Lightbulb Dampening side cover noise.

I decided to do a little experimentation and pass this along. My build is torn down and hopefully I will be painting this weekend. Here is what I did to dampen the "forks in the blender".

Needed: cheap latex caulk, plastic wrap, 2 stroke China girl, minimal artistic ability.

I began the process by putting down a layer of caulk to coat the inside of the side cover.

Next I put a sheet of plastic wrap over the motor.

With a little care I seated the cover in place to check for interference impressions in the calk (you'll need to actuate the clutch lever to get an accurate imprint).

After removing the cover I could see the caulk was heavy toward the center of the cover so I used a jar lid to press it out and continued with my fingers and thumbs to form the caulk to better suit the mechanicals. It is easy to manipulate the caulk as it is now under the plastic wrap which should should transfer off the motor and stick to the side cover.

In a final preparation step I actually mounted the cover, plastic film, and caulk to the motor with two screws. I then rotated the clutch shaft while the lever was depressed to squish any remaining caulk out of the way.

After removing the cover I placed everything in the freezer to stiffen the caulk. After an hour or so the plastic wrap peeled out leaving the nicely formed latex in place. I have it curing right now and will have a few days while I paint to let it skin up and start hardening a little. I will test it's effectiveness in a week or so.

Fairly in-genie-us!

Should dampen nicely.

K.I.P,
Please let us know how it works for you. My only concern would be the adhesion to the cover. That could make a real mess if the latex comes loose. Keep us informed.

i'm still claiming Plasti-Dip spray paint is the way to go.

I mean, c'mon, their slogan is "It's like duct tape in a can!"

If they had also said like ty-raps, bailing wire and dry wall screws I would have run out and bought some Plasti Dip myself!

Agreed, adhesion is a valid concern. However I have used this stuff around the house and removing it (or caulk in general) can be a chore so I figure I have a good shot at success. I also agree it could cause a mess but not really a damaging one, if it breaks down or comes loose it won't destroy anything, a potential nuisance more than anything else. Time will tell. In retrospect I probably should have scored and roughed up the inside of the case, hindsight is 20/20. I will try to update this in a few weeks, we are still getting out of winter weather here.

Do the same, but use butyl caulking. It will stick to grease!

I always have scrap elk hide around from making moccasins. Cut it to size and then adhere it with shoemaker's contact cement (what I use to adhere rubber soles to my mocs. Good stuff.

I bet that would be great for using between the mounts and the frame too.
