I was doing some googling for the jars for the hf pc gun and found mod that lets you take a Eastwood jar or any jar and use it.
Did not see the instructions on how or where to cut. What I could tell from the pics.
Cut the hf jar inch or two from the threads. Cut a hole in the Eastwood lid with out damaging the threads. Glue them together.
These mod may work with any suitable jar.
I’ll give it a try.
