John,
I hope you get to feeling better. With pain like that I understand why you don't
feel like doing anything. Work on healing up and then I think you will feel
like working on it again. Back pain is the worst.
Keep watching the list and stay in touch with all of us for inspiration.
Good luck,

Thanks Scott it's been about year and really in need of relief. I'm optimistic
and just wanted to let you and everyone know I'm still alive.
And when I can get off my ass and return to building I plan on doing that because
I ain't sellin my Piet as previously suggested by another list member.
Best to all

I'm getting a lot more done with the fuselage overhead.
$9 Harbor Freight bicycle lift good for 100lbs.
Current stage only weighs 50lbs.
Only takes about 30 seconds for one person to move it out of the way for the wife's
car.
I think I'd rather have a couple of nearby builders to help.

Wow, good question for a first post!
Right off the top of my head, I'd not want to lose a foot and a half of wing.
BUT, either case you mention involves making the wing panels a bit shorter. I'm
not sure any of this is gonna matter off the top of my head, but something to
consider with a wing bay deletion, or change in rib spacing, is whether you're
gonna have problems with drag wire interference with the ribs? All your struts
might wind up being a different length, and jury struts, etc (this isn't
a huge deal).
With a center section increase, are you gonna leave the vert struts in the same
place, or angle them outwards? If they angle out, they're quite a bit more complicated
to make.
You can scarf a section onto what you have to make them longer. Proper scarfing
on a spar will require plywood doublers, and then the inability to rout as much,
with a corresponding increase in some weight, but it can be done. Also,
not really supposed to have fittings through a scarf, so you'll have to plan on
where you scarf.
I'm not recommending you do or don't, or which way you go... just hope to have
brought up some things you may not have considered.

Grant,
Look in the SEARCH Archives, and you will see that a 4' center section with
12' spars was used by Steve Eldridge. I doubt if this affects strut length
or cabanes, necessarily. Look up Steve's email and contact him directly.

Grant,
Here's a link to the thread that Gary was referring to:
http://www.matronics.com/searching/getmsg_script.cgi?INDEX=45551305?KEYS=eldredge_&_section?LISTNAME=Pietenpol?HITNUMBER=17?SERIAL=15103830788?SHOWBUTTONS=YES
Steve writes that his center section was 4 ft wide, and his outer spars 12'-6"
(just like yours). as Tools mentioned, you may need to adjust rib locations slightly
to avoid drag/anti-drag wire interference, and you'll probably have to
do a little more thinking, but at least you will get to use the spars that you
already have. I don't recommend splaying your cabanes - that will complicate
your life unnecessarily.

Grant, and others
Don't over worry about the drag - anti drag wires interfering with "plans" rib
spacing (per say). I am considering slightly expanding wing span and using 3
sets of cross brace wires per wing - more X than stock plans. Just don't glue
or nail anything until you have dry fitted the ribs to the spars relative to
the X wires - and that goes for anyone regardless of wing span or how many brace
wires are used...

You mean like this?
The original plans as per the Flying & Glider manual
puts the span at 28 ft two in. So with a 36" center
section plus your 12"6" plus 1" each side for the tip
bows you'd be right there. If you want more span
then go 48" but you might want to splay your
cabanes some. Six inches past the cabanes is fine
but a foot might be a bit much. Go to this page and
scrolldown to the diagram and explanation just
below the lettering template. This will give you the
info necessary to figure out the forces on the wing
struts, inner and outer. What you'll see is that the
outer struts take the lions share of the load.
http://www.clifdawson.ca/Homepage4-10-06/Tools_and_Tips.html
As luck would have it, upon measuring the spar pieces, I discovered
that they were only
12'- 6" long vice the required 13'-2.5" long. Would it be problematic
to increase the width of the center section (I had planned on a 36"
center section - per Bill Rewey) an additional 18" to achieve the
correct total spar span of 29'-5"? OR Would it be a great loss to
keep the center section at 36" and the outer panel spars at 12'-6" (for

Curt- be careful what you wish for... you might get it. When you say you would
prefer to have a couple of nearby builder friends to help you with the fuselage
rather than to have a self-operated hoist system, I just want you to recognize
that the speed of forward building progress is inversely proportional to the
number of visitors you have in your hangar. If you could only get them to
come help you with an awkward task and then just shoo away, it would be great
;o) I must admit that I had two of the best, most helpful, courteous, and considerate
such hangar friends when I was in San Antonio. [UNCLASSIFIED] Steve
Dortch and John Kuhfahl were those friends. Always available and willing to lend
a hand, always polite about letting me get on with whatever I was working
on at the time.
Since things are a mite slow, I'll also take this opportunity to recognize one
of my brother's granddaughters, Emma Green. Emma is just turning 11 years old,
but she was only 8 when she got her first airplane ride. In my Piet, of course.
She loves airplanes, loves flying, and really played the part the day we
went flying. She wore a flight helmet and goggles, and we communicated via a
set of old WWII carbon mics and headphones, shouting back and forth into the
old black mics, "HOW ARE YOU DOING; OVER"... "I LOVE IT; OVER"... "DO YOU WANT
TO GO AROUND AGAIN; OVER"... "YES, PLEASE; OVER"... and like that. What fun.
