Safety reminder

[rasret01]

For those of you who use the excellant tip of placing a furnace filter covered box fan to catch dust behind your grinder... please remember that the filter is paper and the sparks are hot! (Ya, ya, I found out the hard way) No real damage done, but the scary part is that the filter didn't start burning until after I had turned it and the grinder off and walked away.

Be Safe.

That really is one of the dumber ideas I have heard recently! Glad nobody was hurt.

I have never heard of anyone putting these behind the grinder. They are marginally effective at scrubbing air but are only as good as the filter you put on them. Most filters won't trap much of the very fine dust which should be our biggest concern. A HEPA filter is what is called for and they are not cheap.
This setup should not be used to collect dust right off the grinder, it is a substitute for a re-circulating air cleaner/scrubber, not a dust collector.

Box fan/filter or not, it's important to at least vacuum behind/under the grinder daily, preferably around the whole work area. A $40 shop vac and a few seconds a day can prevent a lot of problems later.
