The Murphy Builders Site

Hi all,
Hoping to promote some discussion which might help enliven things on
the site and help some builders........... like me.
I have the cabin roof in place, drilled and cleco'd to the top carry
through FUS 3 only. I need to do some aligning of bulkhead and root rib
flanges to make a nice job of it. Possibly joggling the bulkhead flanges at
the root rib will help.
I'm sure I'll sort it out but has anyone any advise that might assist?
I'd be grateful. Any comments on the cabin roof generally would also be
gratefully received.
A bit further on is fitting the rear wing attach brackets, sandwiched
between two bulkheads. There has been discussion in the past about leaving
the positioning of the brackets until the wing is being fitted so the angle
of incidence can be set correctly. This makes sense to me. Does anyone have
a comment on this?
Cheers and thanks, keep up the good work Mike

Hi Mike,

Here are a couple notes and pictures of my cabin roof work in case anything
here might be helpful. Note the liberal tape usage to hold things down
before drilling holes.

I'm not sure I even read other advice about holding off putting in the rear
wing attach brackets, but I wasn't brave enough to do it before wing rigging
(which I've still not done). I did however, stack up the brackets,
sandwhiched them between the two bulkheads and made careful placement
measurements so that I could cut the slots for them to stick out of Fus-27.
This allowed me to finish off the rear "float fix doubler bulletin" in that area,
and basically, it's all ready for final bracket hole drilling when I eventually get
to wing rigging.
Cheers,
-Ben, 496R

Thanks for all of that Ben,
Looks like you are doing a nice job from the photos. Your input has
helped get me back on track. Cabin roof is cleco'd in place and just
started work on the corner wrap Fus 70 ( I think) behind.
Fixing the rear wing attach at the rigging stage seems the go.
Cheers and thanks Mike
