Aileron ribs have metal doublers bonded
You have to be carfeul to make the correct Left and Right hand units. .. so doublers are on one side or the other depending if it is a LEFT or a RIGHT aileron … also need to check if its an UPPER or a LOWER aileron so that the pick up points are in the right direction !
TLAC provide a picture page to ‘pre test’ you on which aileron rib is which.
I found each rib needed to be sanded so that it could get onto the aileron spar.. again .. not too much off to keep it as a stiff fit.
This work is not being carried out at the barn but in my garage roof at home so I can nip out and do the odd hour here and there and its warmer than the barn so better for curing glue and ultimately fibreglass.
