  1. Excellent work well done figuring it all out, lovely blade
  2. Any results Will? Am just reading all I can at the moment would love to have a go at Wootz.
  3. Are these a UK based company Owen?
  4. Hi guys, just wondering if you had to choose a diy power hammer which one would you choose and why? Frankenhammer Build Manual https://www.amazon.co.uk/dp/1502928728/ref=cm_sw_r_cp_apa_i_GFprDbQ516T6M Or perhaps another design I haven't seen. Thanks
  5. I'm going through the same thoughts at the moment, I have a simple recipe used in the gingery book, it's just fire clay, grog, and potash feldspar as a flux, the problem comes with firing them properly, I was talking to a guy whose played around and with a home made rig he has a 50%/50% success rate, he also tried the refractory he had left over and that was too insulating so his cast iron didn't fully melt, I'm thinking of teasing out some kaowool and mixing that in in the clay to help. The advantage of home made crucibles is that you can shape the how you want so you'd end up with a more forgable shape
  6. Castable refractory is the most rugged lining material I use 1700c in my furnace 1 1/2" thick with a 2" gap with vermicultie, the bottom is droppable if you get a crucible break, if I were to do it again I'd skip the vermiculite, and use fibre board for forge linings instead, if you can afford it the for "The Artful Bodgers Waste Oil Foundry" by Colin Peck his design is innovative and he's built several furnaces the culmination of these builds and years of experience is in the book a good read!
  7. Amazing temper colours, sorry I missed it, though am finding out what a pita that stuff is like to forge into a proper steel keep up the good work guys
  8. I know the Whitechapel bell founders in London used to use willow rods to stir the bronze melt, it was later discovered that the salicylic acid in the willow bark acted to de oxygenate the melt the same may be true of copper so I guess you could chuck a couple of aspirin in

    Welding Tangs

    Does anyone scarf then fireweld tangs on as a traditional blacksmith would have. I've done a lot of forge welding and struggle to make the scarves invisible so tips are welcome too
  10. This may be of interest http://www.bladesmithsforum.com/index.php?sh...er+quench\]
  11. Hi Dmitry, Have bought the book and assembled the parts for the furnace need the time to build it now. What is your mix I have the gingery book on making crucibles, and his mix is 38% Fireclay, 2% Potash Feldspa, and 60% 20 mesh Brick Grog. Ant guesses to haw it may perform? Thanks John
  12. Hi Dmitry, can I ask how and what you made your crucibles from? Cheers John
  13. you could use a piece of flattened scaffold pole was shown that and you can cut it to a height most suited to you not dictated by vice or anvil
  14. In these situations a press is better if you've got one I go and use a mates a vice does in a pinch
  15. Some good hints and tips here http://www.knifenetwork.com/forum/showthread.php?t=46184
  16. Does the grade of wrought iron matter I've some cheap hurdle bar which has to be worked at a low welding heat otherwise it can crack would it be suitable?
  17. I've used most belts now and Ceramic last 3-4 times as long as Zirconia or Al Oxide and cut cooler they're idea on hardened steels for not destroying the temper. As already said Zirconia are only for roughing out and are fine up to 120 grit these also last longer the Al oxide, though not much. Al Oxide are cheap and readily available and are ideal in fine grits I've tended to glaze the coarser one compared with Zirconia. All belts will clog when used with soft materials ie wood, antler etc. I've not tried micron belts as we can't get them yet in the UK. This is all based on my limited experience I've only owned a grinder for a year so will bow to greater experience.
  18. I've heard it called slap quenching by a archaeological smith used in traditional sword making
  19. Ain't that the truth was a real special one as well, well done!
  20. Yah Howard you were mentioned on many occasions and there was a toast to absent friends though I doubt many would remember it. My only fear it that it was such a special and amazing event how do we better it Owen you are truely amazing and unstinting in your efforts to foward the UK scene. I'd also like to thank Owens Grandad whose site it is so thanks Gramps.
  21. Goos Efforts! Any ideas what caused the failure, and do you fire the crucibles first in a potters kiln?
  22. I've mixed it with both 15N20 and 1070 with good results people say it's trick in the heat treat cause of the chrome in it, but I've had no probs yet.
  23. Will do once I've built the furnace.
  24. What do you mean the cakes plop out a friend has made wootz and every attempt destroyed the crucible or at least the ones I saw is that too much glass? I would definitely buy a crucible for casting purposes as I want max handling strength, but didn't want to keep throwing $60 away at a time on damaged crucibles. Was all may have a rethink, or join a pottery class and get 'em fired properly before use.
