    you wont make the shims any thinner Bill.

    they are extremely hard to take the punishment they get.

    i even tried a sheets of shim steel in various thicknesses but that didnt work and the thinnest shims simply worked their way out.

    you can buy a selection from ebay for about £3 for 10. I personally prefer to run the engine a short while before shimming tappets, but according to the manuals you arent supposed to need to, plus you need to be sure you have some clearances first. When you get the selection pack, you shuffle round between the ones you have and the new ones till you get the right sizes. Tolerances for your engine need to be looked up.
