COTS wheels suppliers make wheels that are just as good, but maybe not to your exact specifications. Often times, we had to adjust our shafts/frame to fit the wheels instead.
However, this past year, we machined our own wheels.
Was there an advantage? I would say no.
It was cool looking though.
We will continue to make wheels simply because it gives a greater opportunity for our students to have ownership and use CAD to create what they want.
