you will find is cutting out the smaller holes for screws and
bolts.  A die cutter hole punch  is essential for this. Look to  leather
craft stores or a good  tool shop  for such a hole cutters.  The plier type
hole cutter is good  for  up to 1/4" diameter holes and  my die cutter set
goes from 1/4" diameter hole  up to  1-1/2"  The latter is useful for
cutting clearance holes for shafts  etc in gear case housings.  Use a hard
rubber backing when  cutting with this kind of cutter. Otherwise you dull
the edge too quickly.

Gasket in a tube is also useful  but not always.  don't try this on
injection pumps or caburetors where  bit of the RTV could get into the
inside and clog something.  Locktite and Permatex  has RTV  in several
grades.  Blue, black, and red.  Although nominally  silicone based  each
has specific characteristics.

What I did about 8 years ago is clean out the groove for the cork gasket and
filled it with silicone, smoothed the top surface and let it cure for a day
or two.  Works great.
