Steve Chastain’s other books will be found in the Foundry section, but here he is covering the making of new pistons for old IC engines, be they from cars, stationary engines, or whatever - in other words he is talking about aluminium pistons, although much of the information applies to cast-iron ones. Described are the making of patterns and molds, then the machining operations to make sure you get the whole process right; if you don’t want to cast your own, then take the patterns to your local foundry. There is quite a lot of maths here as well, but at least you can now get that old engine fitted with new pistons. Great (and clear) information. 63 page softcover with many photos, drawings, charts and diagrams. Published by the author
