For those who havent seen my Harley wheels in the past, I'm enclosing a pic. TheHarley spokes are much heavier duty than Honda or Yamaha. In addition thehub castings on the Yamaha 650 wheels that I originally built, had a lot of defectsthat I wasn't comfortable with. On my other Piet, I made a very bad crosswindlanding last summer and bent the axle but the wheel held up fine. I ampresently re-building the axles for both planes and will have the axles heattreated and drawn.Dick N.________________________________________________________________________________

Are there any spoke motorcycle wheels that have large enough hubs to be machinedto fit on 1 1/4" diameter axles? I'm fed up with trying to get the ancient old6" wheel brakes I have to work- they're the old expander tube shoe and drumstyle and I think need more volume than the master cylinders I have can produce.and if I change anything at this point I'd much rather go with spoke wheels.yet I want to keep the Cub gear legs I have.and not alter them if possible.Ihave no problem with machining hubs for brass bushings, and mechanical drumbrakes would be OK too if I found a set that could be altered to fit.

Raymond,I used Harley Sportster wheels from www.paughco.com, that had been modifiedto fit 1" bearings...that's the largest I could find. I stepped down the 11/2" axle with 2 steps, the final one being 1" solid, about 18" long. Goodluck....Gary from Cool-----Original Message-----

Raymond This is what Wil Graff did on his Piet The wheels used on my Piet are older (1970s) Suzuki 250 or 400 dirt bikefront wheels. I also used the same brakes , cables, and handles. The wheelhubs were drilled out for brass bushings to fit a 1.25 " cold rolled hollowaxel. The 1.25 diam. axel was machined for a hot -cold shrink fit on mainlarge axel. The hand brakes and wheels are doing just fine. The axels arelubed with never- seize grease.Wil GraffYou can see his plane herehttp://westcoastpiet.com/images/Will%20Graff/pictures.htm I believe Alan James used 60's vintage Triumph motorcycle wheels with asmaller axel http://westcoastpiet.com/images/G-BUCO% ...

Pietenpol-List: Re: Spar problem
Original Posted By: "Don Emch"
Hey guys... I'm kinda freaking out a little..i built a one piece wing.. with solid 3/4 inch spars..my right rear spar outboard of the strut attach point has warped a bit..it moved down at the tip about a half an inch..it looks even more exaggerated atthe trailing edge.i can lift the wing tip and make it all line up..i assume they all have a bit of flexibility outside of the strut attach pointI'm thinking i need to cut the spar and splice in a new section that is straight..my other thought was maybe way off.. 43-13 allows a plywood doubler to be attachedto reinforce a crack in a spar..i wondered if i could jack up the wing tip and add a piece of 1/8 inch plywoodto the rear of the spar to keep it in place.. from just inboard of the fittingto the tip... once the glue dried the ply should stabilize the spar and keepit from moving down again.. i'm afraid splicing in a new section may be the only hope.. but i wonder if airloads move the wing much..jeff :(Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Spar problem

Jeff...Do you think you can lengthen the right rear strut and take care of the problemby adding in some washout. The wings can really flex quite a bit. I realizethe problem is outboard of the strut, but maybe you can move it up enough tocancel out that down warp.Don EmchNX899DERead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Jeff,Exact same thing has happened to my left wing. It doesn't take very muchpressure to straighten it. Before varnishing, I supported the spar on bothends, sprayed about 1 gallon of water on it, allowing it to soak in forabout 30 seconds at each pass, and then hung about 50 lbs of weight at thecenter. That was plenty to pull the warp out, so I let it dry for severaldays. After removing the weight, most...not all...the warp had disappeared.It's varnished now, and has been hanging in the ceiling for about 2 months.Tomorrow I'll be bringing it down for fabric and will know if the fix stuck.I'll let you know....Gary BootheNX308MB-----Original Message-----
