Annual update

This picture is where the project is at this time and represents 12 months work. The turning clutch disengagement mechanism, the gear selectors and turning brake levers will complete the transmission.
The final reduction gears are complete in their housings.




This is the equalizer beam being fabricated.The engine beams and the front suspension have been completed.








This image is not recent but shows a view not available to owners of the full size tractor.









The equalizer beam is now mounted to the engine frames. The engine frames are made from angle riveted to 2mm plate steel.
In this image the brackets to mount the channels to carry the pivot axle have not been riveted in place.

Transmission - Case

This is the drawing from the parts book that was used to dimension the transmission. Measurements were also taken from the prototype in Queensland.






The transmission started out as a piece of 65mm pipe, 5mm wall thickness. It was cut to length (240mm) and carefully quartered on a large bandsaw.






Here I am in my friend Bob Waterford's workshop making the final cut.
















Here are the two quarters of pipe separated by a piece of 6mm plate 240x50mm. This was welded together to form the base of the transmission. The remainder of the transmission was fabricated in a similar way.

This photo has been posted previously and shows the fabrication of the transmission complete.

The fabricated transmission was placed on a surface plate upside down to mark out the bearing centres. It was then clamped to the mill table and the holes bored.
