Are you sharing dimensions as you did the old stove? Tia. Fig. Sure, just ask if there's any others you want: Firebox is the same size: 12" wide X 12" high X 16" deep. Port is: 2" wide X 6-7/8" long. Top chamber is: 9" wide X 4.5" high. Exit from top chamber adjustable between: 2" to 3" X 9" (to tune the core to your mass). Must have a bypass damper for startup. |

Thanks Brian. I vaguely remember your thread, it was this one wasn't it? donkey32.proboards.com/thread/1690/walker-core-variation Unfortunately all the video links are broken, which is a real shame. My stove is a lot shorter and wider than Peters DSR. The firebox is only 15" deep by 12" high and wide. How much space do you have for yours? The firebox would be fine with the door on the side, but a window on the side of the afterburner would be looking at the double vortex side on, so you'd lose that beautiful end on view of the rams horn. Over the winter I've been trying out a lot of different little tweaks to the afterburner and port, looking for anything that helps keep the vortex spinning in the back of the chamber longer. Most either were a hindrance or at best didn't do anything. The 45 degree bits in the bottom corners helped of course. The other one that does seem to help quite noticeably is this little bit on the inside front edge of the port. I call it the port bow, as it's like the bow of a ship. Yes, that's the thread. I went back and checked, and I still see all the links that I posted... scared me there for a sec! Not sure why they wouldn't be showing up for you. They're hosted on Google plus, and you mentioned an issue with viewing those at some point, maybe it's still the same issue. I don't remember the exact measurement of the space I have, but it is perfect for a PBB in horizontal configuration, sans riser on the end. I have a bit of extra depth to play with since his firebox is narrow, so the test I want to do is to have the slot face away from the stove glass, then have it do a 180* and come back toward the front of the stove again before turning 90* right to enter the bench. That way I get to keep the double ram's horn, but watch it go away from me, then watch any leftover flame come back at me again. I'll try to get that new thread going once the new year is here, I'm full up on family obligations at the moment, but chafing to get going on this. As one of the earlier videos in my post showed, though, the side view of the double vortex is quite captivating in its own way as well, so if it came down to it, I'd still find that a great fire viewing element. I am hoping that having the flame path flow away from the glass might help keep it cleaner for longer, but I do want to have it be configured as a door to make cleaning quick and easy. Watching your second build develop, I really like the metal frame with dry-stacked innards as an approach to building. I don't have any metal-working skills, but the flexibility that this introduces is something I regard as invaluable. It's a fantastic way to preserve the ability to go in later and adjust the flame path or swap out over-chafed firebrick. Your "ship's bow" vortex inducer is an interesting idea. I've at various times played with putting a port-width obstruction across the flame path so that gases can never simply slide out of the slot and directly downstream. It made less of a difference than I had hoped, since a vortex requires a certain amount of velocity of gas flow in order to start up. I don't see that I documented that anywhere in that thread you referenced, but it might be something to toy with if you are still playing with the idea of trying things that sustain the vortex longer. The down side, of course, is that the obstruction (bit of brick, or whatever) is always there, and may be something that you don't necessarily find the most visually appealing. |

I wonder what's happening to G+ links after the consumer edition is shut down in a few months time. Is everything going to be lost?

Uh oh, I hadn't heard of an impending shutdown. Will have to look into that. I don't like the idea of losing all the time I put into that thread! There is probably some way to archive a website, I would guess...

