Speaking as a Canadian and a former professional pizza cook, pineapple on pizza is our greatest shame.

That intro had so much ToT-Vibes, like you're twins - still figuring out, who's the evil one ;)

Safety wire pliars!!! Salute to fellow aircraft mechanic!! I’m a retired C-17 Flying Crew Chief (flight mechanic) from US Air Force.

That crying child on the plane. That brings back memories. Not good ones, good work surviving with sanity intact.

Glad to see you back, thanks for sharing.

Fun having you travels in the vid, gives a good sense of time. Thanks, keep entertaining me KZfaq slave!

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

Pineapple yeah! Awesome build!

I literally have half the parts here and half the parts in mail and then you upload this :D Perfect timing!

Nicely made oven, interesting mix of music this time Greetings from Japan

That was fun to watch :-) Reminds me of my unbuilt oven, still in parts as I bought them about three years ago, and the will to build it just seems to fade, whenever I get close to them - must be some sort of black magic spell :-)

0:35 Ah, yes, the good old ice cream container. An all-time favorite of shops all around the world, along with a can of Heinz baked beans.

Damnit! I was just binging my way through the camera arm vids again, thinking “yeah it’s Sunday night (here in aus) so he should upload a new vid soon, but I need to go to bed soon, and he hasn’t yet, so sweet I’ll just watch this and then...... you upload 🤣 Keep the choice content coming bro, absolutely loving it.

Awesome build! I love the attention you give to aesthetics in your shop projects, giving them a professionally manufactured look. You and Mark Pressling need to have a Australia vs New Zealand shop project face off. LOL!

Welding shots with techno in the background were amazing. Love your style, please keep it up! Cheers!

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 KZfaq 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.

I was thinking “Wow, very cool!” until the pineapple. Now It’s full on Awesome!!!

Excited to see this, can’t wait to see the next casting attempt after a solid burnout, with a hot flask when you pour!

I just love it! Great oven, great pizza. Every time I watch one of your videos I realize how much alike we are. Canadian bacon and pineapple pizza is the Friday night special at our house. For my roomie, I make his half of the pizza a traditional pepperoni with mushrooms, onion, olives, and anything else I can find lying around the kitchen. On my half of the pizza, I put chopped onion, mushrooms, Canadian bacon, and lots of pineapple bits then top the whole thing with handfuls of mozzarella cheese. I usually spend the rest of the night binging on KZfaqs and eating pizza. Ahhh, the retired life. I'll be making my furnace later this summer. Thanks again for the inspiration.

Great channel! The vinegear trick is fantastic. BTW 25:00 - TCs are not resistive elements. They're creating voltage, in microvolts, so it can be amplified, measured and converted to temperature readings. Keep posting vids. You have a really valuable channel! Thanks:)

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). Gonna watch more of your offering now (sorry I didn't when ToT mentioned you - but I've been busy myself). Thanks...

Fire resistant rope, as used on woodburning stove doors for your door sealing issue, I'd say. and as I type that, I see it's exactly what you did.

I appreciate the bangin' techno

Ohh boy, did I enjoy this part! XD Absolute coolness!

Really like the look of the controller with the massive heatsink. Looks really cool.

This hits close to home, since I'm making 1.8x1x1m powder coat oven right now (about 60% finished) and later would need heat-treat oven for loosening hardened edges of plasma cut parts for drilling. Nice project. Cheers!

Enjoyed the video and also enjoying the suggestions in the comments. I would eat the pizza but I'm a folder. No forks involved. Hope the oven proves useful!

Great music in this episode. Also fun build.

Reminds me how we once tried to cook/grill sausages in the heat treat oven at wort (ofc we ended up burning them )

Always out of this world. Incredibly nice result given all the compromises. Sorry I have no recommendations for a heat resistant hard coat. Great to see you again..... 👍👍😎👍👍

30:20 Things you don't want to hear an aviation engineer say XD

Maybe add a small argon inlet so you don't oxidize your pizza when case hardening it.

Great looking pizza thingy wotsit oven. If you use vertical then add argon at a low flow through the door you might get good unoxidized parts. Seal up the sides and bottom really well so heavy Argon can't escape. Just a thought. Great build. Good to see you back.

