Being one who records whilst they work and edits in the twilight hours. I know the difficulties and how much effort goes into making these videos. Material like this is undervalued. Education has changed so much with YouTube. Society are gaining the equivalent of a YouTube plumbing degree. It's good when it's used for something positive like making individuals better engineers. Onsite experience is vital as well as real qualifications. Yet this media stream and experience passed on is helping nations strive to better engineering standards. It would have been a game changer if I had some of these videos when I initially qualified as a plumber 13 years ago. There was hardly anything like this to watch. It's great that the information is there for those that are thirsty to grow in their knowledge of the trade.
2:38 my bike handlebar end weights are fixed in a similar manner. Tightening the screw will cause the rubber, placed inside the handlebar, to expand and grip the handle bar.
Number 8 at the 10:20 mark, the tight-fit tube cutter by NERRAD TOOLS, is worth the price of admission. Your AMAZON link shows 4 sizes priced from $41 to $128.
Amazing new tools in the market. Although they seem to make the plumbers job way easy, one has to have the knowledge and the skills of a real professional.
Impressive tools , nevertheless.
