This is how the set-up now looks on our clay desk work area.
The vice is a screw down type and we didn't want to drill holes in our table so we attached it to a wood cutting board. The cutting board is then clamped down onto the desk so it can be moved to another location if needed.
The drill we are using is cordless so can be a little heavy when the battery is attached. I happened to have a box that was the perfect height to sit the drill on so we don't have to hold it while extruding the clay. To use the adapter, we fill the extruder with clay and attach both ends. We then insert the adapter end into the drill and then place the extruder into the vice so it is lined up and even. There is a piece of parchment paper in front for the extruded clay to fall onto.
This set-up works really well and makes extruding the clay so much easier. The clay we are extruding in the above photo is for our toglet buttons so they are consistent in thickness. We are using a washer we found in just the right size to use as our die. To make them all the same length I came up with my own marking tool. I cut a strip of plastic canvas and cut out sections to create notches for marking. On the opposite side, I cut out notches at a different length. This tool works great when making beads as well.
