We got the cart all built today. The crucible isn’t much good if we can’t steer it around, and that is the the cart’s primary task. The secondary task is to provide a frame that will fill with high temperature insulation (refractory).
The third task is to provide a thermal heat break from the 2000F crucible. We selected stainless steel for that task and in addition, the stainless doesn’t make full contact with the steel it will be mounted to. So the stainless is about 1/4″ away and only make contact where it is bolted.
