Wow,

Kind of painful finding out I'm an idiot.  Well, I'm more or less vaguely
aware of it at times, but to have it pointed out publicly when least
expecting it rather smarts.  Seems like whenever I mention my private way of
doing things to this forum I get a bracing splash of contradictory
information.  It can be hard to rouse the sleeping ignorant, but I am here
to and wake up and learn!

But what great dreams I was having that I was running a large blade on a
powerful light grinder.  The blade was flashing naked in the open sunlight
and that nasty 9-inch grinder had been put up on a dusty shelf.  Even as I
sit in the hospital with one eye removed and metal shards embedded in my
brain, I shall never forget the sweetness of that dream?nor shall I stop
cursing the day I came to believe in it.   Back to sleep, perchance to
dream?

Part of the point of of the variable speed grinder with the oversized blade
is that the grinder can run slower to run the faster moving larger
circumference at a safe speed.  I have rigged the safety guard from the 9-
inch to fit on the 4.5, so the larger wheel can be run safely. But
admittedly that was only to rig a water line and act as a splashguard.
(should I be chastened for using water as well?)  Why I do not always use
the guard, beside that fact that I have a waterline rigged on it, or that I
am always switching to sanding or brushing applications, I do not know.   I
didn't know people even used them.     I am not using a segmented rim.  I do
not have a tiny fraction of the knowledge that Simon does.  My only school
has been to audit a marble symposium where as best as I can remember
instructors pointed out that grinders were obviously dangerous, but only in
a cutting way, not an exploding way, and that really no one used the guards
as they got in the way.  Then I watched throughout the session as everyone
 from beginners to a sculptor of international reputation mounted up blades
without guards.

Are sintered rims dangerous but electroplated ones safe? Flush mounts.   Are
they to be avoided?

I will certainly give using the guard another try.

Simon, I fear you may catch me sleeping, but thank you!
