[fafrd]

don't qoute me on this but if he bought 15 sq ft roll it's probally size 16 mesh i personaly was thinking maybe 8 mesh but i'm a newbie so only he knows but if you look at all the pages u will see that min order at 15 ft would be 16 mesh i'm new and presently waiting to get a cell to process my first batch of material and i'm hopeing this will make it a better cell to use with less maintenance

 

[lazersteve]

I got the 16 Mesh, I didn't see the 8 mesh.

I just placed a web order which required no contact with customer services.

 

[M-G-P]

fafrd,

It's a small price to pay considering the interest expressed here by the forum members. I'll do whatever I can to help us all.

you know what I did for my cell?.. I had "gold plated" bangle bracelets. so I hung them in the cell by stringing a light gauge (0.012) high "e" string (Stainless) from a guitar across the cell and then taped it to the sides with a conductive tape, the string was not submerged and all I had to do was occassionally rotate the bracelets on the string so that the "gold" side would be in the solution.. it worked fabulous! For pins or other things, I plan on putting alligator clips across it like clothespins to suspend those types of items in solution.. On the other side of the cell I put in a plastic dowel that I coiled another guitar string ( 0.059 heavy-gauge) like you would see in one of those old crystal radios.. (pic is just for reference)..

yea it looks good but what are u going to do with 75$ of copper mesh screen it sounds like we as a group need to pitch in and buy about 10 square feet of it so everyone can get some with out going broke just an idea then u need to decide what size would needed

:idea: could you not find copper mesh at your local art supply store?>> :idea:

Here's a good source for smaller (and much cheaper) quantities.

http://www.dickblick.com/zz334/08/ (a good artist supply online catalogue.. I get lots of my art stuff from here..)

they use it for making a form to put sculpture clay onto.. much smaller quantity.. also, I'm confused.. I thought copper was somthing to avoid sumberging "charged" into your cell?.. am I confused?. (sorry, been trying to process so much info over the last few weeks it gets bit confusing..

 

[fafrd]

know what i live in a pretty good size town with 1 major college and 2 small college's and we used to have a great store but it closed up about 2 years ago so no i don't have a good art supply or craft store in my town sorry about that maybe i need to relocate for you lol no won't do that i like being close to the wild

Mayhem,

According to a very trusted source (our beloved Harold :wink: ) he has seen copper is used in large scale cells as a basket for the anode. I did a little checking on the reaction between copper and sulfuric acid and found sulfuric should not readily attack copper unless the acid is the concentrated stuff and it gets hot. Since we are working with concentrated sulfuric acid and we shouldn't let our cell get very hot, we should be okay.

Awesome, thanks Steve.. I was wondering about that, because regarding the cells I've read a few posts where people said they use specifically SS alligator clips and things along that line, also, I just noticed that the clips on my battery charger (which look like copper, unsure of their composition though) were a bit corroded.. so naturally I figured copper was a no-no.. I'm glad we got guys like you and Harold around!

Also, I looked at those prices again.. hmmm... that big roll of the copper mesh.. I got a good thought.. a reallll good one this time (I think)..

Whatever goes unused could be sold off as "wireform mesh" on Ebay or whatever.. I'm sure there's plenty of artists out there that would snap it up. Especially considering you could way under sell the artist supply dealers and still pull a significant profit.. you'd certainly make your $$ back and then some..

I had the same thoughts at fist, but a little research backed up Harolds observations! The idea hasn't passed the test of fire yet though!!! We'll give it a whirl and let the forum know the results. As for the battery leads they are most likely alloys of several metals or some cheap plated material. I would not jump in and start using just any old clips for the anode leads just yet, the clips may experience enough heating to cause the acid to react. Try not to jump the gun and we'll all find out soon enough. :wink:

[AuMINIMayhem]

not jumping any guns.. toldja how I did it.. SS guitar strings.. they worked pretty well for what I was doing. I'm stickin' to those for now (plus I just happened to have a surplus of old guitar strings.. )

My wife uses a plastic coated stainless steel bead string wire, its cheap at Micheals or Hobbylobby. Fishing leader material at sporting goods places is also plastic coated.

Thanks for the ideas!

I am a noob and am still in the collecting phase, but I recently found a copper screen in an old industrial digital scale. It was used for noise shielding behind the digital display.

 

[aflacglobal]

If it's copper not plated or alloyed, and the holes are not so big as to allow your source material to fall thru it should work. Coming from that application i would probaly say it's realitivy pure in form. Worst you could do is have it dissolve in the acid. Might make you mad, but you would not lose your gold. Just back to the drawing board. Welcome to the forum. What kind of scrap are you going for ?