Uh, new Pizza oven.. good for you ! :) Nice build btw, thanks for sharing !

Just found your channel and gotta say it’s great stuff! Keep up the wonderful content!

Nice build, gives one food for thought. Cheers Bengt

Those heat sink spikes might be totally unnecessary for the thermal dissipation but they are 100% vital for the aesthetics. Although, you'll probably find a sharp spot next time you go to swivel it round...

Nice build, great addition to the shop, if I may suggest when welding angle iron, leave a few mm gap in each joint, less grinding for a flush mount. I have a similar box with heat treat oven components, to upgrade a simple element type. Thanks for sharing.

Great work and a lovely drill press u have

Excellent project, well done, thanks.

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.

What I did was make the interior out of firebrick, surrounded by silica board, surrounded by rock wool, with a sheet metal exterior. I didn't use a hinged door, but a drop down sliding door.

Nice musik in this video! Love this style of video more then usual ones.

Vienna airport, long time no see! Very cool build and a pleasure to watch. Thanks!

4:03 yeeeees my favourite sound effect... particularly on 10+ hours transcontinental flights :) You plan to sleep a little on the plane and then it is enough 1 of these little bastards, and it doesn't matter how far you try to sit away from the noise source, it will be strong enough to hear it anywhere :)

The world's first airplane mechanic CNC machine builder/operator vlogger.

Thats a stylish drill press, very nice unit. Looks a bit like a cake mixer for industrial sized biccy batches. Pineapple, nice touch, surprised you didn't add beetroot as well.

IT's like you are covering for TOT's created void... LOVE your projects

I don't think you're alone in finding your projects don't go as smoothly as you thought. Part of the problem is that we are so conditioned to mass produced "perfection" we have a vision of all objects that assume a perfection that can really only be achieved in runs of 10,000 or more. Its good for all of our souls to see the imperfections as well as the thought processes that encourage us to try things ourselves.

nice weld shots!

Looked like a Fokker 50, a machine that really puts you back in your seat at takeoff. The Dutch are famous for their clogs and windmills, in the Fokker they combined them both.

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 :)

Great project, as usual! One thing to consider using as a sealant is Sodium Silicate Solution ie Water Glass. It won't need to burnout.

I got my fire brick from a local ceramic insulation company. The website looked pretty intimidating, the sort of place that supplies goods for big industrial worksites. But I'd heard they deal with consumers too, and after sending an email I was soon offered exactly what I needed at a great price!

There is no such a thing as Canadian food! Maybe poutine and a few other dishes. But in Canada we tend to eat all sort of foods from wherever they come. Great oven, love the build!

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.

Hilarious, thanks, I don’t need an oven, but now I’m tempted to make one...

So good to watch this process. Pizza Naples-style will ofcourse always be the ultimate prize. Don't mention the pineapple. The trick with the glass wire and heat resistant glue for the door is a really good idea. I'm thinking of making a small one for me with one coil and a tiny inside. No cement on the blocks. Thanks for sharing your process and not omitting any steps that didn't turn out to work for you. I don't weld (yet) but rather assemble it with metal plates and thread screw ends and bolts. Thanks, bye! :)

I have a photo of myself next to the musicians as a small child. Pretty cool to now know that is still there!

Nice project. well done.

I'll eat pizza however I want, you can't tell me how to live my life! As for the project, I've always want to build an electric furnace after a few attempts at coal/gas ones haven't worked out well. I hope you can do a lot of fun things with this!

Take a look at the Bar Z Hotshot 360. He uses a blanket type insulation in the door. It swells up a bit to make the seal to the sides. I used it on my over that i made from one of his kits. Works great.

99% on home projects, but 100% on day job! :) Love the video's Cheers

You really got your money back since the day you bought that ice cream!!! 😂😂😂

RTV is high-temp silicone. It's used to make engine gaskets. It'll work better than the JB Weld. Although, the JB is really good stuff. Any place that sells stuff to repair a car will have the RTV.

Nice job!

Sodium silicate is a hot tip for sealing stuff that you still want fireproof =) all tho the melting point might be a problem at higher temps but used for high temp glues etc, sand casting molds etc .. hardens with co2 =)

Love your contents. Greatings from Belgium! Great choice to go with the RAL 6011 for your machines.

