Good one. A few tips for anyone building this: Ceramic fiber plates (or the calcium silicate boards used here) can be screwed together with some inconel or stainless steel screws, adds strength to the build. I also find easier to use rivets instead of welding. Otherwise super job! I really liked the hinge and door knob, kudos

There is so much to enjoy in this video. 1. I really miss air travel, even if there is a baby crying. I have learned that traveling with foam ear plugs helps me block out engine and human noise. 2. I appreciate your sheet metal working. I have found that there is precious little of that on KZbin and my skills are lacking in that department. 3. Thank you for showing the site where you can calculate the coil information online. That saves so much time from looking the information up in a book and then having to do the calculations. 4. When you threw the popcorn in the oven, I thought about how bad that was going to stink up your shop area and more. 5. Loved the needle drop when you added the pineapple to the pizza. I wonder how many people will be "triggered" by that. 6. Last but not least, I laughed out loud when you said that the proper way to eat pizza was with a knife and fork. That was a great way to end this episode. Thanks for all of your incredible content that you share with us. Best wishes to you and your loved ones.

As a mortar/glue stuff could try sodium silicate also called waterglass. It's easy & cheap to make using lye and silica gel. I use it as a binder with perlite to cast high-temp insulating parts. In your oven case I'd replace the calcium silicate altogether with vermiculite in the inner side and perlite on the outer by casting the boards using the sodium silicate as the binder.

@@RotarySMP some tricks about that: you can cheaply make sodium silicate at the desired strength from silica gel in form of finely ground cheap kitty litter (the silica kind, not the bentonite or wood chip ones), lye and water. As a start, 250g-300g SiO2, 200g NaOH dissolved slowly in 500ml boiling distilled water will give you a medium strength, viscous silicate. You can mix that at 5% per volume with finely ground perlite or vermiculite to cast any shape you want. The kitty litter, perlite & vermiculite can easily be ground down to the point needed by putting them into a plastic bag & invite some friends to dance on it for a while. To harden, the silicate needs CO2 which can easily added to the mix by adding some baking soda and curing the cast at above 80 C so that the mixed in baking soda releases the CO2 right in the part where it's actually needed.

@RotarySMP I really like the swivel controls, but you have me worried about refractory cement. I began to pull the components together for a sizable oven, 14"x14"x22" tall interior... and then realized that in Canada there is almost no place to buy ceramic fiber board or blanket. In the end, all of it was bought thru Amazon. Prices made no sense at all. The cost for this rather roomy burn out furnace grew in leaps. So far I have almost $800.00 CAD in insul board and blanket alone. All the rest of the parts were easy to afford. I remind myself that there is no alternative. Turnkey kiln prices make my outlay quite reasonable.

Fascinating, thanks. I did think of building one myself but while browsing for suppliers, found a commercial HT oven that ticked the boxes I needed. Only thing missing was Argon purge but I will remedy that if the effort is worth the reward. I started Life as a Toolmaker at 16 from school, spent 20yrs or so in the industry before finding warmer (in the winter) jobs. Now, almost 50yrs later, I discovered that I still carry a candle for Toolmaking and it has become a serious hobby now and since I'm as good as retired, I decided to build a surface grinder from from raw materials (which will eventually be serialised and uploaded to my YT channel). When I spotted the EU sockets and you said you have 3-Phase, I half guessed you were in Germany (the boarding speech convinced me). I'm a Brit from N. Wales but have lived in Dresden now (where my Gt. Grandmother was actually born) for 21yrs. Went to subscribe to you and found that I already am, then another bell rang: are you the guy who helped ToT out with his Maho wiring? Absolutely gorgeous Country NZ, promised my Youngest Daughter I'll take her to explore the North Island one day too before we both get too old (and she settles down).

Sodium silicate (waterglass) will harden the surface of the board and can be mixed with fibres from crushed board to form an adhesive (it is used commercially - I think with a little latex adhesive to keep things together until the waterglass is fired). High temperature insulating bricks are available in the UK - e.g. shop.vitcas.com/insulating-fire-bricks-vitcas-grade-23.html (They also have a German website). I'd give up on trying to put a thin coating of mortar on top of the board - it's always going to fall off.

poly(methyl methacrylate) is just acrylic/plexiglas. It's also used as surgical cement for orthopedic work, like keeping hip implants in place. It came about because, surprisingly, WW2 pilots did not have terrible reactions to acrylic shards. These splinters of plastic were the inevitable result of being shot at in a plane with acrylic windows. At least, that's how I heard it. Thought it would be interesting because of your connection to the aviation industry.

Great idea about that calcium silicate. I've been struggling to find anything suitable myself. I was almost gone ahead with chamotte bricks and ytong bricks outside for insulation, but that would be hell of a thermal mass. About sealing the inside. It behives just like ytong, what I made my melting furnace out of. I coated the inside with about 12mm thick layer of chamotte mortar. Sieved the coarsest bits out. (Probably above 1mm) Literally dunked the bricks under water for 5 minutes to get it to stick, behaved just like yours otherwise. But after that it sort of stuck, and its strong enough on its own not to fall off if loose. Oh, and before I fired it the first time I was sure it was going to be a fail, but firing the mortar really helped. Stick me a message if you want more info on the experiments :)

I finally worked out that the correct german search is "feurleichtstein" There are some good offers for them cheap in ebay.kleinanzeigen.

I didn't think your cross bend looked crappy. If anything that little bit of an outward bend may save your firebrick from being broken There is a type of foam you can buy that acts as a heat conductor and is commonly used in consumer electronics, but does have pretty good thermal resistance. I imagine they have some for electronics which would be near a hot oven. You can also get thermal insulating foam which is good to prevent heat from flowing things you touch or things sensitive to electronics. I do not know how hot things will get but it works well

Hey, thanks for the video. How did the calcium silicate hold up? I had a couple of boards (Silca) I intended to use for just this kind of oven. But then one day... I made a trough out of them to contain a wood fire. They became really fragile after that, I wonder if they can stand up to bronze melting temperatures, like 1000-1100 deg. C. Some stainless steels need that range too. How is you oven after some use? Those boards aren't expensive either and very convenient to work with, but only specified to 1000 deg C. Soft fire bricks - 1500+ which is plenty, but way less convenient due to small size.

Installing a PID controller for a kiln is not hard to do. However, there are some assumptions about the thermoelement that can convert the whole installation into a nightmare. The thermoelement is actually made from two parts. The thermoelement itself and then the extension wire. Some thermoelements have the extension wire permanently attached to the thermoelement and some are separate. Care MUST be taken to connect everything the right way. Another thing about these is that the controller is actually measuring the temperature difference between the kiln and the connecting terminals of the thermocouple in the controller itself. Then there is an additional thermometer that is inbuilt in the controller which is measuring the absolute temperature. Now, this additional thermometer has a maximum operational temperature which is surprisingly low. The controller that I installed on my kiln has it's max operating temperature at 60 degtrees Celsius which is easily exceeded if the controller has a thermal connection with the kiln.
