Was my first flight in a Piet and it was better than I had imagined...love that Model A engine! I have been giving the powerplant a lot of thought as I prepare to build and was concerned about the weight issue. Actually I have 2 Model engine blocks and a ford 2.2 OHC(LIMA) engine that's brand new from during the Pinto years. It would be nice to use either powerplant format but concerned about the weight Vs hp ration in hauling my big self above the trees on a hot day. Interesting to learn that the Model A engine had enough go to get the pilot and a 250 lb passenger into the air with no trouble on a 90 degree day. Looks like more consideration is necessary in utilizing the what I have available, as in the true to form and design considerations of Bernard!

He used 1/8" inside the cockpit for the elevators, but behind the bellcrank he went with 3/32" He also used only 1/16" for tail bracing. I think a lot of guys go overkill and use 1/8" on everything. I have heard Bill Rewey say to use 3/32" on the tail bracing because if it corrodes you may not see it. I think if you go with stainless cable you would not have to worry about that. Besides there is an automatic fail-safe in that area because you have two brace wires on each side. The plans call for 3/32" for the ailerons.

Landing gear uses dash 22 turnbuckles and 1/8 cable.

La Crosse, WI ________________________________ Message 5 _____________________________________ Time: 09:23:56 AM PST US From: "Catdesigns" Subject: Re: Pietenpol-List: Photos For the control cables the plans call for 3/32" wire from the bell crank to the tail, 7x19 3/32" = 1,000# galvanized or 920# stainless an AN130-16 (1,600#) would be fine here. Some people do not like the small size of the 3/32" so they substitute 1/8" wire, 7/19 1/8"= 2000# Galv or 1760#. You could use an AN 130-16 and get 1,600# or if you step up to the AN130-22 you get 2,200#. Both exceed the design strength, you can decide how much you want to exceed it by. The two cables from the stick to the bell crank are called out as 1/8" flexible, so obviously an AN130-22 should be used here as you would be giving away 400# of strength using the AN130-16. Tail brace wire is 14 gage on the plans. According to my book "Aircraft Maintenance" by Brimm and Boggess published in 1940, Tinned Aircraft Wire 14 gage has a breaking strength of 1,250#. Unfortunately, this falls between the 3/32 and 1/8 cable. I believe most people go with the 3/32 with AN130-16. It's what I will use. The Jenny gear calls for 1/8" cable so use an AN130-22 which exceeds the strength of the wire, an AN130-16 would be too much of a loss in strength. I know the list archives have a lot of discussion on this subject. Try doing a search and you can read what others have done. The photo share can take several days to post as Matt does it by hand when he gets time.

It got me to realizing that there are quite a few Pietenpol owners in Ohio. If you've done some research Tim you probably know this already. There's Mike near Cleveland, Will Graff in Wadsworth, Frank Pavliga near Alliance, Gary and Shad Bell near Columbus, Virgil Phillips near Mansfield, and I'm on the eastern side south of Youngstown. These are just some of the completed ones, I'm sure there's more. I'm sure there are several under construction. Josh Bixler is another 20-something builder near Alliance. I guess what I'm saying is there is a lot of Pietenpol activity in Ohio. It would be really cool if we could try to organize something to get at least a few of them together somewhere. I know when I was building it helped so much to see one in completed form. Anyway if there is anyone that is going to be in the northeastern Ohio you would be very welcome to stop by and take a look and talk Piets. Just drop me a line. Don E.

After looking at Chuck Gantzer's web site, I then e-mailed him to get more of his thoughts. I'll attach Chuck's comments below that he shared with me yesterday and he also commented to me to post the question again as you just did. From Chuck: John, I used 1/8" cable for the rudder control, but I just looked at the plans, and it calls out for 3/32" cable, but I think almost everyone uses 1/8" for the rudder. Also use 1/8" for pitch control from the stick to the bellcrank, and use 3/32" cable from the bellcrank to the Flippers (elevators). In the book Stick and Rudder, Wolfgang Langewiesche calls them the 'Flippers'. He goes on with a very good explanation why. I would strongly suggest you read this book at least Three times !! In the AC 43.13 (another Must Have publication) it calls out for a cable deflection of more than 7, there should be a pulley in place, as opposed to a fairlead. Therefore, by today's standards, a pulley would be required on the cable that goes to the top of the bellcrank, like you suggested you were going to do. However, because of the design of the Pietenpol, and the tension of those cables, the pulley is not required there. On my plane the aileron cables are 3/32", the drag / anti-drag cables in the wing are 3/32", the lift strut cables are 3/32", the cabane strut cables are 3/32", the flying wires on the tail are 1/16", and the tailwheel cable is 1/16" which goes all the way up to the rudder bar. I used nico-press fittings for everything on the cables, except the flying wires on the tail, which are swaged fittings. The control surface cables are NOT tight...you simply remove all the slack, and do not tighten up the cable - just remove all the slack. On the fixed cables in the wing, struts, cabane, and tail, you DO tension them up a little bit, till they Twang - no call out on tension, but they are tight. The entire cable system on my plane has been trouble free, however, there is times when some adjustments must be made. Wood changes dimensions slightly with temp and humidity, and this makes it necessary to make an adjustment here and there, every so often. A thought just occurred to me. If you like, you should ask me these questions on the Pietenpol Discussion group, so anyone else contemplating the same things you are, could benefit from my explanation. Hope this helps. Have fun building !! It's a Great hobby !! Chuck G. NX770CG I'll offer this infomation to the group so they don't have to look at the prints: According to the prints (2-26-34) of the control system, 3/32" cable is called out for the rudder cables (top view of fuselage detail), 1/8" cable is called out for the cable between the control stick and bell crank (side view of fuselage detail), 3/32" cable for the aileron cables (cross section view of the fuselage and wing detail). I don't see a call out for the cables running from the bell crank to the tail surfaces, maybe it's on a diiferent page? I'm wondering if 3/32" cable is a good choice for the control stick cables? Would the control sticks and other parts fail before the 3/32" cable fails? Thanks all.

Just never done it with aircraft plugs before. Our EAA Chapter has plug cleaning and gapping tools so no problems there, but I'm trying to debunk the lore about keeping each plug in the same position when reinstalling, or else rotating them. I have John Schwaner's Sac Sky Ranch book and it talks about rotating the plugs on 4-cyl. engines, but then seems to indicate that it should not be done on 4-cyl. engines where one mag fires all the top plugs and the other fires all the bottom ones. If I need to keep track of the plugs I will, but I figured if anybody would know about this, you Pieters would. Any comments on spark plugs?

Oscar Zuniga Oscar, Yes, the plugs should be rotated, but I don't recall the document that calls out the rotation. I think you rotate each top plug over to the next cylinder on the bottom, and so fourth for the bottom plugs. This way the plug gets a different cylinder, and a different mag. Chuck G.

I know Mike said he would not be able to make it. I believe it is on the week end of august 26, and 27. Marion is a nice "central" location for all in Ohio, and weather pending, would make a nice cross country. I plan on flying NX92GB to marion if we get our carberator parts in time. Hope to see some Piets at marion since I didn't get all the way to brodhead this year. sincerly Shad Don Emch wrote: --> Pietenpol-List message posted by: "Don Emch" I was just reading Tim Hansens post.
