Anybody use blue stuff to make molds? I’m wondering if it would work well to copy a lower torso (modern 4” scale). Seems like green stuff might be too stiff for the actual cast. Do you use millliput? If so I’m not familiar with that, any differences in how to use it as opposed to green stuff?

You can find reviews and tutorials for blue stuff if you search for oyumaru. I can save you some time though, cheap and easy won’t get you the results that I know you’re looking for. I’ve had a few friends try it and they don’t use it at all now. There’s too many issues and variables involved with using oyumaru to make it worth the effort, especially if you are trying to copy a highly detailed part. There is no way to get even pressure when using your hands to force the green stuff together in the oyumaru mold, which will result in loss of detail and distortion of the copy. Add in the time it will take you to clean up all the flash/extra material around the copy that you’ll need to remove, and it becomes work harder for less.

There is no cheap and easy way to copy parts and get quality results. If there was, everybody would have already been doing it years ago. Silicon molds and urethane resins using pressure casting is still the best method to copy parts. It’s a significantly bigger investment of time, money, and materials, but the results will also be significantly bigger too.

Thanks man!
