All,

  

 The following is posted on behalf of Fred Klein who  is having a few computer problems at the moment.

  

 Cheers

 Kingsley

		     All Mono Driver / Builders,



I've always marveled at the precision,    geometry, and ingenuity of the outrigger retraction / latching mechanism on my    monowheel...I recall the first time I heard that satisfying "THAAAWHACK" when    retracting the flap and outrigger as the nylon rod engaged the end of FL3 when    the wing was resting in its vertical rack. (the pix below shows my stbd    outrigger encased in Kingsley Hurst's wonderful fairing).



Alas...when    the wing was rotated horizontally and mated to the fuselage, the weight of the    outrigger was just enough to prevent full retraction and the nylon rod w/ the    outrigger wheel sagged about 3/4". I was disappointed with this, particularly    because whatever benefits to be derived from Kingsley's fairing depended upon    full retraction, or at least that is what I thought.



Upon inspection, I    concluded that the sag was due to an accumulation of the tolerances for fit of    the various components of the retracting mechanism, notwithstanding the high    precision of their manufacture. Ultimately it became clear that the problem    could be solved by a slight increase in the rotation of the outrigger w/    respect to the retraction of the flap.



See Fig. 17, p. 12, chap. 9M of    the build manual.



See also Fig. 24, Section 6, p. 16, chap.    9M.



I've accomplished this by putting an eccentric on the leading    radius of the spacer OR10. I've made NO alterations to the slot in OR5;    however, I have enlarged the 0.25" hole in the plastic washer adjacent in    order that the spacer bears fully on the AN960-10L washer. Following trial    mock-ups in aluminum, a local machinist has made me a new pair of OR10 spacers    from stainless steel; the new spacers still fit in the 0.25" slot in OR5...see    photo below alongside standard OR10 spacer.



(The black marking on the    side of the new spacer is just marker ink to differentiate it from other trial    spacers.)



The results could not be better...the sag is totally    eliminated and there is no perceptible difference in the flap retraction /    deployment lever movement or amount of force necessary.



My machinist    has saved the program for his CNC cutter and is willing to make up more in    batches of 10 or more...contact me off list if you'd like a    set.



Fred

great fairings! I have the europa supplied ones which must be poor due to the open back. Does anyone supply these?

Hi Kingsley and Fred,

I would like to try a couple of your eccentric OR10s.  But you are in Australia aren't you?  Might be hard to get those to Kenya, but I have a UK intermediate address.

Hey guys, just come across this thread and I'm with Richard, I wouldn't mind a set of those. Thanks Frank

Richard...should be able to post them just about anywhere in a small padded envelope. I'll put you on the list and will advise cost and timing of a little production run.

Hi Fred,

How much are you asking for the eccentric OR10s?

Martin,

I've been assured, now that there's a program stored in the CNC machine, that the costs for additional pieces will be nominal.



I've just now emailed the guy asking for confirmation of cost and minimal quantities for additional pieces...I'll let you know just as soon as I find out.

Fred

PS: BTW, I often go to your YouTube video when I need a bit of inspiration to complete my build.

I've had saggy outriggers for 13 years! Guess I need to get on your list! 

I can pick mine up:)

Thanks

Regards

Jerry

Thanks Fred,  I can pay you by Western Union, when you are ready.



I think for all of us fitting these to completed/ flying Europas, it will be essential to jack the plane up and do quite a few retractions to see that all is in order.

Richard,

Certainly a prudent suggestion. Though my bird has yet to fly, my workshop allows for full assembly and that's exactly what I did.

I would emphasize that my outrigger retraction/deployment mechanism was fitted exactly as per plans and I did NOT do any filing or nibbling to bolt holes or slots in OR 5 (or other components) in the original assembly or in any adventurous attempts to eliminate the sag of the outriggers.

Fred

PS: Here in the US we're in the midst of the Thanksgiving holiday...last nite I learned from my machinist's father that he's away for a few days...so I won't be getting cost confirmation and delivery time for a bit.
