DIY Workbench Mini Vac Cleaner with Trap

[Getunderit]

Got sick and tired of removing all tools etc just to access the sawdust, shavings, etc for cleaning.

When I was in the RAAF, we (Avionics Technicians) had a vacuum inlet on the workbench. A small diameter hose was attached for sucking up small foreign matter. We made our own traps at the inlet. These would stop anything we accidentally sucked up, like a small screw. Today, I made myself such a device. It attached to my vacuum cleaner.

 

 

 

Tested it on kitchen breadboard. The bread crumbs are on the bottom of the jar.

Looks very good, but it's a bit too organised for the likes of me.

I just brush the bits onto the floor in the hope that the carpet monster will gorge itself to the point that it won't eat my kit.

 

Hasn't worked yet, but you never know.

Please note that my drawing leaves out a length of hose from under the trap lid to about an inch from the bottom. It can be seen in the photographs. The hose was placed in to ensure deposits would be left on the bottom. If you like, you could add a small fly-screen filter over the intake tube of trap (vacuum cleaner end).

It has come to my attention that I once seen a similar device used by entomologists for collecting small insects. They used them in the field. They sucked on the vacuum hose. This device is called an aspirator.

Or, more commonly, in my experience, a 'pooter'
