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!
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.
@@paulwelkinsdiy - I always have a couple rolls of the aluminum duct tape laying around - 1 in the workshop and 1 in the garage - oh! there is also one right here in my den that I used to tape Reflectix sections together! I have an 8 foot length of flexible vent already, left over from a previous project (added a heating duct to the laundry room in the basement).
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.
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.
@@notgivennotgiven7776 I do apologise. Life sometimes doesn’t allow me time to watch RU-vid everyday. Still, a compliment given late is always appreciated than getting none.
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.
Speaking of. I'm revisiting this since I'm taking electronics repair more seriously. Going to try and make something similar since the "proper" extractor I mentioned is awkward and not very helpful. Nor does it work well with just a carbon filter.
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 .
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!
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.
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.
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
I thought of keeping the exit port 8 inches instead of the reduced 6 inches. Not sure that would have helped. I'll put up with the occasional noise and keep the unit inside just to keep things simple.
@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.
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?
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 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?
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.
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.
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.
