[GreenKeys] More Re: Sound Deadening

[Dave Hunter]

Hi All:

A couple of weeks ago, I started a thread about replacing 
the sound felt pads in my Model 15 teletype. These has 
largely disintegrated, and someone in the past (perhaps a 
relative of MacGuyver) had taped it together as much as he 
could using duct tape.

Finally my search led me to Ebay item # 150637154645 a 
sound deadening closed cell foam product sold for car sound 
insulation. I am told this is also used for noise deadening 
in aircraft.

It arrived today, and has worked very well. The old felt 
blankets peeled off easier that expected, and this new 
sound insulation stuck very well using its peel off 
backing. I used the old felt pads as a template to cut the 
new soundproofing. The entire process of removing what was 
left of the old insulation, cleaning, and replacement of 
the pads took about 1/2 hour...

The end result is a machine which is about 30% quieter than 
before, and which doesn't bind when put on the teletype due 
to the old insulation which was ripped and coming loose in 
many places. The 4 sheets bought for $11.95 CDN in the 
auction were just enough to do the job, and I have a few 
smaller scraps left over.
