This has nothing to do with castings, but perhaps some ideas for Dave's place. My wife said "Don't buy this place, its a dump", but the framing was solid, no termites, and a pretty good and relatively modern HVAC system. It did have a bit of the "Bates Motel" look to it when we bought it. The woman we bought it from was seriously into "RED" everything. We bought it for a good price, but spent 7 months renovating it. I think it turned out well. New kitchen, new floor tiles, paint inside and out, refinished wood floors. Uses water-based floor finish, and really like how that turned out, plus no fumes to deal with. I did the granite countertop work in the kitchen. That was not fun at all. Total rewire with new panelboard and service entrance. Moved the electric meter outside the fenced area. There was a huge overgrown oak tree right up against the back of the house, with gigantic limbs hanging ominously in every direction, and rot in the center. It had to go (trees are expensive to remove). New fence. There were at least two sets of old concrete fence post bases in the ground. I used the smallest gas powered auger to drill new holes in the ground, so that when I hit an old concrete base, it did not grab and spin me around like a rag doll. Used a Bosch triple laser device to get the floor tile straight, and that worked like a charm. Some of the tile flowed through three different rooms, and no problem with alignment with the laser. A few before/after photos. I need to cast some transition pieces where the tile meets the wood floor. I can't seem to find anything except thin cheap stuff. It did become obvious that I am no spring chicken anymore while we were doing the work. It takes a lot of Advil to do a project like this at my age.
