[TheForge] Home-made grinders and wire brushes (humor)

Thu Jun 23 11:48:36 EDT 2011

When I was younger and less knowledgeable, for a while, I was a house hubby.
So, when I wasn't tending the kids or cleaning the house, things like that, I was rebuilding a motorcycle in the living room.  I had a wire brush and a hand drill and cleaned that frame to a shine.  Of course I kept the kids in their room playing while I did that.

Now the problem arises is that I tend to walk the house barefoot or in socks.  The other problem was that the living room (where I did the work) had a shag carpet.

You get the idea.  I was pulling broken wires out of my feet for quite a while.

Painful lessons are good teachers.  Particularly when the pain is recurring<G>.

All the best.

There are wire wheels "potted" (thoroughly impregnated) with rubber.
I've seen these but never tried them.  In principal, they should be
less likely to throw wires, and slightly less likely to snag the work.

I'm wondering whether it might make sense to impregnate at least the
inner part of the wires in rubber like this to relieve to some extent
the stress they're under at the base, thus subjecting them to less
fatigue (from bending back and forth at the base) and, hence,
breakage.  Any thoughts?
