Mr. McCormick's Reaper Binder - Part 4

Reel fixing, 3 Levers, Seat, Banner/Guard and Towing Shaft

All but the towing shaft are supported by a single piece of wire formed into an ellipse and positioned between the platform and elevator.

Six individual parts are soldered to the support bar. The only way to apply heat for soldering a part without previously fixed parts falling off is to use a heat shunt between the part being soldered and the others. A crocodile clip with a pointy end can be used for this but I used a purpose built tool that is used in electronics product manufacture.

On the full size machine the operator's seat is sculpted and has perforations. On the model it is a flat washer! Can you spot the difference, or even see which part it is?

The banner guard proclaims the manufacturer. Both this part and the bundle carrier were sometimes removed in practice.

The towing shaft is for two horses. It is made from flat brass and is fixed to the machine by wrapping it around one of the big wheel supports and left free to rotate.
