[Spridgets] How it's made. Episode 498 Judson Rotor.

Hey it's snowing here in Pennsylvannia...

Slot chip snow. Thought I'd show you the mess that all this makes.

The last slot has been cut.  Yeeha.  

A little lesson learned (if you are ever doing something like this).  
Apply STP to the sides of the saw blade.  It creates a hydrodynamic damper 
that helps reduce chatter.  Made a big difference.

I have one more operation that I am going to do with the big saw.
I'm going to mill a tiny amount of the outside edge of the slot.
On the worn out rotor this sharp edge would dig into the back side of the
vane.
