Pietenpol-List: leaf springs for tailwheels

Subject: Pietenpol-List: leaf springs for tailwheelsBryan,I started with one leaf spring and it wasn't enough resistance. Too much bounce andmy tailwheel steering cables were slapping the fuselage bottom. I added a secondleaf and the ride was much more stable in addition to the fact that if you only haveone leaf spring and it breaks....your tailwheel will damage your rudder or more.(I had one spring break on me at the 200 hour mark and thankfully the second spring saved the day)A J-3 setup I believe has 3 springs which may be too stiff a ride as the tailwheel weight on a Cubis generally heavier than most Pietenpols but you can see how it works out.I'm running a 6" diameter tailwheel I picked up from Wicks.Mike C.[cid:image003.jpg(at)01CCD202.5B33A2E0]________________________________________________________________________________

JackBeing on the EAA Board of Directors, I can tell you that this article is notentirely correct. Also since I am involved, I can't talk about (at thistime) details other than we are asking a couple of news agencys to correctthese botched reports like this one. EAA is a great organization and as aresult I have given them a lot of my time for the past 20 years. Serving onthe Board will give you a different outlook on what is involved to have thisorganization keep fighting every day to keep our flying freedoms. Sometimesthis economy dictates that the organization must not spend more that ittakes in (unlike our government) but the process of action that is stated inthis article is not correct.Barry DavisNX973BP _____

Wow.Just curious as to how a move like that would/could strengthen the organization.In my mind, one of the best things about Sport Aviation magazine is the talentedphotography of Jim Koepnick. Every issue seems to have "once in a lifetime"type photos taken by Jim (every month). Another head scratcher would be thedecision to eliminate the electronic publications department. In recent years,EAA has made lots of useful information available electronically. For instance,after ceasing publication of the printed version of The Experimenter, it wasbrought back in electronic form (only). I assume that will no longer be published.And providing EAA members with access (through the website) to the fullcatalogue of back issues of Sport Aviation, in my mind, is practically worththe annual dues. I hope they are not going to put an end to that. And the HomebuildersHelp videos are a very useful tool as well.I think the most puzzling statement is the following:"EAA spokesman Dick Knapinski stressed that the changes were made to move the organizationforward to better serve EAAs members and that they were not made asa cost-cutting measure." Please.How are the members going to be better served, if services are canceled, and fewerpeople will be left to provide the services that remain? And I find it a littlehard to believe that the laying off of a group of 30 employees is not acost-cutting measure. Are we then expected to believe that those 30 employeessuddenly stopped performing their duties adequately? Why not just be honest, andsay that expenses needed to be cut in order to survive?Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Subject: Pietenpol-List: 2.5 hour Piet DVD available For years I've had an old VHS tape that I dubbed and then dubbed to DVD's that shows thebuilding and flying of my Pietenpol. I haven't had DVD's available for a year now becausethe tape basically wore out but a local shop salvaged (with a moderate amount of tracking 'snow' in spots)it and I had a run of 50 made.The first 45 minutes shows a complete walk around of finished airplane. Next we do some fun flyingscenes over the farmland south of Cleveland, Ohio. Finally show photos and video of my construction,photos of other Piets, 1st flight, some of early Brodhead events, 1st time with the plane at Oshkosh,and more.If interested please send a check (don't do Paypal) to Michael Cuy, 16465 Heather Lane, Middleburg Hts. OH44130. $25 which includes 1st Class shipping. Again, there are portions of the DVD that DOES have snow and itcan be a bit distracting but overall the production is fine.Warning: Watching this DVD can induce drowsiness to non-airplane people. If you're lucky the DVD might evenclear out the room for you. This DVD can be used to make uninvited visitors, in-laws, outlaws, or people who justdon't know when to go home actually go home.Thank you,Mike C.________________________________________________________________________________Subject: Pietenpol-List: Re: leaf springs for tailwheels

Mike, Thank you. I had not yet thought about no backup if single leaf failed. The drawing is fantastic. I had been trying to figure out what the best mountingmethod would be. I am glad you sent it as I was getting ready to beef itup more and add unnecessary weight. Thanks, Bryan--------Working Piet N5289BWhile I may not always be right, I apologize well.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: 2.5 hour Piet DVD available

As Mike mentioned, the best setup appears to be a combination of two leaf springs.My original setup had a spring that was too stiff and not enough arch togive proper ground clearance. The original tail wheel was a Maule which was wornout and no longer was plumb with the aircraft causing some exciting momentson some landings.Replace the spring with one from ASS PN 0-614200 designed for a Cub. Removed theshort spring and fabricated a new bracket to accept the existing mount points.Replaced the tail wheel with a Matco 6" which proved to work very well withmuch better ground clearance.--------Adrian MWinnipeg, MBCanadaRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/dsc0 ... __________
