I like it. Perhaps some stripes of Vaseline would catch the particles
and better show the distribution of the spray.

Hi Ned,

I am an applications engineer and have been working for a variety of
dust collector manufacturers for over 15 years. The best way to
handle a small surface grinder is to incorporate the splash guard into
a box like hood with sides and a roof. The roof would be your pick up
hood or suction hood where you would mount a collar to attach a hose
that you can run back to your collector. What is the width of the
table, this will determine your hose size?

The other method is a magnetic hood that can be attached to your wheel
guard, this hood is closer to the source and can be used for dressing
the wheel. Sometimes tolerances are critical on machines and the
added weight will effect of the hood will effect the part tolerance.

I currently work for a small dust or mist collector manufacturer and
we can offer a collector depending on if you are filtering mist or
dust or both? The company name is AER Control Systems, visit our
products on the web at www.aercontrolsystems.com. If you would like
to phone me, I can be reached at 866-265-2372 and we can discuss.
