Paul,
I have a bed type mount from Lancair that uses the larger 3-1/4" dia.

Lord mount.  Hole size is approx. 2".  The largest dia. available from
McMaster Carr appears to be too small.  Do you know of any other sources for
a "reasonably priced" mount?  I have exhausted all my sources. Mark

Get the Barry Controls catalog called "Engineered Solutions for Controlling
Shock and Vibration".  On page 57 they sell neoprene rubber blocks in the

sizes

you need. 3.15 diameter up to 5 inches high roughly in 1/4 inch increments.
The hole diameter is .83 inches. If you freeze it you might be able to bore
it out to two inches on a lathe.

Barry Controls 1 (800) 227 7962 or search for their web site.

The other thing you can do is get some 1/8 inch thick silicone rubber sheet

>from McMaster or AC spruce and cut out a bunch of rubber washers and glue

them together with red RTV. It is working for Chuck Dunlap

Paul,
I know the barry mounts are the go! However have you, or anyone,
considered the Devcon Flexane castable Urethane, shore hardness
ranging from Shore A60 to A94. It's been around for a long time now
and if memory serves me right someone suggested that this be used
in the different torque pulse dampeners on PSRUs. Apparently it has
been used with much success. It may not be as good as the Barry
Mounts, but I'm wondering if it might be an option in this case.
Just a suggestion !
