  1. I am melting some steel today..it has been a while since my crucibles did not fail.......having togo back to doing what I did long ago. Will post a picture only if experiencing great success.
  2. OK that was 0/4 and I am taking some steps back to rethink this baby..I know what I want but am not sure how to get it. Si se puede.
  3. Thank you for all the replies here ..interesting stuff. It looks like it will be a 9" diameter SS pot with 3/4 " clear plastic ( poly carbonate or plexiglass ) and a Viton 1/4" seal. BY putting a slight taper on the hole in the plastic the 3/8 pipe thread can just be inserted as if the plastic were threaded. Jan
  4. When looking at manufactures vacuum chambers , i noticed some are labeled not for stabilizing wood. Does anyone know why that is the case. Some mention the cactus juice name specifically.
  5. In planning the next melt(s) I have some serious problems to consider, the crucible showed a lot of tearing cracks indicating a great degree of shrinkage ( I could see the height of the crucible getting smaller during the melt) . To assure a greater degree of melting I will boost the carbon content to 2.0% carbon by adding 800 grams of cast iron to the ingot. I am stuck with this particular crucible for about 8 more melts and will have to shift to a higher carbon content. now I should get a 2000 gram or a 2400 gram ingot ( that is good ). I will need to make a new furnace having the air/gas inlet closer to the bottom. Jan
  6. I guess I have a new learning curve to climb. The added stand created a cold area at the very tip of the crucible the cotton pad I placed on the bottom, before dropping metal into the crucible, did not incorporate into the melt. I may have also place the crucible a little low in the furnace and may have been too frugal with the propane as not all my anchor chain got incorporated...so it will be cut in half and remelted at 50% at a time I will post some pics later. melting 1636 grams must take a little longer than 600 grams of metal. Jan
  7. While waiting for the technology I thought I would try to get some larger ingots in play. This crucible contains 1637 grams of metal and should result in about 1.5% carbon steel.. I have added a little lift to the round bottomed crucible so it will stand up without falling over. This crucible is very close to the central Asian crucible shape as shown by Alan above. I will melt tomorrow and pull the crucible the next day. I am also experimenting with some larger crucibles having a lenticular shaped ingot.....these and the one shown here will go up to 2000 grams. This crucible is not full. Actually the crucible will hold about 4000 grams but I would have to add materials after the initial ingredients are molten ( we can do that ). Now 2000 grams is 4.4 lbs. and 4.4 lbs is 14.7 cubic inches of steel if our imaginary sword is .25 x 1.5 x ( X ) inches X would be 39 inches long ..plenty of metal at 2000 grams. Here I have assumed a lot of grinding to be done, many of the historic swords weighed just over two lbs.
  8. Looking good, making the mechanics of smelting an easier process is a good idea, I am working on that as well ...interesting structures...thanks for posting.
  9. I am looking to buy some Stainless Steel Thermocouple wells like those used for salt furnaces..does any one have a good source?
  10. Wile waiting and looking forward to the technology presentation .. I think I will go for it as well..I need an ingot of 1800 grams to make a sword. So the criteria are ..a large ingot, a solid sound ingot and the patience/luck to forge it ( no my name is not Peter ) to a pattern. The large ingot should cool nice and slow for maximum dendrite size. Right now I am just forging old ingots to see if I can avoid breaking them.
  11. I am still making my forges this way...I cast the shell with refractory between two paper tubes....this shell replaces the clay flue inner shown in the pictures. The build is easier for me if the air/gas mixture comes in at the center..I add a deflector later in the build to allow the flame to rotate in the furnace coldspot.m4v
  12. Thank you all ....I was under the impression there was a function called " manage attachments " ..I think this may have been so on a previous version. Sometimes I find I have posted information no longer valid or a photo that was associated with another post.
  13. Please assist me in figuring out hoe to manage my attachments...thank you.
  14. TRuGrit sells silicon carbide belts made to run wet...check with the glass companies they always grind wet with belts. Do as much as you can with 4.5" grinders you will be surprised.
  15. Thanks for the rep lies guys...I like the idea of quenching quickly past the nose..my tendency to fumble makes me want to stay with tempering.
