  1. I often still feel like a newbie; especially in life Thanks for taking care of it, Alan!
  2. And it looks we made it to the other side. Enjoy uninterrupted programing for the rest of your weekend.
  3. Well, that stopped much quicker than I anticipated - I need to get that sorted first: You are running PHP version 7.3.33. You need PHP 7.4.0 or above (8.0.0 or above recommended). You should contact your hosting provider or system administrator to ask for an upgrade.
  4. I was showing a colleague recently how to forge kitchen knife. Here is the knife I came up with:
  5. Hi everyone! I will try to upgrade the forum to the newest version in about an hour, i.e. 9pm ET, 6pm PT. This will bring us up to date with the latest security patches. Assuming the forum comes back up; that's always in question with the updates. See you on the other side, NIels.
  6. You are completely right ;-) I did not try these on an anvil and the angle may be too steep. I managed to break one in the pritchel hole though. I had accidentally hardened it.
  7. Completely agreed @Joshua States - I was surprised how easy and quick they are to make. I was considering making a few more for my own use.
  8. That steel looks amazing. +1 to the flaming beard. That said with all you are doing here, there shouldn't be any hair left to burn ;-)
  9. I made these for a woodworking friend and decided to capture the process in video - @Alan Longmire gets a shoutout, too
  10. I am happy to report that Powerhammer and compressor assembly are back in working order and I can get back to some serious forge welding. Yay! While my shop was out of commission, I spent more time making EDM; my latest track is "What does it mean to be happy?" which seemed appropriate given the situation.
  11. As I could not help it, I captured the tragic rescue of the power hammer in video:
  12. Curiously, now my compressor assembly died. A nipple had corroded through. Argh! even with nipple extractors, I had to apply an enormous amount of leverage to get them out.
  13. Hehe. This one better last me at least ten years. It was interesting that I could not find a direct replacement. The original valve was 3/4in female npt on one side but the two piece side was 1/2in female npt. Quite odd.
  14. I am happy to report that I was finally able to source a fitting ball valve and got the power hammer working again.
  15. After I posted this, I looked for valves again and this one might actually be a fit. That said, I am not sold that this is really the problem and still need help :-)
  16. I am still stuck with this and getting really frustrated. Without a power hammer, a lot of things I used to do are just not feasible any more. I finally got the valve opened - it required a surprising amount of leverage for all pieces to get them to move. It's a two piece valve - but has an interesting inner screw to hold the delrin(?) washer in place against the ball valve. It's 3/4" FNPTxFNPT rated 2000 WOG and I have not been able to find anything like it. That said, there is minimal wear on the ball valve as well as on the screw. There is some play but it's pretty small. So, I am not sure if that's really the problem with this. If you know anyone who might be able to help, I would appreciate it. I'd be happy to pay for services rendered. At this point, I don't know what to do and I don't know anything about pneumatics :-( Thank you. Niels.
  17. Hi everyone, I have been using a Bull Hammer 75 for years. It's a great and simple pneumatic power hammer. Unfortunately, the ball valve that gets actuated by the throttle link is worn out and needs to be replaced/repaired. I suspect that the screw that engages the ball valve might be worn or possibly the groove in the ball or both. I am curious whether anyone here might know the manufacturer or may no where to get a compatible part. The interior dimension is 1/2" for the airway. The whole piece is ~2 5/8in long. I have been looking at two piece ball valves but have not found anything that matches the dimensions. As I can still make the power hammer work by adjusting the throttle link by hand, I have not taken it apart yet. If anyone here could point me in a direction towards repairing this, I would really appreciate it!!! Thank you, Niels For reference, here is an opened two piece ball valve - it's not a replacement but to get a sense of the workings:
  18. I actually grew up very close to Denmark. For the first few years in the US, I thought my accent would slowly soften and disappear. While the softening happened, I have given up on disappearance a long time ago :-)
  19. Sleep is important. I totally approve of it. Thank you for all your comments. I appreciate it. I have to admit I did not do a lot of planning when I forged the butcher. I figured I have enough mass in there that I can change the shape any way I like if the current one doesn't quite work out. As for the handle coming off, that's not my experience for the handled tools I have been using. We'll see!
  20. Not a single comment? Not even: Dude, this thing doesn't even have a real blade. Why are you posting this here?
  21. Can you share the letter or what they communicated to you directly? And presumably you have been selling only hand forged edged weapons?
  22. Here is the latest tool I built. Would love to hear what you would do differently:
  23. My contribution to the craft today was to finish this handled butcher.
  24. Here is another tool making video you might enjoy:
  25. You are all very funny :-) The wrought from the grain elevator is very high in phosphorous. Makes for great contrast but not so great for forging.
