I recently made a number of re-usable molds for casting my cactus pen blanks and thought I would share with those interested. I went downt o Wally World and bought one of those big, white, cutting boards that are about 1/2" thick. The one I bought is made from HDPE and is pretty slick. The nice thing is that so far, nothing sticks to it, including Alumilite, CA, and epoxy but I am not sure about PR but would guess it would not stick either.
Ayway, I cut it on my tablesaw to make a square mold with square sides exactly the size I need. I then screwed the pieces together so that I could easily take it apart to remove the stubborn casting is I needed to. It works great and cuts down on the amount of wasted resin.
