I remember reading a book on soundproofing when I was a kid. And they said the best way was to build a room inside of a room. Look at how quiet your little setup is, imagine if that little setup was inside a tool shed. Obviously you don't need it that quiet, these people were making recording studios

@@DaedalusHelios Good point! I have almost finished fine tuning my shed, a Suncast BMS4700 that houses a WGen 12K DF generator. I am no engineer or had any experience building or modifying something for a specific purpose. I did go to Lowe’s & Home Depot and bought large L-brackets and attached them to all of the shed walls and installed the foot of them through the shed floor into a 6” slab with concrete bolts all around the bottom of the shed walls. Also purchase two steel beams cut to the width of the inside of the lt and rt walls to reinforce the rigidity of the walls. Thinking of reinforcing the corners that join the rear walls to the side walls as well in a vertical way if that makes sense ( after all not a engineer here) So just had a freeze here in San Antonio and so far so good.!

I'd like to see screen/rough mesh on your outside wooden box! If wasps build in that, their nest will obstruct airflow...🇺🇸 😎👍☕

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.

@ArthurDentZaphodBeeb

Nope, that's only when you're worried about rot - plastic doesn't rot, so caulking entirely around the opening is the proper thing to do. This is an attempt at a sound-proof container - anywhere air can escape, so can sound.

@missyjo2475

Жыл бұрын

I'm sorry but moister and moisture are two different things.

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

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.

@karryhardman8735

The alternator windings will quickly fail at about 150f depending on the Ins class rating. So any heat the alternator makes will be on top of the inside of box temp.

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

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

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!

Try building and adding an intake muffler to your compressor. A lot of the noise come from the intake. I did this myself and it was considerably quieter. Many videos on YT showing different methods.

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.

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!

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

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.

Hey thank you for making this video you are the best

Awesome build

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

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.

This is genius. 💫

Two things in a generator that hate heat; heads and generator windings. If you have 200F inside that compartment you have a recipe for disaster. Look for a 10-15F rise. I can see right away your fan is undersized. For me to achieve the desired temp; rise I went for a 16" AC infinity 3000 cfm fan. Sarted out at 12" 850 cfm and inside was over 125F. Another issue you have is the escape area on your compartment hoods appears to be smaller than the fan exit area opening in the compartment wall. My generator is a 5kw Honda. Yes you need to keep the propane outside the compartment. When installing insulation consider ïnsulation pins which you can find on Amzn. Saves drilling holes thro the walls.

Well done!

Great video - thanks!

Great work

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.

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 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.

Very good video! Thank you...🇺🇸 😎👍☕

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.)

Great idea.

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

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 .

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.

Great show kris

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" 🤠

My neighbor has a generator and he lives 1/4 mile away and I know immediately when he cranks it. Must be one of the open frame types.

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

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.

Nicely done! If you ever get a chance, have a look at a film set mobile generator, might give you some idea's for another build or upgrades. Expanded metal/perforated metal covering your insulation will give it support, a blower fan blowing into your air intake area will aid in cooling ... just a couple ideas. Great job otherwise, cheers!

Thank you!
