Great build! Pro tip: When caulking the vents on the outside, only caulk the top and sides. Do not caulk the bottom. If moister does find a way in around the top and sides, it will have a means of escape at the bottom and will not become trapped.

make sure the temp inside dose not get above 120f with derating or 100f for normal rated use. chris has a good design, two things: up size the fans to 12" the one on the back have it ducted directly to the back of the alternator (gen end for those not in the generator industry) 99% of failures your going to see is the alternator overheating and failing. they are VERY sanative to heat.

I found it over the years the threads on the exhaust pipe are generally the same as half or three quarter inch pipe. So I always take the exhaust pipe and small muffler off and run pipe a couple feet away straight up in the air outside the building changing it to 1 in pipe after about a foot from the box and then put in a 180° curve on the top to keep rain out not only does it get the exhaust fumes up in the air and away from people it further quiets it but by about 20 decibels

Man, you really be going above & beyond for your viewers. Been watching for a while now.. you're a modern day hero man, keep it up!

Kris this is incredible. And you are so helpful to provide all your steps and how you made your decisions! I hadn’t thought of putting my generator in something like this for using it. Wow thank you!

Nice one Kris, Thank You! Something my Grandfather once did was use some metal struts to make a cage for the generator, then he used some strong springs and suspended the generator from the top metal struts so it was hanging. Makes a world of difference on the sound and vibration.

Well done. I'm thoroughly impressed. You've thought of everything!!

This actually inspires me to build something similar not for a generator, but for an air compressor for my shop. I don’t have a lot of floor space in the shop, so my thought was to build a lawn and garden shed and put the compressor in there, but it would be too far away from power and too far of a run for the air supply. This is just about perfect and I can set it up right next to my workshop, eliminating those two concerns. Thank you!

I’ve been trying to think of a way to knock down the noise from our generator. You sir just showed me what I need to build. Thank you!

This is one of the better videos I've seen & covered my rear. I "WAS" gonna use foam board but quickly changed my mind after watching. I just want to do it right regardless of costs.

Love this! Thank you for posting this. I'm actually planning on building out a generator shed, your timing is perfect.

I have a Firman 10,000 W tri fuel generator In a box similar to yours. I live in PA and have had to use it on many occasions. I do not us the sound dampening boxes, I found.they make little difference and hold heat. Before attaching another muffler, CHECK YOUR WARRANTY! Outsourced mufflers change the compression and will cause failures it also voids most warranties. We live in a world now where people see you have something they want so they steal it. I had a welder make me two 4 ft.rebar pcs with steel rings welded on that I drove 3/feet into the.ground, cemented in and ran steel cable through with a heavy duty lock. I highly recommend hard wiring the generator to your panel by a qualified electeician. Electricians and in our area call the plug-in the "pig tail of death" many people start their generator, THEN plug it in, which is a good way to get electrocuted. You DO NOT need another box, just a simple transfer switch that prevents you from back feeding the lines. You cannot power your box until the main switch is off and then the generator breakers can be flipped on. Also, flipp the breakers to the items with the highest draw first. Once.I learned that I can now power my whole house. And make a schedule to run your generator at least every two weeks and check the oil. It is a great feeling to have this item as a.back up.

So glad you got around to this project! I know you have been buried with more urgent issues for us to address! Thanks!

The spring idea is fantastic.

Great job, well done. Here’s a tip to reduce more sound. Get about an inch stand off with a piece of plywood that’s a little larger then the exhaust opening. Add the stand off and the plywood on the inside to cover the exhaust opening. This will help baffleing sound more.

Very cool video! I actually have this project on my to-do list as well so I’ll definitely be referencing this video when I do!

That was fantastic! I was just starting to think about building one for mine. First I have to see if the hoa lets me have a shed outside! As always, thank you!

Great thinking re: the rubber horse stall mats! I never would have thought of that use for them. I might pick up a couple extras when I go buy them for my barn.

Sweet build. Been thinking about something like this for a while now

You did an amazing job on that project! Great job Chris 👍👍

This was GREAT Chris! Thank you. If you do another, or want to modify the exhaust pass-thru; A tankless water heater exhaust thimble is perfect for this job. Does the same thing your custom 'thimble' does except pre-made to route hot exhaust through combustible materials.

Nice work. I see you watched some of my videos on building a quiet generator shed and put the ideas to work. Glad to see some of these ideas showing up in other videos in the wild. That's the beauty of KZfaq!

I've been waiting for this video since you mentioned about it months ago. Well worth the wait. Thanks so much for posting!

Superb bodging skills mate. I think its really good to develop the skill set required to fabricate functional items, especially since we might all be forced to do this kind of thing more in the future.

This is excellent, I can't justify the whole home backup system for like $12k right now but a ~$1k from Costco or whatever inside an enclosure like this is feasible

Nice job and gentle, smooth explanation. Thanks!

Great video!! Thanks for the information and perspective on this build 👊🏼🇺🇸

This is brilliant! I’m downloading this. Thanks, Kris.

Very cool build!

Great work!👏🏾

Thanks! Your instructions are so clear, even I can do this project!

Very nice! I've got something similar going on except I placed the box in my basement and vented it outside via a Vortex inline fan. In the event of a prolonged outage I don't want anyone hearing/knowing that I have a generator. I realize this comes with extra risks but I've got carbon monoxide detectors nearby. 100% grey man set-up.

Great project Kris, thanks for sharing!

Great build Kris!

Thank you! I “went ahead” and watched this video. Liked !

Awesome. I was wanting to make one but hadn't started the process of figuring out how. Thanks!

Very cool Kris!

Very well done. Thanks Keis

WOW, AWESOME VIDEO KRIS THIS WOULD BE SOMETHING I COULD DO FOR MY GENERATOR, THANK YOU FOR SHARING THIS WITH US.

