Polyurethene Resin Casting

[GNRi1959]

I'm sure quite a few members have tried polyurethane resin casting to make models. If the original casting master was a highly detailed piece it would produce endless copies quite quickly as 'easily'? Are masters generally made from plasticard?

I would use plasticard as it is easy to work with.

Watch some youtube vid's to learn the do's & don'ts.

Try to keep it simple, not too thin or thick.

David Holman has built wagons for his Arigna Town & Clogher Valley layouts using resin castings produced with plasticard masters, page 10 of his workbench covers the Clohgher Valley vans.

Thanks for this, it is a most interesting topic. One i'll be reading about over the next few weeks.

I've a lot of admiration for folk with the skills, time and perseverance to make a success of resin moulding. Having watched a good number of informative youtube's on it, I think I'll stick to plastic card, 3D prints, and using good quality resin parts made by others who have the skills to do it accurately and neatly. David's excellent wagons in the link above are a good example of success with this medium.

Noel, my feeling is that if you have the patience to build a very detailed 'master', then the obvious development from here would be to cast it and replicate it as many times as required. I don't imagine it will be 'plain sailing' but I think building multiple individual wagons is very time consuming. I love working with plasticard but it would be nice to see what results I can get from casting.
