"machine" some out of oak to the correct tolerances. some posters here
also soak them in WD40 but I haven't found a need to do that. sometimes
I use PAM on the the blade but only if I am cutting green stock. I use
them for all my blades, from 1/8 to 3/4.

Yea, I've heard of that. Was trying to avoid the machine work.
The time is worth more than the $10 Cool Blocks cost, but then again,
maybe not - if they fit like these do... these things suck!
Thanks,
