well I've got another project on starting this is my generator and I've
run it a few times and boy is it loud and I'll tell you when you're the only
one in your neighborhood that's got lights and power and heat and can cook
food it's sort of attracts people you don't really care to have around your
house in a situation where you've got no lights
not to mention that where I live in Louisiana a lot of storms come through
here and people get their generators stolen there's been all kinds of methods
and the sneakiest one is uh they'll roll a lawn mower up beside your generator
running at night and they'll shut your generator off leave the lawnmower
running and then carry out your generator and most of the time it's your
own lawn better Lumbo or that they're tricking you with anyway I've decided to
try to quiet this generator down so I took a few panels off and I figured out
a way to mount a muffler over here I'm going to put it I'm going to take this
muffler off and I'm going to make a flange to fit over this here and I'm
going to put a 90 on it and come out here and I've got this muffler here that
I'm going to to mount right here I'm going to make some you points you you
bolts out of some threaded rod and bolt this up but before I do all this I have
a decibel meter on my wife's phone and I'm going to run this beside the house
where I usually run it and with a without this muffler with the original
muffler and then I'm going to bolt this up and put it in the same place and run
it and check a decibel meter and just see how much quieter it is I know it
will be quieter I don't know how much I also heard that
you can extend this the end this muffler the exhaust the outlet up and if you aim
the exhaust straight up that it tends to diffuse the exhaust noise somewhat and
people can't pinpoint exactly where it's coming from
so when I get to the point where I've got this ready to be mounted and a 90
made up for that over there and a means of connecting it all to that end I'll
have to have several pieces of reducing hardware and maybe even some flex pipe I
don't know yet I'm just doing this trial by error but we kind of need to see how
much it quiets it quite sit down look keep you posted well I decided to go a
slightly different route I was going to remove this month ler and then take off
from here and go over to the other side of the generator but this actually
required less parts and plumbing and it was cheaper I only got like 60 bucks
into this all tote a welded flange on to the original muffler you bolted this
flexible aluminized exhaust hose here
the brackets that I built it on there and I had to do this because the engine
is mounted on rubber feet and when the engine moves and vibrates the muffler
has to move with it or else it would break something you know somewhere the
weak the weakest part of the muffler system somewhere it would crack so got
the hose got this muffler you bolted on and I welded the muffler onto those
brackets and I thought about whether I should weld it or are you bolt it but
you know if I ever need to remove it I could just unbolt the brackets that I've
got pulled into the engine that was simple and easy to get to
well I've ran this before and after and I'm really impressed even with just a
cherry bomb' muffler you would not believe the difference in noise level
the decibel level from 10 feet away was 94 95 decibels unbelievably loud really
annoying actually and since I put this muffler on the decibel levels 85 that's
a pretty big difference it's a big enough difference that I can actually
hear the generator head whirring making a whirring noise you know we're and I
can hear the rocker on the valve train and the rockers you know clicking and
ticking kind of interesting it's that quiet and I'm going to go one step
further I'm going to build a soundproof shed just large enough to wheel this in
to put some ventilation in it with maybe a small fan or something I got another
piece of this flexible pipe that I will eventually plumb this to the outside of
the shed that I'm going to make so that will just you know the exhaust will just
come right outside of the a little generator shed and you
shouldn't be able to hear this thing till you just walk right up on it
because where I plan on putting it well I'll have to show you that it's it is
just freezing freezing cold out and rain in and remember terrible weather here in
North Louisiana anyway I'll show you that shade when I get around to it but
I'm going to go ahead and put this one up see
