Thank you Ray. In fact, yes, I did. But there are other factors: I am a
mechanical engineer and a (good) practical mechanic. The welds were made by
one of my student technicians (the best actually). I used to build violins
hence the woodwork. I have to admit that I had to rework some parts,
because I let my woodworking apprentice homebuilders do some of the job.
But that's life. You learn from mistakes, don't you?=8B They got much
better
now, so I (sometimes we) cqan work faster. Since I am a full time employee
at the age 67, I only have weekends but metal work is done where I work, it
is a bonus.

| Subject: | Fuel Tank, Size/Location |
Thanks guys for all the previous info on a nose tank.
Now the question is will I have enough pressure for gravity feed to the
Carb? I am planning to have a single seat Pietenpol. I would like to locate the
nose tank where the passenger seat opening would be. I am thinking an oval shaped
tank 16" deep at the center and about 18" long. It will be located with approximately
8" of the tank above the longerons and 8" below. With the fuel valve
at the rear of the tank will there be enough pressure for fuel to flow to
the carburator on a Corvair engine with 2 gallons of unusable fuel in the tank?
Looking for opinions, experience or suggestions?

Again, not to beat a dead horse but the Tony Bingelis books not only talk about
rigging but flight testing and in-flight
procedures to see exactly what needs to be re-rigged and how to do it. Very systematic,
very logical approach and using his
procedures keeps you from chasing down the wrong flight control axis that you may
'think' is the problem but it might not be.
Uncle Tony knows best and tells you exactly how to do it.

Hello Harvey,
Everyone builds their Piets a little different from each other. That said, I have
never seen one with the fuel tank in the location you are speaking of. There
are some problems I would think you need to work out. Mostly math and some
testing. The amount of head pressure you will have will be a direct result
of how hi the fuel level is when measured from the inlet of the carburetor. As
the fuel burns off, there will be less pressure resulting in less fuel flow.
You could build a mock up and test it.
The bigger problem I see if you were to have enough flow, is with the location
of the fuel pick up. If you were to have only one at the rear of the tank, It
could become un-ported when you are descending for landing. Piets are very draggy
and the approach for landings tend to be rather steep.
I don't personally believe putting the tank in that location is a wise one. I
do think there will be fuel delivery issues. It takes up space that you could
at least put some camping gear in if you wanted. Then there is the problem of
having fuel in your lap in any kind of accident.
Please consider these issues. If you do decide to put the tank in that location
you will be testing something that hasn't been done before. At least that I
am aware of.
Good luck with what ever you choose,
Respectfully,
--------
