Name (and design) change

The dual-saw idea, while worthy, is above my abilities right now.  I need to focus on a simpler design for now (and work up to the saws later...)

The new design, tentatively named "upChukk" has a horizontal drum-style spinner.  The final spinner style is still up in the air, though several options are on the table.  Yesterday, I put one together:
  • 2.5" piece of 1" wide steel bar, with a 1/4" hole in the center (for the shaft) and 3/8" tapped holes at either end
  • two pieces of 3/8" threaded rod put through the end-holes on the steel bar in an H-arrangement
  • the proud ends of each piece of threaded rod are covered in hex nuts
 The end result is a "retro lawnmower"-style spinner with two weighted "blades" (the threaded rod+hex nuts).  The nice thing here is it will be easy to add (or remove) weight from the spinner -- simply cut longer (or shorter) pieces of threaded rod and swap out with the old pieces.

Other spinner possibilities include:
  • a conventional drum made from a black pipe threaded coupler
  • blades made from steel bar
