Is Your Pot Not Hot?

Last summer during casting sessions with a Lee 10 lb pot, I had the feeling the pot was not performing up to snuff. It would get up to temp. (800 deg) but it seemed to take longer than normal. This spring I ordered a new coil, and the picture shows what I found when the pot was disassembled.  The pot is around 20 years old and has served me well, so no complaints.  Lee stands behind their products and if parts are purchased, they are reasonably  priced.

While it is apart you might want to insulate the space above the coil with fiberglass. I did it and the pot ran a little better.

I have already put the pot back together, but i do put fiberglass insulation on the bottom. I'm going to run it as is for the summer and try to get an idea what the temp of outer shell reaches. Then put in insulation and see if I can detect a difference.  Would be a good to have one of those remote reading thermometers.  Also would be a good place for asbestos insulation if that were still available. Thanks for the tip.

Try doing a web search for "fire wool", or "ceramic wool". That's probably what you're looking for to insulate pots.
