[NSRCA-discussion] Vibration Dampening mounts

[Woodward, Jim (US SSA)]

Guys - thanks for the replies.  I chose to purchase this from McMaster
Carr:
http://www.mcmaster.com/nav/enter.asp?partnum=9213K11&pagenum=1350

 

The price was the major determining factor - something like $1.87 versus
$4.00'ish each.

 

Thanks,

Jim

I've successfully used the well nuts (blind rivets) to attach motor
mounts to the firewall. Work great and much easier than captive nuts.
Piedmont models used to have an app note on their web site with the
ordering info.

Jim,

 What you're looking for is commonly known as an "isolation" mount. Take
a look here:

http://www.rubber-group.com/isolationmounts.html

I don't know what their minimum quantity requirement is but it looks
like they have just about any size. Let me know if you have any success
with them.

 

For pipe mounting I've been using a different type of mount lately. It's
called a "well nut" or "rivet nut":

http://www.mcmaster.com/nav/enter.asp?pagenum=3214
<http://www.mcmaster.com/nav/enter.asp?pagenum=3214> 

It's a piece of threaded metal encapsulated in rubber. You drill a hole
in the hard-point, insert the well nut, attach your part to the well nut
using a screw and tighten the screw. The well nut swells up on the other
side of the attachment point and retains the part that you're fastening.
It's self locking and you can control the amount of isolation by how
much you tighten the screw. I've had iso-mounts fail (the two halves
will separate) but the well nuts hold up fine. I would suggest replacing
them during your annual maintenance though - I consider them a wear item
like fuel tubing. You can add nylon spacers of different thickness'
between the well nut and the pipe mount to align the pipe too.

	http://www.vibrationmounts.com/Store.asp?Page=Products1.htm here
is a

I'm
	having trouble finding them with 6/32 threads, and available for
sale.
	McMaster Carr calls them "Vibration Dampening pads" but does not
have a
	small enough size. 
	
	Does anyone have a reasonable source for these? I have found
them to be
	about $7.00 EACH from stores that published prices.
	
	Thanks,
	Jim W.
