    --> Pietenpol-List message posted by: "Carl Loar" <skycarl@megsinet.net> Hey Chris,, The wheels are 18 inch rears for a 650 yamaha. Nice and beefy with shoe brakes that worked well with my mechanical brake system. I had to open them up for the one and a half inch axle and machined my own bushings. They are really strong and I don't think I will have a problem with side forces trying to bend them.

    Subject: Re: Weld 4130 steel
    --> Pietenpol-List message posted by: Mike <bike.mike@verizon.net> Chris Tracy's admonition to avoid brazing 4130 should be underscored. Everything Chris says is true, save one. Many, if not most, steel bike frames are brazed, it's true, but those that are, even though they may be called "chrome-moly," are not generally made from 4130, but from some other high-molybdenum, medium-carbon, steel. Brazed bike tubing material generally is made with much more manganese than 4130, around three times as much, and less chromium. Bike frames that are successfully built with 4130 are rare, and either over-built or welded. I don't know if the manganese is what enables successful brazing of bike frame tubing, but a high failure rate is to be avoided, even if your likely outcome is "only" disfiguring injury.

    Subject: modified the rudder bar with GREAT results
    --> Pietenpol-List message posted by: "w b evans" <wbeevans@verizon.net> Just to let everyone know that with all my complaining about the rudder bar, I had to do something. Thought of putting my heels in "sturrups" to ride with the bar, but would be hard getting to the brakes. Besides it's uncomfortable. Desided to build the mod around the fact that I like to keep my heels on the deck and use the rudder with my flipper feet. So I picked a design and went with it,,,,I tried by putting some tubing cut to give a rectangle above the rudder bar that my toes could push on. This brought the top of the tube to about where the forward rudder pedals are. Made them 3" wide, and about 3 1/2" high, starting about 1" in from the center line hole of the cable connecting point on the end of the tube. This wouldn't interfere with the stops, or the seat, or anything. Anyway, if anyone wants more details, I'll send it to you. Now I can feel the rudders with my toes, and the landings are not a mystery, wondering if I'll make it OK. Now I have much better feel of the plane, and control on landing. "My toes were trained,,,my legs were not" I'm happy as a clam. walt evans NX140DL

    --> Pietenpol-List message posted by: "Gene Rambo" <rambog@erols.com> well, if you learned in a nose (training) wheel with toe brakes it was "keep your heels on the floor." If you learned in a tailwheel, it was "keep your heels off the floor and toes on the rudder." ;) Gene ----- Original Message ----- From: <Isablcorky@aol.com> Subject: Re: Pietenpol-List: modified the rudder bar with GREAT results > --> Pietenpol-List message posted by: Isablcorky@aol.com > > Great to hear this news.
