Bonding aluminium is a black art.
Gary Morgan has already pretty well built an aluminium KR. He now sells
them here in Au.

Thanks Adam. My concern with fibreglass is not the strength of the
resulting structure but my ability to achieve a high quality finish in a
reasonable timeframe and with a reasonable amount of effort using
fibreglass as opposed to alternative materials. I'm confident I can
achieve a good finish w
The strength of the 100% bond between the glass and the spar may not be
required, although I'm certainly not qualified to determine how much less
(if any) strength would be sufficient.

could be done with a foam core or with built-up or plywood ribs. Many
other planes use plywood skins on ribs. Not sure if any use plywood on
foam or not. I would think that ribs would probably be better.

Tony please allow me to put your mind at ease.
I went through A&P school and in that class we had a composite section.
We all built individual composition wing sections. 12"x18" ( no vacuum
bagging ).
I can assure you that ( like every school) there were a few less than
desirable students.

wack/bump, urethane can compress (dent) more readily and perhaps cause skin
delamination. Dinveycell can also be post cured at higher temps.

Glenn, Wicks and Aircraft Spruce usually carry these foams. The company that
makes or distributes it used to be in Grand Prairie, Texas. The original

Glenn, I am with Mark L, lots of time and weight. Sounds like you need to find
some honeycomb cores for your wings if you want to go to this much trouble. The
honeycomb would accomplish both things for you. The best preference for you
