Couldn’t see one in the space so I’ve made us a clay extruder, they’re very useful for coil pots or mug handles - and if anyone wants a more complicated profile you can easily laser cut one from scraps
Steps to use it:
1: wedge up a cylinder of clay that’ll fit in the metal tube - if you want long coils make sure to wedge well because any air pockets will break the coil midway
2: place clay inside the metal tube, and put the acrylic end cap on, with an acrylic die between the tube and the end cap
3: stick the plunger in the other end and extrude just like using a silicone gun
4: clean the tube out well! Dry clay inside an extruder is a pain in the arse to get out
Happy coiling!
