In Topic: Test Firing Of Rebuilt Paragon Snf24--Pretty Good, I Think. Maybe.

18 September 2014 - 07:56 AM

I suggest that you adjust the Kiln Sitter with a firing gauge and add witness cones to several shelves. I agree that the witness cones are more accurate than a pyrometer.

 

A quick diagnostics pointer for your SnF-24: The elements in the SnF kilns are wired in series. If the top three elements light up, you know that all the elements in the kiln are working. This is because each of the top three elements is wired in series with other elements.

 

Your kiln project was like attending an in-depth maintenance seminar. Congratulations on getting your kiln running.

In Topic: Is My Gare Pf2329 Kiln A Lemon?

02 September 2014 - 08:13 AM

 I've spoken with kiln element makers who suspect that it's the kiln elements that aren't actually 208 volts. Evenheat suggests I take an ohm reading but that entails me hiring someone again to remove all the elements, take the readings and rewire the elements. I have consistently forked out cash for this kiln that has never worked right and I'm discouraged. I can spend a few hundred dollars to get someone in and take the readings and determine whether Evenheat sent me the right voltage (i checked with them several times and they insisted they were 208) If they're not 208, I sure hope the company corrects this problem by sending me new ones. But are they going to pay my expenses incurred to figure that out? And if they are 208, what could be the issue? I've got a 3 phase 208 v electric supply and a 208 v 3 phase kiln with new elements, new thermocouple and new relays. The controller is super basic first generation and i'm not getting any error messages. Could it be a transformer issue?!

You can measure the resistance of the elements yourself. Look at the wires going to the element connectors. If only one wire goes to each element connector, you do not have to disconnect the wires to check the ohms. If more than one wire is connected to each element connector, disconnect the wires from one element connector. Then check the ohms.

In Topic: Electric Kilns Now Described In Cubic Feet, Why?

27 August 2014 - 05:16 PM

i guess i wasn't watching when this changed.  i cannot even guess what a description stated in cubic feet would look like.  a 7 cubic feet kiln?  lots of math images come to mind, all of them frightening. kilns have ranged in size from the old coffin shaped ones to rounds, decagons, cubes, etc. of various dimensions.  what counts is "can i get it through the door?"  and " will i need new shelves?"  who cares how many cubes will fit inside it?

 

ok, kiln guys, why the change?

I use cubic feet to compare the firing speed of kilns. The lower the cubic feet and the higher the watts, the faster the kiln will fire. You can make a quick mental calculation from a list of kiln specifications.

In Topic: Dang!&*&$#--Having Touble Getting Elements To Lay In Groove...

18 August 2014 - 04:14 PM

Thanks ya'll. I'll keep working on it. I may have to nibble a bit on the firebrick to get the pins to go in at an angle. Maybe some bent-nosed needle nose pliers will do it. I hate to put the pins straight in. AHHHH just had an idea. I may be able to dremel off some 45 degree places on the back side of the lip that's causing the problem. I have an old Jenkins kiln that I hauled off for someone. The element channels ARE beveled at a 45 possibly so pins can be inserted that way. hmmmm               ja

The SnF-24 should not need element pins. If it were my kiln, I would not alter the brick grooves to make room for the pins. Push the element all the way to the back of the groove where the firebricks meet, the element should lie flat in the grooves when you fire the kiln.

 

The video link shows an employee installing an element at the factory. (It is near the 3 minute mark.) Notice that he pushes the element into the groove and maintains a constant pressure against the element. If you let go of the element half way through the installation, the element will not stay in the groove later.
