What ever you say, Barry.
I suppose you are one of those guys who jumps up in your seat to help
the plane get off the ground after rotating?

Ah Paul... We all know that does not work.
What I do is eat a light breakfast for the flight out and for lunch I
drink seltzer because the bubbles go UP and the bubbles expand as the
altitude increases. Making the plane lighter.
Simple physics!

Hello, all
I am working on the (CH601-HD) firewall, and I am doing some changes based
on the XL and the 750 firewall.
The addition of the plastic upper bearing is causing me a bit of concern.
In my case, the bearing interferes with rivets placed through 6F10-2 (the
original CH601-HD upper bearing) and 6F8-2 (firewall stiffener).
These parts can be sen on page 11 of this document:
http://www.zenithair.com/pdf-doc/601-firewall-gear-rib.pdf
I am using UHDMW (or some such mix of letters) 3/8" thick.
I cut notches to clear the rivets.
What is bugging me is that I could not find any comments about this
interference, so maybe I am doing something incredibly wrong (I am not
content with doing anything just "credibly" wrong).
My "notched" upper bearing can be seen here:
http://www.flickr.com/photos/54366879@N06/7359287022/
These notches might be weakening the part to a point where it will easily
brake and be ineffective, reason why I am planning on a duplicate (no
notches) installed on top of it.
Comments, anyone?

Short answer: don't' worry
Long answer: Don't worry for a number of reasons:
- Try and break a sample of that material. Clamp half the length in a vise,
put an adjustable wrench on the other half and bend it at a 90 degree angle.
- it is a bearing, not a structural element. The side load is relatively
small and spread across the thickness of the material. And the load is
trying to compress or elongate the material, not split it.
- I did the same (but only for two rivets as I recall)
- I only see two bolt holes in your bearing, On the 601XL and 701 there are
four. See here:
http://www.zenithair.com/zodiac/xl/data/6-b-07.pdf
This being the Internet someone will immediately disagree with me.

Nice job on carving the piece out..... Altho it does like kinda fragile

Actually, gentlemen, the answer should be quite obvious. For best
takeoff and general performance, when you get in the plane, never put
your full weight down!

You are correct... That is why we have Light Sport Aviation.
When people were forced to go to the M.E. they never put their "full weight

Hi Carlos,
I had the same situation concerning fracture of the plastic which occurred
at my nose gear bearings. To reduce the possibility of
Compression fracture, I added an aluminum shim that spread the compression
of the fasteners that held the piece in place. It worked.
Also the holes for rivets could just as well have been a soft gasket
material between the bearing and the support to take up the thickness
of the rivet heads or bottoms. If these were pulled rivets, it might be
better to revert to using compression rivets to thin the impressions.

Hello, Larry
You make good points.
I like the idea of solid rivets - I could also set the (pop) rivet from
inside, but getting the riveter in that tight space might be a problem.
A solid rivet, installed with a squeezer, would work nicely...
And once again, I owe you one!
Actually, I owe you two: I just finished bending the upper longerons using
your setup.
I even managed to get the same wheels as the one you used.
It worked beautifully!
Best
Carlos
