  1. I would assume ( you know what that means ) That if you can draw a full vacuum in a glass bell jar then you should be able to do it in a pressure cooker. Pressure cookers generally run a 15 lb psi on their highest end at sea level. I don't know if you are at sea level or not ,but if you are the HIGHEST pressure you'll be able to exert on the outside of the container is 14.7 psi. The pressure of the atmosphere.If your elevation is above sea level then even less. PS There is a fellow on YT that stabilizes his wood for handles in a mason jar!
  2. I'd be interested in what the braking system is on this hammer? It seems to stop with the tup up almost all the time.
  3. This is the method I would use and is really the only economical method for a small shop or small run of parts. My 2 cents
  4. You can also find a VFD on ebay large enough to run your hammer. Probably cheaper than most rotary phase converters.
  5. I have no way to up load a drawing...sorry. But think of it this way, if all you had was a piece of 1/4" x 2" x 8" how would you derive that form if you couldn't forge weld but had a hot chisel? I'm not saying by the way that size material is what you should start with for this particular project. It's just an example from which could could make the general form desired.
  6. If forge welding is going to be an issue, why not split a wider bar and draw out the bottom leg?
  7. Steve sells, It seems NATKOVA's English maybe better than your's considering it's your native language :) Or perhaps it's just because you were trying to beat Frosty to the punch? :)
  8. I've bent antler with boiling water and a little vinegar. I don't know what or if the vinegar does if anything but it was what I was given as instructions. Clamp the antler between plates, vise whatever to straighten. Have it hot,well soaked so the heat is all the way through and go SLOWLY. Keep a sharp eye out for beginning cracks and reheat if they start to appear.
  9. For a hobbyist you can get into tig with scratch start and a DC buzz box. Not very expensive, especially if you by the buzz box on CL or at a yard sale.
  10. Here is where to get your info. http://www.leesauder.com/smelting_research.php
  11. The flux can probably be chipped off by lightly hammering and wire brushing in that order. As far as forging try a piece and find out.
  12. Not all welding processes are the same.Some are constant current and some constant voltage. http://www.lincolnelectric.com/en-us/support/process-and-theory/Pages/constant-current-vs-constant-coltage-output.aspx

    Jake Brown

    Jake, Was my assistant here at Peters Valley School of Craft for two years. He is a young very accomplished blacksmith who at his age of 29 has experience beyond his years. Before assisting me Jake served an apprenticeship at The National Metal Museum in Memphis, worked for the Museum of Making with Japheth Howard in Canada and Glenn Gilmore in Montana. Jake has been diagnosed with a brain tumor. As of now we don't know if it is cancerous or not and have no prognoses. I'm posting this to ask for your prayers for Jake and in hopes that some of the many people he knows will see this. Thank you
  14. That's a Fairbanks hammer in the school photo.
  15. You should all remember that if the hardies are forged to 1" they are going to shrink as they cool also. Though I doubt it would be as much as .025"
  16. Any selfmade Chipping Hammers!? If chipping hammers made themselves we wouldn't need any blacksmiths. :)
  17. Beautiful work Robert !! Seems as though pittling about suits you quite well. Keep up the hard work, the extra effort required to accomplish what you've done shines through in your finished work. By the way, the northern equivalent (New England) to "pittle about" is Dubbing around, it's obviously not a bad thing. :)
  18. Your hammer may have felt dead because the handle was loose in the head. Solve your original issue with the handle and you solve all its problems.
  19. It could be a number of things. Since you ran it with one belt with no problem are both belts coming off now or only one? If only one since the pulley is crowned the belts should be two different lengths. It could be alignment as you said or it could be that the bearing of the pulley on the LG is has finally become worn and started to wobble,thus throwing off alignment and tension both.
  20. Here is the episode you folks are referring too. http://video.pbs.org/video/2292087803/
