Cut the members (a), (b), (d), (e), (f), (h), and (i) to the dimensions as shown in the lumber list in the previous page.
Make up the two end frames using the drawings below as a guide.
Note that the inner seat frame ends (b) are a different width than the outer seat frame ends (a) by 20mm (3/4") which is the thickness of the seat slats.
First nail and then bolt the horizontal members (a), (b), (f) to the vertical members (d) and (e) with 10mm (3/8") coach (carriage) bolts. The spacers (h) and (i) can be fixed with screws.
