The feet

Left: Q85 motor for 2-3-2 design
Middle: Q85 motor for mounting on the underside of the feet U-channel.
Right: Q85 motor for mounting on each side of the feet U-channel.

I will try to make the new drive system.
I now have the motors, only the rest remaining....
The 2 motors on the left are 328 rpm/m and the others 201 rpm/m.
I decided to change my steel feets to aluminium.
I spot welded the feets with my TIG, but I will let a proffesional
MIG-welder finalize them.

Re-done casters. Cut and only tack-welded so far.
