JAG/Painter  Foot Drive Assembly

 

 

JAG/Painter Main Foot Drive Kit

The Foot drive was redesigned by JAG from the original Dave Painter design.  This is a one time project, and not a club run.  I am not aware of any plans to do a club run on these, but who knows....

-- Single piece shell for easy assembly.

-- Off shelf parts modified for the design.

-- Uses the NPC motors

 

 

 

Pre-assembly :  All the parts in a row.  Jerry had already put the sub-assemblies togeather.  :-)

Assembly:  Axle is pressed through the wheel/bearing.  I turned the axle in the lathe with 600 polish to make the fit a bit less tight.  Belt is installed with the axle per Jerry's instructions.

Assembly:  This was my cut in the foot to allow the motors to pass (and also allow the drive assembly to be inserted into the foot shell while fully assembled).    Jerry came up with a slightly different cut that looks a bit better cosmetically, but the cut-out is behind the battery box, so anything that works for your motor will be okay.

Assembly:  The top cap on the motor has to be ground down to fit in the battery box.  I used a chop saw blade and ground it on the side.  Probably be easy if you have the right tools.
