Paragon Double Barrel Heat Treating Furnace W11"xD18"xH4.25"
|Long lasting solid state relay
The Double Barrel KM18 now has a solid state relay, which lasts far longer than a standard mechanical relay. The solid state relay has no moving parts to wear out. The first thing you will notice is that the solid-state relay is silent. You will hear just the reassuring hum of elements. The solid state relay makes heating elements last longer and offers better temperature control during holds.
The Double Barrel KM18 includes a mechanical relay as part of a safety circuit.
The Paragon Double Barrel KM18 is just the right size for heat treating and case hardening gun parts and knives. It is especially popular for pocket knives. Experiment with color base hardening. Restore the faded colors of historic guns. As with the other Paragon furnaces, the Double Barrel KM18 has a digital controller so you can program the exact temperature and hold time needed.
The controller eliminates guesswork. Instead of estimating a temperature by the color of the heat, just program a temperature. You will no longer have to adjust a switch to maintain the hold time for case hardening; the controller maintains the hold time for you. Set the hold time for as long as necessary (typically two hours).Choose a side swing door or a drop door
You can order a Paragon Double Barrel KM18 heat-treating furnace with either a drop door or a side-swing door. (The photo above shows the traditional drop door. also available with a side swing door.) The price of the furnace is the same with either door style.
The drop door opens downward with one-handed operation. A counterweight handle holds the door securely closed. The door, whether drop or side-swing, is mounted on a heavy-duty 1/2” thick hinge shaft for smooth opening. Because of the rigid case and heavy hinge, the door is sturdy enough for years of faithful service.Door safety switch
The door micro safety switch shuts off the power to the elements when the door is opened, yet the controller continues to give a temperature readout.Superior heat distribution
To improve the heat distribution in the Double Barrel KM18, we have added heating elements in the top and removed the heat from the back. The furnace now heats from three directions--the two sidewalls and the top for uniform heating.The Sentinel Smart Touch temperature controller
This unit will be the next generation of kiln controllers with its modern and intuitive user platform. But, because results are what counts, this one also includes the knowledge that is at the heart of every Bartlett controller. We design, manufacture and sell all of our controllers with our customers at the forefront of that process and we insist on procedures and systems to continue to be a reliable and consistent resource for artists. The control strategies that have produced so many successful firings with Bartlett controllers will only be enhanced by this new format of display and user interface.
This controller will make firing kilns just a little bit easier in these ways:
The furnace is insulated with 3” thick refractory firebrick, which is 1/2” thicker than the standard. The sidewall elements are mounted in dropped, recessed grooves machined into the firebrick. This groove protects the element for long life and low maintenance. The elements in the top are seated in pinless element grooves. The firing chamber is protected by a rigid steel case. A built-in solid stand lifts the firing chamber safely off your worktable. The thermocouple wire is kept inside the case for protection from the harsh environment of the typical bladesmith shop.Printed instruction manuals
Your furnace includes a wiring diagram, a controller instruction manual, and a heat treating manual with heat treating instructions for D2, 440C, ATS 34 and 154 CM. The manuals are written in plain English for the beginner.Made in America
All Paragon furnaces are made in Mesquite, Texas USA. We are proud to support the American worker.Optional Gas Injection Flow Meter
During heat treating, scale forms on the surface of the steel. One way to eliminate most scaling is to wrap the steel in stainless steel foil. Another way is to install the gas injection flow meter on your furnace. It is available as either an add-on kit or you can order the furnace with the meter installed.
The meter regulates the flow of an inert gas, such as argon, inside the furnace. The gas displaces the oxygen to prevent most scaling.
Please remember that results with the flow meter vary depending on the type of inert gas you use and your level of experience. For more details, click on the link in the Options section below.A message from Ed Fowler—explorer, author, and founder of High Endurance Performance Knife Association
“Paragon offered me no financial rewards or free equipment for this endorsement. I recommend Paragon furnaces only because they make an excellent, reliable product.
“I've made knives off and on since the sixth grade. I enjoy every second in the shop making knives. I used to harden and temper with a torch. As my skills increased, my testing of knives revealed the benefit of longer and more uniform soak times during the annealing and tempering cycles than were possible with a torch.
“I finally bought a Paragon furnace. It is extremely beneficial to bladesmithing because it allows us to do things with our blades we couldn't do otherwise. If I had known how good they are, I would have bought one, years before I did.
“You don't want to introduce any variables into your blades by accident, and the temperature is one such variable. With a Paragon, you know exactly what causes what and why. My advice to beginning knifemakers is to use the best equipment you can as soon as you can add it to your shop. I wasted a lot of time and energy trying to make knives with less than the best equipment for the job. Invest in quality equipment, learn how to use it right, and use your time seeking the best knife you can make.
“Without my Paragon oven, I would have never made the discoveries about steel that I’ve made. I love my Paragon. That Paragon sure made a big difference in my knife making. Any experiment I want to run is right there. If I want to change a heat treatment, I know exactly how. With every knife, I learn more.
“Thermal cycles, commonly known as heat treating of blades, are the most significant single aspect contributing to the quality of a knifemaker’s blade. Knifemakers who wish to explore the absolute frontiers of the world of knives in search of the Excalibur of their dreams must have the ability to design thermal treatments specifically intended to push their steel to the highest limits of performance. Absolute control of the temperature of their blades is absolutely essential to success.
“Paragon makes a nice piece of equipment. I recommend it very highly to anyone who asks and to many people who don't ask. In order to make knives that my customers can depend upon, I have to be able to count on my equipment to provide consistent performance. My Paragon heat treating oven has always provided the degree of dependability I can count on to support my commitment to provide my customers the best functional knife possible.
“Believe me, I'm much richer knowing I'm making the best knife I can. I'm much happier with myself.”
