This oven was built in October 2014 at the Occidental Arts & Ecology Center.  The OAEC has inspired many through its courses and example over the last three decades.  It was an honor to be invited to build this oven which is well situated next to their newly remodeled kitchen facility.

The deck of this oven is 36″ x 40 1/2″ deep.  It features a firebrick core with a vault and steel harness.  High-temp insulation surrounds the entire core, optimizing the oven’s efficiency.  The facing is classic looking recycled red brick with two wood storage arches facing the front and back and keystone for accent.

A highlight of the build was getting to help the community to experience their new oven by throwing it’s inaugural pizza event.  We easily fed 75 people.  The oven’s mass-to-insulation ratio is designed to make it efficient but not overwhelming.  We made a fire for three hours before starting our pizza session at about 750 degrees.  We made roughly 60 pizzas over the following two hours with a live fire in the back.  One nice thing about breaking into these bigger oven sizes is the ease of management of the fire and pizzas.  There is not the risk of getting pizzas too close to the fire or mixed up with ash, and it is easy to have 2 to 4 good sized pizzas going simultaneously.

The next morning at 9 am, I opened the insulated oven door and read an average temperature of 425 degrees.  Without lighting another fire, we cooked 12 loaves of bread… and then followed that up with 2 hotel pans of beans…. and after that whole winter squash and many pounds of potatoes.  At the end of that following day, the oven was still at close to 300 degrees.

Thanks to Alex Chernov of Stovemaster and Marcus Flynn of Pyromasse for being continual sources of inspiration as well as lending design and technical advice on this build.  And thanks to the entire OAEC community for making this project a big life highlight!

“Hey Max! Just a quick note to tell you that we have been using the oven lots, and loving it so much! The oven works perfectly. It is all we dreamed of. We feel you in every brick, and every slice! Thank you Max!

We’ll send some party pictures too. If you need any promo photos or testimonials, let us know – we are your biggest fans! Please come visit when you can.”
-Dave Henson, OAEC Excecutive Director

Lodge Style Masonry Heater

IMG_0774

IMG_0779

The clients really wanted the performance of a masonry heater but they also wanted their heater to be reminiscent of a lodge style open fireplace.  It would have been easy to build the core vertically and then just made the masonry thicker at the bottom but this would have made the heater less responsive and less even in its heating. We designed and built the core with a taper so that the facing could be a consistent thickness and then a local mason named Evan Grainger did the fabulous stone work you see on the outside of this heater.

Smoke Path

Like in many masonry heaters…. when the bipass damper is open, the smoke goes pretty much straight up.  When it is closed, however, the heated gases fill the cavities and then find their way up internal chimneys into another bell above the bipass damper and then find their way into the chimney.

Here are some photos of the firebrick core.  The design is a modification of the 5-run system so that the sides are actually tapered bells.  Firebrick and ceramic kiln shelf construction.

Big Bear Camp Barrel Oven

We were very happy to get hired by our neighbors Hal and Tonia of Big Bear Camp to lead a workshop to build a Barrel Oven.  We took the opportunity to make our first glass door for the Barrel Oven Kit and are thrilled by the result.  We think it speaks for itself….

In its last year of existence, the oven has already cooked food for a number of monthly neighborhood pizza parties, been part of the October menu for the Epicurean Bears Club, as well as helped prepare the feast for a pre-Thanksgiving get-together. We love seeing the glow of the fire as the food is cooking. Hal and Tonia report that they often just sit with the oven and a cup of tea as it is pre-heating. Stay tuned for a post about the neighborhood kids and their Big Bear Camp Barrel Oven baked gingerbread houses!

Blacksmithed Shelf Brackets

shelf-brackets-web I am excited about these recent results from the metal shop.  I’d like to make more of these for this holiday season and have them both in stock and as something of value that I can take to fairs, exchanges, etc.  Shelf brackets are a great way to mount shelves and so many of the options available at the hardware store are not as solid as you would like them to be.

The Ultimate Laundry Drying Rack

In our quest to live smartly and well, Eva and I have resisted the urge to use an electric dryer to dry our clothes. Although this common appliance certainly offers some conveniences, it seems a gratuitous use of electricity and energy that is otherwise available to us in free and smart ways. We had been getting along alright hanging our clothes out in the sun during the warmer months and hanging them on expandable accordian-style wooden racks near our heating stove in the colder portion of the year. With the arrival of our new-born daughter and the prospect of many loads of cloth diapers to wash and dry, I figured it was time to up the anti and improve our system or else succumb to the need for an electric dryer. I wanted to build a drying rack that was retractable to the ceiling so that it wouldn’t take up any floor space. This turns out to give it the added benefit of placing it up in the warmest part of the house and exposes all the clothes equally to this rising, circulating hot air.

Watch the video to see more details about how it works.

Masonry Heater in Bend, OR

allen-heater

Masonry heaters are a relatively new tradition in North America. We do not have the same tactile memory that many Europeans do of experiencing the warm, thorough heat. As such, many of us builders spend a lot of time educating potential clients. This was not the case with the Allens!

This was their fourth masonry heater in as many homes! They knew exactly what they wanted and knew all of the benefits of living with a masonry heater from their many years of experience with them. Their first heater was a “Russian” heater and their second two were built from Tempcast kits. Although satisfied with the Tempcasts they had, they hired us because they were interested in the Masonry Heater Association’s 5-run design due to its compact footprint and top-venting chimney.

Process….
