You can use heavy shopping bag paper from the grocery store (aka Kraft paper). After you cut it to shape, wet it with steam oil for use. You can buy small punches from the big craft stores to cut holes for fasteners. The gauge 1 crowd is fond of cutting up dollar bills but the grocery bags work fine. Fold the sheet twice to make it quarter size and then it is simple to cut the center rectangle of the valve chest. Technically you want a strong, long fiber paper.
For the main steam dome and backhead go to the auto parts store and buy real gasket material. I have a sheet of FEL-PRO KARROPAK that is about 0.014" thick and it is good quality treated paper. You can buy thicker sheets (1/32 and 1/16 of gasket material if you want.

Hi Ed and all,
Any high quality paper is good. The reason dollar bills started to be used in the G1 crowd is it is actually cheaper to make gaskets from $1 bills than order them from Aster.
We used a lot of old navigation charts for gaskets on the ships as the paper is high quality.
I use a high end linen writing paper for my gaskets. This can be stuck on with silicone as the temperature range for model work does not exceed the ratings for silicone

Hey you guys, I just discovered Global Express and Priority Mail envelopes ( free from PO ) that make nice gasket material. I went to this because the "auto store" gasket material kept breaking on the narrow sections on steam chests when I punched the holes. This stuff will not break. I use it with a little RTV and live is better. I'm still a novice so if any of you more experienced guys have a comment on this let us all know.

I forgot to mention that this envelope material seems to be made of a random weave material like Kevlar, it's impossible to tear.

Well it is probably too late now to mention this, but the paper covers that come with 5.25" Computer Floppy disks are also near impossible to tear and probably would make for great gasket material.  |

Oh lord I remember that stuff. I'm pretty sure it's Tyvek or a variant thereof. You can by tyvek as mailing envelopes as well. I had a bunch of the stuff for mailing out calendars at one point. You'll be hard pressed to find it in the floppy disk cover form these days |