Looks like it was a fun project. Nicely done 👍

Thank you for posting this. I may give this a try.

Good evening from Syracuse NY brother thank you for sharing your projects

Good job! Thanks for sharing everything!

Fantastic job!

Nice build, thanks for sharing.

Thanks for making this vid! The exhaust wrap is a lot easier to work with if you soak it in a bucket of water for several hours first

VERY NICE!! I have the same unit assembled and ready to finish come spring thaw. I will copycat your process. Thanks!!

Impressive results!

Great video. Valuable information and it’s well put together 👍

Good video Kris, thanks!

Nice build, thanks 👍

Awesome build

Thanks. Great job!

I enjoyed the video, I have been looking at doing this same thing. Thanks for the ideas.

Well done!

I love these kinds of videos as a contrast to informational/news update videos. A bit out of my means personally due to the amount of materials and time and engineering prowess but nevertheless it’s a very Impressive build to watch.

Great work

Great solution thanks for the video. Awesome.

Wow! I really like what you did there. I like that you payed attention to detail as well. I am the same way with the details. Going with the rock wool was key. I wouldn’t have used anything different than what you used. I do a ton of project and use a wide array of tools and devices and I can see that you used all good quality products and methods. Super super happy for you. 🧠🏆🧐

Nice job!

Best video you ever made!

Very practical, thanks

I would recommend using a patio container with a fan for exhaust. Some fit perfectly around the generator.

Great idea.

Thanks!

This is genius. 💫

Great show kris

thank you love the ideas

Hey thank you for making this video you are the best

I need a box of those nails!! Those nails are amazing. 11:14

Well done. I thought you did a pretty thorough job of addressing everything needed to do a build like this. I think you did a better job than most of these complaining keyboard DIYers would have done. Obviously someone can easily add or take away anything they want for their ideas. I have a old 4500 watt generator that is incredibly loud and wanted to build something for it. Ideally a little smaller and something that I could setup and move easily. Thanks for your ideas.

Very good video! Thank you...🇺🇸 😎👍☕

I have done this several times, you are correct, the fan is too small and you should be blowing air INTO the box not exhausting air, it is much more efficient. Also a "Certified Exhaust Thimble" for combustible walls should really be used as fire codes are not a bad thing.

Good job.

Very nice 👌

Cool idea. During the last ice storm, I could hear generators running throughout the city. With the usual noise pollution levels way down, it seemed like the sounds of generators traveled quite a bit.

Nice box! David Poz just released a video on making a generator/charger using an old treadmill! If the zombies arrive, put the old treadmill to use!

I saw what you did there with the nail, I like it.

Thank you!

Dude Great job and tyvm for the video using RockWool fantastic Idea.

Very cool build! I hope you run it for like 8 hours or more straight to really test it.

ty for this

Very informative 👍

Nice job. Thanks for sharing. I like the motorcycle muffler. Good idea. I saw a guy who used an RV muffler. It’s odd that the rock wool made you it’s because it is not a fiberglass product . But I guess we all have different sensitivities

From what I have heard about those sheds is to make sure you paint them with a great UV exterior paint to make the last longer in the sun. One complaint is they get brittle if not painted.

I love this and will no doubt be using it eventually the way things are going, could you possibly do a video on home scale Biodegesters? they seem like a brilliant tool for Preppers as they produce no smoke or sound and only need waste streams as fuel.

For good ventilation, the general rule of thumb is to have twice the area of passive INTAKE as you have ACTIVE exhaust. You can either do the math on making one hole, or (the simpler way) if you cut a 4" circular hole for the exhaust fan, cut two 4" circular holes for the passive intakes. (The shape isn't important. Just the area of the holes in respect to one another.)

Love this proof of concept. Do you think anymore bafles in the intake and exhaust boxes would make any significant improvements. Also the exhaust needs to be lower sound the sound is not projecting out into the area. If you are using this during a grid down type issue its going to be a lot quiter in your neighborhood .

I live in bartlett and would love to come take a closer look at your setup

My husband made a similar setup for our tri-fuel generator but instead of a blast gate he used pvc pipe and a screw-on pvc cap for when it's not being used.

you can use a prc drain cover thing (not sure what it is really called but it has a hole and is surrounded by materia, square with a round hole with slats). It lets you seal the hole and prevent critters from climbing in...easily attached to unit with adhesive. as others have said, don't seal the bottom.

I'd also add seals on all the doors/lid - anywhere air can escape, so will sound.

I’ve thought about building those baffle boxes into the interior. Seems like there’s enough space and might be able to make more turns and cut more DBs off

I have a dozen comments and suggestions, however, I won't bore you with my opinions. You showed a beginning decibel reading (79.6dba), was there a completed decibel reading? Considering, plastic, wood, and foam are all combustible materials, using *Rockwool insulation was a great choice! I use the same brand (different variations) in my house, garage, attic, and generator shed. In combination with my solar/battery storage backup system, I use two 2500-watt dual-fuel generators with a combiner box connected to our 250-gal. bulk propane tank with a factory dba rating of 53dba. Inclosed is about 45dba. "Rural Prepping" 🤠

If you’re looking to really sound proof something, look into mass loaded vinyl. It’s what movie theaters use to make a room truly sound proof. The thicker it is, the more exponentially sound will be deafened. Air is the #1 reason sound will get though so it might be smart to build an additional box around the generator, inside the shed. Then wrapping mass loaded vinyl insides both boxes. I guarantee it would be

I can run my generator in the rain now! Thank you

Nice

Great video! This is exactly what I need. Wanna build one with me while you’re in town? HaHa…

Nicely Done. I wonder if you put baffles inside of the boxes, if it wouldn't cut the sound down even more?
