Speaking of string...

I have another adaptation that I am contemplating prior to starting my oven. I would like to cut my bricks so that they fit as close as possible (within reason) to optimal shape. I believe attaching a string to the center of rotation (hub/hinge) of the Indispensible Tool (IT) will allow me to determine the exact angle of cut for each side of the brick by drawing the string taught to the far bottom (outside) corner of the brick and allow me to draw (snap if i use chalk on the string) a line from the inside edge to outside edge in perfect alignment with the true line of the previous chain.<P>
<P>
I also noticed that when a rectangular brick is clamped in the Indispensible Tool as a dry fit the interior edge of the brick is in contact with the lower chain at the inside of the oven. The back is elevated slightly, most people are building their ovens by filling that gap with mortar. If one would use the same snap string to just contact the interior edge of the previous chain and snap a chalk line along the brick being held by the Indispensible Tool a perfect angle for the bottom of the brick would be marked.<P>

Remember, that the abrasive wet stream from your saw will blast off most line materials, including pencil and certainly chalkline. You will have to line it up and cut by faith, or go over your line with a marker.

Your brick is 4.5" in that direction, you will need to make 2 passes unless you have a saw that will cut that deep. That is a lot of cutting for each brick, to gain what exactly?

Thanks for the great pictures with their added annotations & lines. One picture is really worth a 1k words.
When I built my oven this past fall I found a source for #1 Arch firebrick (in the Albany, NY area). I used those for all of my rings and only had to 'pad' the ring-to-ring joints a tiny bit on two rings, minimizing the amount of mortar required. I feel that I have an extremely strong dome. It supported my jumping up and down on the crown.

...Glad the neighbors didn't see or hear me grinning ear to ear shouting with glee while performing these gymnastics. Otherwise I would probably be on medications in a nice soothing place without access to matches, sharp objects but allowed visitors every other Friday...

Less dependence on mortar would be my guess. The more precise, the more the arch is doing the work instead of the mortar.

Mind you, I doubt the qualitative difference would show up before 10 -15 years at the earliest (excepting the entry arch which would show much more quickly).

Talking Re: My indispensible tool (a variation on a FB theme)

This is the site that I will be building my pizza oven on. I will be pouring a 5” pad on top of the existing concrete, because it has too much of a pitch. This is the tool that I built this morning, the turnbuckle is so I can lower the dome. Pictures below

Just the thought of seeing someone jumping up and down on their dome brings a wide smile to my mug, and just shows how truly nuts those of us that build these things are. We labor to design, assemble the components, build the dome, cure the completed structure and still feel the need to do EXTREME testing.... I would give good money to see that test on film.

Here is another tool, kinda like Huck's. Had some help and not ready to to use it yet, but became hooked on building one ever since i started reading the forums. My indispensible tool (a variation on a FB theme)-tool-1.jpg

Smile Re: My indispensible tool (a variation on a FB theme)

Your tool looks great it should work fine. I am in the process of poring my foundation. I hope to get started next week on the base
