In reference to the dust collector discussion in this thread about the 12V motor, http://www.bessex.com/forum/showthread.p...28#pid4428, here's what I conjured up to deal with the dust problem with my Kally.
It uses the little Harbor Freight dust collector which motivates 660 CFM air flow through a 4" tube. There is nothing else connected, so the 660 CFM provides good air flow/suction at the base of the Kally. It's inexpensive at $159, and since it's HF a 20% off coupon can almost always be found so they can be had for as little as $125.00.
It's been a good little unit. Knowing HF, I went over it carefully when I got it. There were a lot of loose screws and it was sloppily assembled, so I checked and tightened everything and it's been a trooper now for years.

Here it is on my Kally:
To make a diffuser, I cobbled together a bucket, some PVC adapters and some dryer vent hose/pipe. The input/output pipes extend down about about 3" above the bottom of the bucket. A plastic divider goes between the input/output pipes extending from the bottom of the bucket to a couple of inches from the top. This causes air flow to start at the bottom, go up over the top of the divider and down again to the bottom of the bucket before proceeding out the output pipe, providing for a lot of air flow for sparks to cool in before exiting the diffuser bucket.
When grinding something that produces sparks, I just put a couple of inches of water into the bucket. The extended input pipe blasts the air directly at the surface of the water.
Here's what the inside of the diffuser bucket looks like. Arrows indicate air flow direction.
