We were living in the house I was born in, was 100 years old, and I believe was made of lumber that the sawmill on the homestead couldn't sell. No insulation, bad windows. old wiring, failing plumbing, no foundation, and a shake roof on its last legs. We had to do something, but the Great Recession had ruined the market for our logs, which was our main source of income.
We had savings, and decided to use it to build a 40 x 100 foot all-steel shop building and make one end of it into a two-story "apartment" to live in until things turned around and we could build on the site of the old house. Once we had moved in, our twins (a boy and a girl) loved not having to share a bedroom, and we actually had insulation! We made the interior sort of "industrial" by leaving the I-beams exposed, using rubber baseboard and applying a clear epoxy finish on the concrete slab floor.
One place my wife insisted on making nice was the kitchen, and she found a deep double sink and flexible-head faucet at Ikea that she liked. The problem was that it was designed for a countertop with integral backsplash, and had a brace that needed to attach fairly high on that backsplash. Since she insisted on having a window over the sink, there was no place to attach the brace.
After giving it some thought, I figured that if I could attach something to the window sill, I could make an adapter to connect to the brace. I prowled the scrap metal yard, and came up with a couple of large satinless steel bolts that could supply material for the adapter. I turned the larger bolt to a diameter large enough to allow me to make a pocket in one side for my threaded adapter to nestle into. I also drilled and tapped the bottom for a stud that had machine threads on one end and wood threads on the other. After contouring the upper end of the adapter and using an end mill to make the pocket, I made an adapter to lengthen the brace, which had a metric thread on the female end and a NC thread going into the pocket.
It all turned out pretty well. It has been in service for 12 years now. We still haven't built the new house, because this one is so comfortable, and laid out to be so livable. We just installed a 19 KW solar system that feeds the power grid and they credit us against the power we use when it isn't putting out as much as we use.
