Old fashioned ferrules

Can these also be done "backwards"? What I mean by that is start with a flat sheet and raise them into a ferrule? Are there any gotchas to watch out for doing them that way?

deker, I don't see why you couldn't make a male and female die and do them out of flat sheet metal. A piece of pipe and a smaller diameter solid bar would give you an idea if it would work or not.

I hadn't thought of doing it that way. I was thinking more along the lines of attaching a disk of material to the end of a mandrel using a screw and a small hole in the center of the disk and then forging the "washer" back around the mandrel. I couldn't figure out how to keep the edges from puckering. I guess if I used two dies and sort of stretched the sheet into the cup shaped die that might work (like how they make soda cans) that might work...hrmmm....

Theoretically, sinking them from a flat disc into a deep female die could work. The only things you'd have to watch out for are getting them stuck in the die or tearing through the disc... not sure if it would really be any easier.

Ok, I guess I am confused on how you did these. At first I thought you spun them and using friction and pressure, formed them into shape (as cymbols or brass instruments). Then I thought it was like press forming but reading that you started with tubes, I wondered how you got the holes so small without forge welding. Were these done cold?

As far as getting stuck in a female mold just use case lube for reloading ammunition. Many wildcat loads are either necked up or down in dies using the same principle.

Yes, they are done cold, (no spinning), just simple hollow ware raising techniques, with a mandrel and hammer...

Here’s one of the copper ones (the one in the pic with the smallest hole) I’m fitting up to a small blade. I cut the slot with some needle files, and then peened it in a bit over the mandrel, to tighten it back up.

I've never done "this" before.

Here’s one I fancied up a bit.

Really nice!
So...is this two rings and scrolls soldered on the ferrule? I see a confusing extra shadow on the top between the upper ring and the edge of the hammered dome. Is the dome also soldered to a cylinder?

Thanks!

Say What?

It's just two rings and three scrolls silver soldered to the 5/8ths ferrule.

... just some simple jewelry fabrication type stuff. Copper is a bit tricky to work with though, because it oxidizes and scales up so much. You have to clean it a lot to get the seams right.

I would really need to see this done. I think I have the idea but I cant figure out how you get them to turn out so good.
 
Wow!!
Your creativity is explosive and fits the concept of suprarationality.
Awesome-

Thanks guys!

I had fun with these. It was like working backwards... I usually start with the blade, but on these I started with the ferrules and handles. With silver being so high, I've been working more with copper. I'd been wanting to play around with some chip carving too.

As for sinking them in a die, you will need pressure pads. If you do not have the pressure pads wrinkles form, and you can only flatten the wrinkles, but never get them out.

You can see in the diagram on the right the material moving into a draw die.
