Rods used to resize worn holes???

I have a set of carbon rods(I think they are carbon) you put them in a worn hole then you can weld around the rod and the weld will not stick to the rod. You end up with a round hole the size of the OD of the rod. I need some bigger ones of these. I can't remember what they are called. I am not having much luck finding them. Do any of you know what they are called and where I can buy some?????
 
JD Seller, can't help you with the rods, but can tell you how I fixed the tongue holes on my ole JD offset disk. I cut the hole out a little bit with oxy-act torch. Cut a piece of heavy wall pipe one quarter inch longer than the thickness of tongue. Let 1/8 inch stick out both sides equally. Filled in around the pipe with stick welder. Ground it all smooth. Have a perfect hole through the tongue, exactly the size I wanted for pull pin to fit through. Tom
 

I repaired the stabiliser bracket on my Ferguson 35 using copper pipe . Used in exactly the same way as the carbon rods , the weld won't stick to the copper and you are left with a perfectly formed resized hole . The only disadvantage is that you only have a few copper pipe sizes to choose from but then redrilling the new weld up from a smaller size afterwards is always possible .
 
Tom Thanks for the reply. I have done that as well. This hole is the bottom hole on a pivot on a smaller articulated loader. It is in a real tight place. I can reach through the top hole and weld the bottom one to size. Then I will cut the top hole out and weld in a hardened bushing in it. I can not get to the bottom hole well enough to weld a bushing in it.
 
You could use copper rod. I put copper behind some thin metal to keep the weld flush. I never tried it to keep a hole open.
 
JD;
If you find them post the source please. I've never seen large carbon rods. If I'm not mistaken even lantern batteries just used a stack of smaller rods.

Copper rods, tubing or fittings will work but the copper draws a lot of heat so you have to turn it up so you don't end up with a cold weld.
 
Contact David Shaeffield in Fort Gibson Ok. at 888-478-4558 He makes and sells kits of carbon rods for welding holes from 1/8 inch to 2 1/2 inch. Good luck
 
JD Seller;

One source of carbon rods is a welding supply shop where they are sold as air arc gouging rods or carbon arc gouging rods. I suspect that you're looking for larger diameter rods, though. In that case wrenchere85's answer is probably the information you need.

The local blacksmith from way back when I was a kid had a large supply of carbon rods he had salvaged out of dry cell telephone batteries. From the era of hand crank telephones.

Maybe I'm a bit slow but I usually have trouble welding in a narrow space, how do you get penetration on the drawbar when the rod is stuck down a little gap? Or is the carbon plug raised bit by bit? Even without a plug in the way I find it hard to build up the side of an egged out hole, I must be missing something in how to do this.
