    --> Europa-List message posted by: "Jim Butcher" <europa@triton.net> Fred, In response to your question Does the use of tapered pins assume future adjustment, or will the tapered pins "self adjust" in the event of future wear? Taper pins do not self adjust, but may be easily adjusted as needed. The main advantage is that the initial installation will not have the play inherent in the current design.

Richard back to blighty after flying a Cardinal (C177B - wings in the "wrong place") but itching to get back into G-OWWW.

    Subject: Re: Tailplane Torque Tube
    Has anyone looked at the possibility of putting a new set of holes at 90 degrees to the original set, in order to allow the original bits to be re-used with parallel pins in Jim and Heather's situation? One small but important thing I learned when I retrofitted mod 62 is that grease is much better than oil as a lubricant when you fit the pins into into what ought to be a slight undersize hole. I did several trial assemblies on the bench by way of a rehearsal as I didn't want to discover a problem half way through fitting for real. I found that the grease prevented the pins from seizing/picking up/ scuffing as you tap then into place, but ordinary oil allowed then to seize up before they were fully in place. Funny stuff, stainless steel. By the way, I have a set of slight undersize reamers which I bought for this and any member is welcome to borrow them. 80 flying hours later there is still not the slightest sign of any play at all. I do my best to protect the tail plane from unusual forces, eg banging from stop to stop if left pointing downwind in the fuel queue. Willie Harrison G-BZNY - now got the ratio of flying to fettling time up to 10:1 and rising...

    =9CThe tapered pins would be installed vertically since there is not much material left on TP9 (the center bracket) from the installation of 3/8", Mod 62 pins. =9D Jim, Tapered pins are probably a good solution but installing them vertically is an absolute no-go as this would significantly reduce the ability of the ta il plane to handle vertical loads.

    --> Europa-List message posted by: "thomas@scherer.com" <thomas@scherer.com> Just my 1 cent on the torque tube issue - whenever I drilled my tube - sure enough I di not yet have a drill-press - and ended up with too big holes. Found rescue in tapered pins and have been flying 9 years now without any issue or the need to re-tighten them.
