Thanks everyone, Good to see you dropping by Leon, pitty not to see your cold box in action. The copper plate is .7mm thick from a hobby store. Had some 0.5mm aluminum just incase it was too thick.
Hooked up the temp controller for a quick test and the cold finger easily gets down to -4c with the ambient temp sitting around 22.5c. The controller can be set for high and low temp but can`t set it to less than 2c between the two. Will go to -20c at max. I think I would run into probs trying for that..
A modest 0c sounds pretty good to start....
