Title: Doubled Shelf Liner for Added Dampening
Post by: aref on Mon, 24 March 2014, 17:58:01
GH suggested I use shelf liner to dampen the ping in my CMQFR. I did it and it worked well; but I wanted a tad more dampening. So I added a second layer of shelf line on the base layer of the case except under the R1 space-bar row, there's too little headroom for adding a second layer under the space-bar row. The result is excellent. The keys, MX Blue, sound thocky and feel great. And the additional shelf line didn't prevent the case from closing properly. All it did was super dampen the CMQFR's interior. I'm sure many of you have done this, but I hadn't read anything about it, so I figured I'd post it.

After Pacifist's comment (below), I measured the thickness of the liner I used: 1/10" thick for a single layer.

It depends on how thick your liner is

stuff as much as you can

Yeah. Just stuff as much as you can. Don't worry about if you've having trouble closing it. The screws will pull it altogether. Also, stuff some under the top as well. And stuff some more around the switches before you put the caps back on.

Good point. I just measured the thickness of the liner I used and it came in a 1/10 of an inch. The difference in the sound of the key switches and dampening is incredible.

Alternating the waffle rubber mats with felt can work well, too.

And for those odd-shaped spaces, strips of felt rolled into appropriate-sized cylinders can be nice, and look good, too.

Good ideas. I had cut oddly shaped pieces of shelf liner to fill those odd spaces inside the case.
The interior liner I did may not be aesthetically pleasing, but it sure works great. Thanks for the
space-filling ideas.
