The Ibis is now ready for the watergate. I thought I had a solution in the works with a professional watergate manufacturer wanting to make the gate aspect, but it looks like it will be up to me. That idea cost me a month waiting for a bid, but luckily this project isn’t due ’til April.
The Ibis cast clean and Nora drove down to Alpine with me to fetch all the bits from the foundry. I welded the windows in place ’til parts needed chasing prior to more welding; then I went and worked on the Mustang for the rest of the afternoon, because chasing is for the birds. The ‘ol ponycar has been getting a spa-treatment radiator flush for the past 3 days, and today was the last day of the process. I took her to a classic car show in Liberty Park last weekend, and being around car-guys got me past my procrastination.
I’ll drop in context later, for now go to Wetlands for an explanation.
Installation day started off raining and chilly, just how the fish like it. With two handy fellows helping (Jed, who helped install the last group, and Mike) things got started at 8am and finished by 3pm with time off for lunch at one of the restaurants on the plaza. A solid day of digging and lifting heavy things, but all are in the ground and everyone is happy.
Chemlab for fishies. The fish enter the sandblast tent and are stripped of all contaminants and oxidation. With the surface sand-scoured, all imperfections show up and I put in some last fidgets with welding and chasing- then back in the tent for a follow up visit from Dr.Sanders. The surface glows a muted gold, but is as vulnerable to the air as a ginger to the high desert sun. Like a base-tan with sunscreen, they need a chemical etching that bites into the bronze then goes inert allowing a skin of protection. The fish go black with this initial etching layer, but it allows other chemicals to safely react to the surface and bring out other colors. The fish will go blue-green (Cupric Nitrate and Zinc Nitrate) with hints of dun yellow and yellow-green (a few drops of Ferric in the solution), while the hoops will turn a rich brown with white in all the recesses.
Patina builds up with chemicals and heat, layer after layer. Control of the process is partly knowing when you haven’t gotten there yet with knowing when to stop, all the while blending out areas that come on too fast and bringing up areas that seem to never get there. There is quite a bit of alchemy to it, as it is a mad science.
I cleared the only chem shop in the valley of their Cupric Nitrate, a trace of 100g- or about not enough for one fish. They ordered more, it should have been in last Thurs/Fri, it wasn’t. I’ve used my reserve stash for the first 4, and have just the 100g left for this last pair which will never make it. The fish will have to set overnight and see if the order arrives tomorrow- not a hardship on the human to wait as temps peaked out at 98 degrees.
Ditto yesterday, in half the time; final fish poling.
200# of top-heavy trout need a way to travel safely. The wheeled frame is my DIY studio worktable sans top and low shelf, it pulls double duty as my sandblast and patina platform for big sculpture. I thought of this welded footing back in 2014 for the last group, but didn’t make it because I was too far down the production rabbit hole. Poling out the last pair didn’t even take the morning, so I scrounged through my steel scrap, planned the unit out and cut and ground the metal, and switched out the welders. E made me a quick lunch, and I was back out in the shop and it was welded out in no time. Two runs of channel iron make the platform, connected to a drop bar of rectangular “square” tubing. The platform floats just off the ground. I’ll build out my plastic tent for sandblast, and this can roll in and out. Key to the low footing is allowing transport out onto the parking pad for patina with good clearance for the garage door.
With the footing welded in, clamps and steel tubing hold the sculpture in place. 60# of weights on the far side of the sledge keeps all the wheels on the ground.
