I have a '28 Farmall Regular which has steel pistons. If I can ever get the dammed things out I'll take a picture.Do you remember the way Jim Cathey removed the pistons from that rusty Hercules generator?
But they were aluminum pistons, and were untouched by the corrosion. So I was ahead by half right there. Electrolysis would be an easy thing to try first, it's nearly free and only takes a little bit of time and electricity. -- Jim
