A classic ILTMS video that reminds me why I first sub’d. Your vids are consistently of the highest quality, it’s great to see a variety of subject matters and run length... but personally I enjoy the longer projects where you show your thinking, your approach, and mistakes you made along the way. great running into you and your wife @ MFNY
You probably just saved my life. I'm a solitary engineer, & I usually think things through really well, but I was going to add a small fan inside of a flexible dryer duct leading outside, with a fume-hood inside. But then you said "fumes passing over a motor" & I couldn't believe I missed that part in my plans. Thank you sir.
I still would not recommend his fan setup. Yeah the fan motor is outside the air flow, but that blower cage is not explosion proof due to the rotating cage bearings and overall construction. Better to get an explosion proof fan.
Several years ago, I bought a brand new truck without a radio installed. That also meant it didn't have an antenna. I was tense drilling a hole in my brand new shiny fender.
I really like the way that your buddy films the action. He gets close enough to not only see what you do but make it a great focused and pleasing shot.
Pocket holes, Bob? You know it's gonna fall apart. :) Just kidding. I've been waiting to see this one, I love the simplicity but super function of it. Two thumbs up from me. It was nice to Josh too!
Daisy chaining the ventilation system to accommodate the laser, paint booth, etc is a great idea and solves having to have dedicated systems for each! I plan to add air filtration to vent fine particulate dust to the outside in addition to my air cleaned inside.
Just about to pull the trigger on building your previous one with some changes to the design, then you release this, which is exactly what I was about to try and do. Thanks for solving many of my problems for me! Great video.
I've lost track of the number of times I've heard Bob say "I've never really done this before...." in his videos and then watched it come out perfectly. Great project!
Michael Gomez he did a video a while back on a smaller foldable painting booth if that interests you! I plan on making one to spray my foam and plastic cosplay pieces without getting loopy from the fumes
GREAT BUILD! If I ever get a shop I am building this paint booth. Right now I just work in a large shed outside and I just leave the two big shed doors open when I spray paint so no need for a ventilation system. The small paint booth like space is right at the front of the shed right by the doors that will be staying open while I paint something.
One thing you may want to add is a fresh air inlet vent, otherwise you may get reduced airflow from the negative pressure. I currently just open a window when running our laser extraction fan, helps increase airflow. In my other shop I added an external inlet vent for when the paint extractor fan is on.
Oh ! You weren't kidding when you said paint booth. Nice work Bob. We love watching you guys plow through the problems and find the solutions. AND WE NEED MORE BLOOPERS. Durp, durp!!!!
This is wonderful. We are beginners and are refurbishing our Christmas blowmolds. This design is simply genius and simple at the same time. THANKS for posting
Just got back from watching The Last Jedi and soon as I saw a new video from you I had to watch it to calm myself down from how awesome the film was. Keep up the great work.
As a guy whom does duct work for a living, I was screaming about upsizing until I saw the note about you changing to 6". Came out great and looks good. Great project and video as always. In the future you can use a "ductulator" (they're like 20 bucks on Amazon) to figure out pipe sizing based on desired/required cfm.
Great vid Bob as always. Like the detail you put into your videos and admitting you make mistakes. I couldnt tell you a project that I've done that hasnt had to have the plan changed or overcome some obstacle along the way. Thanks again and keep up the good work
Great idea! Totally didn't think about the whole paint fumes over an electric motor... Thanks for saving me from burning my garage down!!! Really digging the longer format too!
Guys, it's not sparking from the motor that causes explosion. Induction AC motors don't spark, only brush motors spark, and those are most often DC. But the thing you want in your explosion proof fan are the fan blades, casings and epoxy coating on the blades, so they can be cleaned. In high-demand shops fan blades are literally coated with over sprayed paint. This in turn can kick the blade out of balance, it can fall off the main shaft and hit the casing, causing sparks. That's also a reawon why most booths are sheet metal and electrically grounded.
Very interesting video. I did a smiliar project for a welding fume exhaust system in my basement. I used a fan like yours and made the same initial mistake of using a too narrow pipe with it. I started with 4 inches, like you, and I ended up with an 8 " one. Works great !