Yes, that's the thread. I went back and checked, and I still see all the links that I posted... scared me there for a sec! Not sure why they wouldn't be showing up for you. They're hosted on Google plus, and you mentioned an issue with viewing those at some point, maybe it's still the same issue. This morning I tried it from 3 different browsers, from my ISP and via a VPN, with and without the antivirus program running. Every way I got: "404. That’s an error. The requested URL was not found on this server. That’s all we know." Then I had to call into see my neighbor so I tried it on his machine and it worked! I eventually tracked it down to not being logged into a google account, which IIRC was the original problem I had on your thread. I thought you'd set it to public so that didn't happen any more? Sounds like an interesting build. Will you do some outdoor trials of the setup first? The only benefit of having the flame come towards the glass I can see is it quickly burns off any smoke residue from the startup phase, but the downside is it seems to gradually etch the surface of the glass and makes it slightly opaque. So will be interesting to see what difference that makes to yours. I had very little experience with metal work before I made the metal bits for my original stove, and all the parts of the new stove I made using a 4" hand grinder, battery drill and little DIY arc welder. I made a lot of mistakes but learned loads in the process. It's brilliant being able to take the stove apart reconfigure bits and have it quickly back together and running without covering the house in dust. I've tried putting pieces of steel in various positions, but so far haven't seen any noticeable benefit. I didn't want anything too large though that would block the view. My present thinking is to try a small step up in the base and sides of the top chamber about halfway down, only about 1/8" to 1/4", to add a bit of resistance to the gasses as they spiral outwards. Right, I'm off to re-watch all your old videos  . |

Ugh. Thanks, Graham. Any thoughts on a good service to move my stuff to? A service that allows one to embed pics and vids here gracefully, and hopefully a service that isn't in decline... Even if there ends up being a way to keep my links going, it seems that folks who aren't logged in to a Google account can't see my stuff, and I don't like that, so I should probably migrate anyway. |

Hey Vortex, is there a quick way that you quote someone and chop it into segments to reply to it? I like that idea, but I don't know how to do it other than copying and pasting bits of HTML when replying -- is that what you do?

Sure, when you click 'Quote to reply with the original text, you get something like this: [quote author="@livelsbe" source="/post/31569/thread" timestamp="1546355433"]Hey Vortex, is there a quick way that you quote someone and chop it into segments to reply to it?

Cool! I thought for some reason that I would have to re-type the entire "quote... author... source..." bit each time, glad it's simpler than that!

I eventually tracked it down to not being logged into a google account, which IIRC was the original problem I had on your thread. I thought you'd set it to public so that didn't happen any more? I went back and checked, and they are all set to "public, can be viewed by anyone, anywhere," so I'm not quite sure what else to do there. I think I might have to move all of my stuff anyway, though, since Google is sunsetting Google+, so I'll try to find a service that doesn't force people have an account and log in. what service do you use for pics / vids? Yes, I have yet to bring a build indoors, every iteration has been outdoors so far. Every time I think I'm getting close, there is some new development and I come up with new ideas to test. Then spring comes, other parts of life busy, and it gets side-tracked until the next season, and the cycle repeats . I have definitely noticed the soot accumulation during startup. I have toyed with the idea of adding an air wash as is generally done with stove door glass, which could possibly be the source of secondary air, now that I think about it, since for me my glass will be before the slot, not after it. But that is for a later phase when I get to working on doors. Also, my current plan, based in part on the space constraints, is to have a bypass that exits out of the back of the firebox itself, but I would also hope that it would minimize the initial afterburner window soot accumulation problem. I am also hoping that by having the vortex directed away from the glass it might stay cooler and minimize etching over time. Jeepers, a DIY welder? If that's doable, surely I can figure out how to operate a regular welder . Fingers crossed... Interesting thought, I'll keep an eye out for posts about developments! And I guess since we've had this much discussion about my next planned experiments, I should probably get that thread going. Here's a link -- having it in writing should help push me to make time to do the testing! |

I'm curious what is the max temp the calcium silicate board is rated for? Of the products I see available to me, they max out at 1700F/972C. I suppose that would be close for the firebox, not enough for the riser areas though. Hello Man, I’m a Chilean guy, and i would like to make my own stove kitchen, like yours because de design is so beatifull. I will appretiate if you can share with me more info about the proyect to help me about construction. Thanks Best regards Fabian |

Hi Trev, Been a long while since I hopped on the boards (been homeschooling, youth working, 5 or 6 heater and natural house builds at once... on the go 7 days a week for TOO long...) I'm just now catching up on the progress you and the gang have made. Looks like the V-port with ?? triple shoebox? is an improvement, especially as the deck of the middle/upper chambers can be tweaked at will.
Thanks so much for all the time and focus you have put into this research.
I'm just finishing off a huge masonry heater with a full size eco-box with bake oven. Glad to have done it, but looking forward to coming back to this simpler approach.
well being
pat
