Folks -

Okay, the router wasn't stout enough to draw the plate down flat, so I put a
couple of threaded inserts in the table and pulled it down flat... I know,
not as clean as I'd like, but I've got some edges to profile tonight.

I got to thinking about chips falling/being sucked into the inverted router
motor and got to thinking. Rather than a shield that just clears the arbor
nuts and keeps debris out, what about a thin piece of plastic (think milk
jug) that pushes onto the shank of the bit, spinning along with it and
throwing debris clear of the motor vents? What gave me the idea was the big
"washers" for lack of a better term, that you would find behind an oil seal
on a crankshaft or pinion shaft... They throw the bulk of the oil away from
the seal and seal lip so that it doesn't have as much to contend with...

If I cut the flexible plastic round and had it centered, I don't see that
balance could be affected. Whatcha all thimk?

PS: I will NOT be mounting a wire wheel on the router, in case any of you
smarty-pants type were going to chime in.



On the routers that I've looked at, the internal cooling fan is
designed to exhaust through the opening at the shaft end of the motor,
in other words, whatever air the tiny fan pulls through is exhausted
in such a way that it helps blow chips & dust away from the insides of
the motor. Aside from spinning a piece of plastic at 23000 RPM you
might also cause the router motor to overheat.
