+1, thanks for sharing that, your lube flow control method is a stroke of genius! If there are some slight issues with hardness and size, that seems like a small matter of changing spring rates or making some part of the system adjustable for a better balance. The fact that it will work in just about any press having the larger thread size is a big plus and would save costs.
Frankly, I've been wondering for years why Lee Precision hasn't come up with something similar using standard dies just like their push-through sizer system, but with a lube reservoir and valve system of some sort for lubing with stick lubes.
Watch out, you might need and international patent soon!
