newbie question: drill for probe?

[Dead Dog Jack]

What is a "drill for probe?" I see it requested when some order moulds in the group buys. TIA.

It's a request to drill one of the mould blocks to accept a customer-provided thermocouple. Used to determine exact mould block temperature.

SweedeNelson is offering the option to be used with the digital casting thermometer (http://castboolits.gunloads.com/showthread.php?t=100997) that he sells.
