review the safety data sheets for each of your molding and casting materials,
then make and compare test casts with each of them individual assignment:
design a 3D mold around the stock and tooling that you'll be using,
mill it, and use it to cast parts
testing casting materials & molds
Tina and i were looking forward to experimenting with materials we had yet to use. SmoothOn Epoxy 202 was a fun place to start. we were so dern excited, that we forgot to read the saftey guides. notably, "Crystal Clear™ 202 is intended for casting in thin sections. Developed for casting thicknesses of no more than ½" was a guide we missed. regardless, our pieces came out a-ok.
time to begin machining! this week I wanted to capture fall (this is my first fall and it is simply magleafique). since i'm running out of pages to store them in my journal, it's time to lock one of these leaves in an O2-less environment as a leafsake.
