FWIW:
I turned a shallow bowl and a smaller diameter, deeper bowl from the stock I had. Both items are beautiful--the grain patterns are unlike any other wood I've seen--and took a walnut oil finish well. But while turning the room filled with the finest cloud of persistent dust I've ever seen. It took almost an hour to clear after I left the room. Even with a respirator mask I still could smell the wood, telling me that some of the tiniest suspended particles got through the mask. Even though I was unable to find any references to toxicity, I doubt if I'd turn zircote again without some sort of whole-room air filtration system in operation. Any recommendations/experience on/with filter systems? Max |

Any recommendations/experience on/with filter systems? Max =============================== Max, I've had good results using a pleated paper filter on the input side of a window fan set directly behind the lathe. I use a 20 X 20 inch filter on the back side of a Lasko 20 inch window fan ($11.00 @ Walmart, filters from about $2.00 and up depending on quantity and quality, with electrostatic washable filters at the top of the heap). I usually run mine on the Medium setting (3 speed), which allows good flow, but not over heating the motor. Grainger has a similar fan in their catalog that flows 2100, 3200, and 4300 CFM when unrestricted. When it loads up, I take it outside and tap it to break the accumulation off, or clean it out with the shop vac using "blow" mode. To extend the life even more, tape or bungee one of the fiberglass filters on the input side of the paper filter to catch the larger particles and allow the paper unit to work on the smaller stuff. It may not be the ultimate dust extractor, but for $20.00, it's too cheap not to use. You won't believe the difference it makes. Ken Moon Webberville, TX |

I was looking into systems costing upwards of $150, so this is most appealing. Thanks, Max |

FWIW, I have a JDS air cleaner and it will clear the air of dust within a few minutes in my shop. Really make a difference. Peter Teubel Milford, MA http://www.revolutionary-turners.com |
