[pianotech] More on Action Cradles

[John Ross]

I was thinking on making the set screws larger.
The ones in my unit are too small.
I already changed them from slot screw, to Allen, which was a help.
But I am thinking that 5/16" like used in my Shopsmith, might be a better size. They hold the saw blade, and sanding disk in place.
It shouldn't be too hard, to drill and tap larger.
It came to me when I was checking my SS alignment.

      Hi Gang:
      I made two improvements on the standard tubular action cradle, especially the one with 4 legs.  To keep the legs tight, I inserted short, round dowels into the ends of the legs so they won't collapse inward as the set screws are tightened.  Second, to make it easy to push the cradle into my station wagon, I brazed two small casters on the bottom of both legs on one end.  Now I can push the action in and pull it out of the car easily without the legs digging into the carpet.
