Fabrication Day

Finally, a solid day of fabrication in and lots of progress made.  The cleanup on the casting isn’t quite where I want it to be yet, but a few tweaks and it will be ready for paint and some rust.  I haven’t cast a large-scale concrete piece in a while, so I’m excited to get that ball rolling soon.  The first few are process pics of the drilling out of the cast iron hinge, and the fabrication of the steel mounting bracket.  The last few images are of the fabricated components sitting down in the concrete form work, they will need to be centered and supported once the concrete is poured.

    Quick questions: How do you apply rust? How do you move that piece once the concrete is poured?

      moving the concrete can be a pain in the ass, so I’ve had to devise ways to make things come apart, and be hollow. The pylon piece that this is going to go into is only about 3′ high and 12″ diameter, but it’s hollow, with 1.5″ cast concrete walls. I’m guessing it will be in the 150-200lb range. not fun to move on your own. The rust is easy, that’s just water on the raw cast iron. I’m applying a green epoxy paint first, but a fairly thin/un-even coat to allow some rust to come through. I did the same on the “unhinged” piece, then just dropped it in a bucket of water for a week and it was nice and rusty.
