Hi Pete,
Somehow, I don't think your supplier is selling you Polycarbonate. I have used and machined Lexan for many, many years, including cutting 19" diameter discs 8mm thick on a metalworking lathe, without any problems.
Yes, Some suppliers just don't want small order customers or they want to sell you a whole sheet, far more than you need for one project. Lexan is expensive if you have to buy a whole sheet but there are sellers on eBay who supply cut sizes. This seller supplies 400 x 400mm Polycarbonate sheets for £20 in 6mm thick and £33 in 10mm thick. I think it is a reasonable price for a one off machine.
