  1. Nah,she's not the right kind,you need Bufa sonorum(now those make for interesting kissing...). Good work,Ibor,right on.
  2. Excellent,Kris,the Very essence of "traditional",that! A very interesting and valid reinforcement idea,Very cool. Could allow one to use that gorgeous WI,and not worry about any structural consequences at the same time.Lovely:)
  3. Why such complicated "spider" overlay around the poll?To reinforce it? And do the 3 different alloys represent the traditional construction detail/pattern? (any particular one?)
  4. Right on Kris!!!:) Beautiful steel,great going!:)
  5. Beautiful job,Will.Thank you for covering the process,and all updates.
  6. It IS,Alan,for sure... Frankly,i have a number of puzzling moments reading the description of their process... BUT,power to them,for sure,my blessings on Anyone trying to produce axes,my nit-picking criticism is neither here nor there... Darn it all,guys,my day-job is really catching up now,i've pried myself out of the forge,and will soon do a Cheshire Cat on the forum...:(...Though i still hold a glimmer of hope to ht some of the later forgings...(how i'd love to hang at least one,and swing it a time or two,but that's probably out of the question:()
  7. Tomahawks descent,in part,from what a guy may term "Biscay" pattern,as in around about Bay of Biscay,where iron was plenty and economy weak,so many cheaper trade-goods were obtained therein... Those were agrarian regions,with the type of wood-cutting chores amounting to the Slashing sort,clearing land,pruning fruit trees,and the like. (Although Basques do have some massive,thick/heavy/convex-bladed felling axes that they make to this day,and that they're famous for). So these smaller axes had a keen blade,thinning considerably in front of eye. It's pretty much a natural consequence of when you go to make a weld right there,forward of the eye,without you indulge in all sorts of specialized trickery to deliberately avoid that.. So yes,you're right,it's rather tomahawk-like in essentials.Trade-axish branch of that whole tree:)
  8. Totally,guys...I'm so happy you dig these crazy obscure documentaries! I can only sign under everything said above...My favorite scenes from Wira are also when he welds the blade on,and cuts it on the hardie the Same heat!:)...I also Really like that he takes that flat-stock,1/2"-ish stuff originally,and handles it in such a manner that after welding and largely shaping the eye,he Still had enough in the poll-end to suddenly forge it up over the anvil-edge into a decent,massy squared-off poll.... Yes,there's tons and Tons of most valuable data there,SO much to learn...Thanks,Alan,yes,those other guys are great too,also very important clues to SO much there...
  9. NOWHERE near as ugly as i still come up with on occasion,i'm tawdally with Alan-great job for your second attempt. On all else he says as well,that pesky pin-hole is a design flaw,and with given interrelationship of parts cannot be eradicated(till it's too late and it's all oxidised in there,but even then and even as a cold-shut;it's present in some historic examples). And mild to mild is evil,of course...AND using leaf-spring in and of itself is a constant challenge... Great beginning though,right on!!!
  10. Another very special video,on the different end of historical spectrum,though relatively close in time of filming(it pursues much more modern tradition, pattern,and purpose) . Both of these illustrate well the essence of handling that big of a forging.The amount of heat,the energy of men and machinery,the amount of technology involved,all speak of the sheer challenge of what it takes to forge a decent axe. The left-hand(for me,being right-handed),the tong-hand's work in these may be easy to underestimate at first glance,in actuality it is super challenging.So are many of the more subtle details... Forgive me if you're already well familiar with these...
  11. OK,here we go,i found it: The man in this video is thought to be Carl Frederik Dahlgren. One of the very best hands with a hammer of all times.Axes with his initials(as well as his brother A.B.)are still in use,and cherished by those privileged to've owned and used them. (these are carpenter's axes,not felling). C.F.Dahlgren has lived to be 91 years old.He was laid off many years, long before he died.He lived on a pittance that his son managed to send him,(his son had to leave Sweden where metalsmithing was collapsing and spent many years working at a factory in Russia).Letters exist where aging C.F. tearfully thanks his son for support. Those personal notes may not seem necessary,but to me they're a part of the entire picture of axe-forging...