Here in Belgium I use a sodium silicate based high temp adhesive, comes as black paste in caulking tubes. Called Soudal high temperature adhesive. It's rated to 1500 °C.

Good build... See you next week...

Yes to the pineapple and yes to the knife and fork for pizza👍. Must be for people from the bottom of the world.

Methacrylate is one of the preferred adhesives for aluminium and also for bonding dissimilar materials. Surface preparation before bonding is key to an effective and reliable bond.

I assume everyone has already mentioned Satanite and the other similar kiln coatings (refractory cement and sealers), but if not, that’s what I would go with. It’s meant to me used in kilns and other very hot ovens, so it can withstand the heat. It will protect your soft bits and refract the heat back into the oven.

hello rotarysmp..good video..thanks for your time

You might want to add a sized fiberglass reinforcement to the mortar, might be enough to stabilize any mortar. A modified mortar, like a self leveling kind might also work but i'm unsure on it's temperature durability

Great humor!

Use glass fiber wire for door insulation. Edit Oh, you already did it :D

Best mortar would be"Water glass" Used for car exhaust repair and available in UK

Sodium silicate as glue? I don't know about comparability with your insulation! Tack welding tip, use a smaller rod to tack, (eg. 2.5 set at 3.2 heat when your going to weld with 3.2), your tack will be smaller allowing easier final weld! All the best, Matthew.,

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

You are such a getto builder. I bet the experts are freaking out watching this. I love it. I missed the part where you made the coils? I think you should have built a much larger unit. Not much more effort but allows you to powdercoat much larger parts

Ah, the red AUA uniforms. Never thought I'd miss seeing them.

For the cement, maybe try going to an oven builder ("Ofenbauer"). There should be plenty such outfits around Vienna. Austria has a tradition of masonry ovens in homes, and these are typically built in place, so these builders may have the necessary materials available for you.

you should have use hot glue;)

Sounds like you need some refractory cement, or mortar. The stuff they use for "gluing" kilns together.

I worked in Hamburg in the 90's before moving to the US. Good to see the airport again after all these years although the empty halls is kinda spooky. While I worked in Hamburg I did consider commuting daily from the UK but spending more time sitting on the M4 leading to and from Heathrow airport than the actual length of the flights quashed that idea pretty quickly. Oh, and I can totally sympathize with you on the screaming baby. The stories I could tell. shudder.

First simp vid with him actually saying New Zealand, aaaaah we’re finally seen!!

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.

A good build and video. Just one question. The main electrode connections at the top and bottom of the furnace seem to have no electrical insulation. Is this the case or did you forget to video the fitting of insulation covers ?

Are you considering to use this with purging gas? It will reduce oxidation of coils and treating part.

Take a look at Blackbeard projects, he just did a gas forge build, looks like he used mineral wool, some coating which he fired to make it solid and then a cement over the top. He is in Italy I think.

Midwest makes the best offset aviation snips ive ever used.

In pottery shops (I mean where you can buy raw materials for pottery), they often sell insulation bricks, ceramic wool and other kiln parts too. Have you looked there?

Can you not get a heat resistant compressible fibre cord seal to close the gap. I have one on my wood stove door but obviously that doesn't get up to the temperatures you are using.

I'd be curious for a follow-up video reviewing what you'd do differently now that you've had time to use this oven for a bit. Interested in making one myself and would very much like to understand what you've learned.

M8. You can't leave us dangling with no videos for like 3 weeks. I've had to watch re-runs.

Hi and congrats for the building. I have a question for you, Is gasbeton panel equal to calcium silicate panel? I wonder if it is the same product and here in Italy they call it Gasbeton which is really common in construction stores were they sell bricks and cement...

That’s handy I’m about to make a burn out oven 😀

The same place that you bought the sealer paste and cord for 'log burners' from, should also have tubes of refractory mastic for use sealing the joints and pipework on log burners and cookers. Its temp resistant up to 1500c, we can buy in Spain (most heating is log burners) The label has instructions in Spanish Polish and French so must be widely available also in your area. The company label says Pyro Feu, hopes thats of help.

Those empty airports were downright spooky. Haven't seen anything like that since Helsinki airport in late November/early December a decade ago.