When I saw you throw that scrap 2x4 away I was like “nice shot, but that’s a waste”and then you went back for it. Only one of the reasons you’re my favorite
Great video as always. I really do enjoy your videos and I know that several of my German maker friends do as well. Keep up to good work, Bob! Best Regards, Daniel
Thanks for sharing Bob , I have been enjoying your podcast with Jimmy,David, while I have been healing up from my hospital stay! I meet Jimmy at his house back in April of this year. That what got me to listening to the podcast. And I found you and David . Best Regards BobLee
There is one golden rule in aerodynamics when It comes to pneumatic transport of particles through pipes using fluid mediums such as air or water: - When two pipes connect into a single pipe, the diameter of the single pipe should be a sum of the diameters joining into that single pipe. For example: If you have 3 suction openings connecting into one single pipe, the diameter of the single pipe should be 9 inches. By doing this you are maintaining proper static and dynamic pressure in the pipes and avoiding turbulence, which provides sufficient suction at the suction points and that way you are using the full potential of your ventilator. Also using gradual angles of air streams joining prevents getting feedback of air through the suction points and prevents turbulence.
Keep up the amazing work! You have inspired me to start woodworking. I recently had a traumatic accident happen to me and i am finally able to get back on my feet and start woodworking again thanks for the hard work and dedication bob
Really enjoyed this! What a cool project! I liked seeing how you solved all of the little problems that you came across. Oh, and stop clearing your throat. ;)
I think I can honestly say this is the first time I've seen a maker use duct tape in a build for duct tape's intended purpose. Great work Bob! I needed to re-do my paint booth for airbrushing and this gave me some great ideas.
I just did a side-by-side of this video, the Christmas Cannon (best way to decorate a tree ever!!) plus a few others, old and new, and I do feel that this video's voice-over was better. Maybe it was your delivery, proximity to the mic, or post-processing but it just sounds warmer and clearer to me, but, like a lot of things, audio is just about personal preference.
I have a project for school and it needs alot of paint and i need a paint booth like this so i showed this to my dad and he got the idea for making the paint booth. Thank you Bob! Stay Safe! 😁
I Like To Make Stuff I figured so. Just I know you said you didn’t have the amount of suction you wanted so that would be one upgrade. Thought it is much more expensive. All in all great video though and I appreciate all the stuff you do. Gives me ideas and solutions for stuff I would have never even thought of.
@@Iliketomakestuff The aluminum tape actually works much better, as ventilation piping is its intendid application. It seals better, and has a much better longevity. Air leaks tend to dry out the gaffer tape.
Hey Bob, I'm a 21 chemistry student and I think I'll never make anything of the stuff you do here but I love watching your videos and learning somehow how to make stuff. So great job and thank you!
The idea of using a translucent medium for the booth to allow for proper lighting is really cool. I always have problems to judge if everything is properly painted in all areas! Thanks for sharing!
So, here’s a quick and easy way to increase the draw on your booth without having to put larger ducts through your shop... add a plenum (just a fancy word for an air tight box) to the intake side and run multiple smaller ducts to the booth. You’re still going to have to run a large exhaust duct to the outside (or multiple exhausts off an exhaust plenum). Just be sure the surface area of the diameter of the intakes roughly equals the surface area of the exhausts at their most restrictive points and you should achieve the best flow possible. (Example: a 4” joint of ductwork has about 12.5 sq. in. of surface area). And be sure you allow about 1 sq. ft. per ton of the furnace unit your squirrel cage fan came from or you risk burning up your motor quicker than normal. Great vid!!
Filtering the air that goes outside? You're nicer to your neighbors than I am! Lol. (Really like this, btw. Old blower fans like that can be super useful, especially for the common price of free!)
I really like this format, and I don't care how long you make your videos. I will watch every one you put out. I used to core drill concrete as an electrician, in this case you would want to turn off the hammer drill function (why the mortar vibrated out) and just use it as a drill. A water drip would negate the dust and prolong the diamond coating while helping remove the waste.
This was awesome. Very informative especially the part about the pipe not being big enough to draw enough volume of air to suck all the fumes out. I’m going to have to build one now. I can definitely use one. Thanks Bob!
FWIW I’ve had issues with gorilla tape staying stuck over the long term the adhesive separates from the tape fabric. If it fails you, a great sealing alternative is foil tape. It’s quite a bit more sticky and you can burnish it down into the gaps and such to create a nice seal.
