Yeah it has link to tube manufacturers,, I did find some but is the going rate for marine pvc 120/meter(us price)? Slightly cheaper in UK i think.
I was thinking of making a small inflatable dinghy... Probably cheaper to buy one already made but I like DIY.. I contacted a manufacturer...
Anyone though of modifying a pressure washer and attaching a 6.5 hp lawn mower engine as a jet drive? is that possible?
