Photo of a drafting table inside a workshop. Two vertical plywood strips with slots at various heights are screwed to a steel frame on the white wall inside the workshop, extending down to just above the floor, and a flat A1-sized piece of MDF is mounted across them. The "table" has bolts across the top that fit into the slots on the frame, and can thus be placed into any slot as required; and there are pivoting "legs" from the bottom edge of the table that fit into the slots lower down. So depending on which slots you use, the table can be nearly horizontal or slightly slanted (as in the photo), or completely vertical. The plywood is cheap and brown and worn in spots, not finished nicely. Near the upper left corner of the board is attached a "mini drafter": a thin steel-tube parallelogram arrangement with an L-shaped ruler that can pivot to draw parallel lines at any desired angle anywhere on the board.
