I dont think Goeff ever did a construction article on the LA-1. The original LA-1 was very different and a lot less attractive than the later ones. I think Dave Scully worked with Geoff a little on the next version, (Dave was master of airplane styling and glass work) which was still wood but had a glass top. It looked a lot like the final all glass version. I had one wood/glass top one that Geoff build for me and I think 4 glass after that ones. I sold 3 of them and wonder if they are around anywhere. Two went to Mexico and I cant remember who bought the third.
I borrowed the wood fuse/glass top construction method from the first LA-1 I had and used the method on the Desire 60.
