Of course this means taking off the top, then one layer of very itchy insulation (much like fiber glass insulation for the home) followed by another layer of fiber blanket just above the elements. This showed that the elements that are inside ceramic tubes are wired six to a unit. This is a three phase kiln so each phase took care of six lengths each.
The only way to get at the elements to spread the coils apart was to ease them out of the tubes, then straighten the tails and try to get all six out without breaking them. Guess what! I broke the first one. After some calm reflection (you guess how long this took!) I decided to have all the elments replaced but on the outside of the tubes as is more normal.
The element coils are now on the outside of the tubes, the insulation back in and the top screwed down. These two items are among the first finished in the rewired kiln. Please don't ask how much this has cost.
