  1. it really looks like ancient moire, I will wait for the looks when you have put it to shape and shine, Niko with a slight jealous look to Finnland terveisiä saksasta
  2. looks like a great stand, three legs will keep it straight on nearly any floor, too, fine work to a beautifull anvil my only point of critic is, it quess it will be very loud, "singing and shouting" did you try that out? or do you have some big magnets to put on the horn? best regards
  3. nice work, Qiang! so you did do another smelt? looks like a very fine moiree and Niob seems to be a good choice give us some pics when the Yatagan is ready best regards
  4. pardon me, but the wood looks more like heat treated alder-root to me for curly birch there is not much curlyness in it normally the Finns are rather strikt about these things and Sams question is really interesting best regards
  5. Löwenruh, German for Lions rest, or lions peace Ruh= place for having peace Ruhe= Quietness eesti= Uni , Rahu or something like this en osa Eesti, vaan vähän suomea best regards and nice pic! from a great place I like Tallinn
  6. nice prills in slag of glass , that's what I think, and if so: probably blue because of chromium, Alan chrome makes glass blue if you use clear glass as "slag" very nice pic, Niko!
  7. Super place, and nice pics, thx for sharing I can understand that you love to see and meet people like him and places like that in the north, myself I like to be a bit more east than that, in Finnland liebe Grüsse
  8. @ Zeb: I quess it happened because the charcoal had already burned away from the crucible by the time the first nails reached the bottom of the tube, the pieces of coal where middle sized, not too big, and it sunk down every two minutes or so by about two inches, so I filled her up again with coal and @ Mark: I feeded only a small amount of nails, about ten at the time, but I can not say much about the nails, they seem to have been standard material here in Germany, when the house was build in about 1934-36, small heads to make them sink into the wooden floor and about three inches long, this time I did not cut them into smaller pieces... maybe I will try to give the air in straight next time, but then I will use some of the pure iron (sandform) I still have from Hoganäs. I had used it for making Wootz. I hope to be able to use the newly melted stuff for another crucible run. I will keep you updated when I will receive the material from the local water supplier. The idea is in my head for quite some time, since the first rennoven I was with was run with Oolit material from the nearby mountains with only 24-26% of ironoxide in it. And it sure gave some poor results. So I was rather astonished when a friend told me about the amount of ironoxide that they gather in their filtersands. If it turns out to be good for a rennfire, I will try to get material from different places, since there is few manganese in some aerias and more in others (like in the late town I lived). That should give material for forgewelding with clear contrasts, and the sand in it should help to make a good glassy slag. So far for now...
  9. after all this was just a try because I am still waiting to receive some buckets full of filtersand from the watersupplies, the guy there said that it was over 65% of ironoxide in it, when they wash it out, sometimes even more, so I am waiting for my chance to make steel from water, but in a traditional ren-fire, maybe about the same size of what I just had oh, there should be some 15 or more % of mangan in the filter sand, too so the iron should be "black" then, I was promised some datasheet, too sometimes it is really nice, when things around you are really organized regards from lower saxon
  10. thx! really looks like a power-blower, no wonder that you use a ballvalve to simmer it down a bit, I did put up some pics of my small device in my new threat cu there
  11. so here are the results from sunday morning: cracks on both sides, a bit burned but intact the crucible I had put the hole in simply held some ashes, nothing else: the nails had melted to the end of the tube: and this came to my hand: and this is the place after cleaning up: as you all know, we Germans are very fond of everything cleaned up properly I will give some more infos when I made new pics and looked at the carbon content best regards!
  12. So I took some more pics as light faded, the whole thing got really hot, I thought and soon there where two cracks in the "chimney-wall" but the insulation and the wire did hold everything together and it was nice to watch the little sparks go up no complaints from the neighbors, because the blower made simply no big noise (my wife was pleased, too)
  13. As I wrote in Niko's threat, I tried to play with the aristoteles way of giving mild steel some more carbon, throwing a bunch of old nails into a charcoal fire. I have kept the old nails from the kitchen flore from the 30th when we did the renovation of our house, so there was enough material to try out what others have done before...oroshi-or orishigane, whatever it is called, here it is trying to get some decent steel from "crap" so I looked around for what I had, an A7 crucible (a bit too big to fit my old smelter) some stainless tube (22mm) an old flower pot I filled with sand to have a stand, some fire bricks, rests from a ceramic insulation blanket(for up to 1300°C, leftover from making a gas forge), a bit of cement, too, so take a look for yourself I started at about 16:00 and ended 21.30, burning about 4-5kg of hardwood charcoal and throwing in 1,6kg of rusty nails. I did not waigh the outcome yet and sparktest is still to be done, so here are the pics: here is the small blower that I used - coming handy from a PC, put into a small box with holes to reduce airflow if necessary - I use it for a gas forge... it is probably why the proceding lasted so long in comparison with what Niko made with his power-blower so after raising the little pile I started the fire and added some nails
  14. the whole thing looks very interesting, so I tried some "playing with Aristoteles" too,on the weekend, funny enough it lasted over three hours to melt down about 1,6kg of old nails I had taken out of the old kitchen floor (from the 30th). So, Niko, you made me curious, since your big set up needed only 70 minutes to burn down your stuff, so I think that my little blower did not give the amount of air you are using, I burned about 4-5kg of hardwood charcoal, probably mine made more cast, too, I did not check with sparks yet, Could you pls give some details about your blowing-system, Niko?! I will start another threat to show pics and results, if that's OK best regards Ja terveisiä!
