[TheForge] Making power hammers

Fri Nov 29 19:09:00 2002

I use cap screws with lock washers, they never come undone, then when I
forget or lose the washers they also never come undone :)
I used UHMW and its great its all Ive ever used so Ive nothing to compare
but it is designed to handle this type of use.
