 New Rotor 2013
It's 2013 and we've been hard at work on a new rotor design. This rotor is basically the same height and diameter of the two-part rotor but doubles the cake holding capacity while increasing the volume of of the rotor by nearly 30% to a whopping 3/4 of a gallon (2.8 liters). Here are some of the machining steps.
After sawing a 34 lb billet on the band saw it is first faced on the manual lathe. Next the billet is moved to the CNC lathe to be roughed. The billet is now faced and the OD has been taken to rough dimension.

Partially drilled for the ID operation. Taper mount machined. Splash ring feature and remaining ID machined.

Into the pie jaws to start the second operation. Faced and drilled to start hogging out the inside. The inside opened up.

After spending the entire day modifying tooling and writing code I have the rotor roughed out. I need to order some different inserts for the ID face grooving but overall I'm happy. It still needs a lot of fine tuning. It's starting to look like a rotor. Finished rotor. Dry testing the rotor on the machine. Runs smooth.

Lid is drilled on CNC mill. Pie jaws ensure repeatability across all parts. Next it will be deburred by hand. Rotor bottom has been drilled and deburred in preparation for the installation of the captive nuts. Captive nuts have been pressed in using custom fixture.

The feed cone is the same as with the dome topped rotor. The slope creates a clumping surface for the particulate to build on before being forced to the back wall of the rotor. Rotor in operation. Volume is about 3/4 of a gallon (2.8 liters). This photo shows the mist of vapor coming off the rotor during operation. This is a test with water. The vapor is a very fine mist. The camera had a hard time picking it up.
