You've encouraged me.
See what I can scrounge up at the local junkyard and go at er with the trusty dremmel.
I do remember trying to grind at a cooling head awhile back and the aluminum kept gumming up the grinding stone or sanding drum.
Should I be using carbide tips or something? There's gotta be something that works better and isn't a cutting disc...I'll google it.
Danke-
