I've never done any plastic stuff, but this looks like you made your own plastisol injector, am I right?

Yep.  A couple of them.  Not the first time.  Years ago one of my customers bought a custom mold, and then said, "Hey.  I don't have an injector that will fill that."  I didn't have any either, and I was not really in the injector business so I made three, took all the best parts to make one, and sent that one to him.  (After testing his mold.)  I kept the other two for my own use for many years.  Then a few weeks ago another one of my customers was whining and carrying on (for days) that he needed some more injectors and nobody had any for immediate shipment so I sold him the two old ones I had on the wall.  Then I had to test some new big molds again, and I didn't have any injectors so I had to make a couple more.  These are to big for regular use so I still need to make a couple more.  

I used these two to try working up a process and order of operations to be able to make them efficiently.  I still have no plans to be in the injector business, but eventually I'd like to have a dozen smaller (6 ounce) injectors and half a dozen large injectors maybe a little smaller than these 15 ouncers for those days when I make up my next years supply of a particular bait.  More molds is more efficient, but so is more injectors.  That way you can fill all your molds before you have to stop to clean injectors.  

I never understood why more people don't make their own injectors or have them made locally.  Anybody with a metal lathe can make one.  The first one I made was on an el cheapo Harbor Freight 7x10 mini lathe.

Huh, this is really cool!  CNC machining is really interesting, and the skill-set to be able to manufacture this stuff in response to a need is really solid!  Way cool man, way cool!
