So....after the first attempt was less than ideal, I decided to make an injector. I used 1.25" copper pipe (2' section), a 1.25" to 3/4" reducer, a 3/4" to 1/2" reducer (they fit together with no 3/4" pipe needed) and a short piece of 1/2" pipe., and soldered it all together. Then I drilled a small hole the same size as #10 copper wire in the main tube and soldered it in place. Drilling and a cutting wheel made the locking notch on the nozzle to lock the nozzle in place when injecting.
The first shot was a failure, so I increased the thickness of the legs and made the air relief vents larger. Lubed it all up with some worm oil, installed the air pocket nubs, and tried again----SUCCESS !!! Much better looking, very minor trimming needed. I made 4 without glitter and 4 with....man, that crap gets everywhere !!!! Going to send the first batch down to my son in Mississippi and see how he does.
