Ken, my brain is filled with the stuff I read here from people like you and other great sources, I doubt I have anything as original or as creative as the work you do to offer the world.
If anybody wants to see it, here is a small video we shot of our process awhile back. In this clip we are using a smaller furnace (the bigger one is right behind it visible in the corner) and we are using only a 5 gallon bucket for a quench tank with no airline which is a setup we used to use frequently for small parts with good results. You can also see our "high tech" toaster oven in the background that we use to draw the parts once their out of the quench. We have more sophisticated furnaces, but the toaster oven works and it is cheap. Anyway, here's the link.
