  1. Nico, You live in the same town that I do. Which school do you go to? Science fair was my life when I was middle/high school, and I have done a bit of judging over the years. I have some left over bits of damascus that I could give you if that would help with your experiment. I also have a small oven that you could come over an use if you want to do something with grain growth. Best... -Brian
  2. I had an intern recently that was fond of saying "Neato Dorito", and somehow that is all that comes to my mind right now... You said you filled the tree with 2% nickel powder. Does that mean you mixed 1084 powder with 2% nickel powder? That's what I had assumed, but I didn't expect the tree to really come out that bright.
  3. A one-fingered salute mind you... I put the snow tires on my car over the weekend. This pic was just barely 24 hours later. I've been too busy lately to pay attention to the rest of the world, and didn't know this storm was coming. Good thing I didn't wait another day. This car is fine in the snow with dedicated tires, but it's a hand-full with the summer tires. It was 60F and sunny when I was working on the tires, and in the pic it was 15F and 3" of snow. I know this is trivial in terms of winter weather, but I'm grumpy because I'm not acclimated yet.
  4. Dude! I"m playing catch-up here, but that carving! I wasn't expecting that, and now I too feel really inadequate
  5. Looking good! As Indiana Jones said, "It's not the years, it's the mileage". I know a few little bastards I'd like to use that on.
  6. Yeah, what they said, that is "just right". Is it heading for a reenactors belt?
  7. Wow, I get busy and stop paying attention for a couple of days while Gary goes all Mr. Miyagi on us! Very inspiring. Now I have to go practice... ...right hand wax on, left hand wax off... ...wax on ...wax off
  8. Thank you for your continued efforts to keep the forum running Niels!
  9. Or, is it just me having security warning issues?
  10. I think I just heard @Jeremy Blohm start his truck... (...and I live 4 hours south of him!)
  11. Thanks Alan, makes perfect sense
  12. What line are you seeing? (I'm trying to lean, and not being a smartalec) I see a groove around the circumference, but would have assumed that was some sort of wear if I ran into it in the wild.
  13. That is flipping brilliant. It's going over my office door...
  14. The stuff at hardware stores is generally more along the lines of A36 and not likely to be 1018. The metallurgy of A36 isn't very tightly specified, and it doesn't matter what all is in the steel as long as it meets a minimum strength requirement. That means it can contain a number of other elements that make the welding less than predictable. No harm in playing around with it, but if all of the other parameters seem like they should be right, you might end up frustrated for no good reason. I absolutely agree, and almost wrote that. "Slather" was used to make the process sound less than attractive
  15. This has already been stated, but just to make it clear, flux has two purposes: 1. Primarily, iIt covers the metal with goo to keep the surface from reacting with the air around it and forming scale (oxides) 2. Secondarily, it has some ability to dissolve oxides that are already there. (It can't clean off heavy scale though) Now that you know what flux is for, you can reason out how to use it. As soon as the metal is hot enough to get the flux to stick to it, put the flux on. Hopefully you get this done before the metal is hot enough to create a heavy layer of scale. The molten flux will keep the metal clean underneath until you have time to close the weld. Temperature and cleanliness are the key things. For mild steel you will need to be at nearly a "White hot" temperature. I use 1095 a lot and would describe the temperature for welding it as a "butter yellow". If you use borax, it has a nice tendency to start to boil frantically at about the right temperature. I got away from using flux for quite a while, and would encourage you to do so as well once you get the hang of it. It's messy, and eats up the forge. It can also become an inclusion in your weld. A while back I started doing some welds that seemed more complex and I krept back to using flux as a security blanket. I could almost "Feel" the scale forming on the unwelded bits of my work, so I started slathering things with borax again to keep them safe
  16. A good rule of thumb is that a strong vacuum will be 15psi. Find the surface area of your lid in inches and multiply by 15 to find out how many pounds of force are on it. It does add up pretty quickly.
  17. That forward facing finial on the guard looks familiar. Seems like someone posted a bayonet with a similar feature on here in the last couple of years. Could it be an older one that had be reshaped? The wonky barrel band may have simply been squashed at some point.
  18. Muy bien. Nice work, and I enjoyed the story
  19. Looks good, congrats! You've found a rabbit hole within a rabbit hole
