Default Re: any machinist can work with silver?

Do you mean pure Silver or Sterling Silver which is an alloy of 92.5% pure silver and other metals such as copper which adds strength.

If you do mean pure silver, it is really soft and it will tarnish like a son of a gun.

ID= inner diameter
OD=outer diameter.
if so what is the minimum required length to work with?
i need it to hold 2 x 18650 battery.

or should i buy stock bar instead?
I'd chat up Ehgemus maybe send him a PM, he makes really nice hosts, you'll just have to give him a general construction design and make sure he'll be able to do it for you in sterling silver, you could either buy it yourself and have it shipped to him or ask him to buy it and you can pay him. He's got nice quality hosts and a good reputation, I recently ordered from him and shipping is already speedy, I can't wait to receive it I'm sure he'll be able to do something, and btw why sterling silver?

Diamond is actually the best thermally conductive material, why don't you give that a go? It would only take a few millions/billions of dollars and extremely industrial machinery to construct

I'm kidding Sounds like a cool idea! Maybe a bit expensive though :P I can't say for sure because I don't actually know, but I would think copper would conduct heat a lot better? Just think about wires, I've never commonly come across sterling silver wires haha

I think it's a uniquie idea, as having a sterling silver host would be badass (and shiny)

Well you sure did your homework. According to this chart, pure silver is the best.
I learned something new today
Copper is a really close second.
Thermal Conductivity of Metals

May i ask what shopping centre these Tungsten/silver/aluminium hosts/blocks of metal are in?
Sounds like a shopping centre i'd enjoy.

Default Re: any machinist can work with sterling silver?

you could do pure silver for the heatsink and have the rest of the host made of something else. if it was designed to conceal the heatsink then tarnishing wouldnt be a problem. copper tarnishes too though. with how cheap silver is getting, been considering this myself. it's not too much beter than copper though

Stridast made a few hosts from silver, which he sold. Here are a couple of examples:

Solid Silver - 520nm Build [PIC HEAVY]


AND just in case the debate should start again! here's some interesting info!

I want copper copper copper! (well... maybe not)
