| Subject: | My measuring mistake |
I've discovered my tail post is 1" too tallit's 11 7/8". This "too tall" mistake
carries forward to the pilot seat back where the fuselage is 3/8" too tall (the
start of the error).
I'm about to dig the nails from gussets before I start the job of gusset removal.
I was wondering how much of an affect that extra inch would have on weight & balance
as well as handling characteristics; the rudder would have to be increased
an inch.
Just something to ponder on a dreary day here.

John,
I am building a Piet with a steel tube fuselage, so my questions only come from
looking at the plans, not actual experience building the wood fuselage. So take
it FWIW.
Are your top longerons parallel with the ground, or is there a slight bow in them?
If they are have a bow, then my guess is that you have a problem.
However, if they are parallel to the ground, then are you saying that the tail
post is an inch too long? In other words, it extends 11 and 7/8' below the top
longeron? If so, can you not just make the vertical stabilizer 44 and 1/2", not
43 and 1/2", as the plans show?
Builders of the wood fuselage may throw a rock at me for suggesting it, but that
is just my initial thought.

| Subject: | Spring Landing Gear designs |
Hi all,
A long time since I posted anything. Yesterday morning on pre-flight I
noticed that the lashings on one of my bungees was slipping. Its time
to change the bungees anyway, and it seems like a good time to convert
to spring struts. I have Hans VanderVorts design in hand, and I've also
looked at William Wynn external tube design. Those of you already using
these designs, are you happy with the spring that ACS sells, or did you
use something from McMaster Carr that works as well? I've seen several
Piets with the exposed spring design, but haven't seen one like the Wynn
design, though it looks like it would be easier to convert using pieces
from my existing gear. Your thoughts welcome!

| Subject: | Re: My measuring mistake |
Thanks Terry. The problem is at the lower longeron. When laying out the jig, I
apparently measured 10 7/8" from the outside of the top longeron and made my mark
for the bottom longeron, but placed the inside (not outside) of the bottom
longeron there, giving me a tail post 1" too long.
The top is straight. If I leave it as it is, I'll have to extend the rudder an
inch. I'm not sure what else could be affected. I'm trying to stick to the plans,
so this irritates me.
I'm curious, though, how much that 1" would affect the aircraft. It's a gentle
curve from the tail to pilot seat back where the plane would be only 3/8" too
tall

Really, I doubt it would matter at all. Folks use all manners of tailwheels, some
which change their own weight by that much as they wear.
Aerodynamically, cannot it would matter either. This airplane lives in the middle
of a wide range of good. About the only hinky thing is weight and balance,
which should be checked anyway, and which is correctable for that minor amount
of weight a thousand ways.
The real issue is how YOU feel about it. Fixable with a lot of work, about two
bucks of epoxy, and five bucks worth of wood.
This plane was designed for 150 lb pilots, but 200 lb'ers are flying it. Nice
spruce but dense doug fir is used. 1/16 wires but 3/32 is used... This isn't
that big of a deal. I'm a fan of build to fix anyway, rather than strict plan
compliance. FEW eyes are calibrated to one inch on this plane. Might matter
on a Queen Anne period reproduction... But not this!
In fact I'll bet things like cockpit wing cutouts, and scalloped trailing edges
change the square inch amount of rudders and stabs more than this.

John;
What's funny is that I have seen discussions about how if the airplane is built to the plans, the lower edge of the rudder protrudes below the tailpost just a little. So, it may be that you're ahead of the game ;o) Here's an example, Chuck Gantzer's Piet: http://www.westcoastpiet.com/images/Chuck%20Gantzer/images/ride.jpg
Here's another, Gary Boothe's:
http://www.westcoastpiet.com/images/Gary%20Boothe/images/P1040823.JPG
And another, Kevin Purtee's:
http://www.westcoastpiet.com/images/Gary%20Boothe/images/P1040823.JPG
And finally, you can see in this very close-up photo of Kurt Shipman's airplane
that if you don't flatten or round-off that very last bit of the rudder, it will
be just a bit longer than the bottom of the tailpost and won't fair into the
line of the lower longeron.
