Thread: 6" ducting plan

Originally Posted by lovetoride

At a pinch a tall pot plant pot can be used.

Lathe - I plan to run 6" flexi to the lathe and make a bell mouth hood.
Sander - I can make something up similar to BobL's disc/belt sander extraction and hence use 6" there.
Bandsaw - Not sure about the bandsaw (Jet 18") with one existing 4" high in cabinet behind lower guides. I know the ideal is to change the bandsaw outlet to 6" but can I leave it at 4"?
Triton TS/Router - Something will need to be constructed for the Triton table so should I be looking at 3 x 4" for that?

Good to see you have been reading the forum

I also need to consider the air escape path which I was thinking of placing up high and at the end of the enclosure at the other end from the inlet. Oh and I need to line the enclosure but I think I should be fine with that.

Don't forget to make sure some escape air goes past the motor for cooling.

Unfortunately when I was re-reading the thread on your setup BobL the photos I wanted to see again are gone

What would you like to see photos of?

Well I reading through the sticky FAQs and then headed to this link on your enclosure. Really just rereading material and looking for ideas on what I need to do for enclosure and also for in shed connections.

Any feedback on whether my plans are appropriate?

Looks pretty straight forward. You haven't indicated where the blast gates are to be located but I assume you know it's generally better to have these located near the trunk line.

I was thinking a blast gate on each of the Y-junctions

Hi LTR, just a little thread hijack if I may....kind of relevant to what you are asking about.

Bob, if you have a minute I would really appreciate a photo of your baffle arrangement , particularly where it is mounted in relation to the motor and bags of your dusty.

Cheers,

Photos very difficult to take as the DC enclosure is jammed into gap between fence and shed.

Here you can see th stop of the baffle box under the motor.
It doesn't look like much of a gap but there is a gap behind where where the air goes on

Thanks very much Bob.

Just posting a photo of today's purchases - because I can

Just about finished mine. Started with a 6m pipe and 3 x 90 degree elbows then some 45s then some "y" pieces then some ...............................

Bits and pieces sure add up don't they

I'm in the process of determining what to use to line the DE enclosure to minimise noise. It is constructed with colorbond sitting on a 900 high besser block wall base.

I have a bag/roll of Fletcher Permastop Building Blanket (nominal thickness 55mm) whose main role will be to minimise condensation.

I am considering maybe mdf (16mm?) and/or Bradford SoundScreen batts (70mm) but the studs are <90 deep. I think it was recommended on one of the threads that the mdf should probably go towards the outside (next to the sisalation stuff) but I would then have problems with thickness if I also add the batts. I could put the batts towards the outside and then add the mdf as the internal layer (and to hold the batts in) and sit it across the studs rather than between them.

So... do I need mdf AND soundscreen batts?

The two hinged doors are 2.3m x 800mm with the frame only about 40mm deep. They are 6mm marine ply. But I don't want to add much to them with weight.
The whole enclosure is up against the corner of the yard so with 1.8 colorbond fence next to the back and 1 side.

The order is not that important, we're not building a recording studio.
Something dense and something not so dense.
Put the bats in between the studs and the MDF on top of that.

They sure do.
My current system was started to be put together and services BS, TS, Router, jointer, sander, DP, power tools.
It has 5 arms , 9 x 90º bends (some are pairs of 45's or made up of 15's) 10 Y's, 11 couplers, 12 gates, 5 reducers and 5 Bell mouth hoods.
