June 2011 – Bulkheads

11 June 2011 – After another few discussions with some experienced Canardians familiar with the old glory days of the Cafe Races, I decided on another modification.  Now I’m sure this  may very well elicit some groans and ha-rumphs, and maybe even a few mutterings of how crazy I am, to put it politely, but I decided I was going pulley-less and running my rudder cables from Point-A (the rudder pedals) through a curved conduit that traverses through the centersection spar, makes a semi-shallow bend and heads to Point B (the rudders).  No fiberglass strands will be hurt in the making of this modification, just merely slightly separated at the holes in the foam so that glass strength and integrity is still in tact on the centersection spar.  So, no pulleys means that I don’t require the pulley brackets, and thus no “ears” on the firewall.

Modified Firewall

Once I finished cutting the ears off the firewall, I could get to glassing it (and laying up CF on the instrument panel).

12 June 2011 — Ok, obviously by just that fact that I’m building an “experimental” airplane I like to experiment, at least a bit.  I thought quite a lot on how I wanted my instrument panel to look.  I wasn’t sure exactly, but I figured I would make the top layer Carbon Fiber on the front face of the panel to A) Add stiffness and B) Add coolness.  I ordered some CF in my last Aircraft Spruce order and after it came in, I assessed it one last time and decided to pull the trigger!

Project Update

Hey Guys,

I’m happy to report that the install of all the internal CF baffles is complete, including the final gap fills around the edges to ensure minimal air leakage. 

As I’ve noted previously, all the exhaust pipes have been welded, with the required trimming of all the exhaust pipes to length coming soon.  I’ll caveat the exhaust pipe effort with the fact that I may need some welding on the ends of these pipes to get them pointed in the right direction, but I’m of course hoping not.  In addition, I have 2 compression style EGT probes from GRT on hand and will need to have the stainless steel threaded bungs welded to the exhaust pipes to mount those specific probes.

The convergence of a few intertwined components I spoke of before is STILL slowly coming to fruition, which will set me up to be nearly done with the entire engine install, sans the firewall (at this time).  With the CF inner baffles now installed, I can turn my focus on finalizing the aft lower side of the engine aluminum baffle install.  That will, in turn, allow me to identify where the bottom cowl cross rib baffle/stiffener needs to get glassed into place.

I’m still intent to focus solely on the plane for the next however long it takes to finish this bird… ASAP!
