That's nice Dave. I like it much better with both the windows on the front. I look forward to seeing more info on it  |

Dave, Thanks for sharing. That's a really interesting build. Let us know how it works out for you. For future reference, if you grind down the edges of the angle steel before you weld them, so a cross section of the two ends are like this \/ then you can weld into the top of the V and grind it level so you don't have to see the welds |

Looks awesome Dave! I love the window placement. I've had a couple builders say to me that they liked the stove but wanted more fire watching. I always felt like they could use more imagination as the possibilities with this stove are endless, and offer better fire view than any design I've seen. Thank you for your vision and for sharing.

Dave the sound is dodgy on this computer : did you explain the large 'glass' front panel?
Is it ceramic glass, one piece or two pieces?

I too like the 'fire place' feel of this, however that's a lot of glass in the primary chamber area. I would guess that you will loose a lot of heat in your primary burn chamber to the ambient temps beyond the glass.
It's a great design, I like the double bell and the ability to adjust the exit ports. Question about that: Did you calculate for the exit openings being large enough in all configurations? Left open, Right open, Middle setting both the same?

Very nice dave!
Has anyone thought about trying to make an insulated glass unit for something like this? Would add some insulative properties to the window in the riser without taking away from the view. In the fenestration industry, they use a metallic(stainless alloy) spacer system from coil stock that is rollformed and stuck between two pieces of glass with a "Butyl matrix" adhesive. This creates the insulative gas chamber that can be evacuated for an inert gas (argon or krypton) before sealed entirely. This could be done with any glass really, not sure if the butyl matrix would handle the heat, but if the edges of the glass are far enough away from the direct heat blast, might be fine.

All-glass stove would be something to witness!!

Hah that would be neat, but the insulative properties of glass are horrible in the grand scheme. Also finding an adhesive that could handle the raw temps would be difficult.
It wouldn't be the same as a proper IGU, but for the DIY group I think if you had a second piece of glass you could possibly increase the insulative value a bit of the window by using some of the ceramic rope or so to make an ad hoc IGU with a second pane. You would want at minimum a 3/4 inch gap between the panes, 1 inch would be best.

A sealed unit wouldn't work, even if you could find a butyl like material that would take the heat, the expansion of the gas inside would cause it to explode.
An unsealed unit could work. A steel bar wrapped in the sticky-back fiberglass tape as the spacer, then the 2 pieces of stove glass held together around it with the really wide sticky-back fiberglass tape, should work OK.
Stove glass in the flame path of a rocket stove gets a coating of find ash bonded to it after a few burns, it makes it look frosted. Comes off easy with a wet tissue or baby-wipe though, but means you have to be able to get to the back of it to clean it off, so you'd want to make it easy to access.
