Lou L Posted August 10, 2017 Share Posted August 10, 2017 All, I have tried to find information about texturing both sides of a leaf for a big project I am starting (mailbox post for my house) but I have come up empty. I decided to upload to the hive mind to solve my problem. I want the design to be visible from multiple sides and, this, would like my leaves to look "real" on both sides. This has proven difficult to do. When I add texture to one side I obviously damage the design on the other. I have tried using a stump as an anvil for the second side but I get fire, smoke and limited ooomph in striking. I've also tried scalloping the leaf in order to get some sort of shape into the other side but it still lacks life. I was wondering if anyone has done this and how they do it. Also, if one was to build a double sided die for doing this job how would they go about it? I have plenty of ideas but I want to download possible solutions from the hive mind (and maybe get some sense knocked into me for wanting to do this). Thanks, Lou Quote Link to comment Share on other sites More sharing options...
Daswulf Posted August 10, 2017 Share Posted August 10, 2017 I have thought about making a die for veining leaves as well. I swear I saw one somewhere but can't recall at the moment. If I were to make a die I would probably make it out of half inch or thicker steel into a spring fuller type design. Probably sketch it out on paper and cut out best I could to transfer in sharpie to the steel then use grinders and dremmel to carve the two reliefs. Thats just what I have been toying with in my mind. I'm interested to see others responses. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted August 10, 2017 Share Posted August 10, 2017 Do you have a screw or hydraulic press? Quote Link to comment Share on other sites More sharing options...
Judson Yaggy Posted August 11, 2017 Share Posted August 11, 2017 Clapper dies in a power hammer or press would be my method. Quote Link to comment Share on other sites More sharing options...
Lou L Posted August 11, 2017 Author Share Posted August 11, 2017 I forgot to add that I am without press...of any kind. I'm looking into a screw press option but need to get that huge shed so I have room for more stuff. Fortunately the shed doesn't fall into my hobby budget...it is a capital improvement my wife desires! I'm doing this with an anvil and am limited to making dies for the hardy or any other manual genius someone can come up with. Im interested in the idea of clapper dies nonetheless because I think the fabrication of them would open up door for me for other projects. I was wondering, do people have any success using dies that impress a positive image (with the negative carved into the die). Quote Link to comment Share on other sites More sharing options...
ausfire Posted August 11, 2017 Share Posted August 11, 2017 Interesting question, Lou. Most of the leaves I do are on wall hooks that back onto a wall, so only one side is visible. However, rose leaves are visible from both sides and I have tried to vein both. As you have noted, the first side suffers some damage from the forging of the reverse. I tried using a soft copper sheet underneath but with limited success. I did make one reasonable effort by making the first side very deeply textured and then lighter on the back, trying to avoid having one vein directly over the opposing one. Not an easy problem to solve, especially for smiths like us who are sans power hammers or presses! Interesting to read more replies. Quote Link to comment Share on other sites More sharing options...
JHCC Posted August 11, 2017 Share Posted August 11, 2017 Couple of thoughts: First, what kind of leaf are you thinking about? Something complicated with branching veins like an oak leaf or a maple leaf would be a very different matter from a willow or a ginkgo. Second, for tooling, I'd think about two sets of dies: one for creating top-and-bottom veins, and the other for fluting the edges of the leaves, like these: These could be either a set of a hardy tool and a hand-held top piece, or a one-piece tool (spring-loaded or guillotine) that sits in the hardy hole and leaves your other hand free to swing the hammer. Another option would be to forge as best you could hot, and then chase the details in cold, perhaps using a lead block as backing to keep from damaging the other side.

ThomasPowers Posted August 11, 2017 Share Posted August 11, 2017 I'd make one set of clapper dies that did the basic leaf and veining and then by using different preforms get some leaf variations and then do the curling by hand to make them all look different. Die striking is all about power, the more you have the more definition you can get. I'd try at least using a separate striker with a sledge if you are not getting what you want---or a treadle hammer!

Lou L Posted August 11, 2017 Author Share Posted August 11, 2017 I was just out in the shop trying my hand at the first experimental attempt. I happen to have a few 2.5 x 3.5 x 1.75 thick blocks of A36. I know it probably isn't tough enough for long term use but it's a lot easier to cold chisel and file. While working on a very basic leaf negative I came up with two ideas: 1). It's going to be hard to get good detail doing this alone and by hand (Thomas already knew this) but maybe, if I exaggerate the negative image, I can get enough. 2). Also, I might benefit from making one die concave and the other convex so that they mate perfectly. The convex die on top might increase the effectiveness for hand hammering....but it would definitely increase the complexity. I recently saw a video from Torbjorn Ahman in which he first forged/carved an item and then used it along with his power hammer (or press..I can't remember which he used) to create negative dies of the item. With that in mind, I was thinking another option to chiseling and carving negatives on both dies would be to carve or forge a positive of the leaf onto a piece of tool steel and then use it to hammer out the dies by hand. JHCC, Im still on to your idea as well. I am wondering if I can't take your idea and make a pair of beefy crimping tongs to work from the sides of the leaves to create the veins.

