design idea - improved dust pipe

A quick bit of work with the saw and the design prototype has been improved.  It does give advantages over the dust mask as your lips create a seal around the tube so no dust can get in.  With nasal plugs you would avoid the risk of breathing in through the nose, but as discussed in the last post.  The draw backs are still the same.

design idea - dust pipe

I've been making a lot of models recently, but the disposable masks I wear to stop breathing in all the dust I create, never seem to properly fit (could be the masks or just the shape of my face).  The problem is designing something that fits properly around everyones nose and mouth.

Whilst pondering this problem, I came up with a dust pipe concept, like a smokers pipe with dust mask parts covering the intake.  Initial experiments prove that it is not ideal.  It works as long as you remember not to breath through your nose and it needs an inbuilt reservoir to collect all the drool you breath down the pipe.  Also shortening it so that it fits much closer to the face away from what your working on will help or an adaption to a divers snorkle? It's a work in progress!

Please consider the idea and not be distracted by my freaky monkey hand.
