Subject: Pietenpol-List: elevator cable routing under the rear seatHello all, From my recent inquires, it's now obvious that I'm working on my controls. Today'squestion is: Do people still run the elevator cables thru the wood crossmember under the rear seat, or should pulleys be located directly behind therear seat to guide the cables from the control sticks up to the bell crank?If people still run the cables in that area without pulleys, are wear surfacesor some form of guides fabricated? Thank you for your help, John ---------------------------------See the all-new, redesigned Yahoo.com. Check it out.________________________________________________________________________________

Subject: Re: Pietenpol-List: elevator cable routing under the rear seatI'm working on mine now too. I used a pulley to run the line to the top of the bellcrank, but the line to the bottom of the bellcrank is almost straight, so I'm running that cable through a piece of copper tubing. I put an oak doubler under the rear of the rear seat support to give some strength to the hole the copper tubing will mount in. I have a tubing flare tool that I willl use to bend a nice flange on both ends of the tubing after it is in place. I got this idea from Tony Bingelis's books. I'm not finished yet so take it for what its worth.....Ben________________________________________________________________________________

Subject: Re: Pietenpol-List: elevator cable routing under the rear seatI made hard wood guides. I got the idea from an old timer at Brodheadwho said he did that many many years ago on an aircamper he still flies.The wood and cable show no ware, just a polishing from the cablemovement He said. I drilled the ash at a roughly at the angle neededfor the cables, then made the holes better with a Dremmel. I made anaccess cover under this area so I can watch it closely and put onpulleys if it comes to that. Leon S..________________________________________________________________________________

If people still run the cables in that area without pulleys, are wear surfaces or some form of guides fabricated? John,It seems that most folks use at least one pulley on the cable that goes up to the top of the bellcrank. However, there is absolutely NO reason that a pulley must be used there. I didn't use a pulley, and there is NO wear going onin that area, after well over 300 hrs operation. It simply rides on a piece ofhardwood, however, I did tighten up one of the turnbuckles up a couple of years ago, and maybe after a few more years I may have to make another slight adjustment. Copper tubing is not a very good fairlead, because it has poor abrasion characteristics, and there is also what is called Dissimilar Metal Corrosion. Pulley's add complexity to the design, as well as the risk of a cablejumping out, and jamming the control cable. The beauty of the Pietenpol is inthe simplicity of it's design. Changing even simple things like this adds an incredible amount of time, and thought that it takes you to build, and after allthat extra effort, you still haven't made an improvement. Stick to the plans, and just Git 'er done !!Chuck G.NX770CG________________________________________________________________________________

Subject: Re: Pietenpol-List: elevator cable routing under the rear seatI used pulleys also, but let me tell you about a problem that I am now in the process of correcting, that others have heard me complain about.My rudder cables pass under the seat and run thru the pulleys. After that they join with the tailwheel cable with nicropress fittings. I had set the rudder 10 degrees off to the right to counter the prop force. My plane has had a tendency to suddenly veer off to the left on the takeoff run shortly after the tail came up. This has lead to a couple of aboarted takeoffs, luckily with no damage. The conclusion I have reached is that the tension on the tail wheel releases as it leaves the ground changing the rudder position causing the plane to suddenly veer off if I'm not anticipating it. I am re rigging the cables, running seperate cables from the bar.Dick N. ----- Original Message -----
