[PSUBS-MAILIST] Bike sub program

[Alan James via Personal_Submersibles]

James,just my kind of project:)What about borrowing a divers BCD & a pony bottle or small tank, if you only have a couple of days.Strap the BCD to the top tube of the frame, nearer the seat, & clamp the bottle to the seat post (verticalpart of frame under seat) or wherever gives you good balance. As long as you add some weight downlow & keep some air in the BCD, it should stay upright.Maybe ask Emile, they have lots of bikes in the canals in Amsterdam. I think they said one goes in every day.Alan

Hi all, I have been asked to make a "sub" for a TV program about HMS Astute and subs in general.  For some reason they want to make a bike go underwater to demonstrate a sub diving and surfacing. Anyway, im going to have about 2 days to make this thing and get it working so its got to be simple. Nothing is confirmed yet, I don't even know if its going ahead, but I gave the a rough idea of what I thought could be done in the limited time.  This is my first idea.  I wondered if people could have a look and see what they think?   Any suggestions, top tips, completely other ideas are most welcome. Many thanksJames
