Figured I'd share. I made myself a clay extruder. I wanted to use one but didn't want to pay $4-900 for a commercial one. I used a 4.5 inch diameter DOM steel pipe 24" long and 1/4" thick. I lathe down a plunger and welded it to a bit of black pipe. Then made some more welds for bolts and attached it all to a vertical pole. Made a plate for the dies to push up against. Then bought and cut up a cutting board from the store and drilled it to make dies. Seems to work fairly well. Will need to experiment with different shapes as I need them.
