I'm at the point that I will be putting the drag/ anti-drag cables in thefirst wing, and have a question on the bkts that hold cable at wing tip.Looking closely at the prints, I'm not sure if they show two fastenerscomming out at the end of the wingtip where each spar attaches. I firsttook it as one bkt on each spar on the inboard side to hold the cable. Isthis right? Did you bring bolt thru tip? One bolt or two per spar?My plan was to use one bkt on each with a wood screw into tip. Now I'mrethinking due to this acting as compression strut also.What did you guys do?thankswalt evans________________________________________________________________________________

Joe, if you're looking over the nose of a taildragger on landing, your Pietwon't last long enough for you to decide whether you like the arrangementor not!! (smile)I accidentally erased an earlier response from someone who mentioned thatyou could bend the rudder horn with the hanging pedals. I was talkingabout the front pedals, you have the rudder bar in the rear cockpit eitherway, so no dice on that idea. I know that I have been told that there wasa problem with the hanging pedals, but can't recall what it was. Also, tothat same person, you do eliminate the center pulleys, brackets, and atleast four bolts through the spar. Of course, you add the "spools" on thelower longeron, but I think it is a net weight loss. Still wondering ifthere is some other reason for the "improvement." I agree, if Berniethought it needed improving, it bears a look.----------

Joe, if you're looking through the wires in front of you on landing in ataildragger, your Piet won't last long enough for you to decide whether youlike the aileron arrangement!! (laugh)I accidentally erased a response from another person who said that youcould bend the rudder horn with the hanging pedals, but I meant the frontpedals, you still got the rudder bar in the rear cockpit either way. LikeI said, I have been told there was a problem with the hanging pedal design,but don't remember what it is.On the ailerons, I would eliminate the center pulleys, brackets, and four(or two?) bolts through the spar by using the old version. Of course, itdoes add the "spools" on the lower longeron Joe refers to, but a net weightloss nonetheless. Jack McCarthy near here has a model A Piet flying withthe old aileron arrangement, his only gripe I know of is that the cablemakes it harder to get into the airplane.----------

Subject: Re: Pietenpol-List: attaching spars to wingtip questionWalt... I could not see using the wing tip bow as a compression member...which is what it becomes if you follow the plans. The tip is glued to the spar as a butt joint which we know is not strong, plus a couple of angle brackets. I added a compression member just inboard of those brackets so that the tension on the drag and anti drag wires will be taken up by this member. The added weight I believe is well justifiedDon Hicks________________________________________________________________________________

Jason, Piet NX899TC has the wings off for winter, but you're welcome to cometo Des Moines and look at mine. Give me some warning and I'll give you thetour. If you wait until spring I'll take you up in it. My rules for ridesis you have to weigh less than 300 lbs, be able to get in without destroyingthe plane and not have a backside so big that I can't work the rudder bar.Copinfo(at)home.comTim CunninghamDes Moines, Iowa (515) 237-1510----- Original Message -----
