I built the wood landing gear per drawings and dimensions. The axle is 1.500" IDwith a 1.750 OD.How or where do I find a 40 spoke wheel to fit these dimensions???--------Tony CrawfordRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

I designed mine and had the hubs machined, then had Buchanan's make customspokes and lace up the wheels for me. My axle is only 1.500" Outsidediameter though, so those drawings would not work for you.Jack PhillipsNX899JPSmith Mountain Lake, Virginia-----Original Message-----

How about Harley wheels re machined for bushings instead of bearings. With motorcycle tires,tubes,steel rims,16"diameter. 32#each.

My wheels (complete with tires and tubes) weigh 25 lbs. apiece. And thehubs are 6" wide to help resist side loads on landing. The hubs aredesigned to accept Cleveland hydraulic brakes.Jack PhillipsNX899JPSmith Mountain Lake, Virginia-----Original Message-----

Very pretty! And a lot lighter. I do have a question though: if you had enough side load to worry about the wheels being damaged, wouldn't a ground loop follow and ruin your day any way?=F0=9F=98=A7=F0=9F=98=A9Sent from my iPhone> On May 19, 2016, at 10:38 AM, Jack Philips wrote:> > My wheels (complete with tires and tubes) weigh 25 lbs. apiece.

Not necessarily. By the way, I did groundloop mine during a forced landing many years ago, when the axle broke. The wheels were completely undamaged and didn=99t ever require trying afterwards. The axle was anither matter. I replaced it with one that has a .250=9D wall thickness and I had it heat treated to 160 ksi tensile strength.Jack PhillipsNX899JPSmith Mountain Lake, Virginia

Or just buy the nylon fairleads from Aircraft Spruce like Piper used for years. They are made to fit in a short piece of =C2=BE=9D tubing, which can then be welded to a plate that can be attached to your structure. I used them throughout my Pietenpol. Here=99s a picture showing how they are mounted:And here=99s a picture showing a closeup of the mount:Jack PhillipsNX899JPSmith Mountain Lake, Virginia

Tony,You say you built your gear "per the dimensions." The plans I bought from Doc M.are so bad I can't read the dimensions! If anyone can provide the dimensionsfrom Fig 6A, page 14.

Tony,I think perhaps you used the wrong detail for your axle. The FGM drawings callfor the axle to be 1 1/2" OD x 12ga chrome molybdenum. The axle collar, thatslips over the axle is drawn with 1 1/2" ID and 1 3/4" OD.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/imag ... ___Subject: Pietenpol-List: Re: Wood Landing GEAR

While we're on the subject of wooden gear, am I missing something as far as theaxle and bungee arrangement? I can't find anything on the drawings showing thecage or bracket that retains axle in case of bungee failure. I'm sure it's rightunder my nose, and as usual, I will probably realize the answer right asI hit the "submit" button...--------Jon JonesIronton, MORead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Wood Landing GEAR

Hey Jon,You're not missing anything, there is no "axle retaining" mechanism shown inthe plans. This, however, should definitely be added.As mentioned, most people use a cable look, BUT if you go that route, besure to make it sturdy and use a few nico sleeves if you use nicropresssleeves. I personally know someone who's bungee's failed on one side andthe "backup" cable slipped through the sleeve. Busted prop and an upsidedown airplane resulted.I made a "U" of thin aircraft tubing, flattened both ends and affixed it tosome of the AN3 bolts holding the lower "V" brackets together. Can't sayhow it'll work, but should be sturdy.Douwe________________________________________________________________________________Subject: Pietenpol-List: Re: Wood Landing GEAR

Rick/Douwe, thanks for the help. Just wanted to make sure I wasn't overlookingsomething in the plans. This looks like one of those areas where it might be funto get a little creative with engineering. Rick, in the photo you posted, I'mguessing the downfacing rod is both a guide pin, and to keep axle from rotatingwith brakes. I might try to come up with something that is both a safetycage and rotational stop. If I get some time I will have to look at ideas on WestCoast Piet.--------Jon JonesIronton, MORead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Re: Pietenpol-List: Re: Wood Landing GEAR

Jon,Your are right, the down tube is an anti-rotation device since this set up has brakes. The photo I sent is not of my plane, though my set up is the same, but of Mike Cuys. A little more elegant way to set up the "safety strap" in case of bungee failure, is a modification of the loop seen on Mike Cuys plane. This is similar to what Dowe spoke of, but still uses a cable.The photo is a nice example on Dan Helspers plane. I just used a loop, but that was done an hour before first flight last year. I will do what Dan has done using 1/8" or 5/32" 1x19 cable as soon as I can. I am sure it will be strong enough.Regards,Rick SchreiberNX478RSOn 1/7/2017 12:39 PM, wheelharp wrote:>> Rick/Douwe, thanks for the help.

For yet another version of the axle anti-rotation setup, go to Westcoastpiet.com , photos, and scroll down to John Dilatush's Air Camper pictures. Here's a good closeup: http://www.westcoastpiet.com/images/Joh ... 0049.JPGAs you'll see, John used a pair of short links with rod ends to form somewhat ofa "four-bar linkage" to keep the axle from rotating when the brakes are applied.In other photos there, you'll see that he also used the aircraft cable loopsto catch the axle if a bungee should let go.You will also find a photo of the motorcycle chain links that John used here andthere as cable shackles on his airplane. A pair of chain links and clevis pinsshould price out quite a bit lower cost than an AN115 cable shackle ($10.85each for 3/32-1/8" cables). Find a decent worn-out motorcycle chain, pressout the pins, and you can get the links for free.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 power, 72x36 Culver propRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________
