How do you forge this detail?

[fritzdecat]

I am referring to the little diamond shaped element underneath the scroll?

Maybe a set of dies under the airhammer? Hopefully there is another way

Any help appreciated. Thanks

There are a couple of ways:

1. Forge a triangle cross section that can be slipped over the parent stock size like a collar and forge weld in place.
2. Use a butcher in top and bottom dies (this shape "^") and make a groove in two places on all sides that leaves the diamond in the middle, then draw down each remaining side. I'd probably use this second method as it is more suited to a power hammer.

Hard to tell from the pic but could be done by either of two methods.
1.) It is a collar.
2.) It is upset and swaged. Take heat and isolate on either side by quenching then upset into a bulb. Use a swageblock and top swage to form the diamond.
That would be my guess if it ts not just a collar.Dan.

Looks like that section of the bar would be upset quite a bit, then forged carefully using the edges of the anvil while holding the bar at about 45 degrees. Would be a lot like forging a ball on the end of a bar, without all the forging down of the points. Except that the top and bottom angles would have to be carefully shaped. That's how I would go about it by just anvil and hammer.

Now, in a perfect world, with plenty of tools available, I think I would upset the section, and use a top and bottom swage to form the angles needed. Just keep turning the bar until the upset reaches the shape and size desired, and the taper back to the original size that you want.

That would be easiest way, in my still learning, quite the noobie opinion.

the third way which isnt forged is to grind a plate or bar to shape, drill a hole through the middle of it, plug weld it to the bar above or below, angle grind the other bar (quite a lot) weld it to the other bar and clean up the weld.

Id opt for the upset and swage

Thanks for the replies.

I am leaning to wards making triangular stock in the swage block

Then making a collar out of that material

When I am not banging and welding I like to fly model airplanes which coincidently use alot of balsa tri stock. Too bad we can't buy ready made steel tri stock...

Hey me too.

I think these guys got all the ways you could make that covered.

can't tell dimensionally what the base is but it looks like very thick square stock to begin with, having said that I remember a Steve Kayne quote "upsetting can be very upsetting"
Forge weld a collar and work to the triangular shape is how I would approach it. It also seems unlikely that the scroll is of the parent stock. One would need to feel it to imitate its construction but there have been enough suggestions put forth to start trying to duplicate it. Thats how we get better, do something even though we have barely an idea how it was done!

I admit I have cheated and used an arc welder and 4.5" grinder to make that detail.

It turned out well and nobody really knew how it was made.

Throw it back in the forge after you do the grinding so the grinding marks are oxidizided off and a few hammer blows will remove the evidence.

I trust nobody will insist I be removed from the site do to my impure work practices.
