Is your current heat treat method involving the forge dipping dance? Heat soaking your steel by standing in front of the forge and pushing and pulling for 10 minutes +? Are you still using the eyeball method to guess your temp? Jen Ken has you covered with their Vertical Air Bath 16 Kiln. Their unique design allows you to suspend your blades vertical. This helps to prevent warping issues that can happen in side load kilns. Built here in the USA with safety in mind, they come standard with an power interrupt lid switch so you wont be dinging your blades off live elements when loading or unloading. Built for batches the Vertical Air Bath 16 can hold a dozen or more blades in one load! Better yet, the configurable baffle design allows you to process all kinds of different shapes at the same time. That saves you time and headaches. Shop Jen Ken today and take some stress off your blades, and your life!
Here's how other kilns work... Blades are inserted into a standard front-loading horizontal knife oven for normalization, hardening, or tempering. As oven temperatures increase, blades can bend and warp as a result of the stress of leaning on their sides. Another cause of blade warping in traditional front-loading kilns is uneven heat distribution. A standard front-loader heats from the sides and the back, creating more heat at the back of the kiln. This causes the front door area to get cooler and cooler. The uneven heating causes the tip and body of the blade to be much hotter than the tang, resulting in more internal stress and warp potential, not to mention that the blades in the middle of kiln get the least heat from the coils. When the front door is opened, and the red-hot blade is removed from its horizontal position, it is carefully transferred to the vertical position on the way to be quenched. During this transition further bending can occur, causing the bladesmith to spend valuable time reversing the warp and straightening blade after blade. The traditional long kiln design requires for deep tables or stands, taking up a ton of room in your workshop. With limited bench space, you may be forced to reach around a screaming hot kiln to reach tools, creating a potentially dangerous workspace.
Here's why the Jen-Ken Vertical Air Bath works so well... They've addressed the issue of uneven heating by designing the exciting new Vertical Air Bath furnace series. Their Vertical Air Bath furnaces deliver the best heat-treat possible because your blades are suspended vertically inside the chamber, allowing the blade to heat from all sides (360° heat), delivering completely uniform heat soaking at the desired temperature. The Vertical Air Bath is a refractory brick furnace with a specially designed baffle inside. Heat is absorbed into the brick of the kiln/furnace and is contained below the baffle when the lid opens. A unique cool touch handle extends out from the side and is reversable to either side of the kiln. When standing to the side of the kiln, the lid can be lifted without a blast of heat hitting the user. The blade can then be removed with tongs, and the lid is lowered. This quick motion allows for minimal heat loss and ease of use. The Vertical Air Bath chamber is heated from below the baffle and has another set of coils in the top section for quicker recovery as each piece is removed. The included power-interrupt lid switch de-energizes the oven, as you reach in to remove a blade. The Vertical Air Bath then begins heating again when the lid is closed. The kiln is designed to regain the full holding temperature, upon the users return from the quench. Blades never touch the kiln or each other, reducing the chance of heat sinks, cold spots, and warping. Spines remain straight because your knives are removed vertically, and then lowered vertically into the oil quench. This vertical suspension from the beginning of the process to the end allows for uniform absorption of heat and unimpeded movement while releasing internal stress.
Large capacity... The Vertical Air Bath chamber holds up to 12 blades of varying shapes comfortably. Blades can be suspended several ways. We recommend a pin through the tang, a spring clasped to the tang, or you can simply turn the tang sideways between the movable ceramic rods, if the tang shape permits. Foil wrapped blades can be suspended by passing the support pin through the foil sheet or via the spring clasp method. This allows the vertical suspension format to be used with every technique. The process has zero interference, leaving your blades stress free and straight.
Here's why you'll love it... The Vertical Air Bath is a smarter, safer, and more portable design, made to optimize your efforts, and make your workshop safer. The furnace comes with a rolling stand which allows you to move the Air Bath out of the way when it's not in use. Think of the bench space you'll save! You'll save time and effort due to the reduction of warps and waves in your knives. The power-interrupt lid switch prevents your blades from touching live elements, keeping you safer in the workshop. The Vertical Air Bath comes equipped with a standard 3-button controller that can loaded with the most popular normalizing, tempering, and heat treatment schedules. You can choose to upgrade to a 12-button controller for ease of programming, or choose the popular TAP smart touch screen controller. All of our kilns, ovens, and furnaces come equipped with standard mechanical relays, which you can choose to upgraded to solid state technology.
