Are people still having problems with the gasket burning out? It has 
been so long since I drove my car, I can't recall how much fun it is 
to replace the gasket.

Not wanting to find out, I am thinking about making a bunch of copper 
gaskets. A friend has a machine shop and he tells me it is easy to 
make them with a CNC machine. So... I have some questions:

1. Are the gaskets the same shape and specification for the BT7 and 
BJ8; or other models for that matter?
2. Is copper the best material or are there other materials?
3. If copper is the choice, what type of copper?
4. How thick; what gage or mm? I know I could just mic a new 
after-market one but I want the list advice.
5. Presuming others might what these gaskets, what would people be 
willing to pay for them? I don't need to make a profit but it would 
be nice for the machine shop to get paid for labor which is mostly 
inputting the dimensions into the CNC program, the cost of materials 
and loading and unloading the CNC machine.

Any and all advice would be very helpful.

Thank you,
