  1. Saw this on Denver cl...........................''Very rare blacksmith bolt forming swage anvil. Has two interchangeable dies to form the shank, then form the bolt heads on the upper swage. Foot clamp to hold the dies. Very heavy, I estimate about 600lbs''.
  2. December 3 2014.....I don't like ladders much.........I needed to replace the burned out box fan I use to push warm air down in the winter so after taking the old one down (by a different rigging) I figured placing the new one atop my bridge beam prior to screwing it in to a rafter would be a good resting place for it and to rest the ladder on.....Bridge beams are supposed to roll......Ahah!......I'll anchor it to to the 1600lb power hammer anvil awaiting further fabrication, sound logic I thought.......Trouble was I when I set the beam where I wanted it I reasoned that setting a good firm tension between the load and the chain would be a good thing.....It was not. When I got to the top and put the new fan atop the beam I noticed the beam creeping AWAY from the ladder, I utter no, NO and started DOWN!!! I had about 8'' of ladder left on the beam and about half way down away I went......I landed on squarely on the layout table....The ladder jackknifed between my hyd bender and another beefy table, wrecking the $200 ladder but breaking my fall somewhat...It's been a long nine weeks since the wreck with frequent visits to the chiropractor and medication but all in all I was lucky not to have wound up in the hospital or worse :)
  3. Two words. Apple. Orange........If I want to cut a piece of hardened stock like and old file (un annealed) or thin tubing my choice is the chopper.......Cutting annealed tool steel for say a power hammer die the bandsaw shines and with my Roll In saw I can cut out shapes freehand.......For precise little pieces I've got a 10'' Wilton cold saw......I need em ALL but you may not.....
  4. My bolt on dies never come loose but I use a special compound.......It's called TORQUE......No lock washers,ever,
  5. After that 867 lb Monster you posted I was expecting something REALLY big when I clicked on ''5 foot anvil'' :lol: Still, that's a nice one old one in very nice condition......

Much to my surprise I wasn't writhing in pain......That was to come later, I pulled my hamstring, not too severely but it will be a problem for some time to come. All in all I feel lucky I'm not in the hospital or worse ;)
  7. Threaded schedule 80 is the way to go. You can order say 8'' nipples easily from Mcmaster Carr, part them in the middle and then you have two 4'' threaded units that are easily tapped for your mig tip(s)............. http://www.mcmaster.com/#4550K124
  8. The rattle can cold galvanizing paint will take a patina when treated with gun blue, presto black or any silinieum (sp) based compound used for patina and turn dark.
  9. Have you ever put an amp meter on it while it is running under full load? After charging the tank does the motor seem warm or is it HOT to the touch?
  10. This sounds like a big box store compressor to me...... they are notoriously underpowered and not made to last. What brand/model is it?
  11. Unless you BURN it, you won't. Zinc is pretty user friendly stuff and I've installed kitchen counter tops of zinc sheet, totally safe. That said, I sure wouldn't breathe fine particles of the stuff like when you buff it with scotchbrite or steel wool for extended periods. The worst dust I've encountered comes from bronze/brass, THAT will mess your lungs up big time and it doesn't take much. My father in law helped me once buffing/finishing silicon bronze and he refused to wear the dust masks I offered. He suffered for days but came through ok and was a believer after that.
  12. I've never seen the like......Perhaps a prototype that didn't go into production or what? With a guided spring arm it might be able to run fast, say 250+, maybe that's the reason for the guided spring arm? What size is it?
  13. Yes, this will occur. I always put a slight bend in my across my baseplates before I weld them, this will insure if it doesn't pull back flat at least there is a slight concave face down, which is far better than the reverse
  14. You don't need 8 bolts, two (per die) will do just fine if you nix the dovetail......never mind the tool holder in the foreground.
