Spindle/drum sander

So where did this ever end up?

I’m not sure which “Chuck” Walter ( @wandrson ) was working with, but I’m wondering a couple of things:

  1. why aluminum?
  2. have we found a willing member to try TIGing these parts?
  3. if not have we decided for or against a professional?
  4. if against, where are we now?
  5. are Walter and Chuck willing to share their work so far (I presume there are 3d “sketches” at the least, since there was a 3d printed mockup)?
