A ply monocoque is exactly what I'm thinking for an A7 Nippy, though that's probably been relegated to number 3 build. I've realised that a car I'd dismissed previously is actually a feasible proposition so that's been slotted in as number 2.   

I’ve checked out Bloody Mary. I wouldn’t say that was a true monocoque, it is still using longitudinal chassis rails, albeit made of wood.
I’m still keen!  What glue would we use? Something exotic, or ordinary woodworking glue?
I’m going to knock up an Autocad drawing!

What is the overall dia. of a 17 inch wheel...about 22 ?

Well Issigonis Lightweight special was plywood, essentially exactly as was suggested in the first post Every early GN was wood chassis (as is Kim, hanging from the ceiling here too) as well as many early cars.
I don't see anywhere in any of the guidelines that you should seek to replicate an original chassis
Slack Alice, I didn't note anywhere in your starter post that you mentioned monocogue. However, my Austin 7 build was, Derek's Bentley is, my/Wes' Darracq is..
Glue I use ALWAYS West epoxy, I've probably used hundreds of litres and am very happy with it, so why change. I did build a few small boats with resorcinol glue and had failures. I was once persuaded on another cyclekart forum to use Gorilla Glue, another total fail when subjected to the test process I use.
Wheel diameter around 22" depending on the choice of tyre.
Photo of Lightweight popped up today!
