I think..

Huh? Is Christmas over all ready??? Cheesy

Way too much coffee @ Bailey's Embarrassed

Anyhow, stab ribs on (discovered the laser cut ribs not quite correct) hardwood spars, then manufactured tips to suit. (no details on the plan) (but that's what plans are for). So now tips have to be sanded to match the leading edge profile, then sheet the thing....

I know the square root of squat about how the control surfaces on a Hurricane were hinged. Where did you get your documentation? Keep the pictures coming.

Mike - I'd started these from Vaillincourt's web site on making scale hinges,

then

took a good look at some photos I have and realized with the hurricane I'd be better off using G10 instead of ply. Concept is right, but hinge way too thick. (He was talking about thicker looks better). Well he's wrong in this instance...

Cool - p*** off Cheesy

Glen - did I ever tell you the story of how the Brits fixed the problem with the wings on the Comet breaking off? No? Fine.. Angry

The windows fixed the fuse problem. Smiley

There also was a problem with the wing. One broke off on the test plane, and there were signs of a tear on the second (before they got the plane into service). Wall Bash

The imminent tear was in the same place as the break on the first one. Every engineer on the island got involved, because the Comet was to be the salvation of the British aerospace industry, AND the airline industry... no joy Angry

Finally a young guy suggested they go discuss the problem with " " (you can likely floogle his name), an old, gnarly, retired Dehavilland engineer of the Hart, Dart, Fury era. He thought for a while, then suggest they drill a series of tiny holes (.001 comes to mind) right along the line where the wings broke and/or were stressing. Top and bottom. Right through the skin. It worked!!!! And the industry was saved. Gnarly one was Knighted. Raa Raa

plans show stab as sheeted @ 3/32, but original is canvas, along with elevators and fin/rudder. (Confirmed by guys at BBMF)

So, guess I'll leave it open with Leading edge and capstrips, same as fin and rudder will be

SO, now I'm editing again:

And after hours or heart rending pondering and studying, Really Im Reading

I decided to make the hinges from 1/8 ply. I was thinking G10 for strength, but remembered each side is going to have 4 large Robart hinges, PLUS the two large bearings at the center around the elevator joiner. I "think" it's strong enough. If 1/8 looks too thin I can double up to 1/4 easily.

A major deciding factor is that a 12x12 sheet of 1/8 G10 is $33.00 plus shipping/taxes/etc. Undecided

So, modified hinge idea, rotated "them there thing 90 deg" per the Cool comment, and in.

The hinge on the Robarts will be spaced from the trailing edge the same amount. Hopefully, once the elevator leading edge is built around this stuff all will pivot scalely..(important aeronautic term) . Robart has confirmed their points can be offset, and if I'm uncomfortable with their strength I can set them in a 7/32 brass tube from trailing edge to pivot.... Thinking

Well, back part of leading edge notched for ply hinge and drilled for robarts....then a secondary leading edge to secure the nyrod...then stuff and more stuff;

The center of the leading edge will be cut out and replaced with an aluminum rod (instead of the 25 gms of 3/16 piano wire joiner. Add a few ribs and the ply trailing edge, some capstrips, build up the leading edge and round it.....and Frank's my Uncle..

At least on the tail plane there are three large hinges, so just have to make them, not mix with the Robarts...

Each side has 2 outer ribs that poke forward and make the counterbalances. Gonna be tough to get them straight - can't use my 1-2-3's
