The differences you describe are pretty typical. Like Neal pointed out, you load your kiln to take care of these idiosyncrasies. You can help this with a soak, and varying the cone your firing too. The hotter you fire too, the more noticeable the fluctuation. I used to fire a kiln sitter with multiple thermocouples, titrating the control manually. Drove me crazy, trying to get that perfect even firing. If your interested in having more control with your skutt controller, you can add zone control to your existing controller. For the cost of a couple more thermocouples, and drilling two more holes, the controller will keep those zones alittle more even.
-
Does your kiln have zone control, are there three thermocouples or just one?

The Genesis is cheaper, but my wife's sanity has value also. It'll be easier for her to fire if there is continuity between the various kiln bodies we have. I don't really care about the app stuff, I've had wifi cameras on my kilns for a couple years. But I do like the very visual way of creating, and tracking our programs.

I had to build my own box for the olympic controller, so I could get zone control. I'm trying to just mount it to the wall, or a pedestal, so the mount isn't much of a concern. I used a skutt control box rewire kit to build it, because I always have spares. My only wonder, for now lol, is the difference in resistance between the two kilns elements. I couldn't find any info on the olympic 2327 element resistance. Skutt, no problem

I am looking at upgrading my skutt kilns to the newer touchscreen interface. Pretty straight forward process. But can you use one of these interfaces on on a competitors kiln. I have a couple old olympics of similar size, ect to a 1027. They are about to become, individually zoned, relayed, ect. Perfect time for an upgrade. I know Bartlet has the Genesis programer, but I like continuity if I can get it.

A reduction might be a fun idea for a kiln I'm about to replace some elements in.
-
I hadn't considered coating the elements. Could you create a reduction atmosphere in a kiln with coated elements?
-
I've read that it also increases the efficiency of the kiln. I do fire alot, and the fact that my kilns are 20-30 years old and have been rebuilt a couple times, durability wouldn't hurt. Are there any competing products?
-
I have a couple 1027s, an olympic and a 1227 skutt kilns, the brick are good, usual wear. Was about to start going through them one at a time. Elements, converting to three zone, upgrade some control boxes. I thought while the elements were out, I'd consider spraying the body's with a refractory coating. I have heard of itc, but was wondering if there were any like products, or better products on the market. Even thought of coating my thermocouple to prolong it's life, especially now that I'll have three per kiln, yikes.
-
Everytime I rebuild a kiln, I try too do upgrades that should make them last longer, run more efficient, safer, ect. I'm considering using an ITC coatings this time on the kiln body, and if it goes well, add it to my upgrade program. I've seen products for the brick itself, and coatings for the elements also. Do any of you have any idea how well these products work, and products that you like.

Adding relays to my electro sitter
Johnmicheal replied to Johnmicheal's topic in Equipment Use and Repair
It's a 2327, with a small electrositter converter box made by Bartlett. I imagine if I'm going to increase to two-three more relays, I'll have to think about a new box too. I can do that, but if I'm going to go that far, I'd just assume mount the new box on the wall, and run all the cabling too it. I've done it before. I just couldn't remember if the relays on amazon would work for this application. They are quite a bit cheaper than the skutt equipment. -

Johnmicheal replied to Johnmicheal's topic in Equipment Use and Repair
Can I use the same 25 amp relays I use on my skutt, model 2139 relay, or a generic relay https://www.amazon.com/gp/aw/d/B07K2QZ97Z/ref=ox_sc_saved_image_8?smid=A3M6TV4DFEXUV8&psc=1# -
I have an older olympic kiln that I added an electrositter from bartlet. I want to change from the single thermocouple to two or three zones, changing to multiple relays. Can you tell me the model/brand/spec of relay to use to make this change.

From an earlier post, these are the bearings I used to rebuild my RK There are the 3 different sizes: Kit9705 6204-2NSE Nachi Bearing 20x47x14:Sealed:C3:Japan Kit9706 6205-2NSE Nachi Bearing 25x52x15:Sealed:C3:Japan Kit9703 6202-2NSE Nachi Bearing 15x35x11:Sealed:C3:Japan

Heat it, the aluminum head will expand better than the steel shaft. I've done it before, about to do it again, lol. Even with a healthy coat of antiseize applied it still seized.
