Workshop Dust Study - Video

[Stone Message]

Hello Everyone

I hope that I am posting this in the right place...

After developing some minor problems as a result of workshop dust I wanted to find a way to explain the main issues without too much technical stuff. I have done all sorts of tests in a fairly limited time (as the dust measuring gadget was on loan for a very short time) and I have put it all together.

The bottom line is that Festool kit does really well but whatever you do you must invest in good quality extractors and at some point everyone should invest in a powered respirator or good quality dust mask.

Here is the link:

Very well done.
Thanks  for sharing.

Good on you Dusty ... ooops, I mean Peter  [wink]

I will do more about dust later in the year. I have been reading some technical detail about MDF. The key worry is Formaldehyde but not all MDF has that inside. In the UK there appears to be no quality assurance scheme to tell you what the particular sheet of MDF contains; I do not know about the rest of the world.

I will try and borrow a machine that measures the amount of Formaldehyde in dust and see what figures I get with different types of MDF.

I also want to look at dust particles in the really nasty sub one micron level.

I may also do some dust level tests with some more machines although I doubt whether it will be easy to borrow machines as I suspect that manufacturers are very wary about having their kit openly tested. I would like to test more Festool kit in order to inform the green community - so far it looks pretty good.

I learned a long time ago not to assume anything, Peter have you read Bill Pentz's dissertation on dust, dust control and collection. If you haven't its a long read but you might find some useful info.

Thanks John. I first started reading Bill's stuff when I was considering making a cyclone - luckily I discovered Cyclone Central.

I wanted to make a simple guide, backed up by a tiny bit of science (the measuring gadget) and looking at real life figures from workshop tools. My overall aim was to get a simple message across.

Thank you so much Peter; very informational.
Truly appreciate your professionalism and research on this.  Very important.

I'll second that; thanks for doing this research Peter!

I  see Axminster  in the UK now stock  the Jet DC 1100A.
This is the unit  with the vortex  design  and  the  cannistor  capable of  stopping 1 micron.

I think my  electra beckum  stops  30 micron.

Though  atmospheric  dust is going to collect on the outside  of the filter bag  anyway  resulting    in the dust cloud  on start up.
I'm going to upgrade my eb just as soon as I have the shekels saved up.

I'm curious if anyone has done any long term studies on dust exposure.  My grandfather, whom I learned how to work with wood, has some pretty nasty health issues now related to "nerves".  They don't know anything really.  I live in the states where pills are prescribed for anything and everything, even though they can't say whats actually wrong with him.  Anyways,  he has a relatively small shop, maybe 15'x40' with 8' tall ceilings and he has never had dust extraction.  Most of the work that he does creates loads of dust: Table saw, lathe(lots of lathe) , jointer, planer, band saw, miter saw, router, sanders and hand sanding.

If anyone has heard of any type of study, please post some links.

Thank you Peter.

Not only does one need to worry about the dust particles but also the material producing the dust. Some material like asbestos has a well documented health risk. But most forget that some of the exotic woods or hardwoods can also be toxic, Wood Toxicity Information Wood Allergies and Toxicity.

Also the glues can contain various irritants and toxic chemicals.

Do not forget treated outside lumber and its dust. Some use Copper Cyanide as the anti-insecticide.

It is always a good idea to wear a hat and wash your hands before touching your mouth or nose and before you eat and keep a lid on your coffe cup.
