See log entry #1 here. I have made a bit more progress. I added cranks to the gear shafts so that when the gears turn, the cranks turn. The large squarish arms on the big gear were made oversize so I could get the hole in the right…
Continue readingSee log entry #2 here. I am making progress on the straight-line ball lifting mechanism. I’ve already cut and welded the frame rails and the motor mount is already been drilled and is ready for use. The frame rails are built from 1/8″ mild steel “bars” that I…
Continue readingI am almost done roughing out the frame for the new ball lift sculpture machine. I find that welding the various extensions to it causes a lot of warping and I need to heat and straighten it more than I would like. I also need to make a…
Continue readingNo, it’s not titled “Thrown Together,” that’s just a description of how I started it. As you can see in the video, the base is the working-platform for a previous sculpture (now sitting on a sheet of acrylic) and the motor mounts are just wood bits. First Full…
Continue readingThe next lifter needs a crank that oscillates for about 200 degrees of a circle. The only way to achieve that is to use a motor crank to drive a crank on the big gear that then drives the small gear and its crank. 100 degrees of movement…
Continue readingHere’s a picture of a lifter ideas I threw together. The cool part is that the ball is lifted almost straight up – this is a straight line approximation mechanism – without a typical elevator or chain lift. The line where the ball goes up is drawn for…
Continue readingRolling Ball Lifter #2 is done. Here’s some video and pictures of the finished product. A quick search of this blog will yield other posts about the construction process. This Rolling Ball Sculpture, Marble Run, or Kugelbahn, is mostly a mechanical ball lift. The track is minimal to…
Continue readingI made a makeshift part to hold the far end of the on/off switch pull rod. Here’s a few pictures: Once I make the decorative part to hold the end of the rod, I’ll cut some threads in the end of the rod and screw on a steel…
Continue readingI cleaned my garage and I’m back to working on a Rolling Ball Sculpture again. My garage was figuratively knee deep in stuff and almost literally knee deep in some places. I wanted to make some room to work on projects while also uncover the climbing wall. Yes,…
Continue readingI captured a few stills from this video because the work is just amazing. Credit for the stills goes to the people who produced the video; Seiko. The comment on the video says “The meticulous attention to detail and artistic beauty of the time.”
