  1. Hey gang, I'd like to point out a few things in a respectful manner: This fellow is typing in coherent English. That means he's in one of only a handful of countries globally. He calls out .25 1080. I am making an assumption, but I think he means inches, since .25 millimeter 1080 wouldn't be much good for most purposes. Only three countries in the world use the Imperial system - the United States, Myanmar, and Liberia. I don't think he's in Liberia or Burma. I could be wrong, but... 1080 is an AISI designation, the American Iron and Steel Institute. The rest of the world uses (not exclusively, but generally) other designations - BS, EN, DIN, JS, UNI. These three things help me to be comfortable in assuming he's in the United States, or at least North America, which alleviates most painful shipping issues. Is it really necessary for three people, at least one of whom says he knows the answer to the OP's question, to dogpile on this fellow? I feel that responses like this drive away users.
  2. Donated blood the other day, so I didn't have a whole lot of energy for forging, but I did noodle around in the scrap pile and weld up a halfway decent guillotine tool. The HAZ coloring makes it look a bit crooked, but everything is square, and there's a nice sliding fit to the dies, so this should be an improvement over my old clapper-style tool. Coat of paint coming tomorrow, and hopefully a test run as well.
  3. Wait, you mean I have to make stuff after I make the stuff to make the stuff? Sheesh, blacksmithing is a lot like work....
  4. Hi folks, here's a couple photos of the finished (but unhandled) flatter. I stopped by and visited a friend with a 2x72 belt grinder, which made fast work of dressing the face. The corners are slightly relieved to avoid getting "smileys" in my work, and the lion's share of the face is otherwise dead flat. I'm really pleased with how this came out for a first attempt. I'll drop in again when I get a handle on this.
  5. No mark, maybe the next one. I'm talking to Buckeye - I'm getting toward where I wouldnt mind so much telling people "I made that".
  6. Hi folks - I took Jenn's video as inspiration to get off my butt and back into the forge - I could use a flatter, but had been putting it off on the assumption that I needed a swage block to do the job. I didn't end up using my vise very much at all, though I can definitely see where it would have saved me time and some iterative shaping work at the anvil. Over two afternoons and about 4 hours, I came through to what you see here. The length of bar to start is, I think, very important, as it gives enough inertia to do a lot of upsetting without too much effort. I started with about 26 or 30 inches. I also used a 1/4" round punch to start my handle eye, and a tapered round drift to open the hole up. As I knocked the cheeks back in, the hole ovalized relatively nicely. The thinner cheek sections also made it easy to make some small adjustments to get the face of the flatter perpendicular to the "tail". I know this is a bit on the crunchy and lumpy side, but my first piece always is. A few days in vinegar and a wire wheel will help some... The next one will come out better with the lessons learned.
  7. The limited demo work I've done, the only rule was No Welding, due to the proximity of the crowd and the little tykes whos eyes are at the same height as the anvil... Similar thing goes for scrubbing off hot scale - be mindful of where that stuff is going.. Some places will set up lexan barriers, which might allow for welding, though it wouldn't be terribly historical looking. Other recommendations are to stick to simple items that don't take very long to forge, and that you can do reasonably well while distracted and answering questions. I've found it useful to have one item already completed, and one piece of parent stock propped up and available to hand out so people can see where you started, and where you're going to finish up in case they don't stick around. This is especially helpful for things that take more than a half dozen heats to make.
  8. Frosty, how many of these 3/4" burners can you reasonably run off a BBQ tank before it just freezes solid? I browsed through the thread, and may have missed a nugget somewhere, so I apologize if that's the case. I'd like to build a bank of 5 burners with a spreader plate or a shroud to make a wheeled weed-killer, like this one: These things retail for a gazillion bucks for what they are, and I figure I can fabricate something just about as good, and your T-burner seems like just the ticket.
