New Feed Tube
For the longest time we have used a threaded nipple as the feed tube. This worked well and was really simple. When we changed the feed horn recently we decided it was time to change the feed tube also. We have discussed this change for a long time. I am very happy with the results. Now you can install the lid, then simply push the feed tube into position. This make removing the lid a lot easier.
We started by mounting the lid to an 18 inch face plate. The face plate has been grooved to ensure the lid is centered. After the lid has been drilled and bored to dimension, an o-ring groove is cut. The o-ring ensures a tight seal to the feed tube. This is the feed tube installed.

This is the feed tube partially removed. Feed tube from the bottom side. This is the complete feed tube. I can be removed easily simply by pulling it out.

The new rotor feed horn is necked in very tight to the feed tube. By turning the lid we can ensure the tube is in the center of the lid.
