insers the prepared tube, fill with soft clay, and crank the handle.... just like a plydough machine.... on;ly more useful.....
this clay gun cost under 10$ and makes enough tubes for 3 diffrent die heads, though the parts are cheap enohugh to make a bunch.
you will need:
a caulk gun frame- I picked up this one for 4.95 at the local hardware store- this is a 13 inch gun, designed to use the "regular" sized tubes of glue and caulk
a length of 1 1/2 inch schedule 40 PVC Pipe, this peice is 5 foot long and cost $2.30
1 1/2 inch caps to use as die heads i bout 4 at 70 cents a peice
1 1/2 inch test cap this was 35 cents for 2.
you will also need a marker, a hacksaw with a sharp blade and a mesuring device.
Step 3: Fit the die cap
keep the holes smaller than about 1 inch in diameter, (YMMV). this pattern makes a rope if you twist the clay as it extrudes...
Step 4: Test cap plunger seal
add a glob of glue (liquid nails) and glue to the piston head of the caulk frame.
let dry for a hour or so.