Lou L Posted August 11, 2017 Author Share Posted August 11, 2017 I just found a post by John McPherson from last year that offered some good insight for making a one-sided die. https://www.iforgeiron.com/topic/45798-raised-center-vein-in-leaf/?do=findComment&comment=474562 Quote Link to comment Share on other sites More sharing options...
Daswulf Posted August 11, 2017 Share Posted August 11, 2017 Scroll down and watch the video that nuge linked. I'm thinking something like this could be used hand hammering. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted August 11, 2017 Share Posted August 11, 2017 Some folks use angle iron to get a center rib; perhaps that would help as a preform for your dies to refine? Quote Link to comment Share on other sites More sharing options...
Frosty Posted August 11, 2017 Share Posted August 11, 2017 Do you have a welder Lou? If so. determine the amount of taper you want from the center vein to the edges. Shim 1/2 that dimension the outer edges of two pieces of flat stock and weld them edge to edge on a flat plate. Before you weld them you might wish to round the edges or shape the as desired. A SLIGHT taper might be in order if you want a distal taper in the center vein. Make two and chase in the branching veins. Make your spring and hardy shank. Align the top and bottom dies lay a piece of welding wire or similar in the center veins. Clamp and weld it together and adjust the spring as desired. That's it, I can make the thing faster than it took to come up with a decent description. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
metalmangeler Posted August 12, 2017 Share Posted August 12, 2017 The 2 methods I have used are a spring swedge, you will want to do your setup prior to using this tool as it will be only for your double texture not for the shape that comes from your setup. the other method and my favorite is to use a set of crown dies on the power hammer this could be hand done with a bottom fuller crowned both directions and a hand hammer that matches. again you will want to do the set up separately.

Okay, the really weird part is that the pickets he was making are almost exactly my design for my mailbox post except I have some branching at the top that encompasses the mail box. Thanks for the video. Lots of ideas here. Frosty, I seriously tried, I did....but I can't pick up what you are laying down! Seriously, I felt like I was doing a translation in my Attic Greek class when I didn't do the readings for homework. Just as back then, I still got some of it.... I do have a welder!

Frosty Posted August 12, 2017 Share Posted August 12, 2017 Yeah, the verbal description isn't very clear. I was visualizing the thing in my head and describing what MY dented brain was looking at. Good luck with following that eh? So, try this. Take two wooden rulers and lay them side by side, touching. Now slip something between them at one end. Tape them down, this is a model of one half what I was talking about. The contact point is at one end so the gap opens in a smooth taper to the spacer. The edge of the rulers are radiused (Oh okay, picture them radiused.) and make the central vein. The ruled marks make the lateral leaf veins. Now roll a wad of modeling clay into a cone and press it flat between the rulers. Turn it over, viola, Leaf! Is that better? Now do two out of steel and make a spring swage from them.

Lou L Posted August 12, 2017 Author Share Posted August 12, 2017 I can see it! I can see it! Thanks, Frosty. One more method goes on the list. Quote Link to comment Share on other sites More sharing options...
Lou L Posted August 15, 2017 Author Share Posted August 15, 2017 First attempt is nearly done. I haven't had lots of time in the shop due to...life. I tried making clapper dies for hand smashing. I cold chiseled, dremeled a little and then filed. It turns out the steel blocks I'm using aren't A36. They are low carbon high alloy for sure. I don't know if that's a bad problem or not...but they won't be seeing a power hammer. It took much longer to file than expected. The big, chunky orange sparks when I did a little grinding explained everything. Right now the dies are flat. A slight distal taper was filed in. I'm going to mount them in a housing without welding them to anything because I expect to have to make changes. They are lined up well (used my kids' Play Doh) but the vein patterns aren't identical. Shouldn't matter too much I don't think unless my leaves are examined by an OCD savant. Quote Link to comment Share on other sites More sharing options...
Frosty Posted August 20, 2017 Share Posted August 20, 2017 Sorry for the slow come back but I'd forgotten I had this in the shop. I made it to flatten angle iron without damaging the outside corner. It's made the same way I described except the sides don't angle away from contact. The edges in contact are radiuses slightly, less than a 1/8" radius but more wouldn't hurt. It's this large to work 1" angle iron and you can see how adding veins would make leaves. A version of this is what I was trying to describe for a spring die. Frosty The Lucky.

