Fabricating Your Own High Performance Cone Pipe

[JC-SuperJet]

To make your Chamber Die, just make a Fiberglass "Splash" Copy of the Chamber. Split in 2 halves.

Pour high strength Quikrete into each halve and let cure. Now you have some Die Molds.

Use the Quikrete with no rocks in it: Cement.

You might need to reinforce the Cement Dies with Wire (like Rebar) or Fiberglass mix.

Helpful information. You can try to do it. It seems to me that if you find an adequate form, it can work out.
