I am drastically changing around the shop and need to find a kiln a new home. This is a newly built kiln. The rule of thumb is an inch of wood per year for drying wood at room air. By using these kilns, that is reduced roughly to an inch of wood per month. I dry roughed out bowls in a month or peppermill cylinders in 2-3 months. I gave a demonstration on drying wood and the use of kilns a few years ago for the club. Here is a picture of the newly built kiln and one of my kilns filled with bowls.
This is kiln is newly built, it's in excellent shape and has adjustable shelves. It's an upright freezer that is the same size as a full size fridge. I'm including a light fixture and a box of 40W, 60W, and 75W bulbs. I can deliver it in the La Crosse area. I'm asking $75. I'll also include at least 10 roughed out bowls to get you started. I've done the hard work and the refrigerant was removed by a professional.
I've used this style of kiln for years. They're made out of an upright freezer. There is a grid of holes in the top and bottom as well as a light fixture with a variety of bulbs. There are two methods of using this kiln; "batch" and "top to bottom." "Batch" means the kiln is filled and ran as a batch. Once the kiln is filled, a 40 watt bulb is placed in the fixture. This bulb is used for roughly 10 days or the first 1/3 of drying duration. Then the 40W is swapped out for a 60W bulb and that is used for 1/3 of the duration. At the end of that time, the bulb is swapped out for the 75W bulb and that is used to finish out the time. At the end, turn off the bulb and let the kiln cool for a day. The kiln should never go past 90-95 degrees. "Top to Bottom" means the kiln is ran at a constant level and the roughed out wood is moved from the top shelf down to the next shelf roughly each week to 10 days and so on. As the pieces get closer to the bulb, the heat is increased. It may require some fine tuning of the method depending on your individual needs. The kiln works by the bulb warming the air and pushing it out of the holes in the as it pulls area from the bottom holes. It's a warm, constant air flow. These kilns need to be in an area that is thermostat controlled. An unheated or uncooled garage doesn't work since the surrounding temps change too much. Sudden changes, causes wood to crack. Mine are in the basement. Any questions, please feel free to ask. "greg.haugen at ymail.com"
