New oven
Had a good year last year so at Christmas I ordered a EvenHeat KO18 with Tap controls. Took a little while to get it made, shipped, and installed but it's now all ready to go in my shop.
Last night I got to run my first batch of 440c through and man it this oven a rocket! The Tap controls worked great and seemed to keep the temp even as it went up. I got the 220 version so didn't take long to fire. Total time was 1 hour 25 minute with the soak times included. Blades came out of heat treat at a good R62 with a plate quench. Don't miss the mess of the oil at all! Will temper them this morning down to a 60ish.
Can't say enough good things about my new oven.
