Oooh, I'd love to try a proper circle cutter instead of my very DIY method!jamiegramo wrote: ↑Sat Mar 27, 2021 5:34 am A good tip, thanks Ahmed. Some of the glass diaphragms I ordered from Germany got broken. So I will give it ago especially at the price.
I also have a small glass circle cutter I can try.
I found 4 x 0.2mm sheets at £1.49 ‘including’ postage. Here’s the link for anyone else in Britain, unless you found cheaper?

These happen to be the exact ones I've been playing with. Cheap and cheerful; if they all snap, no harm done!
All the best with it, let us know how you get on!