Really I was just trying to be silly, but you may have a point there. Might be something to consider given the application is to attempt to contain the fumes.
Yeah, silver flashing tape would be better, as it's designed for this application. (I've seen enough This Old House to know never to use Duct Tape(tm) or it's variety of knock offs.) BUT, if the pipe is piped so that the direction of airflow goes with the male ends of the pipe point to the exit point and the female ends point back along the path to the machine, it shouldn't be too much of an issue? He'll just have to make sure he periodically inspects the system for leaks. (Maybe it's time to invest in a smoke machine?)
Nice. I have a small basement shop. I am designing a knockdown booth because there's not enough space for a permanent one.. I only use water borne finishes, so it's easier to get right. This video gave me some ideas for sure.
Great video! I'll be planning a spray booth soon at my new place and don't have a lot of space so the fact that this design can be sized is good to know. One thing with the coroplast is that it's usually better to use washers with the screws, especially on those edges that will experience movement like around the doors. I used to work a lot with coroplast at a couple of sign companies I worked at. You will see the coroplast wear around the screws over time.
If you neck it down too much it creates back flow as the air has to go somewhere if it can't get out the exhaust it backs out, you could neck the 6 down to 4 again once it's in the mainline flowing.. I had the same problem years ago when I made mine,,thanks nice stuff.
I am kinda new to make stuff but when I watch your videos it just fills my head with such fascinating bulids, never stop making videos and your builds are just amazing
I don't have the means or space to do what you do, but you are a huge inspiration for me. When I finally move and have the ability to do things like this, I will definitely watch through your videos again. Thanks or bringing your passion to people like me. You are awesome, keep up the great work!
For the paint booth section of pipe, i plan on just using intake ducting @ the size of the blower, and where the blaster gate is for the laser, i would use a coupler w/ a 6" tee'd off @ 45* for a simple Venturi .... If you need more suction for the laser, just close up the paint booth or create a sliding blocking plate to control flow @ the booth... Copying the booth design for sure, much nicer than what I planned
Very nice project! I love when you realize that the exhaust vent doesn't fit properly outside; this type of problems happens to me all the time! On a side note, Gorilla tape rocks but for metal assembly, aluminium foil tape is way way better, plus it's more discreet as it matches the metal color.
Hey Bob! Love watching your stuff! Honestly, I dont have the space or the need for such a large paint booth like this one, but the techniques and supplies you use and seeing how you work around little problems such as the issue with drilling out the bricks make every video useful no matter what the subject matter is! Keep up the great work!
I'm Sam, and I like to watch you make stuff. Great video and some great ideas here. I think you should have used some foil tape on sealing up things though.
Great project Bob! I was just talking to my wife about building a small spray booth in the garage and finding a way to eliminate fumes so it doesn't leak into the house. I'll have to see if I can modify this design to fit my shop. Might be able to link it to a larger plastic spray booth so I could spray finish on tables and other larger pieces as well.
I was only looking to knock up a quick cardboard box spray booth, but instead I find this and get sucked in to watching a 16 minute video! Goddamn my love for DIY.
Still envy all the shop space... so much! Interesting choice to not add music, I noticed it, but it might actually have helped me focus on the info better. Great job ILTMS team!
Thanks for following up when things don't work as well as planned. I appreciate that you share that part with us.
Long video is no problem as long as we are learning something . And yes we did learn a lot .
Thank you

lol... been missing the outtakes man... thanks for throwing those in there... "derp... doop doop doop.." hahahaha
Hey bob, your videos led me into a passion. I'm into fine woodworking now, but your videos inspired me to get into building. Big thanks bro!
Cutting a hole in your house is always the scariest part of any project 😉
Eh, I beg to disagree. You've never plumbed for gas and had to hook up the line.
Several years ago, I bought a brand new truck without a radio installed. That also meant it didn't have an antenna. I was tense drilling a hole in my brand new shiny fender.
It multiplays by hundred when you're living in a block of 20 apartments that is about to collapse.
Really funny and scary adventure. 😉😁
EvanAndKatelyn Bob once cut a 3inch hole in his truck in order to install a snorkel..
