Roy Regamey: Hi Guys. You are probably wondering why I have not emailed out the plans
for the box I built. The reason I built the box in the first place was to
use while building my new house and that has been keeping me very busy. I
get a lot of request and the problem is I don't want to spend the rest of
my life emailing people box plans. If anyone has any ideas of or thoughts
please let me know. One person suggested that I set up a link and charge a
small fee. Any feed back would be appreciated.
3beltwesty: The Champion Generator 46595 is 68dB at 23 ft according to its specs:
Lowes and Home Depot has sold many of these units.
0:30 Fuel Tank Moved up : Roy here has the 3.8 Gallon Yellow stock fuel
tank moved upward about 11 inches for ease of refueling. Normally the tank
is right behind the Champion logo. Thus the Yellow fuel tank is mounted to
the outer top box and a longer fuel hose used to connect to the carb. An
exploded view of the generator is on page 19 of the manual below.
Here is the manual for this generator:
0:30 Thermometer is seen in the lower right of the inner box. It looks like
a simple kitchen type.
1:11 Duplex Plug is 120 volts since this is a 120 volt only alternator
The 46595 Champion is rated for 3000 watts at 120 volts and 3500 watts
Roy's generator has a low oil shutdown sensor that kills the engine if the
oil level is too low.
This generator has 2 brushes on the rotor for the field current. An AVR
(automatic voltage regulator ) is on this unit . The AVR is sensing the
stator coils output voltage and adjusting the field current to the brushes
that connect to the rotor. This scheme makes the sensed impedance at the AC
socket to be lower than with a non AVR unit. This means that at light to
medium loads the voltage will be closer to 120 volts. With a heavy load the
field can be fully on and the output voltage drops way more. If one plots
voltage versus amps "used" there will often be a break were the AVR is
saturated; ie ran out of poop.
This video shows one of the better sound reducing cabinets. It has a box
within a box with distance between them. This is required since at least
one half the noise is NOT from the muffler area. That noise is from the
3600 rpm engine; ie 60 revs per second and the plug fires 30 times per
Trying to reduce low frequency noise at 30, 60 and 120 Hz etc requires
thickness, dampening, walls ( the two boxes) not to be connected by much.
A homemade enclosure requires one does not overheat the generator, thus
fans and vents. A massive concern is fire; thus to all be carefull and do
not burn down your house.
Davy Chinkatok: Nice, sound proof box you have there............like it 😄😄😄😄😄😄
Screww Googlle: Impressive results.
Jim East: Great job, I would have put something on the outside to read the temp.
inside the box. I assume, relocating the gas tank was for convenience of
fueling. I bought 35 of these Champion ( I think 6500's ) generators during
hurricane IKE to install on my customers a/c condensing unit so they would
have a/c in the house. After that storm, many HOA' s put heavy noise
restrictions in place that address generator noise. As for the comment
about purchasing quieter generators, most people make this type of
purchase when the need is great and supplies are low, therefore selection
is poor. Please email if you decide to share your plans. thank you.
XboobtubeX: I guess I will never understand why people do not just buy a quiet
generator from the start. Then no box is needed. Honda eu6500is. Best there
is. And the quietest straight from the factory.
mike grubmiller: put a gen in a shed once in 30 minutes it was to hot to stand not to
mention the fumes
Peter Gizmos: This thing works great, good job!
Darin Teichmer: Roy, did y you ever put these plans out somewhere? I would really like to
get a hold of them.
Byron Moore: Hey there Roy great video i been trying to find something just like this
been trying to find a way to make my gen quit while at deer camp or just at
a camp sight so i don't disturb anyone i am welling to buy the plains from
Thank you for sharing this video
Jeff Gardner: Normally I would never say this about a youtube video, but if you could
talk during video it would put the quietness in perspective. I also would
never choke a gen with a muffler other than what came with it. The quietest
gens have extra horsepower just to overcome the restrictive muffler. Thanks
for posting, sorry but I'm always inventing a better mousetrap. I once
worked on Peter Framtons tour buss, I asked was it plugged in? They said
the gen is running. OMG! I heard zero. Just think of a brand new honda
civic at idle.
You could run that thing during a funeral.
Kristen Lee: did you share the plans for how to make this, whether it is for a fee or
not, i too am interested...
Sean Williams: The only problem I see with that is that it's no longer a "portable"
generator! But it sure does cut down on noise!
Eric Kimminau: What kind of muffler did you put on on there? Ive been researching. Looks
like a motorcycle muffler.
bcvonnie: Very nice! Looks good and not over done, good job.
