Fiberglass Chopper Gun Ended

Hello -

I'm looking to build our own fiberglass resin chopper gun. It's essentially a spray gun of sorts that will fire both pre-mixed resin (that is thick) and also it will chop up fiberglass and spray that too.

You can see an example here:

Here is a close up of a gun with the chopper:

And here is a product demo selling just the chopper (to reverse engineer)

I assume the core components would be:

- Chamber to hold the pre-mixed resin
- The chopper component for the fiberglass
- The component to fire the resin through the compressor
