replacing muffler gasket?
Moving a TTpro .36 into a new bird and The muffler gasket has a tear in it..
Can I create a new gasket out of something or do I need to order one? or reuse the old one with the tear in it?
Thanks
Steve

RE: replacing muffler gasket?
Many engines are machined so well, they don't even need a gasket. Try yours without it and find out. If indeed you do need a gasket, use ATV silicone from your local car parts dealer (Auto Zone, etc.).

RE: replacing muffler gasket?
I ripped a mufler gasket recently and my local LHS didn't stock it, so I cleaned up the muffler with alcohol and pressed the mating surface into an ink pad, then I stamped a heavy sheet of paper about a dozen times with the mating surface imprint. A few minutes later, using a fairly new blade in a razor knife, I easily cut a nice paper gasket out and put the remaining paper in my engine file, so I had more gaskets ready to cut out for the future. Even the bolt holes are easy to cut with a razor knife.
This whole process took less than 15 minutes and did not involve gluing the muffler on with RTV, dealing with the ooze on the outside and potentially on the inside of the engine, hindering the exhasut flow to the muffler.
I used to cut 90% of my own gaskets for my old British cars and motorcycles, when they were hard to get or I couldn't afford to buy them. Now, it's just easier, faster and every bit as good.

IF your LHS carries the replacement gaskets they are probably cheaper than a tube of RTV.
The last gaskets I bought where about $1.50 and came 3 to a pack.

I have done the same, using a manila folder as gasket material; with excellent results.
I copy the track by putting the board over the surface previously oiled (not much, just wet).
I made the holes by punching with a brass tube over wood.
Even better results are possible by soaking the gasket in castor oil before installation, and re-tighten the bolts after a couple of flights.
If taking the silicone route, use the red staff for high temperature.
Regards!

This also works very well : http://www3.towerhobbies.com/cgi-bin...&I=LXDF10&P=ML
There is enough in there to make several gaskets.

I use old V8 cylinder head gaskets. They'll give them away at an auto shop because they discard them anyway. If you get one, it will last all of your life. They're big and you can cut the needed shapes with exacto blades.

I also use nothing. However I also take a piece of glass and some 400 grit emory paper and flush up both surfaces. Just lay the paper on the glass and with some light oil work the header back and forth. With the engine off the plane.The glass/paper can be slide to the edge of the work table and worked over the same way. Just be sure to pack the exhaust port with paper towels before you do it. On most engines the holes the bolts pass through are high.

Gasket sealer.
It has a 1000 and 1 uses on the hobby bench including perfectly made wing seats, sealant for firewall holes around throttle cables etc.
