 Feed Cone
Feed Cone Development. The feed cone has proven vital in the two part rotor design. We're still playing with the design but the results so far have been great.
Base section op1 First attempt at feed cone upper portion. First attempt at the lower threading and seal design.

This is a threaded prototype. I didn't like the design. It was a good threading exercise. This is the latest bolt together design. Drilling the top of the feed cone.

Drilling the feed cone for the feed tubes. Tapping the feed cone for the tubes. The finished feed cone. The feed cone forces all the incoming oil to the back wall of the rotor. No splashing and all the oil must work from the back forward.

I thinned the bottom plate. The original prototype was thick. This is the drilling and counter sink operation. Experimenting with angled feed tubes. The angle on these are a bit steep and the tube is too short. The angled tubes will allow us to use this feed cone with earlier one piece rotors. Installing the stainless steel nipples onto the feed cone. Using the old Leblond lathe as a giant pipe wrench.

Prior to installing the o-ring it should be lubricated with a little silicone grease. This makes dis assembly a lot easier and allows you to rotate the part to align the screws. O-ring installed. Two feed cone assemblies ready to ship to customers.

It is visible the effect the feed cone has on separation. The dirt line is clearly visible where the oil enters the machine. I am amazed with the results. This line was formed after adding 2 liters to the rotor during testing. New feed cone installed. This is the assembled rotor.

We've eliminated the tubes from the feed cone. The bottom has been replaced with an angled plate that forces all the incoming material to the bottom of the rotor near the outside edge. The oil then must rise 4 inches before it exits. This is the bottom view of the re-designed feed cone. The incoming oil passes through the slots and is forces along the angled plate to the outside edge of the rotor. We have totally re-designed the rotor mount and the feed cone.

This is the new mounting. You can remove the rotor while full. This is the feed cone. No tubes or slots to prevent the smooth feed.
