A quickie that might be of use:

I'm getting drawn more and more into 1:33 scale WWI aircraft modelling. With most of the freebie models available, the thickness of the card stock is critical in getting an accurate and clean build, especially with laminated formers.

Not having a micrometer, and with the card stock I'm buying not having any accurate specs available, I was left puzzling how to measure the thickness. "Yeah, it looks about 1mm. But with my eyesight and just a ruler it's impossible to measure." wall1

Simple. Just cut 10 pieces of the card and clamp them together. Then measure the thickness of the stack and divide by 10. For thinner card, cut 20, 30, 40, etc and divide by 20, 30, 40, etc. Whatever number gives you a stack that you can reasonably measure with a ruler.

My 1 mm card turned out to be 0.86 mm. Laminating it with my 0.16 mm printed card gives me 1.02 mm.

When cutting slots for formers (wing ribs, fuselage formers, etc) use a scrap piece on edge as a guide for the cuts rather then just following the printed lines. This gives a nice snug fit. If it's a repetetive set of slots (eg. wing ribs) make the first cut always on the same side of the slot, then make the second using the scrap piece as a guide. This ensures accurate alignment of the pieces when you assemble them.

Thanks to all those who take the trouble to post to this site. I've learnt heaps since I became a member.

I've bought a cheap set of plastic callipers (made by ADW) at something like \$3 in a hardware store (Praktiker I think). They're graded to 0.05 mm, and are also graded in inches (but I would certainly measure several sheets as it will reduce the measuring errors).
