    Very nice. That must have taken some thought to get all of that right. g

    Very cool, I'll be interested to see how it goes

    Coil spring

    Lots of questions. How hot are you getting the steel, what sort of oil, what makes you think they aren't hard? Without knowing what the steel is, there is no way to know what you should do with the steel. Coil spring is probably 5160, though it could be 1095, or 9250. I suppose that for a given application it might be case hardened mild steel, but that would be strange. Take a piece, heat it to non magnetic, and quench in water. Give it a smack with a hammer. It should shatter like glass. That is your first step. After that we can talk about process. Geoff

    Doing some "production" work

    What I find with this sort of thing it that I get faster doing it this way. It doesn't feed the inner smith quite as much, but I can get a lot done. I mix this with one off projects to keep from going mad. Geoff

    Doing some "production" work

    Well, it's more production than my usual style. I need some table stock for a Mountain Man show in a month or so. I'm going to make a bunch of small, rustic, rat tail knives. I should have enough stock left over to make a bunch of friction folders. I am not usually a fan of mystery steel, but in this case I know what this stuff is, it's 1095. The stock is old school plumbing tools, from the days when cast iron pipes were joined with lead, wax and oakum. I often make punches and other tools out of this stuff, but I wanted some small stock and this is a pretty easy way to get it on short notice. It's a bit chilly in the hot shop, and we have another big storm bearing down on us. I guess we should not have taunted winter. Each pic is one heat per piece of stock. The first pass was on the press, then the power hammer, which does a better job getting down to 1/4" thick and then a hand hammer. I'll do full tangs on these, and with what is left over, I'll make friction folders or some stick tang stuff. g
  6. You could build the mass heater with a foundation through the floor to the ground, the way a chimney in a post and beam construction works. The structure under the floor could be insulated from the burner, it just needs to support the weight. This sort of thing might be workable as well Geoff

    Best frontiersman steel?

    Tempering temps for 1095 and 5160 are not all that far apart, between 350 and 425 F. How hot would you need to be to cauterize an open wound? Somewhere between 150F and 200F is what my brief dip into the internet suggests. Geoff
  9. Here's the thing. If you live in a rural area with few rules about such things, a quality wood stove is a good idea. It costs time and effort and thought to maintain a good wood pile, but you're young (from your picture) and so have energy to spare. If, on the other hand, you live in a built up area, there may be laws which prevent you from burning when you'd like and a wood burner becomes more of an affectation than a real source of heat. In Seattle, for instance, we get temperature inversions, where cold air sits on top of the warmer air over the city. This often happens in the winter. When I was growing up, 60's and 70's it could get so bad that you could not see the mountains 25 miles away because of the wood smoke. Last year, when the whole west coast was on fire, the measured air quality in the Puget Sound during most of the summer was worse than Bejing. You pretty much can't heat with wood in King county without a certified stove with a catalytic converter on it. A well maintained, well operated stove has almost no smoke except at startup. OTOH, one of those old school cook stoves is not really that sort of thing. Another thing to think about, an open fire place will just pump the warm air right up the chimney, it actually makes the house colder, except right in front of it. Historically, people burned wood or charcoal or coal, because better fuels were too expensive, or too hard to get. And we denuded huge swaths of land to do it, like in Northern England. One answer is to build a system that uses trash wood, stick and twigs and mill ends and stuff, to make small but efficient burners. Look up designs for rocket stoves. In one system I was looking at they got 4 times the efficiency (measured in time to boil a measured amount of water per weight of fuel) over a traditional open grate system. And, because they burn much hotter, they produce much less smoke.' If you want to heat and cook over a wood fired system, I'm good with it. But do it because it makes real sense, not because it seems all primitive and stuff. I'll bet if you went back and offered your great grandfather the option not to spend half his life cutting and splitting and stacking and hauling wood, he would have jumped at the chance. Around here you needed 7-10 cords a year, cut, split, stacked and dry, every year. And that is in a climate that doesn't snow or freezing temps every year.
  10. These were in the possession of reseller of custom knives. A Fogg dagger and a gold mounted kiradashi. Typical Fogg touches, texture, gold, a fine touch. I didn't ask about prices, I heard him say that that dagger was north of $16 K, g

    It looked wrought to me, unless you are talking about the art pieces. Those are made from oil drums. The doors, which are the doors to an old coffee warehouse and roaster, all were clearly hammer wrought. The pintle hinges are forged and riveted from the back. There are no welds that I could see. Coffee wants shade, in Haiti they plant banana in the short term and avocado in the longer term. On my advice they are looking at one of the local (I don't know that native, but they are common) clumping bamboo's. Typica varieties grow tall and spindly and are subject to leaf rust. The Caturra, Catimore, and Mundo Nova sub strains are all low growing and bushy and are resistant to rust and are big producers. Geoff

    Cocoa grows low down, most coffee likes be high up. https://www.gardeningknowhow.com/houseplants/coffee/sprouting-coffee-seeds.htm Geoff

    Ah, the press. They are making concrete block. There are big brick yards like this one, and small ones where they turn out brick by hand in 1's and 2's. These pictures were a little dicey to get. They didn't want outsiders poking into their business, so Leo, our guide told them I worked for the company that made a new version of the press, and that I just wanted to see an old. Then we scooted out of there. g

    The graters are for de-hulling coffee. When coffee beans are ripe the have a "cherry" around the bean. The machine splits the cherry and and sends it one way and fresh beans go another. The beans are then washed, or, if they are using a natural process (like the Yemeni's do) the beans ferment for a day to 3-5 days and then are dried on concrete platforms in the sun. This is all hand work, then beans are spread and picked over, if it rains, the beans have to swept up and brought inside. The first stations are all pretty high, 4-6 k feet, and once the beans are dry they are bagged and hauled down to the small coops, and then into the city (Port-au-Prince) for more drying and sorting and roasting and shipping. Haiti was once the biggest coffee producer in the world, but earthquake, hurricane and corrupt governments have really cut into that. The town of Theotte is where we went to to see the farms, and we got to see and participate in every part of the process from planting seedlings (coffee tree live about 30 years, so you have to be planting new stock all of the time) to picking to de-hulling (You can see the back of the Lady Wife taking her turn at the crank) and then back down to the lowlands. As an indication of how difficult getting around in Haiti is the road up to Theotte, is 35 km long, it took us 6 hours each way in a Toyo Hilux. There are times of the year when the road is not passable at all. Haiti is a difficult place. There is no economy to speak of, there is a single "Western Style" resort up by Cap-Haitian, and we went to a town on the south coast that is kind of a Post Apocalyptic New Orleans, call Jacmel. Power is spotty, so refrigeration is hard to do, water is a difficulty in many places (we hauled 10 gallons up to Theotte) A hot shower is rare and valuable commodity. Everything in Haiti is built from concrete, because Haiti is mostly Limestone , and that is what they have. In some sense, Haiti is a model of unrestrained capitalism. The big towns are full of garbage (mostly plastic), the roads are brutal, traffic is chaotic. Pedestrians, bikes, motorcycles, small cars, small trucks, big trucks, are everywhere. Lanes are where you find them, , some times they are 2 or 3 cars across, lane direction is more of a suggestion than a hard fact. If you want to go to Haiti I can put you in touch with some people. Don't expect Haitians to speak English, so a guide is a good idea.
