Then, I fitted the second (uppermost) rear panel. This is a straight fit, without mortise and tenons, but needs to be held steady while curing with cramps. I also added angled styrene bracing to limit future movement.
After that, I bonded the lower section of the front three plates in place. I wondered what the holes (one indicated by a red arrow) were for in it, as there's no mention of them in the instructional pdf., nor a picture
Eventually, I chose to fit the plate this way round because the holes are likely to be needed to adjust the Henntec unit.
When fitting the front panel (2nd in the tree plate setup), I clamped and wedged some bits of styrene (of the correct gap dimensions) between the two plates to keep them from flexing out of line, as the panel was pressed home.
The inevitable gaps have since been filled in internally, and externally, with Milliput (extra fine). On the external joints, I also simulated stretches of spot welding- though these are not likely to be visible when the tanks upright. Still, it seemed worthwhile.
The back section (especially the towbar) will need a wash and brush up, and general tidying, before it encounters primer.
The springs allow the arms to swing almost horizontal, but any more than that might tip their elasticity range beyond recovery.
