It’s time to build the axles so the tires will have some where to go, then springs.
Used the Shop Smith to drill out the square axles 1/2”so 1/4” dowels will be used.
With parts this small had to use clamps to keep every thing square and in line but with full size lumber the fence and miter gauge would have done the job.
Build the differential and checking out the drive shaft, much of it is just set in place to figure out the next step, making the pivet for the rear wheel Assembly.
I spent most of the day making curved springs but not to happy with them so we’ll have to look in to this some more.