The scariest part of cutting a hole in your house is waiting for the wife's reaction when she comes home and sees what you did.
Its so interesting to watch you videos, Bob! I dont make anything myself, but I love watching you make all the stuff! :D Great job!
Same!
I really like the way that your buddy films the action. He gets close enough to not only see what you do but make it a great focused and pleasing shot.
Thanks! That's awesome to hear :)
Tying in the laser to it...briliant! This could totally kill two birds with one very large squirrel caged stone. Good stuff, Bob!
I’m glad I’m not the only one that does that kind of crazy stuff in the bloopers Doo doop doop boop badupe doo baduppe !!!!!!
Pocket holes, Bob? You know it's gonna fall apart. :) Just kidding. I've been waiting to see this one, I love the simplicity but super function of it. Two thumbs up from me. It was nice to Josh too!
Scooter's Workbench Yes. Why pocket holes?

"Sorry this was a long video" Bah... there is no such thing as a video that is "too long" if you are making it.
The more the better.
don't steal my life
H4IZY ok
Helpful additions: lazy susan platform, a rotating spoked wheel, near top to hang items from while painting.
Mate, please do a shop tour!
Still have some more stuff to build out, but I will one of these days 👍🏻
Sounds great!
Keep up the amazing work! You have inspired me to start woodworking. I recently had a traumatic accident happen to me and i am finally able to get back on my feet and start woodworking again thanks for the hard work and dedication bob
Glad to hear you're back up and running Alex!! Have fun!
Really enjoyed this! What a cool project! I liked seeing how you solved all of the little problems that you came across. Oh, and stop clearing your throat. ;)
The only channel where I give thumbs up before I watch it

Great project/video Bob. Your voice-over sounds really good too, anything new or is it just me? Enjoy Star Wars!

Different mic but I honestly thought it sounded worse. That's really interesting to hear from you.
I just did a side-by-side of this video, the Christmas Cannon (best way to decorate a tree ever!!) plus a few others, old and new, and I do feel that this video's voice-over was better. Maybe it was your delivery, proximity to the mic, or post-processing but it just sounds warmer and clearer to me, but, like a lot of things, audio is just about personal preference.
That was very comprehensive. I have often used a box fan. I never even considered the danger of the fumes over the motor.
Love your longer Vids
I have a project for school and it needs alot of paint and i need a paint booth like this so i showed this to my dad and he got the idea for making the paint booth.
Thank you Bob! Stay Safe! 😁
Great! Thanks!
@I Like To Make Stuff, you're my inspiration! ❤️
Nicely done Bob!
Love how you do your mid-roll ad copy. Brilliant way to show some love to your sponsors while maintaining the momentum of your video.
You really need to use the silver ducting tape that is recommended for hvac applications
This isn't an HVAC setup. Not really a concern of mine.

Amazing vid as usual!
You are the reason that I want to do woodworking and engineering when I grow up
Durp, durp.
Great video. Glad you didn't split it up into two.
Filtering the air that goes outside? You're nicer to your neighbors than I am! Lol. (Really like this, btw. Old blower fans like that can be super useful, especially for the common price of free!)
Why does your son have such luscious hair?
That's my daughter.
I Like To Make Stuff Lol Sorry my bad, I always thought you only have a pair of boys. The boyish clothing made her look like a boy from the back.
I really like this format, and I don't care how long you make your videos. I will watch every one you put out. I used to core drill concrete as an electrician, in this case you would want to turn off the hammer drill function (why the mortar vibrated out) and just use it as a drill. A water drip would negate the dust and prolong the diamond coating while helping remove the waste.
Bob do you excited about upcoming star wars movie?
Ummmm YES!!! :) Going tonight at 7pm!
I Like To Make Stuff Im Goin tomorrow to see it!!
In 3D!!!!
Hurray!!
I Like To Make Stuff Have fun! No spoilers.
already watch it
I Like To Make Stuff SAME
This was awesome. Very informative especially the part about the pipe not being big enough to draw enough volume of air to suck all the fumes out. I’m going to have to build one now. I can definitely use one. Thanks Bob!
why now bob? i was about to sleep right now
It'll be here tomorrow :) Go to bed!
