Thanks Fflintstone. When you pick them up they are as loose as a goose. They want to go in all directions at once. But when we hit a rock while mowing with our mule mower they were worth their weight in gold.
Fliffy42 I don't know of one but it sure would be a handy dandy tool.
Aunt Phil I have a small grinder that I've not started restoring yet that you bicycle to run the grind wheel. I'll post pics tomorrow.
