Hello,
>>
>>The Kiln Sitter will not function if the kiln is not fairly level. If
>>the kiln leans away from the side the Kiln Sitter is on the sitter can
>>"hang" and not drop the hammer when the cone bends. The other thing
>>to do is make sure that the cone does not come in contact with the
>>ceramic portion of the Kiln Sitter inside the kiln. This can cause the
>>cone to resist bending.
>>
>>The little metal cone rests can be "dirty" with melted bits of cone on
>>them, or they can be bent downward. They can be cleaned with a flat
>>file. Take them out of the ceramic tube and lay then on a flat surface
>>and file them until they are shiny. If they are too thin or bent
>>replace them.
>>
>>Orton cones have never varied more than one degree + or - since they
>>went into use, so I am sure that the cone is not the problem. As
>>someone wrote the kiln sitter is not a very sophisticated device and
>>there must be a simple (relatively) explanation.
>>
>>Of course YMMV (Your mileage may vary or is your coneage may vary)
