The sander is placed directly next to the DC cabinet. Checked the sound level with DC on at the sander, with the following result. I think thats pretty good, but let me know otherwise. Cabinet is pretty well insulaSound DC.jpgted but I could probably improve a bit, but dont think it is worth messing with at this time. More pressing things to do.

Also, I replaced the switch on the DC with a pole switch. I have connected it up to a powerpoint with a remote control adapter, as I have done with the exhaust fan. It is really good being able to switch on off anywhere in the shed. Particularly with the DC in a cabinet. It was a real pita having to open the cabinet every time I wanted to switch on & off.

Tell me more about your pole switch Baddabing! I have the same DC, am shortly moving into a larger shop and am interested in all you're doing. Cheers!

I took off existing switch & replaced with this: TOGGLE SWT -SHORT LEVER TYPE - Carbatec . I just leave permanently on, with the remote switching on & off. Better be politically correct and advise you use a sparky or the safety police will be all over me.
They also have a cover plate: Replacement Switch - suits many Carbatec machines (56x88mm plate size) | Electrical Switches & Leads - Carbatec . I didn't bother with this, just made one up.
My dusty cord runs out of the cabinet into a powerpoint fitted with one of these: Arlec Remote Controlled Power Outlet - Twin Pack | Bunnings Warehouse I have a different type but essentially the same. They work really well, and I think they would still work if powerpoint was in the cabinet, but not 100% sure. The big green shed sells them singularly and other various pack quantities. They may be a bit cheaper on amazon, not sure. Anyway, really recommend having the remote if dusty is in cabinet or externally located. Makes life very easy & I think these units work up to around 30m, not requiring line of sight, but please check the model before purchase. Hope that helps.

Connected the bandsaw up to the DC. It is a 14" Taiwan model, I think they and now China churn out thousands of these. It came with a 2" port in the bottom left hand side of the bottom cover. It never did much when connected to a shop vac, it was in the wrong spot. I used the 4" port I cut off the Big Gulp and located it on the right hand side up closer to the blade. I left the old port for airflow. Sorry about picture orientation, tried to rotate but didn't work

For dust collection, I used the 3 hose junction that came with the unit. Since 1 x 6" = 3 x 4" I thought I would place 1 hose above table, 1 hose below table and 1 hose into the bottom cover panel. I didn't have enough flexi hose so just went with 1 below table and 1 into the panel. At this stage I am just testing so everything is pretty much connected with duct tape (god bless it). I used a 100mm 45 degree angle under the table, just to see how things worked. WOW, what a difference this makes. The port under the table pretty much collected everything that was dragged by the blade below the table. I used to get heaps of dust around the bottom guide, now zero. The in panel port is collecting everything falling down into the bottom compartment, virtually nothing at all. On top of the table, the dust you can see has reduced by at least 90%. I will still probably try a port above table, but certainly in no rush to do so. Overall very happy with the set up. I will take of the 45 angle below table and make a bell mouth port, which should improve even further.

Just a heads up that those 3 way junctions are not conducive to efficient air flow management.
The 120º angles at which the air flow come together into the junction is highly turbulent and will reduce overall flow.
There a two aspects involved the first one being the angle of the junction, and the second being the number of connections.
Ideally the way to combine two air flows is with as small an angle as possible.
Here is one that I use on my BS that combines 3 flows using entry angles for 30º but the most efficient angles are <15º.

Unfortunately these take up a lot of space and no such junctions are readily available, with the shallowest of angles in stormwater PVC being 45º.
Another approach is to add a second 100 mm port to a standard 150-100 mm Y , like this.
Modified-Y.jpg
A more efficient way to combine 3 air flows (eg A,B,C) is to combine A & B using a "Y" and then combine the combination with C using a second Y.
I can understand that in some situations where there is limited room then low angled connections or other manifolds shapes etc need to be used.

Thanks Bob, I will come back to it after I get some collection hooked up to table saw, thicknesser and bench top jointer. I can probably knock up something like you have in the last photo.

Ahh I see. I like it, wasn't sure what you meant by 'pole switch' but it seems like a cheap and effective way to make my life easier! The only issue I foresee is that I'm going to be constantly looking for the remote, but I can't blame anyone else for that!
Cheers, Mark

I can't believe it has been 6 months since my last post. Heaps has happened keeping me out of the shed, mainly getting ripped off by a shonky builder for $15k who did a runner, but that's another story. Well, probably like all of us, Coronavirus has given me time to get back in the shed. I finally completed opening the dust port for my Thicknesser to a full 6" outlet. It works unbelievably well. Bob L if you get to read this, I found blocking the open end works best. All the air flow is directed through the Thicknesser. I placed my hand in it and you can really feel it drawing. I am certainly getting little to no shavings, and I think it is capturing nearly all of the fine dust. I had a 2" port on the end of a small plastic hood originally. It really didn't do a great job. Only drawback is I have lost a little of the maximum height I crank it up to, now get 150mm, whereas I think it went up to 170mm or 180mm. That should be fine for me, unlikely to put anything through thicker than 150mm. Here is a before & after.

Just to be clear, I cut of the front part of the original plastic hood that fitted over the cutter blade section. I fibreglassed this over a foam mould. I then fibreglassed this section to a piece of 150mm pipe, which had a 300 x 130 cutout in it. Here is the initial section.Fibreglas.jpg
