This video demonstrates how to remove a ring from a bell-lift kiln for repair or replacement. Here are some additional notes:
-Be sure to protect the paint from the steel cables with some sheets of cardboard over the top.
-Before you remove the element boxes and cords, be sure to photograph how the wires hook back up
-Before you lift, loosen those rubber rollers so they're not adding friction as you lift.
-Before you lift, those sharpie lines you see them drawing in the video on the fiber lid and the metal base are critical for lining everything back up.
-The steel cables are sized so that the sections have gaps between them as you lift and prevent rubbing on each other.
-Since the safety pins aren't usable in this scenario with everything lifted, PLEASE be careful not to lean into the kiln as you remove the bad section
-As you remove the bad section and put the new one in, watch the element terminal bolts don't scratch the paint
-it is a tight clearance, so you may want to put tape on them to soften the abrasion.
-The leveling process at the end, using that 1x6 wood plank, is a double check to ensure the top cage and bottom cage metal aligned, before putting the vertical metal struts back on.
-When everything is done, ride the bell up and down a few times to ensure the rubber rollers are engaged as much as possible throughout the range of motion (won't be perfect).
