  1. Thanks for the info, I don't want to bring the mods down on me. But what a fantastic haul!!! the step pulley alone would cost over $25.
  2. All, Sorry if I broke the rule listing the name of the sales agent I thought that the name of the agent w/o the URL would be acceptable but I guess I should l brush up on the rules before posting.
  3. Good Morning All, I wanted to ask if anyone has seen this type of shredder before. I picked it and a few other goodies up at an auction in Fayetteville TN. The motor is a 1/2 HP Dayton with a 4 step pulley and the shredder part looks to have been used to shred foam rubber. Motor w/ pulley and some kind of shredder thing $10.00 14" Plane $12.00 2 Electric start propane torch (TS3000KC and TS4000T) with full MAPP Pro and to part full real MAPP gas bottles $16.00 It was a very good haul. This same place (xxxxxxxxxxxxxxxxxxxxxxxxxxx) had a 137 (might have included the stump in that weight) Antique M&H Armitage Mouse Hole Anvil that went for $260.00!!! (I did not have enough extra $$ to bid but that is a good deal) This was an online action so you get the chance to get a good deal w/o having to be there.
  4. I think the fact that you have 2 at each foot is the best part since they will lever against each other and hold for a very long time.
  5. Mr. Thomas makes a very good point. There may not be a "safe" level of beryllium that once can take in without ill effects but the fact of the matter is someone may be exposed to a small amount of something and feel a little bit "off" and think that it was no big deal. There are a number of chemicals like lithium carbonate that have a VERY narrow therapeutic range meaning the "goldilocks zone" of do nothing, improve health and become toxic. If anything else I am always reminded of the words of Paracelsus (Philippus Aureolus Theophrastus Bombastus von Hohenheim) "The dose makes the poison" (Latin: sola dosis facit venenum). The fact that people are sickened by fatal water intoxication proves the point.
  6. Good Morning All, Please correct me if I am wrong in my understanding of the process used to make this bloom in to a blade. As I understand it the sword smith or any other type of smith would take the bloom and flatten, fold, weld and repeat. What I think I understand about this process is that all the smith is trying to work all of the crud (for lack of a better term) that is not iron out of the material using the process of flattening, folding and welding. I assume the mechanic that makes this work would be due to the fact that the aforementioned crud is brittle and would not weld due to being an incompatible alloy. On a side note I assume you could braze slag to steel or iron but that is not the same as welding. How am I doing on my understanding? Nice work.
  7. Copper + Arsenic is called arsenical bronze and as far as I know was once of the first types of bronze. A good copper/tin bronze can be harder than wrought iron or (I guess) very low carbon mild steel. The problem in the Bronze Age was that a given Kingdom might have copper mines but not many tin mines. Iron was not a hard (or I have read in history books called not a strong) as good bronze BUT if you found iron ore you did not need another metal like tin. As far as I know all bronze items start as a casting and then can be work hardened after that. Also the reason you don't find many old broken bronze swords at Bronze Age sites is a broken bronze anything could be re-melted and re-cast.
  8. I have a bunch of new blades I picked up on clearance at WalMart so these would not have the had the very hard life of a used blade. I almost want to take one and harden it just to see how brittle it gets. I would think these would be good for large bush knives or machetes. In these cases you need a blade that can bounce back from things but you should not expect it to hold a razor edge. I have some used bush hog blades like you see the highway crews use. I would think these blades a maze of micro fractures and metal fatigue.
  9. Never mind, I did not know Chromium had such a high melting point. I (incorrectly) assumed that some Chromium could out-gas. given the fact that it melts (from what I have seen) about 1,000 degrees Fahrenheit hotter than steel I see that I did not know what I was talking about.
  10. Steve, Thanks for the info. I guess the alloy is only a big risk if you try and melt the steel. Mo lib de num. I call it Molly also. thanks
  11. Good Morning All, I have been watching some videos on what must be the Darwin Comedy network A.K.A YouTube and I see people modifying air punches and chisels I wonder how much hexavalent chromium they are being exposed to. I know that there are small hand rivet tool sets that may be for hot rivets but a good number of the run of the mill air tooling seems to be chrome molybdenum steel. I was watching a video where the guy from Christ Centered Ironworks was turning a chisel in to a ball end tool once he got it up to forging heat. I have read on IFI that heating up a vanadium chrome wrench to forging temp is at best a VERY bad idea so I figured that was also true for chrome molybdenum steel. (Off topic, does anyone else here have trouble pronouncing the word "molybdenum"?) Please let me know what you think because if I am wrong I would like to know since it seems like a neat way to get some work done. If I am correct in thinking this might be a bad idea I figure you can take an air tool and cut off the tool end attach a "working end" that is a less toxic steel like 1080 or 5160. Thanks again and please remind people that just because it worked on YouTube falls in to the same bucket as "I saw it on HG TV so we should be able to do it". Ernest
  12. That might be the super-duty option and may test out at 3+ HP.
