Title: DIY Shelf Dampener Mod
Post by: Pacifist on Mon, 23 December 2013, 22:53:45: So I decided to mod my keycool 84 with shelf liner to make it more quiet. After the mod the board is significantly quieter.

First layer of liner:

Just cut it out and put it on there

Cutting holes

Just cut holes for the pegs and the USB cable

Add more in the gaps

Second layer

Didn't cut out room for the USB port and just made slits for the cables

Its wayyy quieter now. A lot less ping. Now I just need to stop bottoming out every stroke.

Deserves recognition.

Thanks! I found out about this from Photoelectric and some other people here on GH.

One 60 inch by 12 inch mat is enough for a 75% board, a full size, a 122 key board, and I still have 24 inches left.

It does increase weight but by not that much :))

I've done this mod to both the plate mounted KC84 and the PCB mounted G80-11900, and the difference is about the same. There is more ping reduction in the plate mounted board because the ping bounces around more but its much quieter on the PCB mounted one.

I have upgraded to EPDM roofing membrane, but that is harder to find.

They will be posted in the Classifieds.
