not that big when you see the battery 2x6voltx4amp jell type takes the tube down in the water for a nice draft

Mine has a 24" long, 80mm diameter cylinder, with a water pump ballast system.

Hi Willte,
Interesting photos. I think I can see why you are looking for aluminium tubing of a specific size. Is it because you are using the same commercial end caps for different submarines?
If so there is one skill/availability that would really help you with subs - Lathe access either your own or someone elses. End caps with O ring seals are not very difficult to make.

Yes, where to keep a lathe is a big problem for most people. I inherited my Dad's Myford lathe but had nowhere to keep it.
I now compromise with a US made Taig (Known as a Peatol in the UK) lathe which is not much bigger than yours. With riser blocks fitted (a lot of people forget about riser blocks) I can turn 110mm diameter polycarbonate without problems.

I have a large sheet of 6mm "smoked" tinted polycarbonate sheet which I found by the bins at the flat I used to live in. (I think it was probably used as a security screen somewhere. No, I didn't take it during an armed robbery!)
I bond 3 layers of this together using Plastic Weld. (Drizzle the solvent on and quickly clamp it up. Best done outside.)
Let it mature for a day and you have a good thick blank which is good for end caps.
I'm sure you can buy thick polycarbonate but it will probably be expensive. Polycarbonate is my favourite material for lots of things - incredibly tough but easy to machine. I used to to have trouble cutting it with power tools - the cut sticks back together. Following Nigel's suggestion I now use one of new generation (and quite cheap) handsaws. An 11 teeth per inch (Stanley Fat Max from B & Q) one seems to work well.

Just a word off warning Guy's,if you want to cut poly wet just use soapy water and a course blade,don't use thiners on poly it will attack it and over time it will craze,the same applies to thread lock(loctite etc).
