I am in the middle of making my curved focuser board. But found the ply
in my case 3mm a bit hard to form the curve I need. So I opted for veneer
it's been clamped for a couple of days now, since it has been pretty wet
up here I've decided to leave it like that for a few days more.

One thing I hadn't thought of that I see in the design of your mould is using
ply to line the mould. I have used 6 blocks cut from 5"x1" hardwood. although
the surface is fairly square it isn't perfect.
