    Well hello to all I’m shore this has been asked but hear I go agan ? So I’m doing the Hodgson 9 for a start and thinking gaskets! O wonderful things in full size but my question is what do you very clever lads use ? Problem is I need very thin my brain wave tonight was ( as I was cooking dinner) bakeing paper ! Lol I got out the old 0 to 25 mm and it’s only .04 mm thick ( very nice ) and should be ok with oil and quiet a bit of heat .

    Ok so am I nuts has anyone had the same thourt with success?
    I will be very interested in any reply

    I use teflon sheet. Teflon holds up great and if you ever need to dis-assemble it will wipe right off and be ready to re-install. I use .020 thick for head gaskets and .010 thick for everything else.

    BTW, about 3 weeks ago I started making parts for the same engine.

    I get mine off ebay here in Aus. If you can't find it here try searching in metric instead. I think I buy 0.3mm from memory but it's been a while.

    I have successfully used a greaseproof/baking sheet paper head gasket but I have not run the engine for any prolonged period. Both the mating surfaces were lapped flat. I stripped it down after an hours running and there was no sign of any burning out. The cylinder head does have a water path through it.

    I was thinking of making my head gasket out of copper chimney flashing. Does this sound as if it would work?

    Hi joump5
    I wasn’t thinking head gaskets more so for frount cover and under cylinders
    As for the head gaskets the copper should be ok but I have seen soft ally flashing about 1 mm thick
    Would the copper be a problem as far as corrosion???
    I would look for the ally flashing I think

    I think the baking sheet paper would work admirably for anything other than cylinder head. Most of my bike engine gaskets were paper.

    I have only used printer/photocopy paper, cut it out, soak it in oil. Used it in steam engines, flame lickers and IC. Yes head gaskets too, it does not burn away.
