Homemade Clay Extruder

Today I made a clay extruder following a how-to video on Ceramic Arts Daily. As I already had a caulk gun, it cost me less than $5 to make 3 sets of a 8" pipe and a test-cap die. I modified one of the test caps, so that I could insert dies I already had. It was very easy to make. As long as clay is soft it works well.

p.s.
If you're making one here in Rapid City, only Lowe's carried the particular test caps I was looking for.
