  1. I have a 240V extension cord from my dryer outlet to my shop which is about 50' long. I don't recall the gauge of the wire (it came from a nuke plant which are rewired every few years just because) but it runs my rotary 3 phase converter made from a 5hp motor, a 60 gallon 6hp air compressor, a hypertherm plasma cutter and a Lincoln Idealarc 250 amp stick welder with no problem. However there is only one outlet in the shop so only one machine is run at a time. It has been this way for nearly 30 years with no problem. From the rotary phase converter, I run a lathe, milling machine and a large belt grinder but again, only one machine at a time as there is only one 3 phase outlet. I do have plans to upgrade the wiring and give the shop its own 100A panel which may actually happen this year.
  2. The Germans in WW2 used a thermo set plastic with wood chips in it for handgun grips and bayonet grips I believe. I have seen a similar product on current Czech produced firearms which looks very similar to what you have except it is a deep red color. This picture should give you an idea of what it looks like. Tough stuff I think.;
  3. I would make sure that the female part of the taper is clean. If there is a chip, a bit of rust or other debris in there it will never grip properly. (Do NOT put your finger in there and power the machine up - it will twist the finger right off your hand in less than the blink of an eye.) You can use steel wool or a scotch brite pad on a stick to get in there. The male part needs to be clean and free of rust as well. This you can clean with a fine stone if necessary. The Morse #2 taper is common on drill press spindles and you can purchase a #2 taper reamer to clean or freshen it up if required.
  4. It looks like a sword that was either broken or intentionally shortened to make a knife. I can imagine the guard was originally attached at the pommel as well and was a D guard sort of thing.
  5. I have cut many propane bottles with a torch and I'm still here. The older style bottles I would open the valve and leave outside in the sun upside down. Propane is heavier then air and will escape especially when the bottles are warmed by the sun. At night the bottle will cool and suck cool air in and the process is repeated the next day. After a few weeks or a month of this passive aspiration, I warm the bottle with a rosebud torch and after a bit I play the flame at the open valve. If it doesn't light, there is no propane left and I cut into it safely with the torch (or a grinder if that is what you have). The newer bottles have a valve with a three lobed valve handle or knob that require a fitting to be screwed into the valve to let the gas out. I scavanged a fitting with just a stub of the hose remaining off a gas grill from the curb for that purpose. The same process applies but you have to leave the scavanged fitting in until you have cut into it. A grinder spark or flame from a torch will ignite propane so the bottle has to be empty of flammable gas before you cut.

  7. It is like a large single tooth file. I have seen similar tools used to create fullers but nothing like this before. Who needs a belt grinder? https://www.youtube.com/watch?v=zNPc6xBBiLk
  8. My mother gifted me a slaw cutter years ago. It works like a large upside down wood plane - https://www.google.com/search?q=slaw+cutter&sxsrf=ACYBGNSOleNr3jScO6opP_J8sts9XCQ9Mg:1572621788561&source=lnms&tbm=isch&sa=X&ved=0ahUKEwie2srYqMnlAhXiUt8KHS8SCM0Q_AUIEygC&biw=1920&bih=937#imgrc=oFBHrgdVbv2PVM: While not a hand held knife, it is an efficient way to cut the cabbage for either slaw or sauerkraut.

    There are some youtube videos on how to convert your MIG welder to a TIG welder. Basically, you modify a MIG tip to accept a short tungsten electrode and do not use the wire feed function. I've never tried it but thought it an interesting hack.
  10. Years ago, I experimented with various non ferrous wires, bronze, copper, silver and brass by bundling them all together in a haphazard way, compressing them in a vise and then flooding with silver solder. I would then roll the lump out, saw cut and stack, solder again etc. but found that frequent annealing was required when I got near to the point of having a desired thickness sheet otherwise the silver solder would breakdown and crack. Made for some interesting looking bits that I used in jewelry. I never tried to forge it hot and tend to think it would not work so well.
  11. 1. Butcher shop - buy some soup bones, make some soup and then use a bandsaw to cut your slabs. There is a treatment procedure for animal bone that involves boiling in acid to remove soluble organics before bone is used for jewelry etc. Somebody lifted my book that described it though. 2. Pet store - You can buy bovine bones there that appear to have gone through the treatment. Again, a bandsaw is required. 3. Atlantic Coral Enterprise - giraffe, camel bone available. Wholesale operation with minimum purchase requirements. More bandsaw.
  12. It's free and you haven't taken it home yet? The motor may be able to be wired internally to 220VAC 3 phase then no problem running it with a VFD and your 220VAC shop voltage. It should be marked with required voltage(s) on the motor spec plate.
  13. Just a comment on old belts. I bought a big pile of the 1x42 belts years ago and put a new one on the grinder just the other day. The seam let go after about 1 minute of running leaving one end with what looked like a piece of tape. I scraped the mating surfaces with a 3 corner scraper and glued it back together with some superglue. It held up long enough for me to finish what I was doing and then some. So not a permanent fix but enabled me to get a little more use out of the belt.
  14. Forging wrought iron? Impressive the way the scale comes off ! I think it is sawdust they are throwing on it - I read that somewhere but forget why they did it. Those guys were all stone deaf by the time they reached 60, if they were lucky enough to get that far. And yes, the radiant heat from a bar that big must have intense.