Great video! I think I will use this idea in a way in my metal work shop building. By far the best video on RUclips! Thanks
I inhale my fumes like a man
FWIW I’ve had issues with gorilla tape staying stuck over the long term the adhesive separates from the tape fabric. If it fails you, a great sealing alternative is foil tape. It’s quite a bit more sticky and you can burnish it down into the gaps and such to create a nice seal.
Who’s excited for STAR WARS
Bob by now you probably know I love your videos. Thanks a lot 👍👍
👍👍👍
I'm going to build an automotive paint booth, but I'm looking at all the videos I can get my eyeballs on. Great info, thanks for taking the time!
Thumbs down for using duct tape on actual ducts.
Hahaha
The glue in the duct tape is going to dry out and lose any seal you had... Foil tape lasts darn near forever! And its shiny! Great build though!!!
Really I was just trying to be silly, but you may have a point there. Might be something to consider given the application is to attempt to contain the fumes.
Yeah, silver flashing tape would be better, as it's designed for this application. (I've seen enough This Old House to know never to use Duct Tape(tm) or it's variety of knock offs.) BUT, if the pipe is piped so that the direction of airflow goes with the male ends of the pipe point to the exit point and the female ends point back along the path to the machine, it shouldn't be too much of an issue?
He'll just have to make sure he periodically inspects the system for leaks. (Maybe it's time to invest in a smoke machine?)
Jack Linde lol up here in Canada it was Holmes on Homes, “Duct tape is NOT for duct work”
I bet your neighbours are happy with the new air quality they will be getting
Nice. I have a small basement shop. I am designing a knockdown booth because there's not enough space for a permanent one.. I only use water borne finishes, so it's easier to get right. This video gave me some ideas for sure.
Like the baffle idea, will have to add one in front of our filter as well to help reduce the filter loading.
Enjoyed the longer video and extra detail! Awesome!
Great video! I'll be planning a spray booth soon at my new place and don't have a lot of space so the fact that this design can be sized is good to know. One thing with the coroplast is that it's usually better to use washers with the screws, especially on those edges that will experience movement like around the doors. I used to work a lot with coroplast at a couple of sign companies I worked at. You will see the coroplast wear around the screws over time.
If you neck it down too much it creates back flow as the air has to go somewhere if it can't get out the exhaust it backs out, you could neck the 6 down to 4 again once it's in the mainline flowing.. I had the same problem years ago when I made mine,,thanks nice stuff.

I’m sure it’s been said but, if the content is of good quality the length of video doesn’t matter! Good work as always Bob.
I don't have the means or space to do what you do, but you are a huge inspiration for me. When I finally move and have the ability to do things like this, I will definitely watch through your videos again. Thanks or bringing your passion to people like me. You are awesome, keep up the great work!
My guy, THANK YOU. This was very informative! Baffles are crucial and yes 6" is about the minimum you want to use in these scenarios. Great work!
For the paint booth section of pipe, i plan on just using intake ducting @ the size of the blower, and where the blaster gate is for the laser, i would use a coupler w/ a 6" tee'd off @ 45* for a simple Venturi .... If you need more suction for the laser, just close up the paint booth or create a sliding blocking plate to control flow @ the booth...

Honestly, I dont have the space or the need for such a large paint booth like this one, but the techniques and supplies you use and seeing how you work around little problems such as the issue with drilling out the bricks make every video useful no matter what the subject matter is! Keep up the great work!
Aluminum hvac tape would be the ticket in this application
Really like your design. Will build one for my shop and connect my laser as well. Thanks for the great video.
I'm Sam, and I like to watch you make stuff. Great video and some great ideas here. I think you should have used some foil tape on sealing up things though.
Great project Bob! I was just talking to my wife about building a small spray booth in the garage and finding a way to eliminate fumes so it doesn't leak into the house. I'll have to see if I can modify this design to fit my shop. Might be able to link it to a larger plastic spray booth so I could spray finish on tables and other larger pieces as well.
I was only looking to knock up a quick cardboard box spray booth, but instead I find this and get sucked in to watching a 16 minute video! Goddamn my love for DIY.
Still envy all the shop space... so much! Interesting choice to not add music, I noticed it, but it might actually have helped me focus on the info better. Great job ILTMS team!
