My indispensible tool (a variation on a FB theme)

Actually, You can use an IT to build an oven with those diminsions in some cases. It would take an IT that is19" long. And then, setting the pivot point 1" below the finished floor height. That would mean taking 2 or 3 fire brick out of the center of the oven until the dome was complete. I think JR did something like this to compenate for the difference in his IT. Most pivots have an offset a fraction of an inch one way or the other depending on what the pivot is fashioned from. You would also have to take that offset in to consideration.

The IT is used to help build a perfect sphere. If you're using a height of 18, you're not going to be able to use an IT.

Hi master's , if building an oven with width of 38inch wide and a height of 18 what woukd be the actual arm or length of thIT TOOL? hope you could
help menoit on this. Thanks

Keep asking Jim, someone will have one available that they're no longer using. I got mine from someone on here, and passed it along once I was finished.

Hey Jim,

I am new to the forum. I am about to embark on a pizza oven in my back yard and have no skill set constructing anything. I've done the research and the only thing that worries me is the dome. Your tool seems to make the most sense to me. Do you have an indispensable tool I could take off your hands for a price? Thank you.

Hi Jim,

Long time reader, first post.

Any chance you are still able to make one of those tools? Like you were I am making an oven with little to skills. The only thing that intimidates me is the dome (and cutting bricks). No worries if you can't.

Really cool modification!

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

As my IT was mounted on a board and the hinge axis was higher again it meant without shortening the IT that the dome would end up higher than the radius by about 50mm ( whether this is of any real concern is conjectural). The problem with just shortening the length of the IT is that you get a lip as the face angle needs to change to keep the brick faces aligned. I also found that with the 1/3 bricks used on the higher courses that my brick bracket was too wide and got in the way, so a solution was found. Had a small offcut of some angle iron I used for the gantry under the oven, and tack welded it on to the brick bracket. Worked a treat and over the last 3-4 courses lowered the dome height back to the radius.

It speaks volumes that this thread was started in 2007 and yet your tool is still so popular! Congrats on a great design!

Does anyone have an Indispensable Tool they can dispense? I have a gent in need and am no longer able to make these for distribution.
Thanks,

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

Thanks for the reply so the dome is exactly 1/2 circle from cooking floor to top of ceiling correct?

That is correct, for a pompeii oven .

I did one turn on every layer.

No adjustments are necessary, for a true pomeii ( a perfect half sphere) .
