2) Tabbing and slotting

Assembly was relatively straightforward once I had found the instructions and, more importantly, read them. Laser cutting makes for accurate dimensions and facilitates use of tabs and slots to ease construction. Lots of clamps were needed, also weights to hold everything down on a slightly under-sized assembly bench. The X-shaped stiffeners (not shown in the photo) were a bit fiddly to glue securely, and still have a tendency to come loose if a board is flexed during transport.
