Subject: Re: Pietenpol-List: tail wheel springs/chainsIn a message dated 3/7/04 6:57:38 PM Central Standard Time, djv(at)imagedv.com writes:>DJ, I don't like the thought of tailwheel nicopress on primary flight control cables, so the way I did my cables, was to nicopress the cable / thimble right to the springs, and installed the springs through the holes in the tailwheelhorn, and run the 1/16" cable all the way up to the rudder bar. The springs are lightweight type, that when you pull the ends, it compresses (as opposed to stretching) the spring. I don't recall what you call that type of spring. The cables penetrate the fabric on the bottom of the fuselage, pass through a hole in a hardwood fairlead block (epoxied in at the station just ahead of thetailpost) and almost a straight line up to through the rear cockpit. I ran them through 24" lengths of nylon tubing in the rear cockpit, at about 1" each side of the torque tube, and secured each of the nylon tubing to the floor,in 3 places with Adel clamps. The cables / nylon tubing approximately align with the height of the rudder bar, where they pass through the bulkhead betweenthe front and rear cockpit. I attached the cables to the rudder bar at 3 1/2" R.B.L. (right butt line), and 3 1/2" L.B.L. using fittings that I made up out of a 1" length of tubing that had an I.D. of the O.D. of the rudder bar. I welded a pair of toungsto the this 1" tube, then used a hack saw to cut a slit in the 1" tube, betweenthe toungs. Drill a hole in the toungs for a bolt, and it now acts as a clamp on the rudder bar, as well as another hole for the cable / nicopress. Iattached everything up at the rudder bar, then did the final nicopress at the spring in the back...no need for adjustment. It's light, simple, and has so farworked flawlessly. I've got a leak in one of the master cylinders under the front seat, and tomorrow I'll take some digital pictures of that area. The pictures will also show the slick way I built my brake pedals / master cylinders. There's a lot of stuff going on under that front seat !!Chuck Gantzerstill working some squawks________________________________________________________________________________
