Fellow canardians,
I am relocating my ship's brake master cylinders and installing them behind Dale Martin's rudder pedals.
I am also upgrading the ship's engine to an IO-320.
The Long EZ plans call for the original plans brake cylinders to be connected
between the aluminum engine mounts on the firewall.
The lower mount carried the end of the brake master cylinder through a bracket-CS73, while the top anchored a lever-bellcrank, which converted brake pedal motion into a "push" on the brake cylinder actuator.
Doing this mod on my Long-EZ, leaves an unused 3/16" hole in the aluminum "L" angle extrusions at (as a bonafide COZY mk.4 builder flyer suggests) near their point of max bending - not a desirable trait in an engine mount.
Has anyone ever heard of a fix to get rid of this hole without doing
major surgery on the extrusions, essentially replacing them?
Filling the hole with a weld will probably conduct heat to the nearby
spar and anneal the aluminum mount.
Reinforcing it with an attached piece of aluminum relies too
heavily of the attachment method of the reinforcement piece - epoxy?
rivets? (more holes).
My instinct says reattach the "old plans" bracket, without its associated brake master cylinder with its "old" countersunk screw.
Any ideas welcome.
