Elevator Push Rod Tunnel

Hey Gang!
How did you attach the formed tunnel
to the aluminum decking?

Rivets, screws?  I don't find it covered
in the manual, of course...

Also, it appears that the bushing tubes
don't line up very well, so this push rod
will be in a constant bind. Do I bend it
a little to make the connection points
line up, or just let it flex?

Thanks!

John

Using set screws there. If rivets have to be drilled out for some reason, it could introduce a lot of metal particles into the inside of the fuse fabric.

A slight bend in the push rod made this one fine, as others have done.

I used wood flooring - so screws worked just fine.  I found that a few small adjustments (bends) were needed to make the rod work  smoothly.

Mine came with the self tapping screws.  I used them right to the aluminum decking.  Worked fine.  Then covered with carpet material right over that.  Did not fill in the sides like some do.

Hey!

I had no idea those screws were there!
They sure supplied a lot of them!


I do intend to put do 3" of blue styrofoam to
level it out. I think it will cut down on noise
too.

Thanks gang!

John, that's what the guys at Cornell do, they use foam to level the flooring.  I plan to do the same. see picture

Hi, Just gang,
I'm a new member, about 1 year into construction of an escapade with a Rotax 912 ULS.  
I added the foam filler around the elevator tunnel, but also added a 1/8 layer of lexan on top of the foam so my knee wouldn't dent the foam when I crawl back to the cargo compartment.

I decided on an open cell foam layer of about 2 1/2" on top of the filler foam for a more comfortable berth and to protect the lower foam from denting. If it's not enough, the Lexan sounds like a good additional layer.

John S,

Welcome.  You're not far from where I am, just north of Hamburg, PA.  I go down to New Garden frequently for work so some time we'll have to get together for lunch.
