Bob,
I had mine built by Ron Kelly down in TX. He builds very strong
modified A's and has done a few for piets and has no problem with it.
Mine has been running very strong and reliably on it's stand for a
couple of years now and I was pleased with his work. He's expensive,
but worth it. He has dyno results on his site.
His # is 972 771 1911
Good luck
Douwe

| Subject: | Re: Prop drawing |
Hi Santiago,
I do have a blade drawing of the 2nd prop that she flew with. This prop is an 80
x 43 and was designed based on the performance calculation of my Pietenpol,
NX3116, it was the 2nd prop I carved.
This may/will not be an effective prop for your plane unless your engine is putting
out 57 Hp @ 1600 rpm at cruise, which my calculations were based on. You
need to be in the peak torque range of the Model-A for the best airplane, engine
and prop combination. Using a typical prop off a C-65 will be more efficient
at 2200 rpm and well out, and on the down side, of the torque curve for the
model-A. High drag planes, like the Pietenpol, fly best with big slow turning
props moving a lot of air.
If you do not increase the horsepower of the Model-A, 37 HP, you will still want
to design a prop to be in the 1600-1700 rpm range and well within the peak torque
range of the engine.
It flies better with this combination.
Let me know if you still would like the drawing and some pictures of my prop.

Thought of screws, however everything I read said don't use screws on aircraft
woodwork, rather to look at the brads/nails as temporary clamps for holding while
the glue drys.
Didn't see glue for the leading edge that came loose, so I mentioned it.
Does give me a chance to really clean out the area that will be enclosed and get
the dust out first, so its probably a good thing.
Think I will put some kind of extra cloth tape over the brads to make the covering
cloth look better and make it less likely they will rise and look ugly.

I used annealed .050 3003 for the nosebowl and .032 6061T6 for the
flatwork. I got a cowling plan from the Cub Club and adapted it to the
specific shape of
the Piet and of my engine mount.

| Subject: | Basic plans reading question |
Ok, as an example of how little I know when it comes to building....
Looking at the plans raises this question: how do you read the dimensions?
(I am literate, so please reserve the Hooked on Phonics responses, har har. :P)
For example, with the ribs. 1/2" x 1/4". I'm assuming that is width by height.
If that is the case, does that carry throughout the plans? For the horizontal
stab diagonal braces, they are drawn as 3/4" x 1/2". If the plan dimensions are
listed as width by height, that would be 3/4" wide by 1/2" high. Is this the
case.
I feel stupid for asking this, as it should be a simple thing, but this is probably
the first time I can recall building from scratch via plans. I checked that
archives, but didn't see any question/answer addressing this, I'm sure because
I can't really figure out what to search for on this topic.
Thanks,
Ryan

I was thinking I could get by without a planer (as much as I've wanted to buy one)
and thought of a reason I might be able to justify the purchase. I was recently
given 4 rough-cut Sitka Spruce boards 2" x 6" x approx. 14'. I was hoping
to use them for longerons but they have a bit of a warp in them. Would the
wood still be usable if I were to cut it in to smaller pieces (suitable for
tail feathers, compression struts, etc.) and clamp the smaller pieces into a perfectly
straight jig that would hold them in a fixed position as I plane off
any warpage by passing the whole piece in the jig through a planer? The pieces
are not badly warped, just not perfect, and if I used them for small pieces,
what I call warpage might even be acceptable for some folks without planing.
I could just buy more spruce but I'm sure I'd find uses for the planer in the
future. Has anybody heard of using a planer for this?
Thanks

Cut the boards on the table saw first a little over size.Then run them
through the planer.
A lot less waist and you get square corners.

I have a Delta 12 1/2-inch planer. Its simple and inexpensive. I like it a
lot and it come in very handy when I need a board reduced to a specific
thickness. If you own one, a hole new world opens up to you. You can buy
ruff-cut board (cheaper) and make then into beautiful wood. You would be
surprised what an ugly looking 2x4 will turn into after you run it through a
planer. As for taking the twist out, it will not do that. It will only
make the two side parallel. If it goes in twisted it comes out twisted. But
I think you already know this. If it were me, I would cut them into
longerons and see if the twist is that bad once you get them machined down
to 1x1. Cut one side on the table saw then cut the other on the table saw
or jointer to 90 degrees to the first, then run through the planer. I would
bet that starting with a 2x2 you would have usable 1x1s by the time your
done. You can always use them for smaller pieces if it doesn't work out.
