I always fancied making a submarine, just to see if i had the technical ability to do it. Suprising how many problems there would be making a fully working one that could actually dive and re surface without leaking lol. I get the feeling if i made one it would dive no problem but resurfacing might be a problem, soon see how good your welding was
I quite fancy building one,even when i was young i always wanted to work in the shipyards,but living in kent there wasnt many around being 40 miles from the sea let alone a shipyard!
And unfortunately now ther are'nt many left anywhere,although my cousins husband works for Thales in france and has offered to try and find me work in the yards over there,but i dont have any real professional welding experience as such let alone shipwork etc,ive build plenty of trailers etc and spent 2 years at college studying c&g welding and fabrication but went off at a tangent into construction.
