suz davis Posted July 19, 2022 Report Share Posted July 19, 2022 it seems my kiln has been underfiring. i am trying to turn the set screw on the trigger plate of my kiln sitter but it won't budge. it's now soaking in blaster goo. this is a lefty loosey, correct? any suggestions to free it up? thanks!

Babs Posted July 19, 2022 Report Share Posted July 19, 2022 It is usual to adjust on the rod which passes from outside to inside of kiln and sits on top of the cone, not the plate. There is a thingie, guage, you can get which will hold that pin and cone support in correct position for adusting to. If plate is dropping too soon, it may be that that rod is worn on the kiln side. Adjustment by moving the "peg " along the rod, towards kiln body, to allow the plate to sit more vertically and thus drop later has to be done with caution as if too vertical it may not drop and so kiln stays on... Have you got a cut off timer seperate from the kilnsitter? Quote Link to comment Share on other sites More sharing options...
suz davis Posted July 19, 2022 Author Report Share Posted July 19, 2022 thanks for your reply! my kiln sitter doesn't have a timer. it's model k, i believe. i am using the gauge to help with the adjustment. i will definitely look into what you're describing! i babysit my sitter, especially when it's close to time and check my cones. definitely don't want to overfire!

Babs Posted July 19, 2022 Report Share Posted July 19, 2022 Yes the timer has to be seperate from sitter . Cuts the electricity to kiln after a set number of hours. I used to set mine 1/2 hr aftr my estimated firing time ended, in case I slept etc. Nursing a sitter, the only way. Quote Link to comment Share on other sites More sharing options...

The claw is set at 1/16" from the plate when the plate is all the way up. The plate is then adjusted to the correct position using the firing gauge for calibration. If the kiln is firing too hot, the plate is lowered. If the kiln is firing too cool, the plate is raised. @suz davis KILN SITTER MANUAL Like Babs said, check the condition of the rod. If it is worn and getting pointy on the inside, or is bent, then it should be replaced. Babs 1 Quote Link to comment Share on other sites More sharing options...
suz davis Posted July 19, 2022 Author Report Share Posted July 19, 2022 thank you!! i inspected the rod and it looks good! i was finally able to persuade the set screw. the plate was off, close to 1/16", which is probably why it's been underfiring! i am testing it out now and will check it regularly as it gets close to time. thank you both so much for your help!!

Too late for me but there you go, @suz davis Quote Link to comment Share on other sites More sharing options...
