I was off the list last week and missed the thread, but maybe these 
comments will be of help.

I make brass shim gaskets for the bottom of the liners all the time. I buy 
it by the six inch by six foot roll from McMaster-Carr in Chicago, who by 
the way must have the best website and fastest service on the planet. They 
have millions of items in their on-line catalog, it's easy to navigate, and 
the shim stock I ordered from them last week took only one day to get to my 
door. .010 works most of the time for the deck height I wants.

I make them by laying a stock fig 8 gasket on the shim and scribing a line 
with an awl. I make them round rings rather than fig 8's also.

I cut them with regular aircraft tin snips. It ain't easy, but it's the 
best I've found. I have not been successful in doing it with scissors but 
that would certainly give a better cut. It would take pretty good scissors.

Getting the inside cut started is one of the difficult aspects, since you 
have to have a hole to start with. I've tried cutting a triangular hole 
with a chisel which doesn't work very well, cutting a hole with a hole 
punch which doesn't work very well, and using a two-edge sheet metal hole 
cutter which also doesn't work very well. I'm still looking for a method 
that does work well.

The next problem is getting the inside hole big enough -- seems that I 
always have to touch it up with a stone in a rotary tool grinder to get 
them on the liners.

Nevertheless, despite all this whining, the last set I made only took about 
an hour.
