  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.
  16. Walnut oil and hemp oil will also cure when left to their own devices. Walnut oil was favoured for oil paint in the renaissance as it dries clear and yellows less over time.
  17. It's for sure confusing. I do love it though. Recently read Neil Gaiman's book on Norse mythology and Stephen Fry's book on Greek. Can highly recommend both. It's strange for sure. Judging by the curve it would be the right circumference. It seems rather narrow though. That being said I don't know how narrow wagon wheels could get. It also has a hole in it that seems to be for a bolt of sorts. I don't know if wagon tires ever had that? Could it be from the suspension of a wagon?
  18. Aah I see. I was only able to find a picture of the front page and a few pages from inside the book without any people on them, so I didn't see many faces. I also found a book that was just called "The prune people" and it just left me mighty confused. I have only three known alloys in my steel library. But it's a start!
  19. Well my pieces have come out of the acid bath and... I'm not entirely sure what to make of it. The smallest piece is surely not wrought iron. Unsure about the larger one, but i know i did a poor job of sanding and prepping that one for lack of time. Interestingly the smaller wagon tire appears to be mild steel wrapped around a high carbon core. Anybody have any insights on that?
  20. Didn't manage to find the prune people viking book, but did find the tre tryckare one (Sounds Swedish. In Swedish it would translate to "Three printers" I believe). Looks like a good one. Irondragon: No I can't seem to see any difference between it and steel. The rust pattern is also dimpled rather than the fibrous pattern you'd expect. Thomas: So far I'm doing a pretty poor job of identifying anything based on sparks. This morning I was grinding down a piece of the wagon tyre with a flap disc to prepare for etching and decided to hit a piece of spring steel as well to compare, but c
  21. Never heard of the prune people before. Another thing to look up. Interested in your adze for sure! Bought some wrought iron from a Minnesota wagon wheel some time back. Decided to break off a piece today to confirm. I think I've been bamboozled. Anybody more knowledgeable than me care to chime in?
  22. My core interests would be tools, knives and eating implements from Northern Europe. Centred around Scandinavia and England. In England I am mostly interested in the area around York as there has been many foreign occupants and a possible evolution of tools and foreign influence would be interesting to look at. From pre-roman to Roman (eorwik) through to Anglo Saxon (Northumbria) and viking occupation (Jorvik) and a little bit after. Within tools I am particularly interested in ship and boat building tools. The metallurgy and chemical composition of tools would be similarly interesti
  23. Thank you so much! That is absolutely wonderful! I am an utter history nerd, so I'll read anything on the subject that I can get my hands on. I'll have to make myself a list and systematically start hunting down all these publications. Gonna have to get myself a copy of the mastermyr find too I think. Once again. Thanks heaps friend!
  24. JHCC: Well now i fell silly. I spent so much time thinking about the blade geometry (where I saw no discernable improvement), that I forgot to think about the stregth aspect. I also assumed as soon as a fairly oval shape was made, the twisting was no longer an issue, but then again the lugs on old designs might contradict that. Thomas: I'll have to take a look at modern axe eye designs and compare them I think. It would be interesting to know how much of a difference there is. I am just about to start chapter three in "The sword and the crucible", so far it is is a very fascinating r
