Dust Deputy
Got a Dust deputy from Carba-Tec on Monday, and got around to sorting it out today. Got it fitted to a plastic pail, and it is connected to my mdf CNC. A bit of clouting around with pvc fittings, and a bit of judicious resizing on the mini lathe, and it really sucks.
VERY happy with it, and can recommend these as a worthy investment. Mind you, I was testing it and accidently got the nozzle to close to my tracky jacket. Before I could blink, the plastic pail was trying (almost successfully), to turn itself inside out. Methinks I should make something in mdf or ply.Chris

Good stuff.
I've got the competition to that, but haven't yet got it hooked up as I hit a wall when I found the inlet to the cyclone is different in diameter to the hose on the vacuum. I'll get there one day.
Which ever you choose, I reckon it's a great investment.

I was thinking of one of these myself. Where did you source your bucket of the appropriate size?

I was thinking of fitting it with a homemade rupture disk. Is that what the foam is doing in your sketch?

No, the center disk is free to move up and down on the bolts and is held in place by the springs. When vacuum exceeds spring pressure disk moves - foam sheeting is used to form a seal.
Another idea is a tubular relief valve as per this sketch.Last edited by Breezy; 20th April 2012 at 03:54 AM. Reason: Added sketch

Back to the drawing board
I wanted to see how effective this would be with mdf, so last night I washed the vacuum filter bag. Turned it on this morning, and heaps more suction..........and yes, the pail promptly collapsed.
Need to get a heavier wall pail, or a 20lt metal paint can.Chris

I have one "permanently" connected to my SCMS.

Of course we know that dust collection from an SCMS is pretty well impossible so I also have this on a nearby wall and I turn it on by remote control to blast the excess dust out the open garage door on the other side of the SCMS...

Nonetheless, the dust deputy does its job well.
I also had problems with collapsing buckets.
At first it was the lid that imploded when I placed my hand over the inlet hose...

...and then after replacing the lid with a wooden one, the bucket itself got sucked in ...

My solution was simply to build a "squirrel cage" frame to fit inside the bucket. This was made out of a flat timber base that fits the bottom of the bucket and a flat timber top that fits under the lid with a large centre hole for the dust to pass through. The top and bottom have wooden dowels running between them around the circumference of the bucket which reinforces the outside plastic skin of the bucket.
I have not shown a picture because it is a pretty rough construction and needs to be a bit more elegant to show off but it works in keeping the bucket in shape. If I put my hand over the inlet pipe, the bucket sides still want to collapse but they are prevented from doing so by the squirrel cage frame inside.
Emptying the buck is a bit messier because of the presence of the squirrel frame so I don't see it as the final solution but it works.
I have the dust deputy and my Aldi shop vac mounted on a mobile base so that I can move the whole shebang around the workshop to vacuum, the floor. This is where the dust deputy is such a wonderful thing because it does pick up and separate out nearly all of the dust and who wants to be cleaning out the filters in vacuum cleaners?
I have considered building my own cyclone or variation on the theme such as the Thien separator but when Bunnings had the Dust Deputy at a sale price, it hardly seemed worth the effort of making one.

Here's my set up. Used it for a nearly 2 years now.
The MDF top is necessary to prevent the lid collapsing under the suction.

I cant see the point in spending so much money, time and effort into making complex relief valves to stop a $5 plastic bucket from sucking itself in. Surely it would be better use of your time and money to either buy or make a receptical that is strong enough to withstand the pressure. The absence of a relief valve also means there is one less component to fail and cause downtime in the shed.

If you only have a standard vacuum cleaner with a 32mm ID hose, here is how I connected it to my Dust Deputy.
