    Gaslow is great, but I wonder...does anyone make a rectangular log tank that fits in the usual cabinet?

    It's very rare to see a pressure vessel anything other than "round"

    A friend of mine supports his son who has been racing hovercraft for the past 25 years. By 'supports' I mean he does most of the engineering required to fit the engines, exhausts, ducts, and fans, to the basic GRP moulding. The engines are usually tuned two-stroke snowmobile engines of up to 900cc - most are triples. He has gained a reputation in the Hovercraft Club for making various bits - some of which are expansion chamber exhausts. He makes these from two sheets of flat 1mm steel cut to contorted shapes then edge welded. He inflates this totally flat assembly using hydraulic pressure from a hand-pump. Normally required pressure is 700psi at which the exhaust assumes a round cross-section with the various diameters and bends needed. The final operation is to dress the welded seams with a panel beating hammer. With the pressure locked for this operation it is like hitting a solid steel object and allows the weld (and the inverted crease alongside it) to be beaten out. Pressurised fluid is very, very solid.
