Is that a common gasket material? Can I make a new one from ordinary gasket paper or is there a special stuff?
Due to the heat of course, ordinary paper gasket material is useless underneath a glow engines cylinder head. It sounds as if someone has removed the head, ruined the original head gasket in the process, then fitted a paper one to cover the mistake up. The proper head gasket material is now getting hard to find in the thicknesses used in model engines, but occasionally you'll see small packets of "Perfect" brand gasket material on eBay. If the original head gasket was thin, you could try making one up from the soft
aluminium foil that's found as an air seal inside the top of Nescafe coffee tins. Ordinary aluminium from soft drink cans is too hard. If the original gasket was thicker (about 1/32 in.), you could try some of the stuff shown below. Now, this was given to me by a fellow aeromodeller who told me it is suitable for high temperature head gaskets, but I have only used it on non-running display engines, so cannot vouch personally for its effectiveness. It has a sort of plasticky feel like lino, and as shown, is bright orange on one side, with a 1" grid pattern on the other. If you want, send me your snail mail address, and I'll send you some to try. BOB
