Hey Kurt,when you ran your line back and over the rear spar near the rib, did you drill a hole in the #1 rib to run the line thru before going into the cabin?Not drilling holes in the spar tube sounds good to me. Thanks---Leon Morris/Classic4(1994)/50%/Flower Mound,TX

Hi Leon,



Yes, I recommend tying the tubes to the spar with

stitching line.  I used nylon ties, but understand

that they deteriorate faster than the stitching line. 

Tie the tubes well well so they don't wiggle loose

over the years and start flopping in your wing.



Then I drilled a hole in the web of #1 rib close

behind the spar, but out of the epoxy.  You need to

look closely at the wing when folded to pick a good

spot for it to line up with your entry point to the

fuselage.  Then you also need to add a small plywood

support to the inside of that last rib flush with the

cap strip edges, or the fabric covering the rib will

be pulled and torn by the line as you fold and spread.

 You need to leave some slack not tied off so that the

line can move in and out of the wing a few inches as

you fold and spread, since the tube is not on the

hinge line.



I wonder now if you could mount the pitot/static tubes

out near the tip and run the tubes in thru the end of

the spar instead of drilling?  It would still be a

good idea to run them thru a protective thin walled

tubing along with your wires to your lights so noting

wears on the spar rivets, etc.



Just an alternate idea....
