Had some time to sit own and plot a design with real world dimensions (or close to it) that I will be starting on soon.
Essentially, this portion is 5 drawers, a 2 burner gas cooker, 2 prep spaces & a serving bench an a few bits an pieces added for function or to occupy space.
The drawer will be supported by two 50x50x3 angle irons running down the length of the drawer on each side, with a length of 25x3 bar stock welded to the top to give appropriate overhang for the runners.
Final decided length is just under 1100mm and width at just over 400mm. The side table is 1000mm x 350mm.
This is the frame of the drawer. I made a couple of changes after this, mainly raising the unit another 50mm in height to allow for more usable drawer space. The skeleton materials weigh in at ~14kg by math.
decided on 2mm 5005 grade aluminium for the bench tops, sitting on 12mm marine ply for backing. Not counting the drawers, we're at ~17kg
At the end of the drawer is a door on a heavy duty piano hinge. This swings 90 degrees out allowing access to the slide out table, locks in place & then provides a mounting point for the slide out table.
The slide table has 2 tangs on the end that fit into corresponding points on the door. There is also a 3mm tongue on the drawer that fits into a slot on the slide table to provide a guide & further support.
Although not part of the design in pictures, there will be a 400mm wide aluminium splash back that folds up from the closed position flat over the surface with a further 240mm section that will fold over the front and lock into place, ensuring the drawers do not rattle.
On the top of drawers for a moment, I am thinking of a magnetic mat at the base and using a metal set of cups, plates, bowls etc to eliminate rattling as well as soft close runners.
The slide table will also store a telescopic aluminium tube leg inside which will fit into a plug assy on the end to provide the support on the end.
I estimate the drawer to be around 38kg with the drawers, slide table, splashbacks etc.
The bar stock to build the frame is not expensive, so this will be my first trial. The thing that is worrying me at the moment is the small size of the unit overall. I hope its enough particularly in the size/weight ratio.