  12. Joshua,whatever happens,don't let it discourage you... It Is cruel,and heartless,and Will make a better Zen buddhist out of you...But the result is commesurate. And it will try to kill you,or hurt you,and can.In theory,the heaviest stock a guy can forge by hand is 5/8" sq.Any larger(and the curve is exponential),and your blow no longer penetrates the entire depth of material,becoming a Riveting,vs a true Forging blow. Thus all the welding of diverse parts,also thus the interest in the pre-Industrial types,they were closer to human scale. I'm trying to think of the video material as per Mike's question(thank you,Mike,by the way,for your kind and generous remarks).When i Did watch video material,what most impressed me was one video i cannot find...:(..It is called Axe Manufacturing at Wira factory,1923,and if you can find it by chance,it's Extremely informative. Not in any Direct instructional manner,but in graphically informing one what energy it demands,and how to trick these too-large masses of steel into submission... An axe is one of the oldest tools,and was made at different times in a myriad ways...One of these ways and methods will be right for you,explore a few,there's Something out there....
  13. Yes,Alan,very much so. And a part of it is convexity(-ness?),it confuses the eye...AND many classier examples are wore down... The convexity is something of an enigma:Although a most ancient(indeed Natural) design feature,it was first exploited by Americans as a standard,integral part of design. By then smiths were happily grinding away on fairly efficient grind-wheels(most often obliterating traces of the process). Is convexity a function of forging or grinding?! Inasmuch as forging is concerned:Axe blade is too disproportionately flat to be forged on edge. All mass redestribution necessarily squeezes out top and bottom,into the kind of bulges that are rarely if ever seen on axes.Naturally,it can then be trimmed by a hot-cut....But was it done that way... (forgive my rather pointless musing...)
  14. The blade portion of the last axe is entirely too fat,and must be re-forged. It's a tricky deal,as the side-faces of the blade will form what in an axe serves as a de-facto chip-breaker. It's role is vital in the use of the tool,as it controls the amount of penetration into wood,while in the same time using an n-th fraction of the energy of the swing to break off the chip along the grain,and spew it out of the cut. That,besides doing the intended work,prevents the axe from wedging in the cut. Wedging action is uber counter-productive;it brakes the rythmic flow of the axman's work,necessitating a rearrangement of muscles used,and is just plain damned annoying...An experienced hand with an axe actually uses the free,easy rebound of the tool to momentary relax the involved musculature,making it possible to work for a long periods of time without getting wiped out. That became the iconic feature of an "American" pattern of axes in general;it was achieved by means of a correct convergence angle of the blade itself(disregarding the actual bevels of the sharpened edge). Also,the Convexity of the blade played a very important role.But the angle of the raised central portion is critical. Unfortunately,i'm a slower learner than most.And in this,the 7th attempt am back to the problem with the 1st-a lack of mass near the cutting edge...(i'm bracketing it:))...maybe 8th time will be the charm...no..don't sound right...well,maybe 88th?...:) I've only started grinding it,and not sure yet just how insufficient it'll end up being.Some photos of the above: In this next,a top-view photo,is a good lesson that i'm learning for these past two decades but apparently haven't learned yet:Drifting rudely and harshly near the finish stages,at insufficient heat,WILL open weld-seams. (there's actually more to that,but enough bs for one post...:)).
  15. Mike,this is a great question,and anything to do with JA's methods is enlightening to say the least,and Most appropriate in any discussion on axes. Unfortunately,i myself would be very interested in anyone else's opinion,as i haven't seen any...:( I've seen a few minutes of one older on on UTube,a bit where he welds the split-poll on the mandrell,but that's it...(my reception here is Tres lousy,and videos as a medium is above my pay-scale:))... also as a life-long reader they boggle me pea-brain,too much info...). A while back JA posted amazing,marvelous photo sequence on his blog about exploring this Norwegian pattern(he refers to it as a 5" carpenter's axe,it's Hjartum-like in essence). That was the last thing that i became aware of on his axe-front,and it is just Incredible...As-forged form he comes up with is simply outstanding...I could wholeheartedly recommend that(and much else on his blog),but sorry-no info on videos.
