I really like the tapping machine – excellent idea to have the flat face on teh 'wrong' side of the angle.
Slightly nervous that the 'Junior Engineer' article doesn't really explain the techniques (e.g. silver soldering) if aimed at beginners. Also, it omits explaining how to set the safety valve after you've made it…
