here's another one for putting holes in gaskets;

find a bolt a little larger than the hole you need.

put gasket on hard surface, like a smooth concrete floor or the flat part of your vice.

center the bolt over the spot you need the hole.

whack the bolt with a hammer.

if you look at most bolts, at the end of the threads it's usually indented a bit, so it'll cut right through the gasket and leave a perfect hole.

If you ever buy a futon at Walmart, they supply you with a double-sided wrench that's real thin like that. I opened up the smaller side a little (about 1/8" or so) and it's the perfect cone wrench. Wouldn't have gotten my coaster brake re-assembled without it.

Post An noob tip

My tip is if you have never put on an motor on an bicycle. To learn from the trials and tribulations that you people have went through , such as . cutting into an frame with an hack saw to clear room for the chain . And then the correct ways , of making holes in gaskets , and proper tools that I have thrown away , such as the wrench that comes with the futon , I will start saving everything I can . P.S I hope you people donít mind me following your threads around like an lost puppy for the sole popose of guinea pigs . I salute the volunteers of M/Bs America . For you all are the next super Dave's

This thread is awesome, i have to come back to read it all.

Whilst I'm here I should mention my tip if it already has not been said before.

Metal lined exhaust gaskets will fix all leaking exhaust gasket problems.

They are strong and don't blow out. They can handle vibration.

I used the standard one, it lasted a very short periods of time, blew out quickly. Must be from weight distribution and vibration from the engine.

So i tried the copper gaskets, thick ones, well they just leaked oil. they look good but will leak. tried exhaust sealant with it as well but that eventually failed.

Then I tried home made cutouts from exhaust material from the autobarn, it didn't work and just blew out at high speed.

Then i found the steel lined gaskets you find from Rock solid or other local country engine enthusiast dealer. And it worked a treat. I am still using it. and it has been months now, so if anyone has an exhaust gasket issue and need to change it constantly, get a metal lined one.

Making gaskets,
My wife pointed out that the craft store(larger chain stores) have a leather "dressing kit, comes with many different size hole cutters as well as decorative dies, which when tapped with a rawhide mallard, would easily go thru gasket material, plus you'll have 'em if one decided to do some leather work/seat cover etc. The kit I saw was $29.00. they have some bugger ones and some smaller too, some even with a burning tool. Just a thought.
