Inside Dimensions: 10" W x 6.5" H x 22.5" D
Exterior Dimensions: 20" W x 19.5" H x 30" D

The LB Series design was inspired by great feedback from the knife making community as well as culinary and long-blade makers. Knife makers needed to use the entire length of the chamber without overheating their blades at the back wall. We took a fresh look at our designs and created the side-only heating element LB Series.

The results are incredible: front to back temperature distribution is dead-nut. Whether you're making culinary, tactical, fixed blades, folders, doing gun work or something else entirely, the LB Series sets the new standard!

The LB Series represents the ultimate mix of bladesmith input and Evenheat design. The LB is quite simply the finest heat treat oven on the planet!

Side-Only Element Design

The LB Series design was inspired, in part, by culinary bladesmiths who generally make long, thin blades. These bladesmiths needed to use the entire length of the chamber without overheating their blades at the back wall. We took a fresh look, got rid of the rear wall heating element, and nailed it.

The front to back temperature distribution in the LB is incredibly even. Positioning in the chamber has no effect and the entire length can be used.

The LB, with it's side-only element design, is the new standard!

Side Opening Door

Heat treating requires the removing of some very hot material from the chamber in order to quench. Everything in the chamber is hot, which includes the door. The doors on the LB's swing out and to the side, a full 180° if you need it. This puts the super-heated door well away from you as you concentrate on the work at hand.

The side opening door is an excellent design choice and makes all the difference.

Cool Touch Handle

The handle/latch on our swing out door is conveniently located at the front of the door, not hidden along the side. This spring loaded, phenolic handle is cool to the touch, is one-handed in design and serves as the door latch as well.

Many thanks to those who have offered feedback on our door handle/latch. We have updated the design to make centering, inserting and all-around operation cleaner and easier!

Door Shield

The LB's feature a door shield to provide protection against firebrick damage as well as to reduce the temperature seen at the door and door handle.

2200°F (1204°C) Maximum Temperature

The maximum usable temperature for the LB models is 2200°F (1204°C). This maximum is well within the range for the vast majority of steels used by knife makers and machine shops.

Swing View Control Enclosure

The TAP and Rampmaster temperature controls used on the LB's are fitted into our Swing View Adjustable Enclosure.
The Swing View is a pivoting, swing-up enclosure that allows you to rotate the control to a comfortable viewing and programming angle. Once you're done, lay it back down to see it from across the shop. It's that simple.
The swing view pairs well with TAP touchscreen control as viewing angle can be perfectly aligned. You'll love it.

Strong Stand and Tool Rest

The LB's feature our updated stand design that delivers a strong, supportive base and tool rest.

Quiet Drive Solid State Relay

Evenheat's Quiet Drive Solid State Relay System does away with the mechanical relays traditionally used in kilns and replaces them with solid state relays.

 Traditional, mechanical relays wear out and fail at some point. They have to and they always will. Not so with the solid state. Solid state means there are no moving parts, nothing to wear out and nothing to replace.

 Solid state also means superior heating element operation resulting in tighter temperature control, longer element life and enhanced performance.

Controller Selection

Our most popular control is the TAP which combines a large touchscreen with superior performance. The TAP was designed from the start to work with all firing and heat processing styles.

Our Rampmaster and Set-Pro controls offer full firing control in a more traditional 4-digit layout.

TAP Touchscreen Smart Controller by SDS Industries

The TAP is our most popular temperature controller: its wonderfully simple operation, excellent control capability and well laid-out touchscreen just rock.

Nowhere is simple-use more evident than in the single touch needed to access your ceramic firing schedules. Just touch the Start key and all of your schedules are immediately displayed for selection. Schedules are displayed in full, easy to read text.

The TAP comes preloaded with multiple ceramic firing schedules as well as virtually unlimited space for your custom schedules. Creating your custom ceramic firing schedules is easy and relaxed. The TAP walks you through the process with on-screen displays and text that are easily understood and followed. Once created, your schedules stay as long as you want them.

Temperature control is tight and on the mark. Overshoot and ripple are kept to a bare minimum, particularly when coupled with our Quiet Drive Solid State output. Consistency is not an issue as the TAP performs reliably time after time.


The Rampmaster 3 is our traditional full featured control and features a 4 digit display. It offers two programming methods depending on your needs and experience: Custom Mode and Express Mode.

Custom Mode is a programming method that allows you to define all aspects of the firing from temperature rates to set points and hold times. This programming style is perfect for heat treating and custom glass firing programs. Custom Mode offers full artistic control.

Express Mode is a programming method designed exclusively for glass work and offers an easy, 3 step programming process. Simply key in your glass COE, firing style and firing speed to create the firing program. It's quick, it's easy and it's accurate.

The Rampmaster 3 control will work with our Quiet Drive Solid State Relay System. This is our standard controller offered.

Loud Alarm Option

Cut through your shop noise with our Loud Alarm Option. The Loud Alarm sounds at an irritatingly loud 80db. It will definitely get your attention so you'll never miss the opportunity to properly quench again.

The TAP Smart and Rampmaster III controllers support a built-in jack for an easy install; simply plug it in.

MK Blade Fixture

Our blade fixtures were designed specifically to hold your blades vertically and securely. They're stable and are designed to provide ample space for foil wrap inflation. This fixture will hold 6 blades on the ceramic pegs.

Our MK 2 Blade Fixture is designed to fit the LB Series chambers.

Power Interrupt Switch / Automatic Lid Shutoff

Our optional power interrupt switch removes power from all heating elements as the door is opened and reapplies power as the door is closed.

The switch used for this feature is a true safety switch and is designed specifically for safety applications. Those wishing to enter the oven during use should strongly consider requesting this option as an added measure of safety.

This feature allows for the kiln to not overfire (and overheat your knife steel) due to being open while in use when the door is reclosed.
