Pietenpol-List: Control horn construction
Original Posted By: "Greg Cardinal"
Can someone tell me what the most common type of construction is usedfor Piet rudder, elevator and aileron horns. I can't say I like the horn construction in the plans. Edge welding .031" steel without burning it up seems almost impossible ( I haven't tried it yet ) and also The attachment flanges seem awful thin. I've seen some cut out of flat stock but it seems they wouldn't haveenough side to side strength, maybe I'm wrong there but if someone couldlet me know what is the most popular way of making them I'd appreciate it.

Ed, I welded mine up using gas and a #00 tip. Practiced a bit onsome scrap, and had no problem doing the weld. I welded up somescrap and gave it the bend test, 360 degree, with no failurte.Finally cracked about 3/4 inch from the weld. Weld =did not fail,and looked good when cut and polished. Great video available fromthe EAA, that walks you througfh what to watch for, and how tocontrol the puddle. Lots of practice and testing, then a piece ofcake!----- Original Message -----

I worried a long time before trying to build one and found out they gotogether very easy. Turned out the hardest part was cutting them out. Youmay want to wait until you are ready to rig elevator cables before buildingthe elevator horns or at least plan them with an angle in to match how thecables will go. I also welded in a U shaped insert to beef up the flangesand seal off the interior of the horns. The .032 gives a very strong horn. Wayne Sippola, Winnipeg ----------

Go to this web site they sell all kinds of parts for Piets, they also have a catalog which I just got the other day very nice.http://www.replicraftaviation.com/piet%201.htmGaryNew Orleans________________________________________________________________________________

Subject: Re: Pietenpol-List: Control horn constructionEd, I made the elevator and rudder horns per theplans already and plan tomake the aileron horns when the time comes -- later this summer. Theyare not easy to make. The hardest part is bending the steel to fit. Iuse a ball peen hammer and just bent against my shop vise at the backside. I had made a couple of forms to hammer against, but neither workedat all. Using the vise wasn't really too difficult and I was able topound them out in a couple work sessions. Welding wasn't difficult atall, but I'm used to welding thin steel. The two elevator horns don'thave the same spread out width, but I don't think we'll have anyproblems. Others who have seen them seem to feel they'll be OK. One change we are going to make, and haven't yet, is we are going tobraze small bushings into the bolt holes to minimize wear on the bolt andto prevent hole elongation. This will just give more surface area forthe cable attach bolt to ride on rather than the knife edge of the thinsteel. If I remember correctly, we used thinner steel too, like .025 orsomething like that. It's been awhile. so I don't really remember whatthickness we used. At the time I did send a message to the BPN with thesizes we used throughout the project and it was printed.John LangstonPipe Creek, TXnle97(at)juno.comBuilding the wing now ________________________________________________________________________________
