You done good Bob, looks great for the first. You'll get the hang of it.
I built my molds out of 1/2'' UHMW,(i can get enough scrap from work) if you can get your hands on some, works great, blanks will fall out with alittle tap on the bench. But DON'T sand the inside the mold DAMHIKT. Some guys use the thick white cutting boards, some have made the molds out of clear caulking. We also have some GREAT vendors on here that sell molds.
Trial and error little buddy, you'll get it.
1/2" and 3/4" PVC pipe works great for forms also.
The PR pulls away from the sides as it cures and should slide out fairly easily. A bit of persuasion with a dowel and hammer helps too.:biggrin:
I just tape off the bottom end with blue painters tape and the mold is ready to go. When it gets too funky from repeated castings, throw it away and cut a new mold.
Nice first pour, BTW.
I like it Bob!! But...what did you learn in the process?
