Just watched the cheesy fun movie “Axe Giant: The Wrath of Paul Bunyan”, which leads me to the question: Where exactly would you get a piece of steel big enough for a six-foot long axe head? Or for that matter now that guillotine blades aren’t routinely manufactured anymore, what’s the biggest cutting implement out there? Perhaps some piece of factory machinery used to chop something?
I’d go with a car shredder. There is no shortage of You Tube videos of these things in use.
Some sawmill blades are pretty danged big too.
And then, there’s always this. SFW. Some videos do contain profanity, but he’s cut that back quite a bit upon finding out that lots of children watch this channel.p.s. He's always taking suggestions for things to crush, etc. Don't suggest any kind of political items, however, because he won't do that even though he is Finnish.
In the James Bond movie “The World Is Not Enough”, they have gigantic circular blades mounted from helicopters for trimming trees in the mountains. I would imagine that those are real-life cutting tools and not just invented for the movie.
Oh my. The world is full of big ass shears. “Cincinnati, building your success by the ton”:
Quite a treat to stand beside one that is chopping a 1" plate 10’ long with a split second, “K-wham!!”
For the big axe blade you need a forge like a steam hammer. These guys are making one right now:Dennis
I forgot. If you want to make that axe blade in one press instead of using a drop hammer for an hour just bring it to Cleveland and use Alcoa’s 50,000 ton press:
This company to date has the record for the largest forged objects:
If you wanted a 607 ton axe head they could probably hook you up.
This. In addition to shearing machines, the manufacture of plywood involves “peeling” a log in a spiral fashion to create thin sheets of wood that are later glued together. See “veneer peeling blade.” Plywood sheets are typically 4’x8’, and I think you can even get 10’ sheets. So there are blades out there that are at least this long.
I’ve seen these in operation from about 50 yards distance. Quite impressive.
As for handhelds, talk to this guy (Michael “Irish Mike” Craughwell).
That’s talking abut casting 607 tons which, while impressive, is not the same as forging. The spokesman is quoted as saying, “The whole process from receiving drawings of the component, through pattern and mould making, casting, heat treatment, fettling and finish machining on a component of this scale is approximately 18 months.” No forging is mentioned. I would imagine they have a hammer or two lying around, though.
I tried googling “largest forged piece” and most of them talked about the large hammers and presses to make forgings, but not so much about the items made or their size. Oddly, one of the lead hits was a thread right here but it quickly devolved into talking about castings, including the Sheffield casting in your link, and never really answered the question. Looking on YouTube came up with this video of a German firm forging then machining a rather large generator shaft, which has to be close.
