I used plain hardware store silicon rubber that I pumped into the improvised Teflon mould. It would have taken months for the silicone to set all the way through, but I did not have the patience and opened the mould after two weeks. As a result the underside is a bit rough, but the top side squares are smooth and well formed. I haven't used it yet, as the lenses are still at the rough grinding stage.
What?! NOOOOO! The ASI has been a bit of a distraction

Fully finished as in onto polishing or done?

Thats a cool idea to make laps! I assume you use pitch/acculap?

Ive still got time to catch up...
