    this is what i been experamenting with to make cheep castings for my transformer stuff . i figuered i show kinda what 1 of them looks like and tell how i did it. i used the play-dough as a mold flatning it as level as i could and pressing the part right to the original mold line and did the 1st half let it harden did a small clean up then did the 2nd half but put the 1st part on top right after i filled it with epoxi and was wet and the 2nd part fused to the 1st part that way . clened it up some and used a paint pen on it could be better going to clean it up better and paint it agen black . tell me what you all think . thie has been kinda experimental at this stage
    the cost total
    play-dough 0.50
    the epoxy about $2.97
    total $3.47

    Play-DoH? Wow, that's an impressively cheap solution. I like it!
    There's an actual putty you can use that has a waxy quality that acts like a mold release. It's usually a one-and-done process since the mold bends when you remove the final part, but it's still cheaper than actual mold castings.

    My understanding is what ever you want; epoxy, resin, etc......it’s what make this stuff amazing for casting. eBay and Amazon sells it...like $8. And best part, you can reuse, reuse, and resuse. Not a bad investment, so you get your money’s worth. Check out some YouTube video, interesting stuff.

    this will be a 3 part because have to wait for it to compleatly cure hard part 1 of 3

    1st
    find the orignal molding line
    thumbnail (4).2.jpg

    2nd keep folding and rolling out your play-dough till you have it flat and clean

    thumbnail (6).jpg

    3rd press the item right to the orignal molding line thumbnail.jpg
    4th carfully pull item out and try not to mess up your imprint
    thumbnail (1).jpg
    5th put mix up your epoxy and drizzle it in and dont put to much in just enoff to scrape it flat with a straght edge of some sort thumbnail (2).jpg

    6th scrape excess off carfully thumbnail (3).jpg
    7th let it harden for an hour it will still be soft and bendable so be carfull wait like another hr clean with tooth brush and water . clip the excess of the edges thumbnail (5).jpg

    staytuned for tomaro the 2nd part

    I have used a technique similar to this in the past. If you want the mold that you made from Play-Doh to be rigid and not soft anymore just put it on a piece of wax paper on a cookie sheet in the oven 325 degrees for 30 minutes.

    Well now I’ll find a place in Australia that sells the epoxy and I might give this a go myself. Reckon it’d work for heads?

    I'll stick with Oyumaru and Milliput myself. But that's not a bad method!

    I assume this involves somehow bonding two halves together, my primary concern would be the handle not being sized properly as a result.
