Homemade Gaskets ???

Homemade Gaskets ???
I have a couple of old Enya engines I'm dinkin around with. All the gaskets are toast or completly gone. I'm not even going to waste my time looking for obscure parts like this. These engines are both 70's vintage. I'm looking for suggestions for materials (easy to find,common ect.) for use in cutting my own gaskets, both the paper and copper. Any help is appreciated as alwayse.

I used some thin brass sheet from the LHS I can't remember the brand name, but its on a little display rack with tubing, etc. You can cut it with scissors or a sharp exacto and it seems to work well on the bigger engines I used it on.

I simply use file folder cardboard and make the inner hole for the backplate with a round hammer tapping lightly in the edges, then the screw holes with the point of a round tip allen key. I do all this in the engine taking care not to move the card board. Then install the back plate and cut the excess card with an X-acto knife.
Works really well.
It´s hard to find replacement gaskets in Mexico.

Auto parts stores have sheets of various types of gasket material.
Here is a circle cutter I use for gaskets. A hole punch takes care of the screw holes.
It fits in the chuck of a drill press.

a backplate type gasket can be made from a playing card!!

The better auto parts houses will also carry brass shim stock in various thickness -- can be had in very thin stock, sometimes in increments of .005"

I just go to the local auto shop and get sheets of gasket material. I got this one pack that comes with a sheet of cork, some special paper, and two thicknesses of gasket material. Really handy, and they last a while too!

Jess,
I got mine from a guy who had a booth at a model airplane contest. It cost $5.00.
The brand name is "MORN."
If you find one, set up your drill press for slow speed and cut lightly.
Pin down your gasket material so it cannot shift. Cut the inner hole first, working out to the outer hole as the final cut.
There are spare blades in a compartment on the back of the circle cutter.

Back when, I found the Enya gaskets to be about .006" thick. Could not find that thickness of material, but did find .005" to cut from at the big cost of $1 per running foot. The head gaskets measure out to be about .003" each.
If you substitute thicker materials, such as a playing card of about .014" to .016", then you will be reducing the crankcase compression a bit and thus not permitting a full hard charge of fuel/air to get up to the combustion chamber. Considering you may have a bit of leakage out the crankshaft bearings already, I would think it best to maintain as small as crankcase volume as possible. With a low crankcase pressure, the engine may tend to only want to run in a rich condition, and not rev up to where it was in the older days.

For thin gaskets, I use a dollar bill. U. S. paper money is the strongest paper I have found. If the gasket is small enough like Cox .049 or .020 tank gasket, then I clip off the corner of a fairly new bill. Put it against the crankcase & poke a hole for the pack plate screw. I then use short screws to hold the gasket to the crankcase and use a new or really sharp Xacto #11 blade to cut the crankcase hole. Trim the outside edges and gasket is done. It is extremely strong and fuel does not seem to weaken it.
Good Luck

Here's my feedback, I cut my head gaskets w/ cutile sisors and used a playing card for the case gasket. I used the Joker, is that going to be strong enough? HA. Thanks to all who responded for there great advice. I took the old Enya out to the test stand and once I got the needle figured out ( 1-1/4 turns is rich, wow) I can start the thing on a couple of flips. I don't have a starter that can turn a .19. Man this thing is LOUD though. It idles great, so low I think its going to die, and has good transition to full throttle. I'm putting it in a 47" spacewalker I'm working on. We will see how it turns out.
