Pietenpol-List: Landing gear

Post by matronics »

Original Posted By: "McNarry, John"
There has been a lot of discussion lately regarding landing gear position.I find that I'm still as confused as before.I would like to know where the gear should go assuming the following:1. Long fuselage2. Wooden landing gear3. No brakes4. Continental A-65If you say "Follow the plans" then my next question is: Which plans?The 1932 plans give a different location than the 1934 plans. And the longfuselage plans don't give an axel location.Also, what are you using for a reference location from which tomeasure?Greg Cardinal________________________________________________________________________________

Subject: Pietenpol-List: Landing gearI'd like to write a short testimonial on the straight axle landing gear forthe piet. I have the traditional wooden gear with wire cross bracing with aone inch diameter straight axle mounted in motorcycle wheels with mechanicalbrakes. I now have 104 landings on this gear and feel that it is remarkablystrong and effective. Without an dual instruction in a Piet available, Isimply started flying my plane (I have 200 hours tailwheel time). It's easyto fly but has a pretty high sink rate when the speed drops off just beforetough down and early on I hit pretty darn hard, probably dropping it from 5or 6 feet or higher several times attempting to do 3-pointers. I've had totighten the wire cross braces once. Otherwise the gear has taken everythingI gave it. Several people at the local airport that thought I was crazy tobuild this antique landing gear system now sing its praise. Although I canthree-point it just fine now, I usually wheel land simply because it is funand very gentle on the airframe.Incidentally, the mechanical brakes won't hold for a runup but are veryadequate otherwise. The plane slows on pavement rather quickly in a 3-pointstance. The motorcycle wheels show no signs of strain even though I neverrespoked them on a wider hub. I haven't done a lot of cross wind landingsand haven't done a ground loop. In a parking lot I did do severalcookies--tight circles approximating a ground loop. Everything hungtogether. Just thought some of you might be interested.________________________________________________________________________________

John, I operate my brakes--mechanical--a lot like you might guess, withcables. The key part, of course, is where to locate the pedals in alimited space. I located them close to my heels to the inside--just abouthalf way between the bulkhead and the front edge of the passenger seat. Ihave to cock my heels inward a bit but am able to keep my feet on bothrudder pedals while applying the brakes. The cables come straight backalong the floor and have the major curve of the cable outside as they headto plastic ties along the rear wooden gear support. This is easy to dosince I did not cover the plywood floor with fabric on the outside. Thisalso allows easy inspection of all bolts in the torque tube.>>> John McNarry 12/09 7:34 PM >>>Thanks WilliamThat's a great testimonial to the gear design!

Hi Gang,Why not put rudder pedals in the rear cockpit instead of therudder bar? I know the plans show a rudder bar in the rearand pedals in the front, but when I built mine thirty years (+)ago, I reversed this by using Cub J-3 pedals in the rear andthe rudder bar up front. The main reason was that I was usingmechanical brakes with heel pedals and concluded that theywere easier to operate with rudder pedals, having a feel simi-lar to that of a Cub or Aeronca Champion.There never has been a problem with this setup. The wheelsare Shinn 6.00 - 6 from a Taylorcraft and they are lightweightones with good brakes. If I were to do another Piet with heelbrakes, the rudder pedals would still be in the back.Since I was installing brakes, I moved the main wheel axlesabout three inches forward from the position shown on theplans. Again, I would not change this if I were to build anotherPietenpol. It is a long time ago, but I seem to recall BHP re-commending this if brakes were installed. (My aircraft has theso-called "short fuselage" with the firewall six inches furtherahead of the position for the Ford engine; this, too, was re-commended by BHP himself for a Continental engine instal-lation.) I hope this info. is useful to the group.Cheers,Graham Hansen (CF-AUN)________________________________________________________________________________

Is your Dad building the split gear or the Jenny style gear with thestraight axle? The axle shaft for the Jenny style gear is made from a 611/2" legnth of 1 1/2 by 12ga. 4130.I have heard a good reason to use the rudder bar. If the pilot inadvertantlytips the airframe on its nose or comes close to doing so he will likely putboth feet hard on the bar. Its pivot point will take the load with outadding any strain on the rudder hinges and cables.John Mc-----Original Message-----

In Pete Bowers "Guide to Homebuilts", he has a diagram that says the contactpoint of the tire in level attitude should be not greater than a 20 degree angleand not less than a 12 degree angle forward of the C of G. Keep in mind you needto determine the verticle CG as well as the longitudinal CG.John McNarry wrote:> Graham and group,> Since there are so many variuos versions of the basic design.

