where can i buy moulds to make a retaining wall for a model railway.?

Question

It is for a oo gauge, and it will need to be a mould for plaster parris

Answer 1

Okay...OO Gauge is the British system that uses HO scale track (1:87) with 1:76.2 scale locos and cars.

You can BUY the retaining walls (timber, stone, or concrete) from Woodland Scenics (they're made from hydrocal, a light-weight plaster).

If you want to MAKE molds... Woodland Scenics also has the rubber/silicone material to make the molds.

I work in N-scale, and have made molds OF their products so I could have the endless retaining walls I needed at less expense.

GOOD LUCK.

Well, it's not specifically for trains but see if you can find something here that you can use:

Contact them to ask for measurements if you're not sure.

As to making moulds yourself; I wouldn't use silicone rubber but latex. It's a fair bit cheaper and for limited run plaster casting you don't need the quality of rubber that silicone delivers (for resin and pewter on the other hand ....).

Example procedure for making a wall:
- create an original. For instance making it with plasticene or plaster.
- coat the master with a thin(!) layer of vaseline.
- coat the master with a thin layer of latex. Check for airbubbles.
- just before the first layer is fully cured: apply second layer.
- continue applying layers until you have the right thickness (say half a milimeter).
- let cure
- remove the rubber mould
- go casting
