Every reference I have read says to use mild steel rod. I'm not the expert, but if it were me, I would use a rod type made for welding muffler pipe.Mild steel rod, as it is less prone to cracks from vibration. Also 4130 steel is in a class known as air hardning, and mild steel filler rod is much less prone to harden (due to low carbon) and crack over time.Bob>From: RBush96589(at)aol.com>Reply-To: pietenpol-list(at)matronics.com>To: pietenpol-list(at)matronics.com>Subject: Pietenpol-List: welding landing gear>Date: Sat, 8 Jan 2000 14:25:05 EST>>>Can anybody give me any suggestions on what kind of filler rod to use on >4130>chromoly if you are going to tig weld the landing gear?>> Thanks> Robert Bush>>________________________________________________________________________________

Do you have a short or long fuselage? I remember installing the second set of controls in a long fuselage and because the long fuse floor is a little less curved, the fit was different than in the short fuse. I had pre made the safety strap to the plan for the short fuse and had to remake it because the torque tube sat closer to the ash beam. This could be some of what you are experiencing. I know that built to the plans, the aileron will reach full stop before the controls hit. The amount of raising you suggested may be close to the amount it is lower if any of this true on you bird. My approach to this aircraft is somewhat different than most, I chose to build as close to the plan as I could interperet and manufacture, and see the out come. When the plane was completed, it amazingly worked as advertised and so I didn't experience many of the things I hear about which don't fit or work. Needless to say, I am impressed with the design overall, but I know there are differences between some installations on the short and the long fuse. There are two long fuses here with controls installed which I can check for this problem. I will do this tomorrow.

Hello Jack Phillips and group,You have me thinking about that link tube. Like you, I havenever heard of a buckling problem with it in a Pietenpol.The stick forces of the four different Pietenpols (includingmy own) that I have flown are very light, and this is probablywhy there have been no reports of a problem (as far as we know). However, as you correctly state, opposing inputs be-tween two pilots could buckle that tube. With this in mind, itcertainly is a good idea to go to.049" wall thickness.When the weather warms up, I shall take a look at mine to see if it tends to buckle with opposing stick forces. Over thepast thirty years I have had people fly from the front seat onmany occasions and never suspected there could be a prob-lem. My fuselage was built according to the blueprints for the"Improved Air Camper", and is shorter than yours. Likely the link tube is shorter too, and the tendency to buckle should be somewhat reduced. We'll see.Regarding moving the link tube 1/2" higher on the sticks, youcould wind up raising the front seat a bit for clearance. I'mnot sure about a clearance problem between the link tube and the rudder bar since I use rudder pedals for the rear rud-der control, but in any case the aileron travel is restricted bythe stick running into one's legs in the Piets I have flown---par-ticularly those with standard cockpit width (mine is two incheswider than the width shown in the plans). If you can, take a lookat a Piet with a rudder bar in the rear and see if there is indeeda clearance problem between the bar and the link tube.Thanks for calling this to our attention.
