That's one of those set ups you always wanted, but you usually don't get around to doing. Nice job!

Paul, as a nerd who’s watched way too many videos on shop air system builds, I’ve really got to say that your video has been the best I’ve seen yet. You’re entertaining but not at all annoying, straight to the point but don’t gloss over details, really looking forward to being a sub and seeing anything you’ve got coming. Thanks for a terrific video!

Paul that’s brilliant mate. Sometimes you just need to follow the pioneers I will be making a start on my copy this weekend 👍

Great job! They say that necessity is the mother of invention; I appreciate your initiative. : )

Very nice job 😊

Dave Elkins hoodie is pretty sweet. He must've been a cool guy. I made a jib boom for my shop and have attached an led shop light, an extension cord and a vacuum hose. I've been thinking about some sort of fume extractor for a while, thank you for motivating me. I think it'll fit on the jib just fine. I always weld with a respirator but when my machine hits the duty cycle my shop is thick with smoke. I need to do something about it. Again, I appreciate you sir and thank you for sharing your skills knowledge and experience

That aluminum duct tape is the bomb! I have used it to seal air leaks in my HVAC ductwork, AND on the rocker panels of my 2006 Chev Cobalt over solid rusted areas, before repainting the rocker panels. Two years in, and still holding tight! I will be stealing your idea for the exhaust ductwork in my basement workshop, venting it through the screened vent in the glass block window.

What you need is a large clear plastic dome or cone to do your work in like the cone of silence on Get Smart only maybe just large enough for your work and your arms and hands inside it. It could lower down on the workbench.

Paul I love all your videos,as I'm homeless ATM. I'm getting ideas for my 1 acre property in AZ.

That deserves a nice, DIY wooden louvre on the outflow. Reminds me of the articulating point vents we used to have in chemistry class. Those were mostly 2" PVC and pivoting elbow joints.

That;s my favourite video so far

Great idea and good execution only problem is on the out side where you flap is you should extend the exhaust side or overtime smoke and use will make a mess of your cedar siding .

I would recommend putting some sort of screen to block the entrance so that only air can get sucked through and not anything solid (like the paper).

Very nice, I have a 20 year old furnace blower I got for free that was being thrown away and it has 3 speeds on it, and is super quiet and was used in a 3200 sqft house, not sure what the CFM is for a blower of that size but it moves air so well. See if you can find a used or junked furnace blower and do a comparison on the flow. Thanks for sharing!

Good job Sir

Good idea and maybe took a lot of creativity to use whatever you had like a genius. Great job!

Nice. I tried doing something similar for soldering using a pc power supply unit case and a computer fan with some carbon filter material. Didn't pull enough cfm to do anything and just bought a proper extractor for $30.

That is great!

I wonder if you know my uncle Paul, he was an engineer for United Airlines a while back… maybe you guys worked together on a project or two while you were at Boeing. Anyways I love your channel! Very inspiring content! Edit, I just realized you live in Seattle… my uncle was in San Francisco back then.

if you want make a pipe with smaller connector you need a german round cake form i used one for my chimney to stop water running down into my wagen

You could add a screen to front of the collector to make sure no objects get launched into the wind tunnel.

Good one

I ended up going with a 6" 440 CFM one from Amazon designed for grow tents for weed, gonna run it right to the dryer exhaust vent since it's in my basement then add blast gates and a splitter so I can run a tube to my laser engraver tent and another one to my spray booth for painting and switch as needed.

This is a great idea and great work Paul. Well done buddy. I would have used the leaf blower to blow paper out though 😊.

Make a box outside and put the fan it there to reduce noise

Slickety! 👍

add a seive stop paper being sucked through

clever but still can be improved, add some air entrance somewhere so that it can push more as much air volume as it was designed to, put the fan outside so that you have less noise in the inside

@PaulWelkinsdiy Recently watched you on Kirsten's channel. What the insulation used in all those home delivery food boxes for your projects? So much insulation, card board waste. It's got to be good for reuse in some applications. Thanks for the content.

If the hose is going to come down past the arm that far, you might as well screw some kind of handle to it that comes down around the hose so you don’t have to go up on your toes to move it around. It could just be a loop of wire that pins into the foot of the canopy leg. That way it could wrap around the hose and (maybe) give enough leverage to even extend the leg. Maybe an old 5 gallon bucket handle? Might be a little too small once you bring the ends together, but that’s what I’m picturing.

I'm in Love With You're Heart and Mind. 👵🏻 God keep you and your Loved one's Safe

I wondered when i saw you making this if you were using a laser cutter on coro jobs but i don't see one. Dk you have any of the kayak designs available for share that are stored in .stl files for cutting w laser?

Great little setup. Hey, what about a taping in a bit of wire mesh or chicken wire at the nozzle?

Hey Paul... What if everything you own that's Chinese... suddenly disappeared?

My lungs will be thanking you next week Paul!

Maybe add a wire mesh to the vent

hi paul, im designing an e-bike/motorbike trailer with fold down sides that form a circular platform for a small heavy insulated yurt. feel free to play with this idea and see what you can come up with as a portable warm survival shelter for the homeless. campers are great but i wanted the comfort the space a yurt provides and its simplicity for insulation and nomadic lifestyle. which materials would you recommend i use for long term durability, warmth and lightweight construction?

Would you be interested in making something to cap smoke from something like a wood burning stove to feed it into a home Spirulina or Chlorella system? Kind of like a home version of how they say they can use emissions from power plants to feed algae production for algae based biofuels, plastics and fuel? There's lots of videos on how to grow those algaes and process them at home, but no one has bothered to use smoke from biomass burning as part of the nutrients. The closest I've seen is them settling for the carbon dioxide in ambient atmosphere and just using an aerator or fish tank bubbler.

hopefully you don't end up with mice problems. i found em gettin into my oven vent. those little jerks :)

Is there anything securing the ducting in the wall?

You built a 2 for 1 contraption. If you remove the grill cover you could have a shredder too let’s try that paper trick again. Lol.

What baffles me in these kinds of projects - why no one is using a centrifugal fan - has more pressure to squeeze all that air through the hose, more velocity, more better.

Too late for me, I spent 5/6 years in the Structural Steel business breathing in every nasty fume imaginable. What ever damage is done is done and I can't go back in time and change anything now.

Paul. This comment is misplaced as it is not relevant to this post. I’m working on a plan to build a micro camping trailer to pull behind my motor scooter. Do you think coroplast can withstand winds in excess of 70mph! My other option is pink foam with poor man’s fiberglass.

Ok

Still da' man!
