Metal quantity calculation

Hello everyone,

Again I have doubts!

I am unsure of how much metal grain to order for making two wedding rings with a strip of yellow gold and white gold.
The goal is to create a 19.2k alloy by combining 18k and 24k gold.
I have calculated the amount of metal required for the final product, but I am unsure about the additional metal needed to cast an ingot, roll it into a sheet, and cut strips for the wedding rings.

  • How much extra metal should I order to account for this? Is there a way to calculate this or should I order a certain percentage more?
    The wedding bands should end up being approximately 6gr of yellow gold and 11gr of white gold.
    I’ll be casting a round ingot and I have a combined rolling mill to transform it after. Starting with a 4mm round wire and ending up with a 1.8mm thickness sheet with 1.3mm height for yellow gold and 2.7mm height for white gold. I also have a rectangle draw plate that might help for the initial form shapeshift I need from round to rectangle.

The price of gold greatly affects the order cost and quote for my customers.

Thank you in advance for all your contributions and for sharing your knowledge with me!

I have searched this forum with various keywords, but I have not found any relevant information. I apologize if I missed any similar topics.

Wish you all a great day!

Stamping curb link chain

Just finished adding a few extra links onto a customers curb link chain and they would like each link hallmarked to match the rest of the links. Does anyone have any advice on how to/what to use to brace the back of the link. Was planning on using a small dapping punch secured in a vice. just went to try it and discovered I need to grow an extra hand, one to hold the chain, one to hold the stamp and another to hit it with a hammer.
All advice welcome and appreciated,
cheers!
Matt

There are many useful, brilliant tips to be found in his project descriptions.

Apparently a number of pieces were stolen from a self-storage area.

Welcome to crafthaus, the network for craft artists, and those who support them! I am very glad you joined us !

Please feel free to look around, meet friends, and start adding your thoughts to the groups, blogs and discussion forums that are posted. Of course, if there is something else you'd much rather talk about, please add that to the site so that the rest of us can chime in. Crafthaus is a participatory sport ! The more you put into it, the more you will get out of it, for sure.

Please note that crafthaus is both a fully edited and a member-financed website, meaning that a small annual fee ($20/yr or $35/2yrs) is involved in being a member here. You will find all the necessary information on how to go about this in the FAQs section of the site. Your membership fee is due on or before July 15, 2010 and is payable through paypal (preferred,) US check or credit card.

ALL images sent to the website editor will be vetted to assure some measure of overall quality control. Unlike other image sharing websites, crafthaus is not a "free-for-all". Members present their work in front of an educated and critical audience (their peers,) so the images have to be GREAT. Our goal is to show our members' work in the best possible light, and from the many images received daily, we try to post as many as possible. Crafthaus heartily encourages comments from the membership, however with regard to photos posted or not, we have a strict "NO WHINING" policy in effect ! If your photos do not get posted they are just not as good as they need to be. Yes, it's really that simple. Just reshoot and resubmit ! No harm done.

Finally, if there are ever any questions or concerns, please don't hesitate to email me via crafthauseditor@live.com anytime. I will do my best to be of help. I really hope you will enjoy being with this network, and will find the exchanges interesting and fun.

Again: Welcome and enjoy !
