liquid hide for lubricating and long working time, all at once, with experienced wife helper, pre-adjusted clamps, chamfered tenon ends to make insertion quick, parts numbered for where they go and their orientation and laid out in order.
With nothing to cause pause we can get this assembly together in 10 min or less, well under the max working time of the glue.
The drawer runners presented a step that would be slow. I have arranged this joinery so that they can be slid into place later.
I assemble a case all at once. All the still loose joints can adjust so that everything wiggles around and comes up square before the glue sets.
