Part of the day job at present is overhauling a Crossley BW1, 1940's
4-stroke single cylinder diesel, 5" bore with a wet liner.I've hit a snag in that the liner should project by 2 to 8 thou above the block face , to ensure the gasket is properly compressed. Tried the new liner in place today, it is dead flush. I need to make a shim/joint to bring it up a few thou, snag is of course the liner flange is only about 1/8" wide. Whatever I make will have to be neat & pretty accurately to size. The book does rather ambiguously make passing refernce to a 'special joint' here, I don't think Crossleys will have any on the shelf :-( If I can find some suitable copper or steel sheet, how best to do it? I've got a trepanning tool & so on, but cutting something that thin & narrow is going to be tricky even sandwiched between other materials. Wondered about double-sided tape & a very sharp knife tool, but the d/s tape I have is far too strong to stand much chance of releasing something that flimsy in one piece. I've seriously wondered about some sort of metallic epoxy under the liner flange, skimmed off in the lathe to leave just a few thou.
Suggestions?
Incidentally, the book refers to a nickel-asbestos gasket for use when cooling with salt water. I've never come across that before. 'fraid we only have c/a joints in the stores
