Know what a "PMA" (part manufacture authorization) is? I'll bet you your next paycheck there was no paperwork that came with those things. Even if they were for an Experimental Category airplane (read 'homebuilt'), they are too amateurish to be taken seriously, let alone installed. Best ad...

Thanks, Alexa.

Helpful stuff.

Looking for advice on buying a dedicated wheel for my 8" grinder to be used for tungstens only.

Was thinking of a white stone, maybe 120 grit or finer.

What do y'all suggest?

Thanks in advance.
