I had a plan that 'he who builds' doubted from the start to hinge my caravan table to increase my ability to reach the overhead cupboards from either side, not being squished between the table and seats. As the whole thing drops down to fill the gap and form and extra bed, the panels needed to be 720mm wide. No single timber panel would match this, so I was lucky enough to find @specritepro beech timber 1.2m×600×16mm on sale @Bunnings as I needed to create a longline kitchen benchtop that hinged over the gas stove - small panels were perfect to cut to lengthand hinge along the join.
Only issue I had was the joinery method used by 'he who builds' was to attach the back panel to the wall mount, tip it up and vertically attach the second panel with a piano hinge from underneath. This created a gap we were trying to bolster from below so the table didn't dip in the middle once the leg was reattached. The only solution was a 3mm strip of timber ply (we had no 720mm panel left that wouldn't split along the joins) which 'he who builds' proceeded to glue and flat head nail. Totally visible when table is halved. Oh well. If that's my only complaint....I'm still happy with the end result.
