Pietenpol-List: Re: torque tube question

[matronics]

Original Posted By: Kip & Beth Gardner
I have seen a number of people talk about putting a shim under the forwardtorque tube bearing to raise it up off the floor. I always assumed thatthis was because the torque tube touched something, most likely where itpasses through the back of the front seat between the "V" formed by thesquare spruce diagonal braces. Is this correct?My torque tube sits flat on the floor at both the front and back endswithout a shim. It did touch slightly at the front seat back, but a lighttouch with a small sanding drum gave it clearance. My problem is that withthe interconnect between the front and rear control sticks, the interconnecthits the "V" brace on the side that it is on with what appears to be a verysmall aileron deflection.Have some of you had this problem? I am wondering whether the shim underthe front bearing may have been to raise the torque tube up so that theinterconnect hits the diagonal later, or maybe some of you have "jogged" theinterconnect so that it does not hit, or maybe whether the aileron travel Ihave is sufficient and I am worrying about nothing.Sound familiar to anyone??Gene________________________________________________________________________________Date: Wed, 7 May 2003 19:35:29 -0400

Sounds very familiar. I don't know how it ever worked in the plansconfiguration, but if you cross the interconnect from the left side of therear stick to the right side of the front stick, the problem goes away.I had to shim the torque tube a bit to keep it from hitting the ash crosspiece.Gene HubbardSan Diego-----Original Message-----

What I remember is that since the floor is "bowed", the attach point in therear and in the front is not on a flat plane. I had to put a "wedge" underthe front bearing to keep things in line, and to keep the tube from binding.Later after final assy, the connecting tube from front stick to back, rubbedunder the arch in the bulkheads. Had to get Mr. Dremmel into the act on thatone.waltNX140DL15 1/4 hrs down, out of 25----- Original Message -----

I can't believe it!! A really simple solution!!! By crossing theinterconnect from the left to right, it does not hit the forward elevatorcable?Gene----- Original Message -----

Mine doesn't. Then again, my torque tube came from Replicraft, and I neverfigured out which plans he used.Gene-----Original Message-----
