--> Pietenpol-List message posted by: Matt Dralle <dralle@matronics.com>
Dear Listers,
Well, its November 30th and that means three things...
1) Today I am officially 42 years old (sympathy is appreciated)!
2) It marks that last "official" day of the List Fund Raiser!
3) Its the last day I will be bugging everyone for a whole year! :-)
If you use the Lists and enjoy the content and the no-advertising,
no-spam, and no-censorship way in which they're run, please make a
Contribution today to support their continued operation and
upkeep. Your $20 or $30 goes a long way to further the List
operation and keep the bills paid.
A Lister wrote a funny message in the comments field of his
Contribution that I thought summed things up pretty well:
"Worth every penny and I'm a tightwad!"
Thank you to everyone that has made a Contribution so far this
year! It is greatly appreciated.

I noticed on the plane in the foreground that the bolts holding the
struts at the wing are upside down.Up here in cold Canada we usually put
those or any bolts in with the head up and the nut down.If the nut
should happen to come off then the bolt will not come out right
away.With the bolts done in the fashion in the picture you are inviting
trouble.We also have the heads on the front side as well ;in other words
all bolts face with the head at the front and the bolt facing the back
or rear or the aircraft unless of coarse there is a situation where this
is not allowed.

| Subject: | gussett grain direction |
This probably has been asked before but, does grain direction matter on tail gussets.
I have the new CAD GN-1 plans and the only place where I can find that
the grain matters is on the nose rib, unless the hatching on the gussets is supposed
to represent grain. Initially I thought it was just a standard 45deg
hatch pattern to show where the gussets were. Looking closere some of the patterns
are less or more than 45deg. I cut out all of my gussets for the tail without
regard for grain direction to save material. I have also assembled the
rudder and vs with these pieces. What should I do. I am using the GL2 birch
plywood from ACS.

| Subject: | gussett grain direction |
Compression strength of birch is about 8 - 10 times higher parallel to
the grain than it is perpendicular to the grain. Having said that, I
would say that it almost certainly doesn't matter, since it would be
difficult to predict the direction of the loading stress on the tail
structure. Birch is considerably stronger than mahogany, which is what
many people (myself included) use on the tail, to save weight.
When I had a forced landing about this time last year, one of the areas
that received a lot of damage was the horizontal stabilizer, which I
ended up totally replacing with a new one. The stabilizer impacted the
side of a ditch, and the right leading edge and spar broke in two
places, each. The right trailing edge broke in one place. None of the
mahogany plywood gussets broke. In general, I lined up the grain of my
gussets with the long axis of the gusset.

| Subject: | Straight Axle Landing Gear Fittings |
I'm cutting the fittings for the straight axle landing gear and was hoping someone
could help with the dimensions of the inside fitting.
The Flying And Glider Manual drawings on page 17 give a dimension of 3/32" from
the lower bolt holes to the fold line. Obviously this is incorrect, what measurement
have you guys used?
Whist we're on the subject, how are the slots for this fitting accurately cut into
the fuse floor?
Thanks in advance.

Harvey
Thanks for noticing those details. I will turn those upper attach bolts
around to face heads forward. On the strut attach bolts, I did that
intentionally. Notice that the bolts are extra long, they are grade 8.
They are to hold the tie down ropes. I had this discussion with the DAR and
an FAA inspecting supervisor and both approved.
I appreciate much anytime when something that appears wrong is pointed out.
