Beautiful work and some interesting set ups. Keep up the good work.
Some other pictures
Still running ! but fitting takes a lot of time
Here is the four half dive shaft.
and the mess on my workshop
Here is the blank mounting of rear axle. Included: differential, Hooke's joint and frame pivot.
The last pictures are the machining of hexagonal inside hole.
Zapjack--that rear axle assembly has spurred a memory. Back in the 1930's and 1940's you could buy an "Autotrack" kit to convert an automobile to a tractor. There were two very large steel wheels with an internal ring gear on them, and a separate axle for those wheels to mount on. Also provided in the kit were two small pinion gears which mounted to the original car axle. The car body was removed, and the car's rear axle mounted to the frame without springs. The separate axle for the large steel wheels mounted to the frame far enough forward of the car axle that the pinion gears on the original car axle mated with the large internal ring gears on the wheels. They had awesome power, but you had to make a large box and attach it to the cars frame and fill it with rocks to get traction to the wheels. They had so much torque that a few people were killed when the rear wheels hit an obstacle that prevented them from turning and the car chassis "walked" right up the internal ring gears and flipped over backwards crushing the driver.----Brian
Those conversions were sold buy Sears, Roebuck and Company.
Thanks Brian for those informations.
Really amazing kit's
I translate it in french and publish on local forum.
I have just stumbled onto you build and am very impressed. You do beautiful work and I will be following your build.
After lot of troubles for the machining of the small 14-tooth gear (chain driven) the last was the good one
Now the cast iron flywheel and clutch.
To get a maximum accuracy, center in bronze is machined together with the flywheel
Next step of the clutch lever bearing
Complete from bar-stock
That is one neat crazy universal mill, What is that?
Great looking work!
Raw parts from barstock
Here is the machining of the clutch pads. It's not a centrifugal clutch, but drive by hand-lever.
The Ferodo is made from leather.
Nice work, almost identical to the clutch arrangement on my Case traction engine I built. Keep the pictures coming.
Some view with blank mounting
All the parts are first sand blasted before painting
coat of primer, two coats of RAL7031 (grey) and a finishing coat of two component varnish
Very nice work! Looks like the full size machine!
