Gasket Trick

[Phil Waterman]

I’ve just started reassembly of drive train components for my `41 C60L Pattern 12, this is a total disassembly restoration. The problem how to replace all those paper gaskets in the transfer case, old method trace and cut out. New method scan the various parts on flat bed scanner and then print them on gasket material.

Took some playing around to not have the scanner distort the image and to keep size in all dimensions. Solved the slight ovaling caused by the scanner movement by increasing the resolution to 600 dpi. Also, put a small machines ruler in the edge of each scan for quick check of dimensioning. Used the sketch feature of graphics program to produce outline of gasket, thus reducing the file size.

Another trick to cut all the bolt holes as to take some tubing of the correct sizes sharpened the end of the tubes. Then chucked desired size up in drill press set to high speed cuts very neat holes

I’ve saved all the gaskets and will be posting them on my web page.

interesting and ingenuous method, but why not do it the old tried and tested way with a sheet of gasket paper and a small engineers hammer ?, it's a lot quicker and probably more accurate

Hi Peter

Yes, for some of the gasket the traditional way works well. For some of the housings with lips and studs it is hard to imprint them that way. The other advantage is that I have if I muff cutting out a gasket or punching a bolt hole it is no big deal.

One off gasket I'd use the traditional but were multiple gaskets are needed this method works well. Right now I’ve got several transfer cases to over haul and replace all of the seals. Next step is to see if the images can be fed into the cutting unit they use to make vinyl signs.

Cheers

I'd go with Pete although I see some useful specific applications in using new technology.

There is something deeply satisfying about holding the gasket paper down and tapping round a casting outline with your small ball-pein hammer to have a perfect gasket suddenly materialise.

Or is it just me?

Is this the same as a ball pein hammer? This is what I use to make gaskets.

I hate to agree with a Pom but I have to agree with a Pom! Making a new gasket with a ball pein is very satisfying.
