The Murphy Builders Site

Hi Richard !

Others have covered the FUS-30 doubler - I would just order an
extra from the factory, because of the bends....

It's hard to tell about your firewall position from the pics on
Barnstormers, but it does look like it was moved back 3" --- but this
necessitates a steel "shelf" sticking out from the top of the firewall
to fill in under the windshield - which is not in the pics ....
Sorry, don't have a measurement for reference .... If you can
post a side view pic, it would be easier to tell.

There's nothing to worry about if it wasn't moved - most builders
today do not move it back, regardless of engine. This gives a much
wider range of engine choices .... If it was moved, you are stuck
with an O-320 or similar (O-290 is not a good choice - haven't been
made since about 1954, and parts are 5 times the price of O-320
parts !! Also, often slightly heavier than O-320's ... and more
prone to valve problems ... :-( )

The rivet gun is used stock - the modified rivet gun trick only
applies to Zenith kits - because they use a different rivet style
& technique.

Builders:

I sent a email to MAM on Monday with a couple of questions, but I haven't
heard back yet.

Is the tail wrap modification a piece that can be ordered from MAM, or is
it
only a builder-developed item out of scratch 0.032?

The project I have has only pictorial documentation and I can't readily
tell
what the original builder intended on engine size. Is there a couple of
measurements that can be taken to determine if it is "stock", or if it is
instead built for the heavier O290/O320? I'm sure there is a solution by
back-tracking through the plans, but to be honest I get lost at trying to
do
that. I'm thinking something simple like the forward edge of the bottom
thick plate (SG-13 ?) to the bottom of the firewall.

Does the nose piece for the riveter need to be modified for the Rebel, or

does one just use the riveter as it comes from the factory?

Thanks again,
Richard
