[Clayart] My new tile floor

[Bryan Johnson]

David's tiles and extruder rabbit holes.
I started with a couple of homemade extruders, moved on to a stainless 4"
North Star.  Which kept me happy for quite a few years. Then a pneumatic
Bailey. I made a 5.5"ID barrel to hold 25 pds, but it didn't have the force
for 1/4" tiles (extruded Skinner blends) and some other unusual dies.
So I  made one that would use a larger pneumatic cylinder. Works fine with
way less pressure.
  For maintaining the pattern while reducing patterns in canes I have found
that having the barrel be close to the size and shape of the cane. So I
made cylindrical and hexagonal barrels to fit inside of the square ones.
I've done some extrusions where one pattern is inserted into other extruded
parts (and then extruded or thrown).  This approach might work for
connecting slabs to make vases. I have pictures on Facebook. Bryan Johnson
