  1. Glad you got it finally finished! I would also be interested in more historical references of serpent patterns. When I looked at them a few years ago, I did not really find much of interest.
  2. From my perspective, it was a general exercise. Jim ended up visiting a bunch of smithies in Norway and Sweden a few years ago. I believe this is one of the simple axes he observed there. I mostly wanted to get a sense for the process and an excuse to actually spend two days blacksmithing. My usually shop time is unfortunately only a couple of hours each week at the moment :-(
  3. Here are a few more pictures. The axe head right after forge welding: Here Jim is forming the eye on the mandrel: And the axe heads after the eye shape has been refined:
  4. The starting bar was 6 1/2" x 2"x 1/2" - mild steel.
  5. In preparation for welding the eye, the transition to the blade is upset to give it some more material: Then the surfaces are cleaned and prepared for welding with some borax: Afterwards, the piece is bent so that the blade parts meet perfectly and are ready for forge welding:
  6. I did not take any video as that would have easily doubled the amount of time but here are some photos. Using a center punch to show the lines where material for the eye is going to be separated: Fullering on the line - the goal was to split the punched dots in half: With the material separated, the rest of the eye is fullered to increase the width to about 3 1/2 in: I'll post more pictures when I have some time. That said, watching Jim demonstrate all this makes you appreciate the skill and experience to do this efficiently.
  7. I took a couple of days off work to spend time with Jim Austin in Oakland and take his axe forging class. The objective was to transform the bar of steel into that axe head: This is basically all forging work without really much grinding and or filing afterwards. We made two axes and here is the one I made (under Jim's excellent tutelage): If you are interested, I can also post some photos from all the forging stages.
  8. Here is one more photo from Lars: Someone had asked about the vegetation in the background of the video, it is a Japanese maple. Niels.
  9. Here is what Lars Jensen turned the blade into:
  10. This thread made me look when I first found this forum. It was January 2009 - 11 years ago! Back then and still today, I continue to be impressed how willing everyone is to share their knowledge and experience. It's truly unique. While my own progression has been somewhat slow with a few hours of blacksmithing here and there, I get a lot of joy and energy from seeing what others here are up to. I would totally go for a t-shirt. My general requirement for all t-shirts is that they need to be 100% cotton so that they can graduate to blacksmithing t-shirts once they wear out for regu
  11. Here is the final video. Let me know what you think!
  12. Yes, precisely. I can dial in my propane forge so that there is no excess oxygen or even run it with excess fuel, i.e. a reducing atmosphere. While I have never worked with an induction forge, I imagine most would run them in regular air with lots of oxygen around happy to create scale.
  13. Hi Dan, Particle Counters definitely seem like the the way to measure that. They are still very expensive, e.g. around $2000 for the cheapest version. Probably overkill for what I need. I like the non high tech method with the sampling tray. I will think about that.
  14. As you might know from my Youtube videos, I built myself a mighty metal dust collector. It seems to work alright but it made me wonder how I could test the quality of the air in my shop. I tried this laser illumination method: Has anyone here figured out how to measure the air quality in the shop?
  15. Dave, since you had an induction forge for ~8 years. What's your verdict? How often do you use it? What do you use it for? I would imagine that oxidization is probably much more prevalent unless you house it in some kind of noble gas.
