which two metals/alloys are you using? and which one goes to top half?. very interesting to know how well the junction will hold under normal / extreme operation conditions (vibration and heat).
Aha, thermometer built in!
We are using some of the Brass and BRB alloys and top part is BRB. We are using state of the art welding technology to put these two parts together. Our testing will show if it is durable or not. It has been run already on testing stand, now is time for track.
