Marv -
   I been reading all of the comments regarding compression of
fiberfrax/SS when tightening the engine mounting bolts. The construction
manual I used acknowledged this and noted that the fiberfrax could be
relieved locally (by hand, using a 2" hole saw) in order to install two
7/16" area washers under the engine mount pads. The washers are exactly
the right size and worked just fine! Why  would anyone do it
differently? The only valid comment modifying this approach was using a
2"circular piece of 1/4" phenolic in lieu of two washers...for weight
savings. Any weight saving would be minimal and I'd personally feel
better having steel washers there vs. phenolic.  Well, HOW DO YOU LIKE
MY EXCELLENT FORMATTING NOW!!! All I had to do was to type full lines
and let the software auto-format. Send me your U.S. mail address and
I'll send some nice photos of my plane and engine installation.

[I guess I missed the comment in the manual about the area washers, but I
like the phenolic idea, personally, also the idea of waiting until the
entire firewall layout can be planned and then prep all the holes similarly
as required.  

Your formatting looks great now, and my address is 209 Labelle Ave., Fort
Myers, FL, 33905-2521.  I'll upload whatever photos you send to the LML
Attachments area... thanks for the offer.  <M>]
