Tonto, all my machinery lives in the corner of my shed, so I can have free space to work with.

hi Tonto, firstly, apologies for the state of my shed although, in all honesty, it’s probably representative of what it’s really like when I’m mid-project
This is the boom parked against the wall as it is when not in use...

and this is a closer pic of the boom hinge joint/s...
DF0FE19C-1B16-4D93-8D1D-C4A773E0B4B5.jpg
the required machine is wheeled out into a clear spot and the boom swung over to align with it. Note also that there is a 15A outlet at the end of the boom and a short length of flex to make the alignment less fussy....

There is another length of 150mm flex in the ductwork to link the fixed ductwork to the boom duct. This was, until very recently, the site of a manual 150mm gate but it has now been replaced by an automated gate on the other side of the wall...

and this general pic shows the other machines patiently waiting for their time in the limelight...

The drill press table is a bit rough and my only excuse is that this was to be a functional prototype but it worked so well that it has been in service now for a few years?

I’ll post some more pics when I’ve got the positionable duct working.a rock is an obsolete tool ......... until you don’t have a hammer!

Tonto - as you are starting from scratch you should be able to reduce the amount of flex used in the boom/wall elbow.
Something like this.

The workshop dust collection system is very close to being fully automated and, while waiting for the components for the first production gates to be finished, I’ve decided to pull my finger out and get on to some long neglected DC efficiency projects. I have 150 mm ducting to the end of the boom but then reduce it to 100 mm to connect to the drum sander, thicknesser, jointer or bandsaw. Dust collection from the drum sander and thicknesser in particular, would benefit from increasing the outlet to 150mm and they are the first cabs off the rank. The drum sander has a single piece moulded drum shroud and 100 mm outlet...
DCA561EF-5D16-4506-B646-F4A28FD7C815.jpg
and this shroud is barely 150 mm wide so fitting a 150 outlet could greatly weaken it?
A8D7FACE-7D87-4B5C-9FE3-8BFF250E26B7.jpg
Today i shaped a a piece of 150 PVC pipe to be a neat fit over the shroud...
D4BC5FE1-58EF-4A81-B68C-E9F77A40BB53.jpg
....and traced that shape onto the shroud with the black line being the pipe OD and the red line the proposed cut which needs to leave enough of the shroud for strength
94042D7B-753C-4E3D-9515-F8BC5BF4681C.jpg
The view from above shows that I am getting an outlet increase to about double of the original 100mm

However, I need to intrude into that area even further to add some steel reinforcing pieces which are glued and pop riveted to the shroud...

I have cut along the red line and glued the 150 mm pipe to the shroud so, while the glue is setting ....... it is coffee time!a rock is an obsolete tool ......... until you don’t have a hammer!

Nice work!
Wouldn't it be grand if the machinery manufacturers put a 150mm outlet and provided a step down to 100mm hose for those who want it? Doing it in reverse is such hassle, particularly for those without metalwork and/or welding skills. Should be an industry standard, IMO.

But that would mean the dc manufacturer would have to do the same and admit 100 doesn't quite cut the custard...

You have to remember that industry still operates with 1960's (OK I think it's 1969) OHS standards for dust based on English beech and oak. The current OHS standard only talks about amount of sawdust in mg/m^3) but makes no references to dust sizes and 100 mm ducting will meet this spec. Only in Europe have the industrial hygienists managed to convince some manufacturers that perhaps larger ports are needed but even then you might see a 125mm if you are lucky.
Just the other day when consulting for a local mens shed they showed me a DC ducting plan drawn up for their shed by a friend of a friend who was a pro ducting designer before he retired (which admittedly was a few years ago) - there was not one single 6" duct and for small machines he even had a couple of 2" ducts. I was pleased to see that the plan did acknowledge that manufacturers claims for DC CFMs were questionable.
About 5 years ago I consulted on a DC system for large (>150m^2) private workshop. The owner had obtained plan/drawing and quote (~12$k) for a spiral galv DC ducting setup and asked me to comment. Again it was all 4" at the machines except for one which was 125mm and I could not convince him of the need to go to 6".

I'm looking forward to the outcome of this modification. I have the CT version of this sander, and it has a laughable 2.5" port.

I’m not happy with the glue/sealant I used and so will REdo it tomorrow but these pics give an idea of the increased potential airflow on the drum sander. I have a couple of ideas for the thicknesser conversion and will need to convert that ASAP or it will be a bit ‘inconvenient’ having 2 of my main users having different ports?
