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 ________________________________ Message 2 _____________________________________ Time: 05:18:17 AM PST US From: HelsperSew@aol.com Subject: Re: Pietenpol-List: Re: Aluminum struts-what size?

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.

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.

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.

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?

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.
