@@bigdilliams ha ha I doubt that very much…

@@geordiem8496 Thanks, that is the only pizza oven that I actually bought, all the others were cast in my own mold but it was out of commission at the time of this build so I had to buy one. The oven was OK quality, it did not go together perfectly and it did crack in quite a few places, although nothing too bad or structurally worrying. The base has worn though, it has become quite powdery and always needs dusting off before use. My own cast ovens have faired much better, some are 15 years old and still not showing any cracks (probably not used much) unfortunately my mold has long gone and I dont build pizza ovens anymore. I did train as a boat builder but I have mainly worked on hard landscape projects most of my working life. I have not been back to see how that particular oven is holding up for some time but as I have not heard back from my customer I guess it is still running fine . I did not like the two piece base and would much prefer to use standard fire brick.

@@foxfish7115 Thanks for taking the time to reply. Yes, I did spot the floor cast is a bit coarse, powdery and friable. Quite odd. Thanks for the tip, I might swap it for firebrick as I have about 30 around. Cheers

Well sort of but as I am still working on the design it might be better to wait a little while until I can establish exactly what works best…. Please look at my latest videos.

Hi thanks for taking an interest, I have developed the stove since that video, you can find more recent videos on my channel.

Always experimenting…. Works both ways but the splitter does not last long !

The tube inside is caller ‘ riser’ it is very important to keep the temperature high so all the smoke and wood gasses are burnt. If you did not insulate the riser, there would be smoke coming out of the chimney.

@@foxfish7115 thanks very important then

Hi thanks for your interest, I have dozens of rockets stove videos many are based on experimenting and developing.

Thanks, still recovering but almost there! No not heard of recoheat, I will have to look it up….

Hi, thanks for your comment , the secondary air in this format is massively pre heated as it travels through the space above the fire box. The temperature inside the fire box runs around 500-550c, the ceramic glass that make the top of the fire box allows most of that heat into the secondary air gap so the air is very hot but you have to be aware of just how much pre heated air expands so the gap has to become bigger and bigger the hotter the air becomes. So in this case I think the secondary air will be around 3-350c when it enters the vortex chamber.

Hi and thanks, there is one video (lots on my channel) that has the dimensions but I am going to develop it a bit more this year…..

Thanks almost there now, I will be back soon…

The vortex stove does work well when it is n song but can be a bit fickle on occasions, a well built and insulated J tubes are extremely reelable ( plenty of example on my channel ) and might suit you need better.

Thank you for your kind reply. I'll be sure to subscribe and watch your videos on J tube stoves.@@foxfish7115

Thank you my cyber friend, I am having some really space age surgery to destroy a tumor on my right kidney but it involves going through my lung with a probe to freeze the thing! In theory I should only be in hospital for 3-4 days.

Blimey...Space age indeed...Wishing you well ...Glen@@foxfish7115

Well I have heard of people using salt and polystyrene (styrofoam) but nylon fibers are the tried and tested method. You can buy ‘counter top’ reinforcing fibers from many stores, they are extremely thin and wont effect the overall strength of the finished product. I think the little poly balls would be far too big for our purpose.

@@foxfish7115 well at first i thought using hair due to another video of someone trying to make clay, then thought about the styrofoam. Then i scrolled down after commenting and saw the comments using nylon rope. Lots of rope around my parts since its a fishing town. Great video, i appreciate you taking the time to respond to my comment.

@@rashadabdullah9769 yes you could try nylon rope although try to find really thin stands as possible, human head hair would be closer to counter top fiber thickness. I think a lot depends on the project and its use but we are looking at around 1% added to the mix. Make sure the fibers are evenly distributed in the dry mix before you add any water, it can be very frustrating and time consuming to get them spread out evenly but worth the effort. Good luck and please let me know how it goes …..

@@foxfish7115 i want to build a stove, on the ground. That is my intention. First i gotta build my home, but def will be dirt floor. This way the floor will be a heat sink. I also want to mould a large water tank where i can just throw buckets of snow to melt. Right now i am tied up with a project i started 2 years ago, a new (my third) bike trailer for my moped. Once thats built this spring and all goes well i will be saving and planning my next projects: chicken coop, or rabbit, summer home and winter home. Here in canada i hate how all homes are built with solely winter in mind.

@@rashadabdullah9769 you will need to isolate the fire box from the earth otherwise as you say it will become a heat sink and not allow the fire box to become hot enough to burn the smoke! Anywhere, where there is a flame, must be very well insulated. After the flame you can steal the heat but leave enough to power the chimney. Keep me informed when you start planing…..

Migjt be a bit heavy and awkward to move around but it is capable of heating large spaces!

@@foxfish7115 Yes that is right, but have seen batch boxes made from fermiculite board and wrapped outside in thin metal, bend a box where the heater is in. This are light versions suitable for this purpose. Thanks for reaction.

For a pizza oven there are two main options …. Four parts crushed fire brick and one part high temperature cement (cement fondu) or what is called ‘home brew’ one part portland cement, one part lime, one part fire clay four parts sand. Nylon fibers should be added at 1% in both mixes. Good luck.

Thank you very much@@foxfish7115 , any thoughts on the 4:1:1 ratio (4 parts Perlite, 1 part sharp sand, 1 part refractory cement)? I am planning to cast it in 6 pieces, so to allow for thermal expansion.

@@ariadnasol you do not want to add insulating material to a pizza oven, you want the opposite = dense mass to hold the heat. You can then cover the mass with insulation to hold the heat inside the dense mass. If you look right back on my channel there are a couple of pizza oven builds that I did .

@@foxfish7115 Thanks again, makes all the sense in the world. I will look into your other videos. Have a great day, and thanks again for your quick replies. Salud !

@@ariadnasol no problem just ask any questions….

Thank you for your comment. My rocket stove videos are largely about experimenting with different formats. That particular design with the off center riser and horizontal oven, has run for several years very successfully heating a large uninsulated space and supplying food for my friends. Personally I would call that a success ? However if you look at my latest rocket stove videos you can see the stove running without the oven, it shows no noticeable diffidence apart from not being able to cook fantastic food! The vortex J tube design works best (so far) with a short tunnel so with a 6” system the riser sits off center. Please look at my many other design rocket stove videos and thank you again for watching.

I would guess in depends on where in the world you live but I use west systems epoxy for glueing and nowadays I use international two pack varnish which is polyurethane based.

Thanks very much. By chance, I've just got off the phone with West System's UK reps - Wessex Resins. They were super helpful and even suggested an additional bonding layer for the laminates which involves applying a second coat that contains their 403 Filler. Will follow their advice and let you know how it goes on the Deeper Blue Forum. Many thanks again. 🙂

The main air supply is from the top of the fire box like any other J tube but I just adjust the amount the fire need buy sliding the glass back or forth but usually once the fire is hot it run with a one inch gap

Hi, yes of course, I have other videos showing how the stove can be connected to a barrel and some mass and also as a cooking hotplate. Thanks for watching, I just make the stoves and videos for fun.

Ha ha yes it went a bit crazy!

Thanks for watching, I will hopefully be back in action in the new year.

I make them for myself, not for re sale.

Sorry must of missed your post, yes exactly that, too much air cause a thermal overload when too much fuel is burning at one time and the fire will start smoking out the chimney.
