Hello all, I need a backplate gasket for a Max-S 30. What is the best material to use and where can I get it. Also what thickness do I need? If anyone knows where I can get said gasket this info would also be appreciated.
TIA,
Rich

You can easily make your own using Bond Paper( this is the kind which business letters are usually printed on). Simply measure the diameter of the hole in the block, divide by 2 to establish the radius of the hole you'll scribe with your compass, cut it out with either a #10 blade or a scissors, poke holes through your blank after you push the back plate through the big hole, and bolt it tight with your BP screws. Cut the excess off with your knife and fly! The paper is amazingly durable and with the good quality of junk mail paper we get daily you'll have a never ending supply! This process works on all the engines I've ever used over the past 69 years. You may use an all, or a compass' pointy post to make the holes in your blank.

Rich? you have some of the best parts supplier right here. Just ask one of us and we will probably have what you need. Send me a pm with your address I believe I have a few. Take care, Ken

I use Fel-Pro 1/64th "Karropak" from local Auto Zone... $3.00 for a sheet that is 12"x36"... I never use a compass... I lay the BP on cut out square and trace with a fine pen or sharp pencil... then cut out the hole with a #11 Xacto... keep the material dry, it is easier to cut that way... then I put the matrieral I just cut out over the BP for fit, install on the engine, then I use an awl to poke the first hole... then oil the first bolt with light machine oil and screw it in to keep the gasket from moving ...poke any other hole next and install the bolt... do the other two... I use oil on the bolts as it helps break down the gasket material that is in the hole... I cinch everything up lightly, don't snug them up yet... then I use a new #11 to trim the gasket over hang... once this is done. I put a little tiny bit of oil on the new gasket in the crack, you may want to unscrew the bolts one turn... cinch everything up and you are good to go..

Rich,
I do it the same way James C. does it except I use a grocery bag. Cheap! Bags used to be free but now I have to pay a quarter for a bag..........Still cheap considering that I probably could get 100 or so out of it! LL~
Cheers, Jerry
PS: I use a No. 11 exacto blade.

Hi Rich:
In the past, I have ued gasket material that comes in a squeeze tube ala toothpaste. This stuff has worked very well for me on engines of all sizes.
There is a new anerobic (sp) stuff that is sold at the local auto parts store that works very much better then the older stuff. I think that I would give this stuff a chance as it may be easier than cutting a gasket.
Good luck,

Be a bit careful running with just goop as your sealer, some engines rely on the thickness of the gasket to give the correct clearance.
Can't remember which ones though! :P

No, I didn't, and it's pretty amazing!

I use photocopy paper, brown business envelopes or playing cards, depending on the thickness required.
For the paper ones you can use a pair of dividers and then the no. 11 blade, or just hold the stock securely over the crankcase and run the blade around to cut out the centre.
Then put the backplate in and with a piece of sharpened 1/8 brass tube mark the screw holes. Remove the gasket and punch out the screw holes.
Give the gasket a light coat of oil and reassemble and tighten up the screws. Trim off the excess from around the backplate and go fly.

I do much like Greg A. but i bought a roll of 1/64th and a box of 1/32nd a long time ago. One of these sizes always seems to work. The 1/64th usually good for back plates.

Playing cards and Manila folders work well also...
Since they are available, I would go for Randy's offer.
