My kind of work!! I just

My kind of work!! I just love making things do stuff it does not want to. Great piece.

So how did you mount the concrete?? Are the beams just cut and bent at the joint??

i give it a few weeks..

thanks. what i like most about steel and concrete is that you can make them do things that seem impossible.

the concrete block on the top actually has a foam core. i suspended the foam with steel rods in the wood form. still, the block weighs about 80 pounds. the bottom block is solid, with the beam welded to a platform set into the concrete.

the beam actually is two beams welded. i suspect that bending a single beam would stress the steel to the yielding point, thus losing its strength. on the other hand, the weld is fairly thin, and the heat certainly changed the steel's properties for the worse..

i give it a few weeks..

Nice work, I agree with you

Nice work, I agree with you and Kevin. Steel has that wonderful ability to show off its' strength and provide some structurally unnerving looking pieces. Got to love this material.

How he do that?

Keith,
Really Cool, I love daring ideas!
This one really makes you wonder, will it or won't it hold? Of course it will!
Nice Job, I like it!

Balancing Act

Keith/Man-O-Mettle;
What's next; the tight-rope walk? I think you need to use some color to accentuate the piece against the general green background. Perhaps orange, red and purple? That would really make it "POP"!

questions

thanks all for the encouragement.

a question keyed to nic's comment: i want the beams to rust, but i am concerned about the welds weakening. any thoughts on how to allow the rust but protect the welds?

also, the concrete -- any suggestions about how to seal it?

as for color.. i had envisioned the piece in the middle of a vast green sward, not against trees. but it turned out this was the best place for display.. so..color would help, but i think it is too late...

For the concrete I have used

For the concrete I have used this https://ecom.granquartz.com/VIA9/viaListProducts.jsp?searchText=rock^epoxy&modifier=SEARCH&reqTitle=TITLE_VIASEARCHRESULT

It is a two part epoxy for stone. Have used it to seal fountain basins. Works like a charm!!

One option might be to use

One option might be to use weathering steel (corten) flux cored filler wire. I believe i got ESAB 8100. It's a sprayarc application and it goes on like hot butter, and i do mean hot. Great looking welds though. I'm sure you can get it for stick welding as well, but I've never tried it. Its going to mix with the base metal, so if you can use Corten for the base metal it'd be best, but for what your doing the wire might be enough. If you added a small(1" roughly) gusset in the joints of the girders, you'd take a lot of stress off of the welds, but that might interfere with the look your after.

I always like the natural rusting look of steel, it's got to be my favorite finish.
