VARIANT-K MATERIALS

Ok, this is simply just another way of building the PCM. Instead of a 1 foot Combuster, in this version it is 1.8 feet. The barrel is also shorter, from 2.5 feet down to 1.2 feet. I hope that you can build both variants, sorta double the fun!

Supplies for a Potato-Cannon Mortar Variant-K

**note: 5" pipe & pieces can be replaced with 4" if no 5" components are available

1. 1.2' 3" length of ABS pipe
*ABS is recommended over PVC because if you screw up in the building process, yah don't end up full of shrapnel. Heed these words of wisdom.
1. 1.8' 5" length of ABS pipe
1. 4" (or 5") 45 degree elbow
1. 5" - 3" ABS coupling (also called a reducer)
1. 5" threaded female adaptor
1. 5" threaded end plug
1. BBQ push-button sparker or Spark Plug
1. can of ABS cement
Epoxy (preferably not the 5 minute stuff)

So now that you have the list, pick up the pipe. The building procedure is the same, except for my diagrams will appear to be out of scale, but who cares, they're just there for your referance. Enjoy!!
