DIY wet/dry vortex vacuum

Yup, here are a few:

Just stick a pre-collector in front of it to take out the large stuff, and leave it to cope with the fines.

Thankyou most kindly John.

Guess which one I made ;-))

Next step is to 'plumb' in a set of take off points around the shed. One will be set up to the bandsaw permanently, two others will be flexi so I can hookup router, chop saw, jigsaw or sander as required.

Use smooth bored piping rather than corrugated flex. I think it was Phil who pointed out there are huge suction losses caused by such pipes. Static electricity is said to be an issue in dust control pipework.

For the take off points I will be using solvent welded inch and a half waste pipe and connectors, so no issue there. For the flexi part to the machines, well that is a bit trickier. Will be probably using very short lengths of corrugated flexi. When I use it as a floor cleaner, then corrugated flexi is really my only option at the moment. Would like to get hold of some flexible smooth bore tube of a suitable diameter, but financial limitations mean this is not a high priority. Sadly things like mortgage and bills are more important!

How will you shut off the unused take-offs?

Smoother bore tube is available from the various dust control outlets but is much more expensive:-(

Cork stoppers! nothing complex. I have some large bungs that came from a brewery ;-) hic, burp, washamatterwithafewpintsofbeerforlunchossifer?

Waste pipe has stop ends...

Very true, at a price. My way costs me nothing :-)))

Had not actually given blast gates much thought, they would be ideal of course. Trying to think of a nice, easy/simple to make gate. Most DIY ideas I have seen are for 6" dia pipework, mine will only be inch and a half, no heavy machinery in my shed!. Any ideas? :-) John

Mine are commercial 4" jobs; machined out of ally castings and bolted together. The *gate* being a steel slide.

You might take a 1 +1/2" coupler and fit a swivelling disc on a rod (carburettor choke mechanism)?

Just done some Googling, plenty of plans and ideas about, I like the swivelling disc idea, very neat. Thanks