Brad Emerson: very nice
richard haus: Roy, if you are sharing plans i would be interested also. Easiest way to
share is get a free "Dropbox" or "Box" account and share the link.
PacificNorthWestPrepper: This is the BEST video I've seen regarding soundproofing for a generator!
Very nice job! As for getting plans out to those who asked and even making
some money off your efforts, as a online marketer myself, I'd be open to
offering advice on how to go about it if interested! Again..GREAT VIDEO!
Like Winning the Lottery - How moving to the Philippines made me happier than a millionaire": Wow! This is great for what we are doing at our house.
Kenneth Bergee: Nice job. I would pay a fee for drawings.
Piranhaxz: Reference to sharing your plans !!! Just add still pictures of your plans
at the end of this video .. Or just video the plans either way ..
Everyone can look at them this way .. Thanks
Bob Arritola: Do you have the design posted somewhere for download?
vwfiero: I saw the cfm and size in description did you have two on push and one
Bob Arritola: I like your design, and would like more info so I can build my own.
vwfiero: What fans did you run. What size and cfm? Thanks
urgentcareguy3: It looks like everyone is sending you for plans. Are you still sharing
them? You might like my channel.
David Chandler: this is really effective. I was thining of studio foam. It quiets my
horrible drumming. The birds chirping outside is louder. That aside I am
worried a bit about heat.
ExiledDespot: If you aren't afraid of adding more weight, you should consider lining it
with lead. That'll help reduce the low frequency noise
Al Ruark: Hello Roy, what you built is a little unique in the sense that it was
built around a Champion generator, if I'm viewing the video right it looks
like you raised the gas tank up which is a good idea so you can fill the
tank without opening the bottom door panel, the main problem I see is that
some of the gen's out there would have a different configuration meaning on
your video the exhaust is coming out of the box from the rear, I have two
gen's one is a generac 6500 and a harbor frieght 7000 and the exhaust on
both are coming out of the right side, and I have seen some that come out
of the changing the oil & plus front, also can you remove yours from the
box without to much trouble? if not I would think about putting the gen on
some sort of slide out so you can work on the gen,Charging is a good idea
it's worth it for people who need some help, Hope this helps
Restie Antoni: John_restie@hotmail.com. Would love to have the plan as well. Many thanks
spacecalander: Awesome, i have the same one and the campground i have been going to for 4
years says i cant run it any more due to the noise. Is the box easy to
babzog: Agh, these little keyboards! Would live a copy of the plans!
firstname.lastname@example.org. Many thanks!
youwindogs: Hi Roy, Just found your video, Exellent noise reduction! Can you share the
plans? Thank you. I have a loud gas air compressor and been trying to
silence it for while.
Eric Baker: Hi Roy Best box I have seen up to now that's for sure, can I get a copy of
your plans please. Thank you. email@example.com
Posh Jesscott: same here man. This is a pretty good layout you have. If you have time to
share with more people or if anyone here has had success getting it, can
someone hook me up?
seacliffer: this is the best one I have seen so far. Could you share your plans with me
firstname.lastname@example.org what materials did you use for the walls to dampen
the sound? thanks
bckress: Hi Roy, I see you have a lot of requests for the plans. I am very
interested in this because I have the same generator and it's so loud.
Would you be able to send me the plans too? Thank you!!!
NarraRick: Good work mate ! this is the best one I have seen so far on youtube!!!! All
the other may as well not have any enclosure , I can’t believe how much
your box lowers the sound :} awesome !!!!
Roy Regamey: The box is very heavy. (MDF) Inside Not that portable. I do have it on
wheels. I didn't build it to be portable. My main concern was for the noise.
Scott Donaldson: I also would like the plans please. Thanks email@example.com
tudunka1: A rought sketch would be great. I have an 8750w that is just LOUD and I
would like to muffle it down and you plan seems to work just great. I
understand that I would have to scale to fit mine, but it seems you did a
great job. Thanks.
Loyd Perrymore: I just bought the exact generator in the box. This is the best sound
proofing I've seen. I'd love to have the plans. firstname.lastname@example.org
tudunka1: Hi Roy - This is very nice and I'm surprised on how much the sound is down.
Do you have a plan you can share?
rustylocke1: Invader92@live.com would love a set of plans and would be happy to pay for
them if the price is right.
Stephen Hartwell: Hi Roy, can you send a copy of the plans and materials list?
babzog: Would love to have a copy
Daryl Beaver: email@example.com , I would also love to have your plans on how to
