I am updating my sourcing for semi-finished spherical blanks, and I find lots of BC choices in the mid to high indexes... which is great.
But I am only finding the 2, 4, 6, 8, 10 base for CR-39 and Poly. I know there is not much money in either of those products, but does anyone know a supplier for the odd number base curves 3, 5, 7, and 9 in spherical CR-39 and Poly?
Thanks, pm if you don't feel comfortable posting.
