So, after success casting single DZ door units I have now moved on to trying to reproduce whole wagon sides.
And here is a mould full of resin...
...and here is one of the castings removed and given a quick clean up.
I've cast 8 of them now and I think I'm reasonably satisfied with the way these have come out.
It's quite tricky to get the rear surface - the bit that is on the top as you pour the liquid resin into the mould - as smooth and flat as I'd like it to be.
I have tried the trick of passing the edge or a sheet of clear plastic along the top, but perhaps I've not yet got the knack fully.
There are a few pinprick air bubble holes here and there, but mostly they'll be easily sorted with filler or something like that.
The other issue has been with the wee dangly bits below the frame. Not all of them cast perfectly every time - which is not surprising given how small and thin they are - but as the WHR wagons are more than a little battered and have quite a few of them missing hopefully we'll be able to get around it.
It may be possible to graft on some of the good ones which have to be sliced off in place of a couple of the ropey ones. The question is whether the bond will be robust enough for life on the exhibition circuit??
