Today i watched the Weihrauch Factory visit on you tube https://www.youtube.com/watch?v=VgCQf16QSjk

and very interestingit was too, what surprised me was how hands on it was, i thought there would have been more robots about the place, craftsmen were involved in almost every part of the manufacture. Something else that surprised me was the manual straightening of barrels using a hand operated press and checking by eye, i saw a similar thing when i watched Terry's video of his visit to the FX factory, seems for some things the rack of eye twist of gob is still the best method, not a laser to be seen.
