It's nice to see another movie prop person on the board.
I'd brake your buckle down into 2 pieces. Basically the main buckle with the inner area dished out with a flat bottom/recess for the inner dial & alignment hole in the middle for the dial, and then the middle inner dial & drill it on the back for an alignment peg. Doing it that way should let you rough out and finish pass both pieces quickly and you'd have less areas on the silicone mold that would be thin/pointy down in the middle area that would break off when casting as the mold ages since you can cast it in 2 pieces. |
