You are welcome Steve.

Considering that the underlined word Blacksmiths is actually a link to blacksmiths depot, yeah, trying to sell.

Well, it is a rather small piece of steel being placed on a much larger, cooler piece of steel. I thought that I recall some advice to preheat or at the least, to warm the anvil.

Since you are in Denmark and you mentioned winter I would ask if your anvil was too cold?

Here is what I did for mine:

Hey, I'll take that as a compliment. I have a BA in Telecommunication and Film. I have also taken a few Material sciences classes. However, I program industrial robots. I suppose that I could add that, as a kid, I was kind of a junior mad scientist, with like three chemistry sets, test tubes, flasks, etc. Where I program robots we do thermal spray, a variety of processes that adds material on the surface of parts to enhance properties or otherwise protect from heat, wear, corrosion and so on. A large part of the work is to apply TBC's, Thermal Barrier Coatings. This would be mainly Yttria stabilized Zirconia. That is how I have gained what I know about this material. I also used to be a thermal spray operator at a couple different place. That was how I got started in robot programming.

Hello to you as well. I read that other thread too. You could choose to not use Borax for flux obviously. I don't think I would want to go messing around with any Chrome compounds except maybe Google Chrome. The reason for using Yttria stabilized Zirconia is that the Cubic phase is desired, and if not stabilized it can more readily undergo a phase transformation into monoclinic resulting in a volume change which can cause failure.

I had commented on another post which is similar in nature. I bought some Aluminum Phosphate already made because I didn't want to go messing around with phosphoric acid. It was not cheap, to say the least.

I have dabbled a bit in refractory experiments. While MgO has a higher melting temperature, Zirconia is known for it's toughness and better insulating property. In particular, Yttria stabilized Zirconia. I got some waste powder from where I work. I attempted the first ones using diHydrogen Alumuminum Phosphate as a binder. Not especially successful. My next run I will try aluminum phosphate as a binder.

Busch precision ground cast iron surface plate. You will see it for sale on some tool supply sites. Also: https://en.wikipedia.org/wiki/Surface_plate

I was like, regular what? Then I guessed that you meant regulator. Is there something wrong with your present hose? If not, consider installing a regulator inline.

The AI answer indicated that copper is a key alloying element. There are also other grades like 15-5. Here's a real rabbit hole for you: what alloys are precipitation hardening

Plug this into your preferred search engine: 17-4 ph stainless steel

Google lens found a math on this guy's museum site, but there is no written info about it. He has it on pinterest too. https://www.pflugmuseum.ch/hammerschmiede.php?Lang=en

Helicoil, good call.
