content: Quote from: P90 on June 14, 2017, 12:58:12 amI should have quit that job because of poor working conditions! The crimp tool didn't take the AWG8 without adding a hammer, the soldering iron didn't like that cross section either, and where's my electronics side cutter???*cough* almost forgot that my boss is again me in this caseAt least I am happy that I have found a proper space for my hobby now
