I have a piece of lead (2mm x 2mm x 2mm cube). What is the best method to make a hole (200 micron diameter) in it? I guess it is too soft to simply drill it, since I care about the smoothness of the walls. Can you recommend another way of doing it?
Very Interesting question, similar to my case. Could you check one of the spesial journal in .... (lets me check first....)
In a different thread (link below), I asked about a superconductivity measurement. I got a few very helpful answers, and it seems that setting up the Meissner experiment is the right solution for...
