Micro-Mark Desktop Dust Collection System

[eurekapaul]

In my garage woodshed, I'm pretty careful to collect and minimally breathe dust. However, I'm not as careful in the shipyard, although I run a small HEPA filter.

 

To the end of keeping my lungs working well, I'm considering buying the Micro-Mark Desktop Dust Collection System.

 

If anyone has used it, what do you think? In particular I'm interested in how well it works and how much noise it makes. Also if anybody has any opinions on it, please feel free to express them.

 

Thanks,

 

Paul

I spent some years designing dust and fume collection systems for laboratories and research facilities. Most devices like this are of little value; it’s the nature of the beast.
Try this experiment:  Get your vacuum cleaner hose, and hold your hand a 1/4” from the nozzle. Feel the air movement?  Ok, now move your hand 1” from the nozzle:  you probably can’t feel air moving, or just barely. 2” away you feel nothing. 
Now, connect your vacuum hose to the discharge of the vacuum ( if you can). You can hold your hand several feet from the discharge and still feel the air movement. 

Why the difference?  Air best flows to where it is pushed, not pulled. 

The suction of the hose is relying on barometric pressure to push the air into it ( essentially, the vacuum hose creates a “ hole” in the surrounding area near the nozzle that the air “falls” into). On the discharge end, the energy from the vacuum cleaner motor has been imparted to the air and will move with more force. 
To better control the particles in the air, get a small fan to blow across your work surface away from you.

Steve,  I use a small USB fan for that purpose.  The dust settles in a corner of my shop, and I vacuum it up.

 

l was a little put off by the price of the MicroMark device, but really couldn’t comment from experience.

 

Your information is very useful.

I bought this (or something similar) years ago when I was going to get into carving:

I haven't used it yet to be honest as I haven't been doing any carving, so not sure how effective it is.  It wasn't exceedingly loud if I remember correctly.  When I do things like sand or drill or work with resin, I found putting my shop vac nozzle in a vise near where I'm working is an easier and very effective method for removing dust.

I wear a dust mask and use a shop vac, it is a little loud but i can direct the nozzle at the location or tool I'm using and it collects most of the dust. I have a clamp that i mounted to a board that holds the hose nozzle in position. I wear ear muff style noise protection.

if you are using it for when you run tools... your shop vac is the perfect dust collection system... youll have to make adapters for each machine.

No way would I pay that much for a machine like that.  I would question its ability to move enough air to do the job.

 

For in the house - at the bench - I use a Kenmore Blue Magic small canister vac.  It uses a collection bag - which is a pain, but otherwise does the job.

 

The handle at the end of the hose has the ON-OFF - which is a slide power control.

I attached the handle to the end of a desk lamp  arm (less the bulb part) using cable ties.

There are desk lamps and THERE ARE DESK LAMPS -  I prefer serious articulation, a desk clamp with some mass,  and arms that will stay in position -no weak wingnuts.

The handle has some weight to it.

 

It took some serious jury rigging to get a hose to fit the opening in the handle and also fit the dust collection port on my Byrnes disc sander. 

I use the tablesaw and thickness sander in my garage.  They are not about finesse.  The disc sander is.

 

An additional advantage is that it can be used to clear stair treads of dust.
