Pietenpol-List: solid wire vs cables
Original Posted By: santiago morete
Bill, I think I printed out the details on how to make a jig for forming the hard wire loops and ferrules for the Piet tail feathers and could probably locate them in my stuff, given time. If memory serves, Keri-Ann Price authored that article for BPA, including photos and details.Be prepared for flak though... the idea of using hard wire braces with wrapped ferrules got shot at pretty hard last time it came up here. Recognizing that braided aircraft cable, Nicopress, and turnbuckles are all available and commonly used, the nifty and nostalgic idea of stiff wires seems to have been swept away in the sea of modernity.Oscar ZunigaAir Camper NX41CCSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________Date: Tue, 25 Mar 2008 15:44:16 -0300 (ART)

Santiago,Those were two very interesting links that I had never seen before. Lots ofgood information.The one for the drag wires uses nico-press sleeves in place of wire ferrules- very interesting.By navigating a bit around the Flitzer site, I found a link to a companythat fabricates drum brake assemblies that look like they would go great ona Pietenpol. The design apparently incorporates an arm to prevent rotationof the axle when brakes are applied. The only downside that I can see is theprice - about $2000 a pair! But they also sell detailed construction plansfor the brakes.Thanks for the tips!Bill C.________________________________________________________________________________Subject: RE: Pietenpol-List: flaperonsDate: Tue, 25 Mar 2008 16:57:21 -0400

wait, wait, wait! All of you guys have talked about AD rivets!!!!!!!! The plans show steel rivets, NOT aluminum AD rivets. Steel Rivets do not swell in the middle when peened over, nor do they tend to work loose. Whether you want to use them is a different question, but make sure you have the right thing in mind when you make your decision.Gene ----- Original Message -----

the jig for making the loop is pretty simple and the drawings for it are pretty common. What is not as common, or as easy, is making the wrapped ferrule. I know a couple of people who are proficient at making these ferrules, but it is not easy to describe or do. Don't forget, another option to !gasp! nicropress fittings is wrapped and soldered, which is simple and authentic as well.Gene ----- Original Message -----

Corky asked-> It was stated that the wing drag and antis were double piano wire. No gauge> was given. Do you have any info on that?I looked at the 1932 Flying & Glider Manual plans as well as my set of the "Improved"plans and the drag/anti-drag wire braces in the wings are called out asdifferent things there. The F&GM has them as 3/32" stranded cables (0.094")while the Improved drawings call out 13 ga. hard wire.No idea which wire gauge was used for the hard wire callouts; you can search thearchives to see that there have been various different ones theorized but themost likely are the AWG (Brown & Sharpe) or the Washburn steel wire gauges.#13 in AWG is .0720" and in Washburn it's .0915" so they are both close to the3/32" cable diameter but no telling what the strength difference might be.I find no reference anywhere to double piano wire and there are many differentmusic wire gauges... check here:http://www.sizes.com/materls/wire_music.htmCuriously, the callout for the tail brace wires is also different between the F&GMand the Improved plans. The F&GM (older) calls for #12 hard wire bracingand the Improved (newer) calls for 14 ga. hard wire. So depending on which wiregauge was used, that's a variation of from .0641" (#14 AWG) to .1055" (#12Washburn wire gauge). Probably due to the availability of wire at the time, aswell as Mr. Pietenpol's experimentation with different materials as he refinedthe "kits" and the design, as well as the plans. As with many things on thisairplane, the only thing that is standard is that it's non-standard ;o)Oscar ZunigaAir Camper NX41CCSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________
