Moving along with Burning man
Homer is really closing in nicely on the burning man time machine art car, he has the clock like gearing nearly finished for the carousel and the 20′ tall wheels that can be broken down for shipping to the event are outrageous. Ruby, Roman and I stopped by after a swim in the river to see the progress and were blown away by the size and strength of the wheels. David at Mainly Metals has a water jet cutter and is making all the gears so they can get just the right speed of the carousel, one turn to every 7 turns that the 20′ wheels turn.
I have volunteered to come up with the propulsion and was toying with having a diesel engine run a generator that would run electric motors but this seems a bit much for me. We settled on hydraulics to get her moving slowly in the desert and pawed through a number of catalogs to come up with the components necessary to get us rolling.
After looking at all of the components individually and seeing the huge variation of gallons per minute rates, pressure capebility and overall compatibility of hydraulic pumps to valve bodies to motors I had a great idea, cannibalize a skid steer loader! Someone else engineered the relationship of engine to pump to valve size to motors. Even the hose size and fluid reservoir are thought out for the flow and cooling capacity that we need.
Jeff used to work at our shop but now works closer to his home at a farm equipment sales and service place. I called him to find out where I could buy a cheap skid steer. He had me call Jon in Bridport and for under $3000 we had a operable machine that I began to disassemble right away. The 3 cylinder engine came out easily, in fact I slid it out of the machine and right onto the hydraulic lift table by myself. Now I have to find a way to remove the pump and hoses without having to undo all of the lines so the system stays clean and I can identify the scavenge side and the pressure side.
I am excited to work tomorrow to strip the motors for the wheel movement to see what we can use for the art car. With the chains and jack shafts that are in the drive housing maybe we need to do very little to hook the motors up to the wheels.
