@pagan8th – no criticism of you here! It’s a great video, it’s a really interesting project. I like the idea (of mixing tech and tabletop gaming). I just think Jazza is (not for the first time) a little bit disingenuous in how he presented the idea – which parts were down to his innovation and which were “borrowed” from elsewhere.

In other news, my worst fears materialised today with my homebrew Demon Ship tiles: they started to warp.

You can see that they’re really starting to curl up!
And then I remembered a trick Mel the Terrain Tutor gave me, many many years ago (when I went to visit him when he first moved into his studio in the Spode Works) – if your mdf warps because you glued stuff to it, put some glue on the other side!

So I did.

and made sure I smeared it around to cover the entire area

then stuck some black HIPs (polystyrene sheet) on the bottom and clamped it inbetween two sheets of Dibond (aluminium reinforced acrylic sheets). This helped ensure that the whole tile was squashed completely flat between the wood-working clamps.

(my clamps don’t have particularly deep throated openings, so I couldn’t clamp all the way around without cutting the Dibond sheets down – so just did the best I could with what I had!)

After leaving it overnight and checking, the result was very encouraging

A nice, flat tile, that sits perfectly on the tabletop with no rocking or wobbling.
I guess time will tell if it starts to curl back the other way – it did take about three days for it to become noticeable after I glued the resin tiles to the top, the first time. But the theory is that the original shrinkage that caused it to curl one way (as the pva glue dried on the top) should now be counter-acted by the pva glue on the bottom (forcing it to try to “curl” in the opposite direction).

I’ve seen this idea work for Mel in the past – fingers crossed it works here too!
