West Wings Skylark build thread
johnfireball:
Hi David,
I may be wrong but I would think the ply wing joiner should slot into a box section built into the wing. Did you neglect to sheet over the top and bottom of the intended box? Did you cut the dowels? They should be single pieces across the fuselage.
John.
Happy Days:
I think John is right David. Wing joiners don't usually come directly into contact with ribs. I think there should be a 'flat sided slot', or 'socket' for the joiner to slide into.
Here's a picture from the plans of one of my old models. (this is from a Spirit Elite) it shows the “socket” that links the first few ribs of a wing half (so spreading the load) and allows the joiner to side into.
Go back to your plans and see if there isn't something similar shown.
(You're not the first person to hit problems with you first build. We've all been to the place where you try fitting the model together and suddenly felt a rather hollow feeling in the pit of our stomachs :oops: )
billscottni:
If it was designed as a one piece wing, it may be that there is no box as the brace would be glued to the spars.
angry_muppet:
It was designed as a split wing; the first three wing ribs had balsa sheeting applied from LE to TE. The bottom sheet had to be cut flush with the cutout in the rib to insert the joiner.
The joiner can be inserted fine, it's just that it doesn't reach far enough to be supported by the third rib (leftmost W1 in the pic below). I'll happily live with a 1 piece wing if it makes it easier to fit, strengthen and work with!
rogallo:
my twopence worth is that the plan says dihedral brace not wing joiner, i.e. one pience wing.
