(Catdesigns) ________________________________ Message 1 _____________________________________ Time: 07:33:15 AM PST US From: "Oscar Zuniga" Subject: Pietenpol-List: pedal return spring I've scanned and uploaded a photo of Dan Horton's pedal return spring setup, at http://www.flysquirrel.net/piets/pedalspring.jpg You can see the spiral-type spring that holds the pedals in place and maintains tension on the rudder cables. I thought it was clean and clever. Also visible in the photo is Dan's heel brake setup. It isn't real clear in the photo but what he has are small heel brake arms that he fabricated from aluminum stock, with the braking force transferred from the brake arm to the actuator arm via a rod or tube that is concentric (inside) the rudder pedal pivot tube. That puts the brake cables all the way outboard, out of the way against the inside of the cockpit wall, with a straight shot down to the mechanical drum brakes. Not only did Dan's airplane win awards in its "Canuck/Jenny" configuration after he completed it, but it was again a show winner last year (I believe), also appearing in a feature story in Sport Aviation after Dan sold it and it was repainted and marked as a different airplane. Was it a Navy paint scheme? I'm over the hill now and don't remember too well ;o) Oscar Zuniga San Antonio, TX mailto: taildrags@hotmail.com website at http://www.flysquirrel.net _________________________________________________________________ Like the way Microsoft Office Outlook works?

Is it necessary to secure the bracket to the longeron with bolts and nuts or will two wood screws (maybe with a little epoxy on the threads) be enough?

Hi Gus, The 1/8" cables between the lift struts are adjustable with turnbuckles. On NX18235 the outboard ends are attached to the lift strut attach bolts using a cable pull. The inboard ends are attached to an eyebolt that also serves as one of the gear leg mounting bolts.

My email went down after i asked that question and i've been gone since Tuesday with my work. My little world was just shattered today when my daughter called and told me she had heard that the road was closed a few miles south of the airport at Carrollton MO where we keep our Champ. I thought no big deal because we are quite a ways from it. I got with the Opts manager at our office where i work out of and told them i needed to get home to check on my plane (I truck for a living) and they got me in this evening. I work in Kansas so it was about 9:30 this evening when i got to Carrollton. I could not believe it-I could'nt even get to the airport because of the high water. I'm guessing that there is 2 to 3 feet of water in the hanger. Words can not even begin to express the feelings i have now-disbelief to anger (at myself). This happened in 93 but was only supposed to happen every 500 years. I'm a half hour north of the airport but will go back tomorrow and try to find someone with a boat to take me out to the airport. Hopefully i can get it up on a makeshift stand to get the water out of it if it is that deep. I'm so emotionally down now that i have to taslk to someone and i know this group is the one to go to even if its only for moral support.

If that's what you mean, then it can be a suitable substitute for Sitka Spruce (almost identical density, with higher strength). Ask the lumberyard exactly what species they have on hand. Check the weblinks that Chris Tracy posted yesterday, and you'll see Western Hemlock listed in the charts. Go to the Matronics Archives, http://www.matronics.com/search/ and do a search in the Pietenpol Archive, using the word "hemlock". You should find enough reading to keep you busy for a couple of hours. As you read through, you'll see that at least one builder (Clif Dawson) has built almost his entire airframe using CAREFULLY SELECTED Western Hemlock. I can't recall the source, but I definitely remember reading that BHP built laminated spars from carefully selected lumberyard Hemlock.

Gus Yes, the wires are VERY important. The vertical loads on the wing are supported by the two struts. The struts on a Pietenpol are parallel to each other. This configuration does not resist for and aft loads very well. The wires take the for and aft loads keeping the struts and wing from rotating front and back. They are only loaded in tension so wire works quite well and are lighter then tubing. See attached drawing for a pictorial description. The same explanation works for the cabain struts as well as the wing struts. Some designs, like a cub, angle the rear strut forward to do away with the wires and take the for and aft loads. This requires a very strong fitting where all the wing loads are concentrated. Mr. Pietenpol chose to divide the load into two thus making it safer for the light weight structure to carry the loads.
