Grinder dust collecting

>There is a lot of junk that comes off the grinder. Wheel dust, metal dust, Sparks. Do most of you run this stuff through your dust collection system? I�m wondering if the metal dust is a problem for the dust collection motor or any other possible problems, sparks-Dust???

>We have gone 'round and 'round on this subject before. Generally most of us agreed that a grinder spark would not still be glowing after going though the DC air stream. But we also agreed that it probably was not worth the risk. You might want to try a small cheap shop vac.

Don`t do it!

>Using your WWing DC for collection of grinding dust is asking for a fire at best.
I generally contain it as much as possible at the source and then use the shop vac after I`m done and everything`s cooled off.
The industrial collection systems I`ve seen and used were all metal construction.Even the filter plates were metal mesh.

After thinking about it hard I've decided to run metal pipes from the dust chutes down to a metal bucket. I haven't decided how to do the fan yet. I was going to put a fan on the bottom to pull the debris down but that will just ruin the fan. I'm thinking about putting a fan on the top blowing down but I'm not sure this will create enough "vacuum" to pull the dust in.
Either way I'm going to go proactive about collectin the dust from the grinder. Anyone have any ideas? A small squirel cage fan on the bottom might work since the motor would be outside the pipe and less prone to abrasive dust damage.

>Bob,
I should have been clearer in my suggestion. I was suggesting a plastic shop vac - dedicated to the grinder, so that there would be not combustibles inside.

>I seem to recall seeing a solution to this problem that consisted of pipes connected to the back of the wheel guards of the grinder. The pipes went into a bucket partly filled with water, with the ends of the pipes submerged in the water. The top of the bucket was closed, but had a pipe to the dust collector attached to it. You turn on the DC and the air is drawn from the grinder wheel guards and bubbles into the water, depositing the detritus.
I have no idea how well this would work, but it sounds plausible to me, if you can modulate the air pressure.
The hookah solution.
