Just getting around to reading some of my magazines and gazing at the gorgeousTiger Moth on the cover of the May issue of Sport Aviation, it dawned on me thatthe elevator cables on that beautiful airplane are rubbing on the leading edgeof the horizontal stabilizer, just like the Pietenpol.Who says Mr. Pietenpol made a mistake in the cable geometry?!!! ;o)Oscar ZunigaAir Camper NX41CC, with elevator cables proudly rubbing the LE of the HSSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________

I believe the routing of the Tiger Moth elevator cables is such that thecable would ALWAYS make contact with the top of the leading edge of thehorizontal stabilizer, not just when the cables are slack (as on thePietenpol), thus the need for a support for the cable.Here are a couple of links to photos that clearly show the cable supportmentioned by Graham. I'm sure if you look closely again at the photos in theSport Aviation article, you'll see them there, too.

Subject: Pietenpol-List: Johns Piet builders prayerI came up with this one today and I felt moved to share it with the Piet Builders. I think its fitting, or that during this weekend there was just toomuch saw dust in the air to think straight. I may engrave it on a plaque for myshop as it captures the essence of the build. Spent the weekend laying out the tail feathers and cutting edge material for leading and trailing edges, a lot of time and a lot of router yields a bunch of scrap lumber and loads of saw dust, shavings and chip to clean up. It sue felt good to get back to the important things in life like makin sawdust! God its great, God its good, Building my Piet from glue and wood By these hands, made my cheap tools dead I pray to God for good ones instead!

RE: Pietenpol-List: elevator cables: in good company And the DH-4 mailplane would also have rubbing cables except for two little tiny roller pulleys mounted on the leading edge. You could do that if you're REALLY concerned. Something else Dehaviland liked to do was install bracing cables from the horn back to the trailing edge. Clif I believe the routing of the Tiger Moth elevator cables is such that the cable would ALWAYS make contact with the top of the leading edge of the horizontal stabilizer, not just when the cables are slack (as on the Pietenpol), thus the need for a support for the cable.________________________________________________________________________________
