Parashooter I probably have done a few by hand that way. Also made a holder for the cordless drill. I have used tempil markers and they are difficult to see when they actually run, for color blind me. I put a bunch of Tempil marks on some brass to anneal later and found out the material is very corrosive on brass. I never felt I could get the angle and temp of the flame consistent enough with the torch and again my eyes do no see the colors like others would.
I have accidentally picked up hot objects that have been in the oven and never been very good at judging the temperature as I let the drop. I thought that was what Butlersrangers meant. My fingers are not calibrated for 650 to 700 degrees. Once the guy on the lathe in front of me threw a hot chip over the machine, it was berylium copper and about that hot. Landed between my glasses and upper eyelid. As it was cooling off against my skin it was vibrating and buzzing, thought an angry wasp was in there. Could not take the glasses off fast enough and each curl of the chip burned the skin black.

Bote, I looked up several references to your system and all are doing 950 to 1000F. Do you know why so hot? References say 650F will actually anneal but it takes too much time and the extended time will allow heat to get to the rest of the case. So 700F is recommended to anneal quickly without the heat damaging the body of the case. I would expect a molten liquid to be as close to immediate on the transfer time as anything could be.
Also where did you get your supplies?
Thanks, Fred