  15. I allow myself to quote from Greg Obach "replication of Wootz": >>Cutting Edge Durability of Wootz The beginning of this section is devoted to testing the edge retention and cutting ability of a wootz knife blade. The first test is the ability of a knife to cut through a free hanging 1-inch hemp rope. The process of edge testing used is similar to the test detailed by the American Bladesmith Journeyman exam. The exam information is further explained on the http://www.americanbladesmith.com/ABS_JSTest.htm website. The knife used in this test was a wootz bowie knife forged out of similar steel to the prior test pieces. The bowie knife had an edge ground onto the bevel with a 600 grit aluminum oxide paper and sanding block. Once proper technique was used, the knife was able to cut through the rope on 3 occasions. On the second part of the second part of the test, the blade was used to chop through a spruce 2 inch by 4-inch board length twice. The edge test was performed three times and showed no signs of a chipped or compacted blade edge. The blade carried no visible damage from the previous tests. The final test was to shave hair, showing that the keen edge has remained intact through the previous tests. The knife remained largely sharp on the vast majority of it’s surface and could shave hair. The hammered bevel blades performed the tests with the same results as the ground in edge knives.<< this text was easily found on the web, did you read that, Ed? you can find the whole article on: http://users.unitz.ca/gthomas/myweb4/replication_of_wootz.htm I thought it was standard knowledge by now

    nice handle, very traditional, too I like to make them myself, too (mostly of finnish birchbark) the line where you start the bevel seems a bit high when it comes to the tip and it looks like you used copper instead of brass, might turn green very fast if so best regards
  17. Oh, I do like this kind of hammers, too one of the first that I made myself looked like this: and it is good if the angle of the handle is not 90°, but slightly less regards
  18. just put the two words into goog... click on pictures and there you are, over a hundred in three seconds best regards
  19. or you will do the direct reduction in a crucible, I know you have all the stuff that you need for that you will nevertheless have to cover the heap so rain and wind will not have too much of an effect on it I would like to put some three kg into a crucible together with some fineground charcoal, just to see what it will look like after three hours in my smelter... well, my workspace is slowly evolving... best regards
  20. Why don't you use this design: http://www.bladesmithsforum.com/index.php?showtopic=23817 or any other that you may find and get started, like these ideas from sweden: http://zoomin.idt.mdh.se/course/Goran/Reproduction_of_Damascus_steel_wootz_patterns_and_blade_forging.pdf personally I find your approach a bit annoying it does hardly make me feel to be ... helpfull there is more than enough info on the net, especially here and on other forums, in different languages even, French, German, Swedish etc... just put the right words into any search-engine edited 07.22.
  21. looks very stunning, Niko, fine work would have loved to see your work personally, maybe next time pysy terävänä!
  22. moikka, ja kiitos vimeisestä, Janne! It was very interesting to follow a multifiring of crucibles, the oven works fine, and as Janne wrote, it needs a bit more air to come up to temps, the charcoal used was a bit wet though - and for my feeling the space a bit niffty for five crucibles. but with some more coal or cokes in the mix it should work fine. Janne cleaned out the airchannels with a vacuum first, putting the crucibles on little "posts" about 3-4 inches high, they sat on the airholes and had little grooves cut in the undersides for the airflow we did smallen the pieces of charcoal before showelling them inside the cake out of the biggest crucible in the middle turned out to look quite nice two of the smaller ones looked like half cooked, with rests of the iron baked together on their tops quite a workspace there I must admit and a perfect day to learn more Finnish I loved being there a lot and man: Janne, you do have some very fine "visa-koivu" 'Betula pendula var. carelica' we will stay in touch @ Jan: not salamander - although by the way he is using fire one might think so, but "kruunu" means crown, kruunari: "for details look at Janne`s answer"
  23. looks interesting, Janne, is there anything that I should bring along when you start to fire this little monster? like a couple of clay-graphit crucibles? Achim Wirtz gave me a nearly done melt from his tatara left-overs, to do a remelt, in this years solingen fair a nice and very clean steel with a layer of slag on it - I whish to refine, it will be about 850gr I think I guess bringing firebricks to Finnland from Germany is not really a good idea moron
  24. 790 - 820°C in lukewarm oil (so go a little over non-mag, but don't wait too long)if you want you might repeat that then two times 180° into the oven for one hour with a water bath inbetween and you should be on the bright side...
  25. saw blades are often made from 75 Ni 8, which makes them a good bladesteel, very bright and silvery looking in damascus-steel about slashers I do not know...
