To get a good mold line-up - do this, assume we are making a pawn mold for
this example.
1) Have 2 slabs of soft Sculpy ready (for 2 mold halves).
2) Use some type of post (such as 4 nails) to act as line-up pins
(Push these through bottom of mold slab) one at each corner
3) Add talcum powder to lower mold to minimize piece sticking.
4) Push pawn half-way into lower mold
5) put wax-paper around non-piece area of mold
6) add talcum powder to top of piece
7) press top slab down, then remove (you may need to practice with
wax-paper and talcum powder)to prevent halves from sticking
8) Remove pawn and wax-paper. Leave the guide posts(nails) in place
9) bake mold halfs (apart) per sculpy instructions
the nails and molds will be hot, so allow sufficient cool down.
10) Later: when you use the molds, apply talcum powder (light dusting) to
both mold halves; then add the soft sculpy. The alignment nails should
give you a good alignment.
11) when you remove the pawn, trim away flash and smooth out the
mold-lines so they cannot be seen.
12) After all pawns are made-- heat them per instructions.
Note: for large items I put aluminum foil at the center of the piece to a)
minimize sculpy use and b) allow a better hardening
In regard to photos - I have not taken any. Also note that I have mostly
made characters from sculpy, also a dog, elf, strange guys, pumpkins, a
cow, ghost.... I do have a box with a partial Sculpy chess set
somewhere... perhaps lost in the garage.
