Third generation Masterly Tail oven design (3G MTo) building workshop.
There isn’t need for any hurry as building oven is a worthy project for the future, practical and pleasing in so many aspect. Still some people prefer to build oven or ovens faster to start cooking sooner. They play with decorations later.
For this purpose we built one out of cement blocks. No need to apply mortar between these blocks. Just stack them dry fit then fill with concrete (same as on some water dams – it’s stronger as well as quick.)
This is a base structure with the MTo insides. From here modifications can be adapted to most client configurations and needs (e.g. different roof kind or no roof at all, low set positioning in split level grounds, etc.)
Before I built this oven I thought about it for a while. I wanted to incorporate in it things that people desired:
- Heavy usage (in business for instance).
- Cold climate firing and efficiency (new double skin hood box/flue and the top hearth slab with its insulation under the slab).
- To create structurally a very compact design, not only for small backyards, just beautifully compact. It is still THE oven (it took me 1 year of testing and calculating so all fits in precisely).
- For the design to be also very easily adjustable in size (just by adding in or taking off a brick or two from a side).
- Building should not require too much measuring going around (mark lines on the concrete slab – raise walls upwards according the initial brick/block count).
- All brick, firebricks and cement block off-cut pieces as they come are returned into the structure (meaning overall less cutting, much faster and easier work, plus less material used).
- I’ve been asked on and on for how to lower costs. I share how we do this all the time.
- To be able to fit inside any firebrick part shape; barrel, rectangle or square kind, spherical igloo or avocado BUT also prefabricated domes or dome kits.
- And of course, as with all of my designs, this one is also suitable for indoors. With the modifications of course. The exhaust vent is calculated correctly, 100% of all fumes go directly upwards into the hot air passage. Resulting in carbon-less front deco facing wall.
* Before the building, reading this page might help heaps: saving money and time.
By all means, instead of concrete blocks, all the non-refractory parts on this oven can be built out of other materials. Ordinary house bricks (look at the the original MTo design if you have the disk, it’s crafted out of house bricks). Feel free to replace the blocks for bricks and create some art with them.
You can choose to use natural stones collected free outside in the nature (the natural or lime wash finish give a real great character to the oven.) Just remember to notice the size of the largest rocks you get; to add the possible difference to the ground slab – on each side. After that, all insides and general principles remain the same, except for the new material kind.
In her original fullness (I’m talking about the photographic sequence), without an angle detail missed, the whole oven building sequence contains 2783 large photographs – images #0001 to #2783
Enjoy it and then send us your oven photos when cooking.
