  1. Well my heat treat seemed to work out alright. Never seem to be able to photograph hamons properly, but here's a preliminary etch. Now I'll have to figure out how to add the secondary bevel in a reasonable timeframe without scratching the blade No humans or other mammals were harmed during the quench. I stuck with the brine and oil.
  2. ActualIy I guess my comment on youtube isn't entirely correct. Thorbjorn Ahman is a great inspiration, whatever Walter Sorrels says on his videos hasn't steered me wrong so far as i know and I'm looking forward to trying out some of the stuff I saw on a few Brian Brazeal videos lately.
  3. Ah, see I don't use youtube all that much for anything but entertainment. As I said, I'm pretty green, but I've been in science for long enough to have a some critical sense of sources I should think. (Y'all need some Norwegiefied words for the record. "Kildekritikk" rolls much better off the tongue). That being said. Metallurgy is certainly not my thing, and I find it confusing to no end. I like knifesteelnerds, this forum and bladesmithsforum. According to knifesteelnerds w2 (which my knife may or may not be) needs to cool in about three seconds. Purely anecdotal, but a lot of the
  4. Just got home from work, so i'm working on that one. I tried saving money by not buying beer for a while, but come payday i was just as broke anyway. Better to be broke with a carton of beer than without i reckon. But if you'd ever try my homemade ginger beer I'd say you'd argue that got less toxic after processing. Now i'm still very green, so apologies if i get facts and terminology wrong I'm running on the assumption that the file is made of something akin to w2, so fairly low hardenability. 3 seconds in brine to quickly get it over the curve to convert as much as i can from
  5. Haha! I might give that a go. I'd rather not end up with loads of toxic waste. Or maybe i can trade toxic waste for less toxic things, like a carton of beer. On that note though, could i simply force rust my spanners? (One of the lesser known Jedi tricks). Also. Working on a file knife for a friend of mine. I've already normalised and thermocycled it five times. Yesterday i noticed the tang was a bit off centre, so i clamped the blade cold in the vise, and gave the tang a couple of wacks and it's straight now. But do i need to redo the normalising? Also the hardening plan is c
  6. That is certainly something that I didn't find during my sleuthing sessions. Copper would certainly pose a bit of a problem if you were to try to forge it as is I imagine. (I'm assuming the chromium might disassociate anyway but...). Definitely good thinking, and I'd never have thought of it but it looks like the reason chromic acid is used is because a chrome anode does not readily go into solution, so a lead anode (or cathode?) is used instead. I wont pretend to understand it, so I hope someone can set me straight on that one as well. I sure like your attitude to the question.
  7. Thanks Frosty. That does indeed seem to be the case. And yes. I don't know how I would deal with the acid solution afterwards. Can't just neautralise and pour down the sink for that mix I reckon. But there's copper in it? I thought it was just a vanishingly thin layer of chromium on top of Nickel. I tried vinegar (at least I think I did). Didn't seem to do much, but then again. For all I know the chromium could have been stripped away and the nickel could still be there. (The nickel remains shiny right?) I often see it reckommended to grind the plating away, but that seems to be an e
  8. Picked up a bunch of spanners on a garage sale that I'm wanting to make hooks with. Mostly chrome plated it would seem. Now I've heard a lot of talk about the dangers of chromium poisoning, hexavalent chromium, chromium fumes and the likes. I have spent a few days reading about the subjects and believe I know how to take reasonable precautions. Crucially: -Coating is most likely trivalent chromium, but readily converts to hexavalent chromium at the highest rate between 200 and 300 degrees celsius. -Hexavalent chromium reduces in the presence of organic material (That would be ho
  9. Thought I'd just post a glamour shot of the first curved knife.
  10. Thanks. Good to know. I've heard higher carbon has more of a ring to it as well, so I was wondering,
  11. 400 000 tablets?? I hope it's large font, otherwise I'll be reading for a while. Thanks for the suggestions. Some of the things I've been working on. The old viking knives are finished. I decided to finish those with files and a natural stone, figuring there wasn't much sandpaper around 1000 years ago (I don't know how authentic my finish is, but i'm trying). The stone was a Japanese aka-monzen (I think) and has left a pretty dark patina. The kitchen knife should be just about ready for the quench, but I'll fit the handle first. The kiridashis need a bit more time on the fi
  12. Is it mild or another alloy? How's the sound? (I've been wanting to make a triangle for my kids).
  13. I would be very interested in reading about that. That's all very interesting as well. Would that all have survived as oral traditions through thousands of years do you reckon?
  14. For sure. The Australian aboriginal peoples actually have oral traditions detailing the end of the last ice age. Wonder if other cultures have something of the same sort. (I don't think there is any stories older than the First Australians have, but it would be an interesting comparison). For the record, currently reading little bits of Konungs skuggsja, or the Kings mirror/ Speculum regale, and the insights of the author into the workings of the natural world is very fascinating. I guess that's a bit off topic, but thought it worth mentioning.
  15. My library is going to be so great thanks to you guys. Do you have any examples of parallels? Long ago I used to think most ancient peoples hardly knew of each other and had little interaction. But clearly that's not true, so there was probably a lot of sharing of myths as well.
