  1. If a file skates off it, that tells you it's hard. For a real test, as you said, put it in a vice and give it a smack and see if it breaks. I have to say, 5160 (coil spring) is not my favorite material for strikers. Old files, crow bars, and old tire irons (not the chromed ones, nice old rusty ones) are better. Water quenched 1095 always works for me. Geoff
  2. I spent the day making and fitting ironwood bearing blocks for a spinning wheel. Many trips to the shop and back.
  3. You could use existing hammers as a starting point. I admit, not as much fun as doing it all your self, but you could make a set. Ball pein hammers from 2-16 oz in 2 oz increments. g
  4. I don't know much about such things, but there was a local wood carver named Dudley Carter. He used a small and much modified double bit axe for roughing. I wasn't able to find a picture of him with it, but I remember seeing one. It was quite small (1.5 to 2 lb ? Maybe less) and not much more than a hand span long. I remember seeing a pic of the axe. The handle was short, not much more than 12 inches and he held it right up under the head. One side was sharp, but not too sharp, and one side was stropped to a razor edge, He did most of his big roughing with a felling axe and a doubl
  5. Just needed to do some forging. I did a couple small knives and a start on a damascus integral, and this stuff
  6. It sounds like you had a skin of decarb that you were able to grind through to get to the hard steel. What was the steel and your process? G
  7. VFD's are useful in that you can run 3ph motors on 1ph power. In the US it's nearly impossible to get your local power company to pull 3ph into a non-industrial zoned property. So we have to fiddle around with phase converters of some kind. I have a VFD on my grinder and a big rotary phase converter for the press and a couple of other machines. VFD's also can give you speed control (depends on the VFD) and some other programable features like soft start and stop. What I was thinking about was using a VFD hooked up to some sort of peddle to control my hammer, as opposed to the slack be
  8. On a FB forum there is a discussion ongoing about using VFD's as the control for a power hammer. As always, there are those who insist that it can't be done. The main issue (for this side of the argument) is that the speed control of a VFD causes power losses at the motor, and for that reason a VFD is not a good choice to replace a clutch on a power hammer. My experience with VFD's is limited to my belt grinder. In that application, I can't say that I have noticed a loss of power. Does anyone here have more experience with VFD's in industrial settings? I think the idea is
  9. I don't know that this is true, but I have heard that in the Colonial period they would burn down buildings to recover the nails and other hardware. g
  10. Speaking of how much labor it took to build the world as we know it. This is a hand spindle Up until about 1500 (when the first spinning wheels became commonly used in Europe) all fiber for cloth was spun on something like this. If you've never seen one used, you wrap the raw fiber around the hook, give it a spin and drop it. The weight pulls the fiber into thread and twists it. You then wrap the thread around the shaft and do it again. Larger ones were used to twine threads into yarn. Ever scrap of yarn for everything from clothes to blankets to sails was made this
  11. I have also used the threaded rod idea for a tang. In fact Salem and I were talking at a show several years ago and I "confided" in him that I had done this and was worried that people might think it was cheating. He laughed and said that he thought he was the only one who had done it. If you have enough room to get 4 or 5 threads engaged (more is better) I've never had a problem. It does let you get a totally flat mating surface on the bolster without any fuss. I use grade 5 or better bolts and some kind of thread lock (JB weld is good) and I harden the bolster to make sure th
  12. Thanks so much, Alan. I'm glad to have your considered opinion. I know that certain things were valuable trade items, pre-contact. There is all kinds of jaspers and opals from Washington and Oregon that show up well outside the region. I had an archeology professor in the 70's (Garland Grabert) who had worked on a village site in the Okanagan, about 2500 years old. In it they found a spindle whorl of an unknown material (he brought it to class and passed it around). About 4 inches across with a hole in the middle. I was made from a hard creamy material but was not bone (whale bone w
  13. Very nice! I really like the ones with the mid shank twist g
  14. Sigh Some 40 odd years ago a long time friend took a trip to Ohio to visit family. While there, during a hunting trip, he found some arrow heads. He gave me one of them and it has bounced around for all that time. I bumped into a knapping group online and decided to ask about the point. They are about evenly split between "it's real, Hopewell (maybe), cool thing" and "Fake, made in India, can't be real, don't be stupid". I guess that's what I get for asking a bunch of online "experts" to evaluate my crappy pictures of a thing. For the general public, I believe
