This is a problem due to be solved this summer. With the introduction of new machining centers we can now make the barrel extensions in house as well. This is a big deal for me to keep rates competitive. I learned a long time ago that relying on outside vendors is a dicey game. Getting shit under my roof has always been advantageous (for everyone) so it'll happen with this too.
It's coming. . . Let me get the stuff we already do completely lined out (5 axis, while super cool, is a bit more tedious when programming and getting things wired super tight).
Soon!
