[TheForge] Abrasives for Stainless

[Woolley]

Greetings

Can you tell I'm on a mission to make my life with stainless easier?  I
need to blend my welded areas to the rest of my #3\4 finish stainless
tube steel.  I'm going to use a 4750rpm strait grinder with sewn cotton
buffing wheels the edge of which are coated with glue then dipped in 80
grit alumunum oxide.  Does anyone use this setup for grinding\blending? 
I'm fairly clueless as to what glue to use etc.  Is brown aluminum oxide
blast media the way to go?  Since I'm in the info gathering stage, any
help is greatly appreciated.  I already bought a Suhner variable speed
(2500-5500 RPM) strait grinder, so that much is covered.

Regards,
Bill Woolley
