Subject: | Re: Rib to Spar fit |
Thanks for the input guys. While waiting for replies, I did a little more checking.
I found my cap strip locator block at the bottom of the spar was located
too high. Also, the cap strips are over 1/4" thick. Even accounting for those
issues I will have to lower the locator block slightly more to get 4-3/4" at the
rear of my 1" spar.
It also makes sense to bring the bottom of the rear spar down slightly so the 2
spars are on the same plane since I am building a 3 piece wing.

I have been asked to describe how the Piet flies. IE what is it like. I
have only been up on a Piet once, years ago (Curse you Oscar Z for
infecting me with the Piet virus). It struck me as being very Cub like
except the open cockpit was a totally overwhealming sensation.
What is a good comparison?

Hi have a Piet with an A-65 and a J-3 with the same engine. My
Pietenpol has a 40 inch pitch prop, which would be the climb prop for
the Cub. My Cub as the standard 42 inch pitch prop. The Piet gets off
the ground a lot faster than the Cub, and still flies about 2 mph faster
(not much difference). Stall characteristics are similar, as are
landing speeds. Flying the cub with the door open is very similar to
the Piet, except you can't see as much on the left side. Gross weights
are very similar, I grossed my Piet at 1200 pounds and it hauls that
weight well.

I'm not the best source. I had a Grega with clipped Cub wings. So, an open
cockpit Cub that dropped like a rock when power pulled back. I noticed that
in Baby Ace. I had some J-4 time prior to the Baby Ace. Floated like a
kite, I thought.
I wnat to fly A Real Piet, preferably a Model A powered one!

Subject: | Re: AN42B eye bolt for hinges |
I agree that the weight difference should be negligible. As far as the space, I'm
going to use a Forstner bit and go in 1/8" on both sides, reducing the gap
by 1/4". Additionally, I can then purchase eye bolts with a grip of 1" instead
of 1 1/8" which comes out to almost $3 per bolt (times 27...for $81 savings).
As a reminder, the bolts have to pass through the 1" beam plus a 1/8" ply that's
added in bolt locations.
Here's a photo of some cast aluminum pieces. With bolts, I think there's slightly
less material but the aluminum is probably lighter than the eye bolts, so maybe
a wash.

Steven, I think the Cub comparison is pretty close, except when it comes to
glide. The Cub is a floater, the Piet is a bit of a brick. I've rarely bee
n able to get a good full 3-point landing in the Piet because the sink rate
really goes up as the nose goes up. Wheelies and tail-low wheel landings w
ork fine.=C2-

Matt, I found to consistently get good 3 point landings I can add a
little power (maybe 1200 RPM on a Continental A65) which adds just
enough float to let it settle in nicely on all 3 wheels.

Hello all pietenpol builders, it seems an easy way to solve the discussion about
the hinges would be to machine hinges out of solid bar stock. If someone would
either send or post an accurate drawing or even send a sample of one of the
cast hinges I would be happy to program our CNC mill to crank out a bunch. If
you send one I will gladly return it ASAP.

Hello all pietenpol builders, it seems an easy way to solve the discussion about
the hinges would be to machine hinges out of solid bar stock. If someone would
either send or post an accurate drawing or even send a sample of one of the
cast hinges I would be happy to program our CNC mill to crank out a bunch. If
you send one I will gladly return it ASAP.
