I have been generously offered some of Jadboog's spring steel for a saw plate. I was planning to make a 14" tenon saw with 3 1/2 depth of cut, but I am worrying that that the steel may be too thin for a saw of this size, it is 0.5mm (see thread "Is this normal"). I notice LN do an even larger saw (16"x4") in this thickness (it's listed as 20 thou which is near as damn it 0,5mm) but that most of the other larger tenon saws are slightly thicker. My 12" Tyzak is 0.67mm. I kind of need a saw this size, but my main interest is having a go at making any saw, I could always buy a 14" saw on ebay and make myself a smaller saw.
Any opinions welcome

Don't know if it's suitable. I do know that all my tenon type saws are more towards 0.7 mm plate.
My smaller dovetail saws are either 0.5 or 0.6 mm's. My Veritas carcass is 0.5 mm, larger than a dovetail saw but nowhere near 3 1/2" depth of cut.
 
There seems to be a bit of a fashion for very thin sawblades lately. For something with a 4" depth of cut, vintage ones tend to be around the 0.028" (0.7mm) mark, give or take a bit. Thinner is fine for a cosseted workshop saw, but for anything likely to see a bit of rough handling, I'd be worried about a 0.020" 4" deep blade being prone to kinking and bending.

Just a thought - how about a 14" saw with about 2" - 2 1/2" depth of cut, filed crosscut? A bit like the 19th century carcase saw, but updated for modern use primarily trimming to length with a bench-hook. You very rarely need the full 3" or so depth of most saws used for that duty, and the extra couple of inches length would mean longer strokes (as the thespian said to the prelate) so fewer of them. The lesser blade depth would match the thinner blade nicely.
