Great overview Mitch… you are one of the Piping leads that I have always admired… and your communication skills were examplary… all the best to you. Sincerely, Ugo Matulić
Great in theory until you start working with more then one manufacture of pipe and fittings. All manufactures have some variance in their product. Like 90 degree fittings that are not a true 90. How about if your working on 12" on up most of the time but you want to do 60" one day or any other larger bore pipe? That system you have is fine for the small stuff but it's not really suited to real world applications.
I'm a retired UA 342 Welder....We can't buy or bring any tools on the job....I've had no problem fitting this kind of Pipe with just a few V blocks and some Flange Pins or a Vise and Jack Stands.....I sure this Contraption works fine but I wouldn't buy one.
Corsica and Sardinia... Your mission is to manage the small island of Sardinia, to the west of Rome... One of the outlying villages has not been tamed so RULE-WITH-CAUTION
