Thread: Carbatec Dust separator lid

The idea is valid.... the bin gets pretty full before chips start appearing in the DC bag. (Which is handy way to tell that the bin needs emptying. )

The outside port (which runs to your main duct) should have an angled exhaust added onto the other side, to start up a cyclone in the drum, which creates the seperation process.

I haven't used that particular CT lid, but mine's much the same thing made up from an old 44gal feed drum and a few plumbing fittings.

Wouldn't do without it.

Woodcraft have an article on how to make one - I used this article to make my own with standard plumbing fittings ( I used 100mm parts instead of the 3" specified). I even found out where to get the specified bin in Sydney.

What I meant to say in my first post (but somehow sidetracked myself ) was:

If you have a 44gal drum but no lid, then I'd look at buying that and adding an angled exhaust - and maybe short straight on the inside port. I don't think that I could use the CT lid "as is" for long without feeling the urge to tinker.

If you already have a removable lid & clip (as in a feed drum) then I think you'll end up with a better product if you modify that instead.

This is cut from a response to another thread (see https://www.woodworkforums.com/f8/dust-extraction-lathe-94785).

I used the C-T lid with an elbow inside on the intake to provide a sense of cyclonic action. It works well for me. Hope there is some info here you can use:

I bought a standard Carba-Tech 2hp dusty s/h with the lathe, thinking that this would be a solve all the potential dust problems. It didn't take long to realise that the standard filter bag that comes with this unit is not much use. I could smell that dusty-musty smell after doing some turning. This is of course the fine dust that has come back into the room through the bag filter. My solution was to seperate the bag/ filter assembly from the motor/fan assembly and put the bag outside the shed. I built a small "dunny-like" water proof structure from some old timber flyscreen doors cladded with some corrugated iron at the back of the shed. The bag/filter assembly inside this is connected via the 6in hose supplied through the wall into the motor/fan assembly. I placed this behind an existing partition wall to reduce the annoying motor noise. I then needed about 5m of extra hose to get close to the lathe. To optimise suction efficiency I placed a basic cyclonic bin on casters close to the lathe using a cut down old compost bin and a prefab lid supplied by Carba-Tech. The inlet hose connects to this lid from the lathe end and I have a hood fitted at the back and front of the lathe bed. This can move freely along the bed of the lathe.
I've had this up and running for about 3 weeks now, and I have had no more problems when turning. The heavy stuff that doesn't get caught still falls to the floor, but the light stuff has left the building! I am yet to reposition the lathe so that the floor space is optimised.

When sanding, I usually switch the dusty off and use a festool dust extraction unit with the nozzle very close to the job. I now have very little dust floating around the room; and the proof is up the nose - or not as in my case!

The only thing I regret having done was to cut the compost bin in half. I didn't realise how fast this bin fills up with shavings! - luckily I have another one which I might use one day.
BTW I hardly get anything in the plastic bag underneath the filter bag outside.

Sorry - too many words, so here are some pics from inside the shed.

Cheers,

Tried the lid, it was useless, I took it staight back to them the next day. Follow Skew's advice and instead make one out of a 44 gal drum.

Here's a WIP of my 2nd stage dusty which might be of some help. https://www.woodworkforums.com/showth...nd+stage+dusty

I've made a couple of separators of different sizes, one on a 20lt drum and one on a 100lt drum. Both work a treat.

For the 100lt drum I didn't hang the baffle from the lid, just put it on a leg that rests on the bottom of the drum with a clip to keep the baffle board from rocking around.
