Tip of the Month: Silly Putty molds

Silly-Putty-molds
Our T.O.M. comes from our longtime friend Sam Lopez, and is a variation of the old "Copying Small Parts By Pressing Them Into Clay And Filling The Cavity With Resin" technique, although we're sure there's a shorter name for that process somewhere.  

Here's Sam's unique and imaginative take:

"I needed to copy a small part (a side mirror), but I didn’t want to make a rubber mold and go through all that hassle. Instead, I placed the part on a clean, flat surface (a piece of glass is a good choice), then I pressed a ball of Silly Putty over the part until the whole piece was covered.

"After removing the Silly Putty from the glass, I placed the Silly Putty (with the part still embedded in it) in the freezer and waited for the putty to harden. Silly Putty is originally greasy, so the part came out of the frozen mold without a problem, leaving a firm and undistorted mold.

"I then poured 5-minute epoxy into the mold, waited until the epoxy hardened, then waited a little longer for the putty to thaw and regain its flexibility. The result was a hard and perfectly formed part that easily came out of the now-flexible mold."