  9. Well, it’s been awhile, but that’s how it goes, no? Here’s where I’ve gotten so far: Made some test cores and showed them to the foundry – they gave them the thumbs up, so that’s a positive thing for sure. I still need to make some more core boxes, but it’s not too hard. Below is the test pattern I’m going to try at the foundry – no edge features, just cores. This will help us learn about gating and fill, as well as whether our cores are sturdy enough. I’ve also gone and simplified the final pattern somewhat, and it may still not be done yet. Major changes include the omission of some smaller edge features, and the incorporation of a tapered socket for a Pexto stake – a popular request from a number of folks. The elliptical core went away, as no-one could figure out what it would be good for, and I chopped a few of the smallest round cores, as they can be easily enough drilled at a later date.
  10. As it happens, I do have the equipment, but not the dimensions. Still seeking the dimensions of the locking pin from anyone who might have one. Thanks all.
  11. That's a fair question, and the factory is the first place I went. They want 53 dollars. That's entirely too much money for a 4" or so steel pin with an eccentric turned on one end.
  12. Hi folks, I recently picked up a Di-Acro 1A bender in nice shape, but missing its locking pin, the one with the eccentric on the bottom to clamp in your stock when you start the bend. Does anyone have one of these that they could take some dimensions off of? Specifically, what the large diameter is, and what the offset of the eccentric pin is? Napkin-CAD or a pic and some notes would do the trick.
  13. What dictates when a forging is finished and who inspired you? TL,DR: "Finished” varies based on the service of the item, and its exposure/surroundings. Minimal tooling smiths like Petrila, Ross, Aspery, Brazeal, Ahman, Taylor are inspiring. I have more or less always considered myself a bit of a hack. I think this stems in large part from having been raised by perfectionists, one an amateur cabinetmaker, and the other a retired machinist. It’s daunting to look at some of the things you see made by experienced people at the peak of their skill, and it’s easy to think that you’ll never be able to get to that level of quality. The tooling and fixturing required (or at least collected) can make your head spin too (I can’t do that job without this special $$$ widget…) Having been educated as an engineer can be also be ruinous, because you spend years learning how things fail, and spend a lot of time learning how to strip away what isn’t required in a design for strength and utility, and then adding back things to meet various codes and criteria that aren’t necessarily driven solely by function. Also, little or no attention is given to form. Function is mandatory, followed by cost and manufacturability, and form is a distant third concern. This is not to say that a spare, utilitarian design cannot be beautiful, it can. It just doesn’t often happen. So, anyway, I did become a marginally competent metal and woodworker, though I am no toolroom machinist, nor cabinetmaker. I never will be either, as that’s not my trade. Blacksmithing, though, is not something that I grew up with. I did see a lot of wrought iron growing up outside of NYC, and in various museums. What excites me about wrought work is that depending on the job, the finish level varies greatly, and so does the skill level required. There is a banded chest in the Chicago art museum from the 1500’s that looks just terrible. But, for the job it needed to do, someone thought it was finished. Seeing something like this venerated in an art museum is encouraging to a lot of newer smiths. You think, “I could make that.” And you’re probably right. It doesn’t take too much practice to make a decently fair curve, and penny scrolls and leaves aren’t too onerous either. Now skip ahead a few centuries to the 17th. Same Chicago Museum. This work is inconceivable. Forged, filed, sawn, engraved, pierced, sanded, polished. Oh, and a ton of springs and small items heat treated, then polished. This isn’t a door lock, it’s a functional sculpture made by someone(s) who did nothing else. I’ll never get here. Not only could I not get to this level, I don’t care to. I can’t devote enough hours over a long enough period of time to learn how to do this level of work competently. Additionally, there are probably only a handful of people on the Earth who would pay someone a living wage to make something like this. What I’m saying is, this is not something that should be held up as the ideal standard for a forged product in the 21st century. Here’s a staircase and a pair of grilles (same museum; can you tell I’ve been to Chicago recently?) Late 19th-early 20th centuries. Though under some paint, you can tell that they’re all hand made, and well. You can see no two pairs of the components are exactly alike, but this is up close. From the intended viewing distance of several feet, you cannot tell. The parts form a pleasing whole, and any flaws disappear. The white grille spent its life outside, and you can see some