Is there a commercial product that consists of a 2 or 3 mil thick stainless steel blade that heats to about 300C and can be used to slice into junk like epoxy for example?
If not, what's the correct and modern and cheap way to drive about 10A DC at something like 200 or 300mV, and regulate the temperature of the load? Assuming there's no thermistor or other sensor. (I imagine finding such a sensor that'll fit in the gap will be tough).
I need to cut "blind", so instead of a heated ribbon, I will use an elongated U and drive the ends of the U. It won't be big, about 0.5 inch long. So about 1 inch total length, and maybe 100 mils wide on each leg of the U.
I didn't find electrical data for shims because I suppose that isn't what shim stock is typically used for.
The thinnest razor saw I can find is 8 mils thick. So that's why I'm leaning towards something weird like this idea.
I'll pick up some SS shim tomorrow, it's cheap by the inch.
