Here are some shots of the motor mount and related brackets. You can see I added .125 aluminum angle
to the outside of the top motor mount rail. Notice there are three AN3 bolts to tie this into the
lower plywood shelf. I cut down into the rail with a router so the fit would be flush.
On top of the angles will be ¼ plywood, fiber fax, and then a aluminum firewall.
The second photo shows the access hole I cut into the lower shelf that allows me to
get a wrench on the top motor mount bolts. Notice the aluminum angle that is floxed
to the top shelf inside.
You can see I replaced the return spring system on the rudder cables to a nice wrap around
cable. The rudder actuation is much smoother now. I recommend the wrap around cable over
return springs.
Here you can see the 4130 brackets I used to tie the lower motor mount bolts into the
bottom of the fuselage.
An here are some shots of the entire mount. Notice I had to make the mount with a 5th pad.
This is so the mount clears the oil pan on the Lycoming.
Here are a few shots of the cowling making process.
Cowling off the mold with smooth primed Pig in the background
Whats that about carrying a big stick?
The making of the killer cowling mounting bracket. This is the ONLY way to build a mounting bracket on a composite airplane.
Here are a couple of pictures of the bracket being floxed to the firewall. Inside the edge of the bracket there will be a layer of fiberfax and then a sheet of stainless steel.
Here are some pictures of my friend Brads airbox that he uses on his Ellison TBI. It works great contrary to what Ellison says about this type of setup.