Lou L Posted August 20, 2017 Author Share Posted August 20, 2017 Thanks! That's pretty much what I pictured after explanation #2. I need to post an update on ng. So far version 1.0 was a failure...but I expected as much. The dies are pretty much flat and the piece walks around too much. I need to make it more concave and try again. Your idea looks like a nice way to bang them out fast. I'm thinking that using a narrow die on the top may impart a negative on the top of the leaf and a positive on the bottom. It wouldn't be the same on both sides but it would be two-sided and possibly more realistic. Thanks again for the input, Lou Quote Link to comment Share on other sites More sharing options...
Frosty Posted August 20, 2017 Share Posted August 20, 2017 My pleasure Lou, I've never made a 2 sided leaf die but grew up in a shop where punch presses were a daily chore, read part of my piece work job. Some parts had top and bottom dies and I've made a couple spring rope, dies for the power hammer. Achieving a representation of how a leaf thins from the central vein to the margins is the origin of my suggestion to shim the two "scales?" of the top and bottom dies. I'd practice with wood, hot glue and clay till I got what I wanted, then make the spring dies. You're welcome Lou, I live for this stuff, it makes me feel good. Frosty The Lucky.

ThomasPowers Posted August 20, 2017 Share Posted August 20, 2017 if you had enough power I could see a set of dies where you put square stock in on the corners in the main central vein and so index it for the squish---gives you more material to the sides as well. But it would need a lot of umph as it would be doing all the metal moving in the die. Quote Link to comment Share on other sites More sharing options...
Lou L Posted August 22, 2017 Author Share Posted August 22, 2017 I'm relative large and strong but I'm much smaller and weaker than I used to be. I wish I was blacksmithing 18 years ago when I could bench press 405#! Sadly, those days are long gone and now I'm content with being able to pick up my kids. My dream is to get myself in a position where I can sell enough projects in order to buy a hydraulic press. In my opinion a good press seems more useful than a power hammer. Point being....I don't have enough power. Right now I'm in the middle of two big projects and keep bouncing back and forth between the leaves and making a die for impressing a logo onto bottle openers. I'm stretched too far with the time I have. I just got an idea while typing! I may be able to si usage a bit of what you were describing, Thomas, by shaping the leaf blank like a diamond so it is really fat in the middle but tapered a lot so all the work doesn't have to happen with my hammer. Still, I need to make the dies more concave...as soon as I finish grinding/carving the dog logo for the bottle openers..... Quote Link to comment Share on other sites More sharing options...
metalmangeler Posted August 23, 2017 Share Posted August 23, 2017 You are describing your setup, as I stated earlier you will need to do a set up before you can use your swedge or the end shape will not look like a leaf. You need to make the tip and the stem before you texture the leaf or you will end up with textured piece that is not leaf shaped. I think you will find that just cutting your veins in with a chisel will be more realistic than using the grinder. If your setup is good and you should be able to do it quickly and easily on a round edge of your anvil or something like that you should not need any concavity in your die. You can test a setup by doing it then just pound the setup flat you should have a leaf shape just no texture. One of the problems people have making dies is they leave out steps they normally do in making a piece just making the last die in what should be a set of dies or tools, or in your case I think you might be trying to leave out steps you would do with your anvil when making leaves, just doing the last step with the die.

metalmangeler Posted August 23, 2017 Share Posted August 23, 2017 I typed this stuff last night then on the way to bed thought, this is not really likely to work. Thomas Powers mentioned the need for power, also with people hitting spring swedges by hand there is a tendency to not hit square, this makes the top die swing, likely smudging the result you are looking to achieve. You can avoid some of these problems by making a spring that needs to be opened to use i.e. you pry open the swedge to insert your work these will then suck out heat from the surface the very part you want to work or you could make a guided tool more time consuming to make. I mentioned earlier the other type I forge I really think they would be much more doable with hand held tools, I will be demonstrating at the local fair for awhile, if Frosty shows up with a camera I will forge one with that method he likely can put the pictures up here. It makes a different type leaf but making something that is achievable with what you have to work with is often better than having a good plan that you cannot do for some reason. (lack of controlled power, say the press or power hammer) Quote Link to comment Share on other sites More sharing options...