signs of that. The black grille and the staircase, though, they’re inside, and always have been, so they look as they did when they left the shop. You can see the welds on the stair rail scrolls, and you can also see the differences from element to element, probably as they were tweaked to fill the available cell at final fit-up and assembly. I think that’s OK, though. The slight irregularities, as viewed by the user, form a more organic form, giving some life to the metal. Look at a grille that was laser cut sometime with what should be an organic pattern to it. Unless done quite well, you’ll feel something isn’t quite right. It’s static, no sense of movement… These are items that I, a first-year learning smith, do not have the ability to make right now. But, I think I could make them with a bit of practice and a little bit more learning. This level of fit and finish is accessible by the mere mortal backyard tinkerer, without massive tooling and expense, nor a lifetime of practice. Some patience and planning, to be sure. I think this level of work is pretty close to optimal in terms of finish and consistency. It is "good enough". Recall that in Islamic art, for example, it considered an affront to make a perfect pattern. Signs of the human hand and imperfections are included deliberately by the artist. I guess one of the points I’m trying to make, is that “finished” is subjective and qualitative. All the things pictured here were bought and paid for, by presumably happy customers, and have been appreciated for centuries. Different things, different jobs, different standards. All finished, though. For me personally, as a blacksmith, the items that I find most inspirational are the ones that are “accessible” in the sense that I can understand how they were made, and that “I” could make them, with a reasonable amount of time and patience. Your work, Peter Ross’, Mark Apery’s, Brian Brazeal's, Torbjorn Ahman's, and Rowan Taylor's are very inspirational. You’re all working at a very high level of skill, but there is no really good reason preventing me from working at the same level of quality if I choose to put in the time. Also heartening to the beginning smith is the fact that most of the listed smiths do amazing work with a minimal number of tools; very important to the person just getting going. In the meantime, at my own skill level, I can make useful things, though they will have scale marks and errant hammer dings. For most common forged items, it’s not like a machined part where it’s within tolerance or it is scrap. There's a lot more leeway if you're willing to accept less than perfection in your own work. I'll also accidentally produce something nice looking from time to time as I learn and improve... Regarding your door handles, the large one would be splendid on the front door of a colonial Cape, and the small one would be very appropriate on an outbuilding, or a less visible door or cabinet. You know, pride of place, commensurate with skill required and effort invested. That Suffolk latch just wouldn't make any sense on a chicken coop or a toolshed, even if you were unusually wealthy. As for the hammers, there isn’t any reason in the world Big Blu (and other manufacturers…) couldn’t have used a flatter on the finishing pass and cleaned up the vast majority of the tooling marks. I don’t find it appealing; it looks unfinished to me. Other people will go out of their way to seek out such a finish. No accounting for taste. That said though, I forged a hold-fast for the spare tire under a friend’s car. It’s not pretty, it’s not filed, it’s not painted. It’s covered in fire scale. But, nobody is likely to see it between now and when it gets chewed up to be made into a new car. I thought it was an appropriate level of finish for the job and exposure (and compensation: none).
  14. Alright, this is what's coming with me to the foundry tonight to chat with the professionals: I added another half hex, another hole, an oval, and re-arranged everything in the block one more time, just for fun. The hex sizes changed at someone's recommendation to correspond to sensible sizes across the flats for tuning up bolt heads if desired. The oval I added just because I could, thinking it might be useful, but I really have no idea other than for drifting open quite large things. I'm still happy to take suggestions for cores.
  15. JME1149, do you mean like on the Yater block? I am considering something like that, but don't know what you'd use it for. On the Yater blocks, I think there is a reason that they all seem to have the original yellow mailing address from Wally still in those areas... What do you have in mind for a use scenario? I did deliberately leave the small 2" flat on one edge so that a smith could file in something like that, but on a small scale, for forming a bottom die to do a reinforcing rib, like you see under spatula ends and such. Possibly also a little veining type die could be filed/ground in for doing collar stock with roping/beading. I don't think I can cast something that fine that wouldn't get obliterated in further finishing. DasWulf, holes added. Room for one more....
