Reverse Helix tube

Anybody know where I can get a reverse helix tube. I contacted Tim at wild boar prospecting and was told that they would not strip one of there unit to sell a tube. I guess they don’t have any spares for their units. Would like to build one myself if I can find a tube. thanks Ken

  • You may be able to make one. If you had a plastic tube (pvc, blue bell is larger) with another that will fit inside. Cut the smaller one in a spiral fit it inside and pull it out like a spring to give the spiral riffle. Attach with solvent and screws or blind rivets. Have never done this but it should work on larger pipe. You may have to heat and pull the spiral to the shape with a heat gun. Do not over heat or the plastic will become brittle.
    • Thanks Walter
      I was thinking along those lines but using a felixable strip of something and apiling it to the inside of a pvc pipe
