Yes he does. The same casting supply shop where we were already buying our silicon mould making and resin casting supplies. Unless something has changed, according to hirst arts that would be fine, except the taking over the world part because you aren't allowed to sell the moulds you make or the stuff you make with them. Casting up a ton of 6 inch squares would be trivial though. Much bigger and the silicon cost would be getting silly. I've done quite a few open moulds now so I actually know what I'm doing and everything.

Does said place of employment have a website so we can peruse their wears?

I'd be willing to contribute to any mold made as I would love a dozen or two 6" X 6" cobblestone squares.

Cheers,

6x6 Mk-1

2 flat sides and 2 wobbly sides, so they can be joined to make a 12x12

Parts moulded

Glued together upside down (photographed) to ensure the visible surface is flat

Joins on top surface filled

So, should I roll something on to the bottom to add depth and even out my poor moulding? I could use Milliput or some air-dry clay?

Top

What about gluing to a bit of wood? Any gaps around the edges you could then fill in with the milliput.

Also any gaps between the pieces would need filling with milliput (?)

Ray/Mat are probably better placed to comment,

Just like that will work fine

Good work!

I've milliputted the gaps
