A bit delayed (see hournal), but a couple of R&D pics from March.
Here is my new, larger, vacuum-forming table for putting textured silicone over even larger items. The smaller original can be seen behind it.

This new one's 200mm in diameter on the bed, so I can do several textured masters at ones. It's already giving some very nice results.
You can also see the quick-connect air-fitting to the left, which lets me swap the tables easily. Of course it's supposed to be a pressure line, so it's on backward.
