    Trimble's method works very well. The jigs and fixtures are a bit of trouble to make up, but the results are worth it. I used commercial cast iron stock from one of the hobbyist suppliers to make a set of eight rings for a four cylinder engine. I have heard that cast iron pipe fittings are made from a good grade of material and should be suitable for rings. A furnace and some anti-scale compound is handy for heat treating the rings, but isn't absolutely
    necessary.

    Friend of mine claims, during WWll, he made many piston rings for automobiles from sewer pipe, and fittings. Might be worth a look, Never even chucked a sewer pipe up myself.

    Piston rings

    Has anybody used George Trimble's method of making piston rings that's descried in "Strictly I.C." magazine #s 7, 8, and 9? If so, do you have any words of wisdom for somebody who's about to try it?

    Will ordinary gray cast iron work, or do you need to use the high-grade cast iron he describes?
