Today I spent 4 hrs making and fitting a 1/2" dia long frame stud to my 1930 built like a bridge Francis Barnett. The bike is nearly finished but I wasn't happy with the old stud, thought I could drive out the old by tapping in the new, wrong! It had to pass through 14 different items ( frames tubes, spacers, washers etc) non of which wanted to stay put and some under tension (so was I). So much for a quick job.
