So i have to come up with a graphite electrode, I cant find a purpose made one, the only think i get on searches is glass pH electrodes, btw if anyone knows that purpose made graphite can be bought PM me where.
Use of the fuckin search engine provides several purposed options; pensils, batteries, charcoal. I think i can go out of my way and do a little "higher quality" ghetto work and buy a pure graphite rod (rod, teehee!) somwhere... How to i connect a lead off it thats some what perminate and efficient? - cant really soder a lead off it- suggestions?

I would suggest to use the clamps (right english word? or clips?) for auto batteries, you know, the kind that is used to connect the batteries of two cars if one is empty. Soldering won't work of course.

The American saying for this is "jumper cables".

Elementry,I know your just trying to help,but in his original post he states that he would like to find something a little less ghetto then a battery core.
Depending on what he needs an electrode for,but in my limited experience battery cores suck, as they tend to desintergrate after a couple of uses,and they are adequate at best when trying to remove stuff from them.
Welding rods are specifically designed to withstand heat and pressure and last many times longer then the carbon composite found in certain batteries.They also come with clamps.They also cost fuck all.Check out the tungsten rods.

Fair enough, I get your point, but ghetto is ghetto and you use what you can.
Though from past posts on the hive graphite welding rods seem to be made of a denser graphite so yes they would be better suited to electrolysis.
But as for using tungsten rods, well aren't they gonna impart tungsten ions into the electrolyte ? Surely the whole point in using graphite and platinium electrodes is because they don't react (well hardly) with the electrolyte.
Best of luck, what ever source of graphite is used

High density graphite is used in carbon brushes for electric motors, You can buy these at electrical repair shops for use in vacuum cleaner motors and other appliances that use brush motors in. Most of them come with a copper braid wire attached to them for electrical connection.
If the variety you find doesn't have any wires or caps on, dont fear :
Plate the tips of the graphite rods with copper !
Firstly scribe some cylindrical groves round the top end of the rod, then using copper sulphate solution, electro-plate the end of the rod(s) with copper. The copper plate can now be soldered to a cable and covered with insulating material if required.

Elementary: Thanks, i saw that post. Im not using batteries. Im considering just attaching some alligator clips right to the rod (rod, teehee) would this do???
I was also wondering if you can sodder a lead onto graphite. You can get low melt silver sodder from jewlery making catalog... hmm, maby drilling a hole in the top of the rod (teehee) puting wire down it and puting a screw in place... I duno suggestions welcome, but ill let ya'll know what comes to pass and works.
hugs, kisses and puppy dog tails for all

No you wont be able to solder to graphite, the only thing that might stick is the flux. Graphite is actually used as a lubricant.
That's why the sugestion of scribing groves in the graphite before electro-plating was made (to give it an irregular surface to hold on to).
Crock clips (alligator) should be find as long as the amperage is not to high.

Or just search google for graphite plate or stock. You can get a .25" 4"x12" or maybe 4"x8" for like ten bucks and .5"x6" rod for even less. much better and more professional. Actually this palce is cheap er than the one i looked ate earlier
http://www.graphiteblock.com/products.ht
look there 6"x6"x.25" seven bucks as much as a pack of batteries.

Do they still sell these ignition batteries anywhere? The electrode next to it came out of another ignition battery.

Why would you buy an expensive battery to take the time to take it apart when you can buy round graphite rods 6"-12" long .5"-2" dia for anywhere from 4.00-16.00?

I had two already that I used for powering the filaments of an old army radio that has subminiture triodes in it. Maybe you'd like to use one to start a model airplane you got with all that nitromethane, too.

No, probably not since the early seventies !
I remember batteries like that though, you normally had one for the tube heaters and another 70 volt battery for the HV drive (on so called portable radios).
That photo tripped me back polythenesam !
Anyway getting back to the subject (before I get my head bitten off) Have you ever noticed those massive blocks of graphite on trains that pick the elctricity up from the live rail (this will not be applicable to countries where their trains only run on overhead cables). I sure there's loads of them hanging about somewhere

I never noticed. I found steel plates and spikes near railroads before, but no electrodes.
