    Ausfire, any waiter in the US can answer that. "What is the difference between an Australian and a canoe? Sometimes a canoe will tip."
  2. It followed me home

    From my readings on the subject, rust and freezing temps are the bane of the "bosh" tank, letting the water level get too low can burn up the nozzle, or cause steam explosions spraying the smith with scalding water.
  3. Tanks for high pressure welding gases, even BBQ propane tanks, are HSLA steels. High Strength, Low Alloy, very high purity batches of steel made just for the purpose. Think Kobe beef as a price point. They have to last a long time under less than ideal conditions, and I still regularly see tanks with swastikas, or Property of War Dept. markings. (WD in a shield) Very different to weld on than A36 structural steel, which is the Spam equivalent. Or 3rd world rebar, which is Alpo.

    Fore and aft hardie holes were a standard item: you will note that almost half of the production patterns had them. And of course, customs orders were always possible.
  5. Salvaging Sandpaper

    Foot square piece of hard fiberboard or plywood + spray can of adhesive + sandpaper = flat surface for truing up surfaces. Heat will usually soften the adhesive enough to easily change the paper.
  6. America has lots of track, and every time somebody replaces 1 mile of track, 10,000 spikes are scrapped along with two miles of rail. Somebody is legally recycling all that metal. Find out who does in your area.
  7. ID Anvil?

    NOT a welding line, a join between two wooden preforms in making the mold, that they did not even bother to blend in. To me, it screams cheap knock-off, after-hours work at a foundry with whatever was left in the ladle. And every town big enough to have a stop light used to have a foundry. No name = no liability. But what do I know, I'm just some guy on the internet, telling you something that you really don't want to hear.
  8. ID Anvil?

    Judging from the shape of the horn and heel, the thickness of the feet, and the pattern of the chipping along the edges and around the hardy hole: 99.99% certain that it is a cast iron boat anchor. Even if you got it for free, four hours in a car and a tank of gas later it would be a loss. Get a lump of steel from a scrap yard and don't look back.
  9. Type of anvil

    "The Mousehole Forge" , (2003) by Richard Postman, also the author of "Anvils in America".
  10. First post vice!! ID???

    OK, I'll bite. What makes you think any part of your vise is special? What are you seeing that we are not? Looks pretty generic from what I can see. Detailed pictures and explanation would be helpful.
  11. Post Vise Clean-up

    Very good info, David. The screw box alone was half the price of a new small vise. What year is that catalog page from?
  12. Freezing Propane Tanks. A Different Solution

    Heck, I can freeze up a bottle in August in the south! With no shade! You just need a plastic or metal tub a few inches wider than the tank. Propane tank does not need to float, in fact it should not. Filling it with a couple of gallons of cold tap water will work, does not need to be heated. Anything above 32F is fine. Just dump the tub when you are done for the day. (Skeeters in the summer, ice splitting the tub in the winter.)

    My inference from the website is that it is a salt bath surface nitriding and heat treatment, about like the coating on drill bits. Once your wear thru the coating, performance is no better than the base metal heat treatment provides.

    I became a shape-shifter when I got Furniture Disease. My chest fell into my drawers.
  15. 1936 fisher 250 lbs anvil

    Frosty, it looks to me like a poor casting run as far as surface finish goes on all of the body, especially the markings. It was the Depression, and there was no fettling done on that anvil past the striking surfaces. I speculate that the numbers were so illegible that they had to grind just that area, then stamp the date in for the warranty to be in effect. If you look at vises and other tools from the companies that managed to stay in business until WWII, there was a noticeable degradation in aesthetics, fit and finish on most utilitarian items. The heyday of ornate metalwork and metal tools was probably around 1890, and there was a downslope than turned into a sheer cliff in 1929. My $0.02. Which, like all opinions is worth what you paid for it. Maybe less.
