That small video clip of the blacksmith trying to use a press to press what looked like a pointy tool into a workpiece sitting on an unsecured die, that he sprayed with WD40 I'm not sure why, and the press just kept moving then the press would, ofcourse, move it again, then he'd tap it back in place again over and over.
- cogogo 3y agoI know zero about being a blacksmith but that whole scene had me at a loss too.
- fein 3y agoIt looks like he got a drift stuck while trying to punch an eye into a piece of iron. His way of trying to free it is both mystifying and mildly infuriating. However this guy also turns functional items into useless decorative garden tools that no one will ever use, so it's not that surprising that he keeps trying to press a drift out with a sharp pointed tool that will never get a purchase on the work piece.
- simeonf 3y agoI'm still at the "making tongs from rebar" stage of my blacksmith career but I can probably explain somewhat: The machine is probably a power hammer. The pointy tool is a punch, used for making holes in the workpiece and often followed by a drift, used to widen and shape the hole. I understand some people use lubricants when drifting/punching hence the WD40. The v-shaped piece that is supposed to hold the workpiece is probably held there by a square shaft underneath that fits into a square hole on the work surface called a "hardy hole". It isn't unsecured ... but it doesn't seem to have a very fine fit so it moves a bit.
- cdchn 3y agoI know what he was trying to do - he was trying to move where he was making the hole so moving it was kind of pointless since the punch was just going to go into the same hole and move the base. And no, it wasn't in a hardy hole. It was just moving all over. If he didn't care where he was failing to make the hole it wouldn't have made sense to even try to move the die. You could see the punch going into the old hole even as he moved it over and just shift the whole thing. The WD40 is just going to flash off as well, there probably would have been better lubricants even used motor oil. Just seemed like a sloppy bit of work for what was such a lauded blacksmith.
- tejtm 3y agoThe over & over is just the video looping. The tapping is an attempt to position the workpiece under the "drift" The pointy cone is a "drift" should be to enlarge a existing hole in a hot piece of metal by pushing the drift through it, in this case it looked to be on a hydraulic press (too slow a stroke for a powerhammer) The spraying wd40 ... some just want to watch the world burn ... more seriously, the soot,oil & paraffin will act as a lubricant and discourage the tool from getting stuck (or welded) in the piece, although I must confess I have never witnessed the particular technique demonstrated in this flamboyant demonstration. In general, I see a lot less flying fire in the shop than seen on the tubes. Edit to suggest why; Like a hammer, the tool he seems to be working on has a handle and just as you need a hole in a hammer head to stick the handle in this tool needs a hole for a handle and the clip could be an early step in that process.
