Since you are in Canada, you might check with the PegaStol people. My
PegaStol wings came with extruded struts, I don't know what grade they are,
but they ain't going anywhere.

Keith,
I used a hand squeezer on all the trailing edges of wings, slats, flaperons,
elevator. Its advantage is consistancy. Once the squeezer is set up for
proper amount of squeeze every rivet will be exactly the same which is great for
looks. Its also much quicker than pulling rivets. I clecoed every other hole
and dropped a solid rivet in every other hole, squeezing took less than 3
minutes.
This works great with the normal yoke provided with a hand squeezer, the
spar might take a much bigger yoke which is much bigger bucks. A pneumatic
riveter will come in handy when you do the flaperon and elevator bellcranks.
Brian
What are the advantages/disadvantages of either pounding rivets
or using a squeezer, as I am getting ready to build my spars (CH701).

Loctite 592 is what you need, it is a Teflon based sealant made for the job.

Given the fact that many in this group are at Sun & Fun this wekk I'll post
this next week as well.
If you're interested in participating in a group insurance scheme, send me a
note and I'll put your name on a list.
Once I get a sizable list together I'll approach a few of the big
underwriters to see if they're interested in writing a group policy.

| Subject: | Horiz Stab Question |
--> Zenith-List message posted by: "Joe Kerr" <kerrjf@charter.net>
A couple of builders have noted on their web sites that the ends of the horizontal
stab are bowed inward slightly because the four center-most ribs are installed
on top of the spar doublers, but the doubler does not extend all the way
to the end of the spar. This leaves the third rib from the center on each side
drawing the spar inward because it is not installed on top of spar doublers,
so the fore-aft span is shorter. The rivet line of the skin needs to take this
into consideration or else the rivets may end up too close to the spar flange
bend, if I understand the problem correctly. I am just wondering how many
of you altered your rivet line to account for the slight bowing of the spar, OR
have any of you inserted a shim between the ribs or spar, OR is it really no
big deal either way and you ignored the bow and all the rivet placements worked
even with a straight rivet line?

Jim,
I have just hung my engine on my 601XL. It is nose down by 2 degrees when
measured between the top of the engine and the lingering. Is that normal?
+++ Very normal. If you want to get rid of some AFTER test flights you can make
C-shaped washers out of .063 or .090 aluminum and slip 'em in between the bottom
mount pads and the firewall. You won't have to disassemble anything, just
loosen the bottom nuts. Make them a bit bigger than the engine mount pads and
safety 'em.
+++ This is another "cure" for you guys who think you have to realign the stab
because you need a bit too much up trim (in cruise) as it takes out a bit of the
downthrust.

I am not sure if this is the same problem, but I had a
similar problem with the rear spar bowing in when I
strapped the skin down with the blocks on the rear
spar to keep the straps from bending down the skin.
The force on these blocks buckled the ribs out of
line, and bowed the rear spar. So what I did was cut
blocks of wood that just fit inside the ribs on each
side, and gave the correct spacing from the front to
rear spars. I bolted these through holes already
drilled in the ribs to clamp the rib webs straight.
Then I strapped the skin down and the webs of the ribs
didn't buckle, maintaining the spar spacing with the
straps in place. And everything on my stabilizer
drilled and clamped up straight.

| Subject: | Engines for 601 XL |
--> Zenith-List message posted by: Don Mountain <mountain4don@yahoo.com>
I am working on the wings of my 601 XL, and starting
to think about engines. Flying a Piper Cherokee with
a Lycoming that looks like an antique out of the dark
ages, I have been thinking of something a little more
modern. I know a lot of people have tried various car
engines, like Volkswagon, Corvair, Sabaru, and a few
others. And of course the non-certified airplane
engines from Jabaru and Rotax. All of these seem
either expensive, old or exotic here in the midwestern
United States. The designs for the Volkswagon and
Corvair engines are more than 30 years old now, so I
consider that rather antique.
So the question is, has anybody tried something a
little more common and modern in design for their
airplane. Something designed and built within the
last 5 years, but common enough to be easy to get and
still get parts at the local dealer?
I was looking at the engine in my wife's 2003
Chevrolet Cavalier the other day, and wondered if
anybody had tried one of those. Its a double overhead
cam engine, thats all aluminum, and fuel injected that
takes regular fuel and seems to run real good and
smooth. And it looks pretty lightweight. Probably
some of the other manufactures have similar engines
that are plentiful in the junk yards or from a dealer
brand new. I wonder what kind of design problem there
would be installing one of these in a plane? It would
be nice to use the same oil filter in the car and
plane. Or if I needed spare parts, I could borrow
them from my wife's car?

I just made the first (of many) mistakes on the stabilzer and I was wondering
if anyone else has had a similar problem;
I measured the 233mm measurement for the front spar attachment, cut the plywood
blank and mounted both pieces of 6t2-2.
Once I drilled the holes for both 6t2-2 I realized that those rivet holes were
too close to the inside bend radius of 6t2-2 which put the corresponding rivets
in 6t2-1 right next to the edge, which of course was much less than the specified
10mm for edge distance. I will order new 6t2-2 fron ZAC but I don't know
where I measured incorrectly. I rechecked the plywood blank and it is indeed
233mm. I remeasured the placement of both 6t2-1 and 6t2-2 without the plywood
(I measured both equidistant fron centerline and also from the end of the spar
itself) and I think I have it about right now, the edge distance on 6t2-1 is
now ~8-9mm and almost the same for 6t2-2.
how accurate does this measurement have to be? I am +/- 1-1.5 mm as it is now,
before adding the new pieces which I will order this week. Any thoughts? has
anyone else had similar problems with spacing of the front attach points or am
I just going nuts????

Brad-
I mounted 6T2-1 and 6T2-2 two weeks ago and didn't run into the same problem.
I have 8mm edge distance on 6T2-2 and 10mm on 6T2-1. The 233mm wooden spacer
is a recent plans revision (2/05), the plans from 12/04 call for a wooden spacer
of 219mm. If you have a pre-drilled spar, perhaps you have the earlier version
that is drilled for the 12/04 spacing.