Dennis,Make a full sized angle drawing on the workbench, to get the length of eachside of the "V" right, and the end of the lengths fall at the right spacingapart where they connect to the fuse. Now this is the pattern you areshooting for.I borrowed a "chop" saw from a contractor friend. Like a miter saw, but formetal with a fiber disc blade. Believe me it would be worth it to rent onefor a day, cause they cut so nice.Now get some scrap pipe that you can cut and keep adjusting till you get theangle just right. Cut in the center and turn one and stick them together. Can even go to Home Depot and get thinwall EMT conduit,,,very cheap.Leave the pieces a little long so after you weld the V, you can make thefinal angle cuts on top where the hinges are welded.As for the axle, This is one of the few changes I made to my Piet. My APdidn't like the way the axle was welded to the side of the legs with theweld in tension. Instead I removed the V point after welding and shaped around notch that would sit on top of the axle. The axle extended in pastthe legs a few inches . This was notched and opened to recieve the bracketto attach the bungee tube to.I'll send you a few pics direct.walt----- Original Message -----

Post by matronics »

Original Posted By: "Malcolm Morrison"
Subject: Pietenpol-List: Landing gearHello Chris: I built the plans gear with the cross shock struts andbungees at the top. After building the the shock struts the second timeit dawned on me that I could have made the chore of installing thebungees so much easier by building these struts J-3 style--turning thelower 1 1/4" cross tube 90 degree to the top one, then welding it at thesame distance from the top cross tube as the J-3 Cub. Then you can useoff the shelf J-3 bungee cord rings and install them in seconds with ahome made tool, rater than mess with the single 6' piece cord.Installing that 6' cord has been discussed on the list before, and itsounds like a real pain. I thought this was an original idea I came upwith, but I've seen several Piets at Brodhead with shock struts builtthis way. On building the gear, I built a cradle fixture the same withand shape as my fus. bottom. This allowed me to build the gear "on thefuselage" without actually building it on the fuselage, I tack welded ittogether, than had a friend mig weld it. ( The wood kind of takes abeating ) When finished, I moved it to the fus. for fitting. You willneed to move one gear leg foreward 1/16", and the other back 1/16" togive you 1/8 gap where the shock tubes cross each other, other wise theywill hit and rub on each other. Then drill your holes. Getting yourfuselage on the gear is a real physiological boost and a major turningpoint in your building. You didn't ask for all of this, but you got itany way. Good luck. See you at Brodhead. Leon S. Soon to move into ahouse with a real garage!________________________________________________________________________________

Subject: Re: Pietenpol-List: the myths about rib stitchingI did my rib stitching by myself. To reduce the number of trips from one side of the wing to the other, I made 15 straight needles each about 8" long. After marking and punching stitch locations, I ran all needles through the wing,along one rib, went to the bottom side of the wing and ran them all back through the wing. Then I went back to the top side and tied starting knots at eachlocation (the Polyfiber manual speaks approvingly of using all starter knots).Then I proceeded to the next rib and did the same thing....Carl Vought________________________________________________________________________________

I tried looking up owner-opinions on the 196 at www.epinions.com, but there are none.Does anyone have any experience with the 196 and if so, how do you like it? http://www.airnav.com/airport/5TA6#note ... ___Subject: RE: Pietenpol-List: Portable GPS opinion needed (Garmin?)Date: Wed, 15 Dec 2004 15:09:08 -0000

After spending the better part of the last 3 weeks here in sunny Flrebuilding the 4130 (cub-like) landing gear on the wrecked Piete I boughtlast summer, I have to agree with the experimentation part. Heck, there'sprobably a dozen good ways to build this gear faster and stronger than theoriginal plans. So at the risk of being shunned by Piete purest, I'd liketo suggest the following to any new builders: take a good look at the waythe Vari or Longeze gears are built and attached. These fiberglass gearscan easily stand 4 Gs on a 1000 lb airplane. They would not have to be asheavy for a Piete. Would be easy to build over a 4'x8' plywood "mold" withunidirectional s-glass fibers and epoxy. They could be attached bybuilding bolt ear tabs on the bottom of the longerons, attach via a 5/8"4130 tube glassed into the top of the gear and attached to the plane with1/2" bolt thru the tube and bolt ears. For the purest- you could paint theepoxy/glass spring gear with simulated wood paint. You could buy acomplete gear from Featherlite in CA for about $600. or build one for about$200 not counting the wheels.Gordon BowenOriginal Message:-----------------

Hey LeonI know winters get a bit long, but when you start thinking about skining a Piet in aluminum its time to take a vacation or change brands of tequilla. Or check your carbon monoxide detectors for a reason for such thinking. Save that kind of talk for April 1.Dick N.----- Original Message -----

