Hi Pieter's,It's been a while since I have posted anything on the list. My main computer crashed and it took ages to get it running again. I checked the email account and there were around 700 emails waiting...mostly junk. However, amongst them all, I a found a mail from Jim Markle that he sent in January of this year. I have just sent a mail back to him a day or two ago apologizing for taking so long to get back to him...a 6 1/2 month later response time is a bit too long I think!Anyway, things are quiet on the Pietenpol front over here in Japan land. Both my friends Piet and mine have been dormant for quite while. Things are crazy busy at the moment and have been that way for a fair while but, I still fly my little r/c Piet to keep my sanity. That little model is now almost 14 years old.....and still going strong! Long live the Piet!Presently I am trying to learn gas welding in the hopes of being able to make up the metal fittings etc for my project.......I am a slow learner so even that may take a while!Well, just wanted to say g'day to everyone on the list and hopefully I can get on with the project sooner rather than later!Cheers to everybody!Mark StanleyJapanRibs done, fin/rudder done + a pile of sticks________________________________________________________________________________Subject: Pietenpol-List: Re: Balloon tires?

Hello Good Pietenpeople!I an considering replacing the mid-70s skinny motorcycle tires in my Piet Air Camperwith the big balloon tires that Bernard had on a couple of his, like the1931 Air Camper 12236 with the 65hp Velie engine that can be seen here:http://www.pietenpolaircraftcompany.com ... o-galleryI think they are also on the Allen Rudolf Air Camper.They look to be maybe 16 to 18 in diameter. Does anyone know anything about thesewheels/tires? Thanks,JeffRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Steve;I have had both a taper shaft hub (A65) and a flanged hub (A75) on NX41CC and havehad props for both. On the taper shaft hub, there is a shaft that comes forwardthrough the prop and that shaft secures to the prop by a flange that isbolted to the face of the prop. On the flanged shaft, the flange on the noseof the crank does not have an extension through the nose of the prop. It hasdrive lugs that engage counterbored holes in the aft face of the prop and theprop bolts pass through the crush plate and prop into the threaded drive lugs.I don't know what your buddy is concerned about, because people who have orwant older airplanes with these engines are very aware of the differences betweenthe hubs and how to fit props to them. I have never heard anyone mentionanything like, "that's a taper shaft hub, I'm going to pass on it because I can'tfind a prop to fit it". The prop makers will bore and counter-bore yourprop as needed to fit either one.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Balloon tires?

Jeff; you might investigate the 'Dico' tires that a lot of the light planes like the AirBike have used and are using. I don't know who currently owns the design and markets them (maybe Titan), but they are balloonish tires with a 4 ply rating, a load range suitable to ours, and an "S-turn" tread pattern on them. Although they are not as tall as 16" or 18", they are sort of chubby and the price is quite reasonable. You can see them on my M-19 "Flying Squirrel", which is the airplane on the right, here: http://www.flysquirrel.net/hangar.jpg . The tires on my Air Camper (on the left in the picture) are 6.00x6 "Aero Trainer" tires, very good and very available at about $75 for just the tire, and you can see that the Dico turf tires are just a bit fatter and taller. For another possibility, you might look at the "Aero Classic" tires, which are meant to mimic the Stearman tire. Aircraft Spruce has the Aero Classic All-Weather and the Diamond tread, not cheap, although I think you are looking for the tires with just a straight groove tread. Nowadays the best cross-reference is going to be a turf tire like the golf carts use, or an all-purpose ATV tire.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

The only problem with the tapered shaft hub (and I've owned 3 of them) isthat the hub is a separate part to be purchased. If you can find a NOS(New, old stock) hub they go for somewhere around $600. The hubs are proneto cracking and if you find an old one to buy, you should have itmagnafluxed to ensure that it is not cracked.The nice thing about the tapered shaft is that the propeller can be removedvery easily and quickly from the engine. The hub is simply unscrewed fromthe shaft and prop and hub are removed as an assembly from the engine.Jack PhillipsNX899JPSmith Mountain Lake, Virginia-----Original Message-----
