Castable Oven – 3D Drawings/Models

[aaronpizza]

Hi all,
I’ve been speaking to a few of you and I’m going to start planning my 32inch Castable (homebrew).
I find all the information quite hard to understand myself.
So I’m going to do some 3D drawing (Autodesk Fusion 360) and make them all public here when I’m done.
I’d love lots of feedback on the design elements (size’s etc) - Sorry if my CAD drawing isn’t up to scratch :P
I’m also producing a detailed Excel sheet with all my dimensions and using formulas to calculate everything, which ill make public when I’m done too.
So if there are any good equations I should be using please let me know!

Some have mentioned a ~200mm (https://community.fornobravo.com/for...803#post413803 - DavidS ) Entry length is fine, keeping it very tight to the 150mm Flue.

Should the 200mm Start from the inner wall of the casted dome as per the drawing, or from the External Verm-create?

Another member has already done an Excel spreadsheet on calculating materials for a cast oven. Why reinvent the wheel.

Also, I notice there is not a reveal for the oven door to sit against on the CAD design.

To make the entry shallower I moved the base of the oven mouth 20mm inside the inner dome perimeter. My flue gallery depth is125mm against the oven mouth, an 8mm expansion gap and 70mm for outer decorative arch including tiling (total 203 mm) enables me to sit the oven on a square footprint of 910mm.
I've attached a pic which explains this better. Look closely for the pencil lines. There are many ways to skin a cat, this is just my solution.

ah didn't find this excel sheet! Certainly don't want to reinvent!

thanks this is useful! I, in fact, did my first drawing wrong in a few places so started again

Hi DavidS when you say a footprint of 910mm, what size oven does that apply to ?
Cheers
