 Posted: Mon Sep 10, 2012 12:58 pm Post subject: Ply wing skin crack fix.... |
 |
|
I've been reading through a big pile of Pulsar Newsletters I recently acquired and among all the interesting stuff in them I found reference to a fix for cracks that some guys found developing in the Birch lower wing skins at the Main Spar join.
Does anyone have details of what the fix was and was the cracking limited to non glassed ply wing skins or have they occurred on glassed and non glassed wood skinned wings?
Cheers,
Matt.

I have glass wings and Aero Designs had instructions to
add glass on the underside of the wings.
They said to add 18 ounce of glass, I thing 16 to 18
inches out from the base of the wing.
You could use 2 9oz layups or 6 layups of 3 oz glass.
This was not to fix a crack but to keep one from starting.
I used 3 oz glass so I cousd feather it out better.

Thanks Clarke,
I finished reading through all the newsletters last night and came across a more elaborate article and drawing that Aero Designs published. Guess I should have finished the mountain of reading first!!
Do you have 900lb or 870lb spars?
