Hi Joe,

?

From memory the seat base (B29) is folded into a square and attached to the footplate (for want of a better description) this hides the chassis fixing not.? The seat top (B31) is curved to fit the seat base with the two little holes at the back.? These holes take the seat back (B30) which is very delicate.? This part has a large square sacrificial support at the bottom and the seat back cross member at the top.? The cross member is folded 180 degrees back away from the half etch lines and soldered to the two thin uprights.? Then you can remove the big sacrificial square which should leave you with a ‘U’ shape of the cross member in front of the two legs.? The bottom of these legs locate in the two holes in the seat top.

?

I hope that helps a bit.

Cheers, Robin
