[TheForge] Re: wire brush

[Peter Fels And Phoebe Palmer]

The thing about cup brushes is that they are a waste of $ at 
higher RPMs. When the revs are cranked up,the wires are thrown 
out sideways and lie flat in the cup.
Because only the very tips of the wires do the cutting, you might 
as well use a cheaper,flat disk  wire brush., unless you have a 
peanut grinder with a speed control.
I have an article on the subject coming up in one of the ABANA 
publications in the not to distant future..i think..
