Thanks Mr. Scott, now I understand better why you harden one blade at a time despite the fact that your chamber is large enough to do five blades at once.
In my understanding your furnace has a large reserve in the installed heating power, 4 kW I guess. What time do you need to heat the furnace to 1650°F?
I have visited your links to Kanthal elements and found many inspiring things there. My problem is that I live in Europe and not everybody is ready to ship over the pond. Shipping costs and custom fees also often lower the profitability.
Many Kanthal heating coils are offered here for prices lower than the price of good quality Kanthal A1 wire necessary to coil them. I am afraid they are not made of quality wire.
Even more I have derived a formula for Kanthal wire diameter, which will support the requested Watts and respect the typical wire loading (max. 18 Watts/sq inch), and I would like to test it.
