bigb Posted September 10, 2017 Share Posted September 10, 2017 I have a bunch of these ground rod pieces, hate to toss them, any ideas what to make with them? They are 5/8" steel with a very thin copper plating. Varying lengths from 3 to 5 feet. Quote Link to comment Share on other sites More sharing options...
Don Shears Posted September 10, 2017 Share Posted September 10, 2017 My 2 cents - Weather vane Mast/Support pole (?) The copper plating should tarnish to a nice green. Or use some as a trade item/Iron in the Hat offering at the local BS meeting(s). And just like here, ask those folks for suggestions.

Jasent Posted September 10, 2017 Share Posted September 10, 2017 I made tongs from them but the one I used had almost no copper left on it. It just melted off in the forge Quote Link to comment Share on other sites More sharing options...

Irondragon Forge ClayWorks Posted September 10, 2017 Share Posted September 10, 2017 I tried forging one I had into a dinner triangle. Mystery steel that didn't forge well and one bend cracked and fell apart at orange heat. Quote Link to comment Share on other sites More sharing options...
Frosty Posted September 10, 2017 Share Posted September 10, 2017 Ground rods tend to be about equal quality as rebar. I've never had copper effect my ability to weld with my forge. Then again the same guys were saying you can't weld with a NA gas forge so maybe I'm imagining things. I think in the day before reasonably clean, uniform steel was available welds might maybe could have been poisoned by contaminants in the fire. I don't recall the book I read about copper and zinc poisoning a forge but books of the same era, maybe the same books, talked about forge brazing with copper wire or penny shavings. Maybe . . . non-toxic copper? Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
bigb Posted September 11, 2017 Author Share Posted September 11, 2017 I think I will just cut them up in little pieces on the band saw and tack them to a base plate in a circular pattern for a basket/pot. I'll make them uneven for a more interesting look. Keeping them out of the forge will retain the copper finish too, except for the cut ends .Maybe save one for a weather vane pole as Don suggested. It's been a long, hot summer here and I didn't do any metal working except some sheet metal, finally cooling a bit and I am getting ready to spend some time in the shop. It's still near 100 but I am getting ready....... Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted September 11, 2017 Share Posted September 11, 2017 it cooled down to 90 deg F, 32.2 deg C, here; but still more humidity than back up at my main place...I felt like I was doing a "Lot's Wife" impression when I finished smithing yesterday.

jeremy k Posted September 12, 2017 Share Posted September 12, 2017 I had a hammer-in at my place and during the demo (a member was forge welding a bunch of wire cutters / electrical pliers) for a retired lineman / electrician and during the forging a guy walked up and thru a penny in the fire and said " see if you can weld them now" - I about dropped the guy, but the member doing the demo was irritated but successfully welded the parts together for the billet to make a knife for the retired man.

Steve Sells Posted September 12, 2017 Share Posted September 12, 2017 well I forge bronze in the same forge as I weld never had an issue so I cant see how it could be that copper prevents forge welding. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted September 12, 2017 Share Posted September 12, 2017 SOFA had a demo at a meeting one time where the smith welded using a dirty fire that he had added fly ash, sulfur and copper to and got a weld that passed testing. Biggest problem with copper in the forge as I recall is that it can get intragranular in steel and weaken it greatly. Ah yes "Intergranular Attack of Steel by Molten Copper": files.aws.org/wj/supplement/WJ_1978_01_s9.pdf Sure feels good when I find out I remember some things right after all...

bigb Posted November 20, 2017 Author Share Posted November 20, 2017 Well I finally got around to doing something with the ground rods. It didn't involve forging though. After a lot of thought I thought I should just turn them in to the state. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted November 20, 2017 Share Posted November 20, 2017 Pity they would have made great accent pieces for parts of designs that don't require any forging. Just there they look like a set of pan pipes... Quote Link to comment Share on other sites More sharing options...
bigb Posted November 20, 2017 Author Share Posted November 20, 2017 oh there's more where those came from. I almost made a New Mexico because the shape would have been easier, but being copper it only made sense that it should be Arizona Quote Link to comment Share on other sites More sharing options...

bigb Posted November 20, 2017 Author Share Posted November 20, 2017 Where we live the soil is very rocky. On a service upgrade we sometimes have to abandon a rod when it will not go in all the way. We cut it off and drive a new one. Sometimes it takes 3 or 4 tries to get one in, or a backhoe must be called in. Once they stop going down it is nearly impossible to pull them back out as they are wedged into rock. Using one that has been cut off is a no no and can be verified by the missing numbers that are stamped into the side of the rod near the top. Thankfully all new construction in the last 20 years or so has been required to have a UFER so no grounding rods needed. Quote Link to comment Share on other sites More sharing options...
