Slow day today. Got the diagonals in to support the roof and also act as a seat-back for the rear passenger, and also bracing and spreading of load for the seat-belt mount points. Have turned down the ampage on the Inverter to its minimum, and the welding has actually got not just better but actually quite good. So, before putting in the lower diagonals, the welds of the base had to be improved. Once this was all done, the uprights could go. There's now quite a bit of space for the rear passenger, which is good news, as some of that space can also be used for luggage.
