Forging Fun- Hasta tip
#1
Avete omnes,

BOY is forging steel fun! I suppose I might not say that were I a real blacksmith making horseshoes and other mundane things all day, but luckily I'm a new hobby smith, and my first piece is this replica hasta tip- after an original I have a photo of. I'm not exactly sure where it was found, but one of the same shape is in the Museum of Scotland. I'm not 100% sure if the size is just right (overall length 54cm [21 1/4"]), as all I could do to figure that out was to enlarge the image until the socket size seemed sufficiently large for the haft not to be too weak at that point.

An original piece that I believe is in Kalkreise has a section of haft still in place that shows it to be a larger diameter than the socket, tapering a few cm from the socket base. Since I had a section of 3.2cm diameter dowel from my old Vexillum lying around, I decided that would be a half-decent haft diameter and worked out how wide the socket end would have to be from that.

It ended-up being almost like a half-gladius on a stick :lol: but then the images of real hastae seem to show a very wide range of sizes (although virtually all retain the leaf-shape). So this one would be a thrusting pole arm as opposed to a light throwing weapon.

I began with a bar of mild steel (probably closest to Roman steel metallurgically) that was 5cm wide by 6.5cm thick (2"x1/4") and cut it to a basic leaf shape (accounting for the spreading as I flattened out the blade), and got heating and hammering. It has a diamond cross section just like the original, and I flattened out the section that would become the socket to a thickness of about 1.25mm. I then curled the edges of the socket around and after a lot of adjusting to get the edges to meet without a lot of ripples (I need a form), voila- now I can take on barbarians at a range of about 2.5m (8'). Big Grin It still needs a bit of work to clean up the last few hammering dents (the dark spots), and to polish out the sander marks (I used an angle grider with a sanding disc to get a lot of the scale off), but after an hour with some emery cloth I'm confident it'll look like a hastus tip polished daily to keep the rust off.

This makes me really want to try making my very own pompeiiensis gladius or maybe a pugio...

what kind of steel did you choose for this project? you use a gas, charcoal, or coal for fuel? do you got a nice anvil? :wink: i wonder how one keeps things from getting pitted whild forgeing, i still haven't figured it out...

anyways nice work, enjoy your new hasta.

Nice work!!

If this is your 1st project I can not wait to see your 10th project. Heck, I'd consider buying this one if it were offered up for sale.

Cheers!!

Just regular mild steel- <0.15% carbon I think is the norm. I used an MPS torch and a few fire bricks to keep the heat around the steel- it took a while to make the basic shape, but it worked nicely. And yes, I have a 50lb anvil- an indispensible tool...

And thanks for the compliments guys Big Grin

I'm not a blacksmith either, but at a rough guess I would suggest that the pitting might be caused by slag in the metal, which has been knocked out during the forging process. I used to sometimes watch an old blacksmith work and one thing which really struck me was how long he would work the steel before he began to shape it. He always worked on two pieces at once, so that he could work on one whilst re-heating the other in the forge (he used the explain to me frequently that this was where the term 'to have another iron in the fire' came from. He would normally work a piece of steel for about two minutes with the hammer and anvil before retuning it to the forge to re-heat. He would then take the other out and begin to work that instead. He would typically work a piece four or five times before he actually began to shape it and the shaping often took quite a short time compared to the work previously done. As he was working the metal prior to shaping quite a lot of slag would fall to the ground, but if I remember rightly, this did not happen to any great degree until the piece was on its second or third working. Obviously any pits in the metal caused by the ejection of slag would be beaten out by the repeated heating and hammering on the anvil. If I learned anything about iron working whilst watching him, it was that a piece of steel had to be brought up to the right condition before it could begin to be formed into whatever it was intended to be.

I hope that helps. By the way, don't take this as criticism of your efforts - I'm truly impressed with what you have managed to achieve on your first attempt. Well done!

Thanks for the suggestion Crispus, but it's actualy a lot simpler- I used a heavy hammer with a rounded face to more easily spread the steel (this was a test piece), and this left a 'dented' surface. Grinding down the face to smooth and clean it left the deepest points of the dents looking like separate dots. What you would have seen coming off pieces being worked by the blacksmith wasn't slag in the metal but rather the oxide layers that quickly form on the surface when hot steel meets the air as it's removed from the heat. There wouldn't actually be any slag in the metal, that's removed during the manufacturing process- modern steel is quite pure and very strictly-controlled in quality.

yeah, to get some good old wrought iron either you gotta dig through old old scrap or find a good source of ore and smelt it yourself. i wish the minnesota ore range's rich ore hadn't beed depleted in ww2 otherwise i'd be making wrought iron out back right now, all thats left is taconite now. not only is wrought iron not burn in the fire, it self fluxes for welding and is corrosion resistant...

man, i wish ore grew on trees...
