[modeleng] Re: Dust from hard woods-workshop projects

As an emphysema sufferer, caused primarily through inhaling wood dust during my 
time as a wheelwright and carriage builder, I would urge the utmost precautions 
are taken when working with wood in situations that can cause dust. Vacuuming 
afterwards is no good, the fine dust is what causes the problems, and that 
usually can't be seen. Dust extraction  during work is the only way. I'm sure 
that ingenious chaps such as we all are on this list, can jury rig a vac 
cleaner to sanders etc. I now use flexible plastic conduit piping from my 
sander to a vac several feet outside my shed. It's light and doesn't offer much 
drag when working, though the corrugations do make a bit of a whistle.

  Subject: [modeleng] Dust from hard woods-workshop projects

  Hi to all,
  I am told that most hard woods that we work that  produce dust are bad for 
us, i surpose when woodworking was done at slower speeds with shavings instead 
as now with routers at high spindle speeds.
  I surpose that metal machining  that we do at work with very high spindle 
speeds and large feed rates(15,000 to 30,000RPM) and flooded with 
coolant/cutting lubricants we get a mist which we need special 
collectors/Vacumn cleaners so that the workshop does not end up in a haze.
  I would think that with Health and Safety that this has been looked into and 
we are protected againist harm(I hope).
  Not the kind of thing that we encounter in our home workshops except for 
wood, and a vacumn can take care of that.
  On another subject what is everyone making at the moment in their workshops.
  yours for now.
