Cheers - I won't have to rely on the FB suggested videos with nauseating music now.
BTW I assume you've seen the other end of the hydroforming spectrum where Colin Furze makes a pulse-jet engine with a pressure washer.

Not Furze in particular, but generally there are some highly ingenious people in sheds out there.
