casting under pressure

samedi 5 avril 2014

well its starting to cool down here in the southern states and i think i will have to start casting under pressure



last weekend i did one small batch in the pressure pot which was sitting on a table in the sunshine, it was about 22 degrees, the blanks came out spectacular after about 5 hours



one night through the week i decided to whack a couple more in because i was home early, took them out after 5 hours and they had set but not fantastically, it was much cooler and no sunshine to warm the pot



i am pretty sure that air under pressure gets very cold so i think if i am going to cast under pressure for the next few months i am going to have to come up with a way to heat my pressure pot



i am thinking of getting an electric blanket which i can wrap around the pot, they usually have a couple of heat settings to pick from, trial and error should find the correct setting



has anyone tried this or had/have any other ideas i would greatly appreciate your thoughts and input



thanks



MIK
