Hi John,

Several years ago I built a 9 x 9 x 9 test kiln for 120V/20A. It is down
at Arkysanto, my AZ place, but I'm up in OR 'til New Years. Drop me a
line after the 1st and I'll send pix and a part list. I used a
Robertshaw Infinite heat controller and wound the elements myself. The
bricks were K26 IFBs, backed with 2" of fiber and a metal case. I cut
the grooves with a ball-shaped rotary rasp bit running through slots cut
with a masonry blade. Wore out the $2.95 bit, but it did the job. Works
like a dream.

I have seen many requests over time for test kilns. I have books on
building fuel fired kilns. But I have never seen anything on making an
electric test kiln. So, are there plans out there for making one? I have
infinity switches, I have some coils, but how can the be assembled
matching the power requirements of the coils to the switches, and
balancing the electrical load. Waht about building the case for the kiln
... bricks, outer shell, grooves for coils etc. If an electronic
controller that is fully functional can be a money saving hoebult
project, why can't making a test kiln be a cost effective homebuilt project.

I'm game. If anyone has as instruction set, please let me know.
