I want to run a couple of questions by the group:1. Those of you running Model A engines, how do you have it timed? 30 before TDC sounds about right, but not sure.2. All of the photos on here lately that show the cockpit coaming have it ending a few inches aft of the panel (on the sides). This is how I want to do it, although the drawings show it continuing all the way around, which I do not care for. What are most of you doing? What dimension?? TLAR (that looks about right) or is there some dimension used most often (I was playing with 6-8" aft of the panel, but that may be too far).Thanks for any help,Geneworking like crazy to make Brodhead '09________________________________________________________________________________Date: Tue, 24 Feb 2009 09:52:38 -0500

Pietenpol-List: Re: couple of questions

I finished my controls and was setting up the loop from the stick to the reverser and back and I ran into a problem that I and my tech counselor are both worried about. The system is built according to plans other than a thin hardwood strip above the cable exit point and a turnbuckle to adjust tension. When rigged with a tension that feels good the cable is fairly slack and when you go full stick forward the cable rises off the front pulley. There is a also a noticeable but not severe "hump" as the stick transitions backward movement and the cable tension changes. If I tension it where the cable does not rise off the pulley moving the stick takes a fair amount of force, the "hump" is very pronounced and I can't imagine any feedback being felt. Neither of us has ever seen the piet mechanism in person before I built this one, and he is a talented RV guy but has limited cable system exposure. I am stuck between the notion that cables rising off pulleys and such is unacceptable and that the problems are part of the design and the reality that Piets have flown for 80 something years with that design. That would normally tell me I have done something wrong but neither I nor my tech counselor can find a meaningful deviation or a mistake. Any ideas? -Scott________________________________________________________________________________Subject: Pietenpol-List: Re: couple of questions

How's this? Subject: Re: Pietenpol-List: Re Tail dimensions Cliff, I went back and looked at your tail photo. Can't make out anything. We need a close-up to see what you are talking about.

Yep. A couple of years ago, at Arlington, I cameacross a new two place sport plane, the name ofwhich escapes me. There were no turnbuckles onthe tail. I couldn't believe that was possible todo that but there it was. It was explained to me thatadjustment was simply a matter of twisting anduntwisting the wire. So I've done it to see and so farit's worked. There's a bit of a trick to getting thetight wires to line up with the holes in the fittingsbut if it works out OK when I actually get the thingflying then I've saved some weight where it's mostimportant. Like everything we do the proof will bein the pudding. Right?----- Original Message -----

Subject: Pietenpol-List: waiting on parts or refundNormally people selling parts have them in stock,or can give you a time that they will be able to deliver the part that you have paid for in advance as a lot of us have paid WW in advance by PayPal or check. After that you can't find out anything by email to them. Still waiting after almost 10 months,I have asked for a possible ship date or a refund if you aren't going to producethe goods. I have been totally ignored with no reply so I have to assume this is WW's way of doing business. I have even ask by email if certain items are in stock that I would love to have ,No answer. I do not want order some thingelse to have my money tied up for another 10 to 12 months,This is really discourging when you are trying to build an engine as per WW's reccomendation using his his proven tested parts.I am to the point now that I wish I had gone Continental and I would not have had a problem with parts or part suppliers.Ted StoneTrying to complete a Corvair Pietenpol**************A Good Credit Score is 700 or Above.

Hi Bill,If you don't already own it, one of the books you should get if you aregoing to build a Pietenpol is the 1932 Flying and Glider Manual (availablefrom EAA). It has the original plans for the Air Camper and is aninteresting read. Chet Peek's book on the Air Camper is also fascinating,if you are interested in the history of this craft.While on the subject of books, if you don't have them, be sure to get a copyof the four Tony Bingelis books, The Sportplane Builder, SportplaneConstruction Techniques, Firewall Forward, and Tony Bingelis on Engines.Nearly every question you will come up with while building this airplane isanswered in one or more of those books.Welcome to the list! I enjoyed meeting you at the EAA meeting last week.Jack PhillipsNX899JPRaleigh, NC _____
