The wheels and axles where
mounted on bearings which were attached to the journals. The levers and
rods to operate the brakes and direction/speed were made and painted.
The journals where built up from
1/4" bar stock. You can see in the picture below the 2 tabs on the
journals (like the ones on the frame) to hold the springs. The journals
are kept from sliding off by a bolt (below right) that sticks out and
catches the tab on the journal. You can see the tab on the journal on
the picture above. Makes it real easy to remove the axles/wheels.
The engine selected was a Briggs
& Stratton 5.5 HP with electric start. The transmission is a Tecumseh
hydro-static. A similar setup was used in my wood switcher and it
operates excellent for this application. They are connected via a belt.
Had a bit of wiring to do like
the starter, charger, lights, compressor, switches, battery, etc.
This is the underbelly showing
the drive chains, exhaust, etc.
Here's the frame and drive
system completed. The air tank was mounted on top of the console and
put the pull starter (backup) on top of that.
