Complete Figure Mold/Cast - All Parts (Shoulder joints struggle)

Thanks for the response! Yeah, I figured I should probably hold off for now. The only thing I've been able to find on the purchasing joints is on Amazon (search "Premium Parts Collection - Ball Shape Joint" - but I don't really even know how big they are (3.75, 6, etc...). It appears to be multiple sizes and can be pricey. However, if these worked, I may be able to find a way to cast them with enough luck. If you happen to come across any ideas, I'm open to suggestions. In the meantime, I'll keep my eyes open. Thanks for the reply!

Hi Trust. As someone who's been experimenting with this idea for 6in figures, I can tell you the major problem you're going to have is casting the joints.

If you're planning to cast the joints in a casting resin, two problems arise: brittleness and softness. While casting is great for heads and body parts, if the part being cast is too small, the resin has great difficulty hardening properly, and often remains flexible and tears easily. Even if the joint hardens, the cast of such a small part will be extremely brittle, and will break off fairly easily with enough force.

The best, but most expensive solution is to buy joints as you mentioned earlier. Another route I'm currently exploring is finding a specialty casting resin that is durable, but slightly flexible, such as the plastic on an existing figure. That said, I have yet to find one that I'm confident in, as these specialty resins tend to be somewhat pricey.

Hopefully this saves you a lot of time and effort, and good luck with your custom!
