Paddy,
I use the thin plywood (1/8 inch up to 3/16 ) that are used for flying models on control and engine mounts etc. Laminations can be as many as 6 and I also laminate two thicknesses to get more depending on the depth of the prop. I also use assorted veneers which are 1/16 or less thick and glue/clamp them in layers for the stock. I bought a Veneer sample pack (Lee Valley Tools) which has several dozen colors in it; sheets are 12X6 inches and I've probably got a lifetime supply there.
Chris,
I'm gone for a 4 day weekend visit to my Daughters, I'll put together a brief and basic how to thread next week on return.
