Had another wee set back yesterday and today. Had a small fire start in my dust collector. Seems that belt fuzz, sparks, and plastic don't play well together. I got a HUGE hole burnt through the plastic pick-up hood behind the grinder, an 8" section of flex-hose burnt through, and the bench got scorched as well. This happened when the Blaze 60x belt fuzz piled up in the intake and ignited and was fanned on by the rushing air. I smelled the burning plastic, stopped to see what was burning, started tearing the system down and before I could figure it out the damage was done.
Today I removed the grinder from the bench, fabbed a new stainless intake bucket, and added stainless tubing down to the sucker. I'm not sure if this is enough though since the real problem exists from the belt fuzz. If I ground vertical I would just shoot it into a bucket of water but since I grind horizontal this isn't as easy an option. If it persists I'll just have to figure out a way to blast it downward into a bucket.
