October 11, 201510 yr Hey everyone, I am not yet a 'smith, still working up things for a forge. Which should be finished this week hopefully... Anyhow, my question is this: has anyone ever made either a fullering tool or pein on a hammer that was asymmetrical? As in having one shoulder or radius of the pein sharper than the other, and more gently sloping to allow it to move the metal in mostly one direction only? This may be completely unnecessary, and if so, feel free to tell me lol... Just sat here this evening and thought it could be useful at times if it would work...
October 12, 201510 yr I'm not clear about what you mean by asymmetrical. Do you mean like a conic section? curved, wavy, ?A straight or cross pein draws steel in two directions like a wedge. Rather than moving it in 2 dimensions it moves it primarily in one.There are as many shaped dies as there are imaginations coming up with them.A drawing of what you have in mind would help. There is another tried and true old trick for experimenting with these things. Whittle one out of wood, just a model is fine and give it a try on clay. Modeling clay works a treat, you can even experiment with pattern development for billet welds.Frosty The Lucky.
October 12, 201510 yr Or perhaps like a french crosspeen? If you wanted a conical peen you could do quite a bit just by angling the hammer so one side goes deeper; perhaps easier with a straight peen; but I've done it to make curved pieces before.
October 12, 201510 yr IE: French Pattern cross pien. It may move material one way more than the other, but not by much. How you swing will have more of an effect me thinks.
October 12, 201510 yr I'm guessing here but I think the OP is asking about a straight peen that varies in radius from one side to the other - so you get more spread across the larger radius. Edited October 12, 201510 yr by HWooldridge
October 12, 201510 yr I just have differing hammers; my favorite is an old one where the peen looks almost like a 1" diameter rod was welded on. Using that and the anvil horn I can move a lot of metal!
October 12, 201510 yr Author I'm guessing here but I think the OP is asking about a straight peen that varies in radius from one side to the other - so you get more spread across the larger radius.Yes sir, that was my original thinking... Again, haven't had opportunity to test the theory, but I appreciate the discussion guys!
October 12, 201510 yr Author I suppose we'll when ya put it like that... It does kinda sound like putting the horse in the cart and trying to pull it to town by hand lol
October 13, 201510 yr When the question is has anyone ever made... the answer is almost always yes. Whether it was worth making is another matter.
October 13, 201510 yr Not to mention that I have reground a fuller on one side when there was a nasty chip there so I got a "combo die" effect. Didn't like it as much as my wide diameter fuller; but it could be that I just don't do a lot of a process that would profit from using it.

October 13, 201510 yr Luckily, I haven't encountered the Forbidden issue yet... Just a matter of time....
October 14, 201510 yr shaping corners and edges down in a recess require tools with odd shapes due to the angles and off-centre hammer blows and plenty of mental agility is also needed. Edited October 14, 201510 yr by yahoo2
November 29, 201510 yr I've seen power hammer tools somewhat like you're describing. As a matter of fact I went digging in my folder of E-books that I downloaded for free from google books and have already read (still a lot more to read) and found a perfect example. It is a side fuller, pictured in Forge Work by William Lewis Ilgen, on Pg 130, Fig 8. If you read the description below the picture, you fill find that it is usually used to isolate mass prior to drawing out so that a portion of the bar remains relatively undisturbed. PS: pardon the font, but the Sans Serif was making it hard to read the author's last name.
