Just a note, I have since made a better hood that incorporates the exhaust and air exit. We designed and fabricated a filter unit that goes under the unit (covers the battery and drain holes). It stops ants! I will add some pictures of it tomorrow. I will be selling them if anyone is...

I didn't get my silicon boots in today, but when I do I will show how they are attached and hopefully they will take care of the 95 db sound leak around the muffler exit hole. I will take the unit off the skid and fix the bottom drain holes. The stall mat is not nearly as efficient as the open...

Some more modification pics I modified the front tool storage box to allow for more airflow and I put sound materials and padded the box to prevent rattles. I added 1/8" screen behind the intakes. I used wire ties to secure. I did a sound test and even with the wind we were ambient...

MEP-803A Specs: Sound level: 70 dBA at 7 m / 23 feet at rated load (I found this interesting) I will crank it once I get to work and measure at 1 meter and also at the 7 meter distance today. Next things to try!!!! I will pick up another stall mat this morning and see what difference it...

I took the hood off and put some OC 703 in using 3M 94 spray adhesive. The other 2 pics show where I filled around the latch and in the open door edges with butyl rope caulk. I was told that a clear rubberized coating might be good over the face of the fiberglass to keep if from...

It is about 5 db quieter than it was. The mods to keep crap out of the radiator increased the sound on the side but I managed to contain it so I am very happy. The great thing is it is not loud at all above the generator like it was. You could easily hear the generator in the second floor...

I assembled the box and did a sound test. Sides - 69 db at 3 yards (79 db @ 1 inch) Front - 72 db at 3 yards (84 db @ 1 inch) Top - 78 db < 1 yard (82 db @ 1 inch) Rear ( new exhaust hood ) 75 db at 3 yards. Note! before I added the new exhaust hood I was reading around 98 db <...

Had other work get in the way so I had to wait a few days to get back on this. Everything I sprayed is fully cured now and dead to thumping! Might as well thump a rock. I will reassemble the cabinet and test it today. Once I have the new readings I will see if more noise controls need to be...

Well everything is in the oven and curing. Got lucky and found a very large 4' x 6' x 5' Styrofoam lined cardboard box. I put all the sprayed parts in it with a small electric radiator heater to keep it warm. So far so good. It is just 75 in the box so everything should cure without evenly...

I just use calipers and a micrometer.

checked with the vendor and the kero heater is npt a problem. Just have to keep the the room above 50 for 24 hours min. 7 days to fully cure. I checked and I am 1 mm too thin so I will apply another coat. It is hard to tell how thick you are applying since an undercoating gun creates a lot...

Well I got the second and third spray coat done today. I had hydraulic project get in the way of doing more. It was 34 degrees in the shop and I had a torpedo heater trying to heat my spray booth so I ran the heater for 5 hours and left out at 6:30 tonight. I did get the OC 703 ordered and I...

Well you can spray your truck with gloss for parades and shows then peel it off when you want flat drab paint again. It should look nice and new!

Well I didn't get the idea from dip your car but I did see a cop show episode where there was a robbery and the people painted the car blue with plastic dip and were peeling it off when they got caught. I didn't know this stuff came in so many options, cool , I will have to get some HyperShift...

I clean with acetone before I use paint of coat. It is funny stuff, you have to shake it up really good. Like you, I always had better results when dipping. When I spoke with the gentleman in the video we went back and forth about cost vs. gain. I guess I could just use a rust inhibitor...

I just put a small piece if butyl dampener on the frame behind each lifting ring. I still coat all of my hooks and rings with plastic dip. I also coat the first 10 feet of my winch cables with it. I had the following polymers company recommend plastic dip to me for small jobs like this as it...

The vibration mounts look brand new! No issues with them. Put silicon on the rubber parts. I will have to mock up the pattern you suggested in the fiber board. There is very little room directly above the muffler. Maybe an inch. I added a steel stiffener since the cabinet dips there and...

Hi Tim, I agree with where you are going with structural enclosures but for my requirements I only have the space allocated inside the unit to work with. I want it as quite as possible and I will add some sound absorbing material next. My goal is to not increase the sound, lower it if...

I just looked a a home movie theater install that stated the cost @$2 a square ft for 1200 sq ft. It must be decoupled with special spacers in order for it to vibrate with sound waves to convert the sound into energy. If you could make a box to cover the entire generator you would never hear...

Hi Ahab, Looked into it and the Navy touts the material to be equal to 12" of poured concrete. They also allowed a commercial company to produce it for commercial use. Well I found the same specs and 12" claim on a NASA spin off company named Acoustiblok and they are located in FL...
