Iggie's post is a great example of the benefits of running tools at the

Yes? Really? Usefull? And how do I calculate the surface speed? Do I need
the diameter of the brush?
It was just another of those empty Iggy-postings. Nothing, *absolutely*
nothing to learn from.

You can't calculate surface-feet/minute? One thing learned from I's post is
to listen to Tommy about brushes! There ARE better experts in the world,
about six of them.



Nick could calculate the surface speed by multiplying diameter of the
wheel by revolutions per second, and by pi. The diameter of the brush
was given (8 inches).