Leon Stefan said:"This part is insane and I will never do it, but I would love to build a Piet. in all aluminum."My reaction is "Why not?"In fact, I seriously considered doing so some 25 years ago, but had too much on the go at the time to get any further than the idea stage. Nowadays, I'm too darned old and no longer have a workplace large enough for such a project.However, I wasn't going to skin the a/c with sheet aluminum. Too heavy. Fabric is lighter and would retain the authentic(?) external appearance. The intention was to substitute aluminum alloy structural members for the wooden parts of the original design. These would havebeen standard extruded sections and formed angles, channels, etc. riveted or bolted together according to standard aircraft practice.At first I considered an all-aluminum fuselage with fabric covering, but had settled on a welded steel tubing truss before the whole idea was shelved. This creation would have been "all metal" rather than "all aluminum".A spring steel landing gear was never considered because the highly localized loads on the structure would have required much re-design--besides altering the appearance of an airplane that was supposed to mimic the Pietenpol.The primary motivation for the exercise was to use a substitute material for scarce (and expensive) aircraft quality spruce; the secondary goal was to perhaps save some weight. I still regret that I never had the time to follow it through.Happy New Year!Graham Hansen(My Pietenpol, CF-AUN, is a standard wooden version)________________________________________________________________________________

Grant,Think the key reason for not building the Piete out of Al has to due with metal fatigue. As you probably can feel, the fuselage flexes a heck of alot every time you land. My Quasi-Piete is made out of 4130 and I can feel the flex every landing, especially if I don't make a smooth landing and let the tail down slowly. Secondly, one of the reasons the firewall is not AL has to do with the burning nature of AL. Boeing and other big guys have AL longerons and spars, but the structural I-beam design accounts for the flex fatigue of the metal. I've broken enough Al lawn chairs in my day to know I'd be really cautious about making Piete longerons out of AL tube.Gordon----- Original Message -----

I'm way ahead of the game.I took my last drink of of demon hard liquor Jan. 29th of 07- 11 monthsago. Perhaps I need to start up again. I'm not much of a beer drinkerbut I usually fill up a cooler with beer for Brodhead and Oshkosh--gotto keeo the strength up for all the walking! I just had 12 days withoutelectricity a couple of weeks ago and had plenty of time to think aboutthe all aluminum Piet again. Another reason I probably won't build itis because I just spent $800 of Pietenpol money (Covering supplies) ona generator so I won't be caught in the cold and dark again. The priceof living in the country Grahm: It is fun to dream. Gordon: I've considered the stress on al.stingers, but also have noted that several designs like theWW-1Aerodrome Aeroplanes are built with al. tube (Piet style) rivetedtogether. One of their airplanes (Nieuport-28 ) is heavy ( #1212 gw. andRotec radial) But it's a moot point since I 'm 95% sure I won't do it.Ken Chambers: I have 4 pictures available that have been posted before.I'll re post them. I have web Tv. which is what Fred Flintstone used, soI'm limited t what I can post. The pix. don't show much detail, but Igot the disc brakes from AS&S for 3/4" axels. I bought an ATV magazineand looked for a company the made wheels. While looking at atv. tires atWalmart I decided 21x12x8 would look ok so asked Douglass about makingme a pair with only the center boss hole drilled. (I forget the size. Ithink they are 1 1/2" ) then had my brother drill for the lug bolts onour mill. The wheels are 2 piece welded together. Each half comes invarious depths, your choice. I chose 3'' inner and 3"outer for 6" with.The pictures I have will be sent next. If you have any other questionsplease ask. There also is a picture of the inside beef-up structure forthe Kerri Price front door. Leon Stefan In KS.________________________________________________________________________________

Hi guys, Due to a change of plans I will not be starting a Piet project and all myparts are for sale. I have a Charlie Rubek built set of ribs including fourextra ones as I was planning on extending the wingspan by four feet. All plans, and a set of gear mount brackets for a straight leg setup.$450.00 for all.Those that have Charlies ribs know what a work of art they really are.

I also know that 'no' cannot be changed to anything else, ever, so don't bother trying.Don- take your flight review in the Piet.

For the last several years, my BFR has been in the GN-1. My instructor, who is also an FAA flight examiner and on my GN-1insurance policy, loves to fly in the plane. We don't have an intercom system worth a hoot, but between hand signals andsome occasional yelling, we get the job done. Makes sense to use the plane you plan to fly exclusively as the one for the twice a year proficiency exam. Oscar is right,the examiner/instructor love the change of pace. I can't wait to get my plane from Dallas to Corpus Christi where I nowlive. It will be great to fly down the coastline.Mike KingGN-177MKCorpus Christi, Texas ----- Original Message -----

OK, I'll start.My tailwheel is almost finished and I decided to add the steering horn,rather than rely on brakes for steering. I understand, and have seen manyphotos of, attaching the tailwheel horn to a rudder horn with springs, but Iwish to attach mine to the rudder pedals. What options can you offer, assuming that there are two choices: Run aseparate cable all the way to the rudder pedal; or somehow link up with therudder cable?Thank you,Gary A.
