From Scrap to Stock: Rolling Silver Sheet
Вставка
- Опубліковано 29 чер 2024
- In part 1 of this series on recycling metal ( • From Scrap to Stock: S... ), John Sartin demonstrated how to take silver scrap and turn it into an ingot. In this video, John walks you through the steps to turning that ingot into sheet you can use for your next design. Follow along as he files, polishes, removes casting scale, forges, anneals and more before thinning the sheet on a rolling mill. In part 3 ( • From Scrap to Stock: P... ), John takes an ingot and turns it into usable wire.

Hi. Have been as an hobbyist making silver rings and other for few years now and i decided to make my own sheet and wire, so i got for myself a rolling mill. I have watched many videos here on tube and i thought i knew almost everything what comes to casting silver. Oh boy, was i wrong. After watching you tutorial i learned so much more. And the video was so well made and your narrative clear. Thank you for sharing your craftsmanship.

@@RioGrande1944 Why would an ingot have oxides layers underneath the surface? Thankyou!
By far, the best video I’ve seen on preparing ingots & how to roll them. Thank you!
This morning I am planning to roll out an ingot into a sheet. Will be making tube shaped ends for a fox chain I finished yesterday. I have a used rolling mill that I got from a real jeweler who was upgrading. This set of videos told me exactly what I need to know before making myself crazy trying to figure it out on my own. I am very happy that I buy supplies from Rio Grande. It allows them to make these videos so my hobby projects leave me with pieces that I actually want to wear or give away.
Brilliant!!! I am going to be investing in my very first rolling mill and I cannot thank you enough for these very informative instructional guides!!
Thank you so much for sharing how to correct a wave in the sheet. I had no idea that was caused by starting and stopping. Very informative video! Thanks so much!
You are so welcome!
I have been working bond Street for more years than I can remember and I think this video and others help you to reassess how you do things. Thanks
Liked the forging suggestion, that would help and the waves from stopping make sense and something that has happened to me. Thank you
Invaluable information and great detail. Thanks so much for taking the time to make and share this movie.
You are welcome! We are glad you liked it!
Excellent training video
Thank you-this was so helpful!
Thank you for the knowledge
When I consolidate the grain structure/ Forge the ingot, I leave the little nubbin on the top of the Ingot as something to grab onto with pliers. And then I cut that off after the initial forging
This was so very helpful. I have never heard this before, thank you. Is this method the same when gold is the metal used?
Why would an ingot have oxides layers underneath the surface?
Thanks Brother 🙂👍💯
So much fun.
Thank you for watching!
Casting scale and rough surfaces themselves are inherent stress risers. I like to even chamfer my edges
Great video! Do you think it’s possible to use a similar rolling mill to straighten a 0.5 mm brass sheet that is already quite flat? Ps: I don't need to get a thinner sheet, I just want it to get as planar as I can with a tool that wouldn't break the bank.
Great video, thanks so much. What is the Fretz hammer code please? There are so many I find it very confusing!
You're right, there are so many Fretz hammers! This one is the SH-1 Jeweler's Sledge, and you can find it here at Rio Grande: ow.ly/R4eK50E6q5v
Thank you so much for this second video in the series. Has Part 3 been published yet?
Ok. I am learning a lot about what I'm doing wrong (probably) from this video. Thanks heaps.
quick question - if you do end up with silver oxides in your metal, how do you reverse that? (reducing flux perhaps - presuming a remelt)?
also, what does overannealing manifest as in terms of rolling behaviour? cracks and splintering?
Hello! Thank you for the question. Here is the reply from out tech team: Oxides are always going to be an issue with open torch heating and melting, that’s why closed system casting with a Nitrogen cover gas is such a big deal. You can mitigate some of the oxides with torch control by not pulling the flame off of the metal when melting,, and not using too much of an oxidizing flame, also flux will help to a small degree. Once they are in there I don’t know of a way to get them out, refineries do it but not sure how.
Well I had this idea to use old 925 jewelry to make sheet stock. So from your first video, the solder from jewelry can affect the end product?.😳
Yes too much solder would effect the ingot making it brittle and prone to cracking. It can also reduce the melting point of sterling and cause the metal to tarnish quicker than usual. It may also create an alloy that is easily reticulated. To avoid this you'd want to be diligent about sanding or cutting away the solder. Hope this helps!
Can you please give an advise on the best thickness of an ingot to go inside a rolling mill. Is 7 mm too much or ok to start with your process shown on this beautiful video? Thanks a lot
Each rolling mill will have a maximum sheet or wire thickness, some are 7mm for wire, but each is different. If you look in the “additional specifications” of the product page, they will have those sizes listed.
What’s the pre flux mixture with alcohol and boric acid?
Good question, the mixture of boric acid and alcohol (methyl or denatured) creates a barrier flux to prevent firescale. You can find out how to mix it here, ua-cam.com/video/Bfd8DukeCLI/v-deo.html. You can also check out the products at Rio Grande: Boric Acid - ow.ly/L7M850E6qnt, Methyl Alcohol - ow.ly/JWu650E6qty
Cant you just get rid of the oxides by melting it and boraxing it?.....then pickle?
Thank you for the videos. I have watched several videos and it looks like everyone turns the handle like its not difficult at all. I find it very difficult to turn the handle (4:1 ratio) on my pepe rolling mill when making sheet. I will run it through several times on one setting and adjust a tiny amount and it requires a lot of force to turn it. I have annealed several times through the process. Im not sure what im doing wrong It is only easier when i run wire through or small ingots for sheet. I am going to try working it with a hammer first and see how that does. Im have worked with had tools my whole life, HVAC work is very physical so its not because im a "pussy"
Thank you for the comment.
