Hi, I'm building a 2/5 gypsy caravan and need some advice on choosing a casting resin for a part which is taking on weight from a leaf spring, So I guess I need something which isn't too brittle?
The part can be seen on top of the axle.

Hello Matt, I have done the castings thank you, On a drunken night in I put my full body weight on the axle which is way more than needed with no problems at all. I could post my progress on here if anyone is interested with the finished carriage.
