Just got myself a used 1/2 HP baldor grinder. It has openings in the
back of the wheel guards, for dust collector or some such. I am
thinking about attaching a shop vac to these openings. Is this plan
fatally flawed, or is it workable?

Nothing wrong with the idea, but be advised that if the vacuum is used for
collecting combustible materials, saw dust, for example, you'll eventually
set it on fire with sparks from grinding steel. Use caution unless it's
a dedicated collector, strictly for your grinder.

Put the vac a distance away, for the noise abatement.
Make the intake of thinwall tubing. Run it into a 5-gallon bucket with a
n air-tight lid, with the end of the tub about 3 inches from the bottom.
Fill 3/4-full of water. Attach vac hose to the lid so it pull air from
atop the water.
This way any sparks will wind up in the water, the water will filter the
air enroute to the vac.

Keep the water level up, as it will evaporate.
Be sure the vac is wet-or-dry.
