  1. Yeah, Alan said it already- the oxygen in the scale steals the carbon from the iron leaving behind more iron and producing more CO. There's no carbon in fire scale.
  2. I'm impressed you were able to hammer it up. It looks like on the verge of cast iron. A little sand and an occasional handful of firescale thrown into the remelt will help control the carbon.
  3. Also, even after roasting, it may still be non-magnetic yet still good to smelt. There may be some reduction during the roast and therefor some change in color.
  4. Forgive the fact that this isn't explicitly a topic on blades. I figured, however, that given the knowledge of many folks on this forum it might not be a poor place to ask. I've been commissioned to make a viking/norse style drinking horn stand from iron. I am wondering if anyone knows of where to look for historically accurate examples of such stands? Photos or otherwise that could be used for inspiration and/or replication. Many thanks, Eric
  5. I find this website to be more useful for finding locations as well as some information on past workings. The gps coordinates (at least in my area) are quite accurate: https://thediggings.com
  6. Has anyone had luck buying older tap and die sets on ebay? Is it a crap-shoot? Are there specific companies to look out for? Is it financially worth the effort? Thanks,
  7. Got a new blower, same model except an 03 instead of 04. That one worked well after adjusting the internal sensitivity adjustment on the blower. Glad to know about that little thing! Looks like that first one had issues all along.
  8. Hmmm... hopefully the cfm on the 116630 is high enough. Besides the lower max cfm the pressure/cfm graph compared to the 116643 are quite similar.
  9. Thanks for the response Skip. Nice to see this little diagram. I did find this little adjustment on the schematics and asked the company about it. I've tried playing with it and to no avail unfortunately. At this point I feel the problem is definitely in the electronics of the blower. I found another one on ebay that I ordered so when it arrives I can test to see if I get the same issue or not. It also seems like maybe a fuse is being tripped as once the blower cuts out it won't turn on again until I unplug and re-plug the main power to the blower. Skip: You say you used a bunch of the
  10. How much does the fly-press weigh do you think? Also, what sort of operations have you been able to do with that one? Thanks,
  11. Well, with the blue (low supposedly) connected to "OV" and red (high supposedly) connected to "0-10V" the blower actually does slow down from 10V down to about just under 7V. After that it just turns off... bad blower electronics? bad signal generator? I'm baffled.
  12. The higher output connect being "0-10v" i presume, right? This is what I feel too and it how it is set up in the second photo. I havn't tried moving the white line to the sig-generator. If that was the case which other wire would connect to the power cord for the blower?
  13. I tried hooking up the blower and I'm having trouble. I'm wondering if the blower's electronics are shot. The only way I can get the blower to run is in the first configuration. However, it only runs at full blast and the sig-gen dial does nothing until I turn it way down and then the blower cuts out and wont go on again until the power plug is turned on and off again. With the blue wire on "OV" andthered on "0-10v" the motor just starts to run and then cuts out. Something doesn't seem right. Thoughts?
  14. Well, I'm currently answering all my own questions. I should have thought about this harder I guess. I found an old laptop charger to give the generator power- worked like a charm- just stripped the wires. I called the company and found that my wires are: blue=command low, red-command high, white= neutral, and black=AC in HOT.
  15. Hi, I purchased a setup similar to J. Loose's. The catch is I know very little about wiring up electronics. Can anyone give me insight into how to hook this blower up? I understand that the signal generator needs it's own power supply, though it requires "dc12-24v". Does this need to be a DC adapter, for instance like this ? Or are the amps too high on that power supply? Likewise, I'm not sure which wires should hook up where, and my wire colors are different then those in the photo above. Thanks in advance for any help- hoping to learn.
