Fruehauf Trailer

Geoff, I would probobly put a bit of 100 X 6 flat on it's 6mm edge along the centre line of the RHS, and then a a bit 75 X 12 flat on it's 75mm side along the bottom of that to form a beam, 50mm stitch weld every 100 or 150mm. It's easier and stronger than making a truss.

G'day, I tried for rego today but was told I need a roadworthy check first, and that was after they found another form for me to fill out.(thought I had them all covered) I phoned and made a booking but will be advised when they can do it. So then I need to drive 65 km to get permit (24 hr only) and pre-pay roadworthy, travel back, get PM and trailer and drive 70 km to different town to get inspection and return.
