Hirst Arts Tutorial at Adepticon for 40k Terrain
During the first day of Adepticon, I attended a couple of great classes. The Hirst Arts terrain molds class by Rich Nelson (writer of Chicago Terrain Factory Blog) was great. This is an invaluable technique for both fantasy and 40k Warhammer Scenery.
There’s only so much you can do in two hours. However, Rich made great use of the time. He covered casting, construction, resin casting, free build casting, and mold making. We had plenty of time to cast four molds worth of material.
Highlights and points Rich shared:
- Plaster and materials typically used for model railroads is not sufficiently durable — use HydroStone or dental plaster or Ultra Cal 30.
- Spray wet water on your molds before pouring in the HydroStone (make by adding a bit of Jet Dry to a spray bottle of water).
- It takes 20-30 minutes for most molds to firm enough to dry to remove from the molds; you should let these dry hard for a couple of days before gluing (but this is a guideline — some people do it in less).
- Use wood glue or liquid nails to glue the pieces together. Another hint here is to assemble peices flat and then stand them up. You’ll end up with a much better result.
This is a really easy process. The Hirst molds are, in my opinion, quite expensive but they could last a very long time.
