I will have to visit the print shop where I work... they have very expensive heavy stock for maps and posters...... not to mention raiding the supply cabinet for heavy brown file folders.

I have had good success with heavy craft paper.... coating one side at a time with silicon... let it dry... then cut to size... they hold up well.

Canadian Tires store in Ottawa still carry rolls of various thickness paper gasket material.... I better stock up. I found a good supply of gasket material at old gas engine and steam shows.... including asbestos material..... usually old stock or the left over after someone has cut out a huge gasket. For example I got a center cut out about 4 foot across... a cloth neoprene material highly resistant to fuel/oil etc....

Princess Auto still carries cork... but nothing thinner than 1/16 and yes you almost have to steam it or soak in hot water before you can safely handle it.

How critical is the thickness of the stock material..... assuming thickness would not affect gear spacing as in our case...??
