Nice work Bob!! What did you learn about the process?
One thing I just noticed on the blue and gold blanks. They are both from the same batch i mixed up and poured at the same time. Right now, the square one is solid as a rock. The round one is rubbery. I can actually bend it some. How strange is that? Is there a big difference in curing time between pouring into a square mold and a pvc tube?
