My raising hammer, 300 gm, came either from All Craft or Metalliferous in NYC. Most of my other hammers came from Metalliferous. My goldsmith teacher altered my raising hammer when I was beginning to learn. Being a novice, I didn't know what he did but I suspect that he took the corners down and softened the edges from harder angles. I frequently take brand new and antique hammers to the grinding wheel to get shapes more to my liking. I use older reshaped hammers as stakes for special work.
What I like about copper is work hardening. You hammer it from the top, it stiffens up. Then you hammer it from the side, and the top won't bulge as much as it would with softer copper. With thin mild steel it seems like a never ending story. Hit it from the top, hit it from the bottom, 80% of your bend springs back.
I can't be sure why this popped up in my recommended list but I can be sure that I find it to be truly amazing to watch. Just one question if I may. As are tamping your products into shape, how do you avoid stretching it so thin that it penetrates?
The metal is being moved not thinned, I start with a 20 gauge disk and when the beaker is finished it is still 20 gauge no matter where you measure. It may tend to get a little thicker at the rim but that's not been the case for me and most silversmiths. The cross peen hammer is moving the metal up as the diameter of the piece diminishes. Sometimes it does feel like magic. Thanks for watching.
@@Ceropegia Wow. Thanks. That also looks like magic. In the Episode . . . Start by Sinking, at the 1:33 mark, you state: "What I'll be doing is stretching the metal by striking from the outside . . . " From my somewhat limited knowledge of metal work, I'm not sure how you can be stretching the metal without making it thinner. But I will take your word for it. Cheers
Thanks for these vids. They are very satisfying to watch. I'm wondering though, wouldn't it make it a lot easier if you just made the beaker base the same size as the stake?
hi sage. thanks for the videos. i have a qustion: do you neal agaun after the second raising or any other time along the process beside the first time? tanks
The copper does not get thin as it it raised when properly raised. I usually use 18 gauge copper for large pieces and 20 for things this size. Thanks for watching!
Sage Reynolds I can't see how that works. Surely when you hammer it, you're stretching it, that's how you manipulate it into shape. Like gum, elastic or whatever when it stretches, it gets thinner. Or are you saying if you had a piece of copper say 50mm square by 0.5mm thick and you hammered it and stretched it, to the point it was 60mm square, it would still be 0.5mm thick? Sorry I might be wrong but it seems that defies the laws of physicians!

This is a wonderful series! Thanks for uploading these projects :)
The piece is annealed every time you finish a round. Hammering hardens the metal and it needs to be relaxed or it will crack.

great asmr
hi sage. thanks for the videos. i have a qustion: do you neal agaun after the second raising or any other time along the process beside the first time?

thanks a lot. one more: how many rounds do you do for a cup?
Super! Thanks.
Hi Sage, where do you get your hammers? Both the raising and the planishing. I seem to find mostly small jewelry hammers.
Thanks

I can raise a small cup in 5 rounds, most people take about 7, beginners can expect to do 9 rounds before they have the cup they want.
This must be getting a bit thin by now. What thickness was the copper when you started?
