23rd September 2013 - Covering the right wing top surface

With the help of my neighbour Daryl I re-organised the garage to allow access all round the right wing which was placed on a couple of saw horses. I had previously called Jason at Stewart Systems to get advice on how to cover a fully sheeted wing and followed his approach. First a piece of the lightweight Ceconite was cut to size to fit the top surface of the wing.  Then a glue line (EkoBond thinned 10% with water) about 1" wide was painted around the edge of the wing. When still slightly tacky the cloth was laid over the wing and smoothed out as far as possible. More glue was then brushed over the glue line and, as always with the Stewart System, any excess was removed with paper towel to leave it matt looking. Once this was set the cloth was shrunk with the iron to remove any wrinkles and looseness.
Then it was a case of brushing (using a foam brush) more EkoBond, thinned 10% with water, over the entire surface of the wing and, as before, all excess glue was removed. I found that gluing about 2 sq ft at a time was about optimum to ensure that the excess glue could be removed easily.
Finally I made off the ends of the wing. and the trailing edge. The cloth will wrap round the leading edge and overlap the bottom cloth by 3". However no finishing tapes are required as the cloth will be completely bonded to the wood. According to Jason,  it should be possible to avoid the join being visible by using a small amount of primer on top of the EkoFill to level out the cloth edge. I used about 300g of glue to fix the cloth and as much of this is wiped off the approach looks like being lightweight. All together covering the first wing surface took about 3 hours - not too bad!
