Sculpture and Art

Running Crank Shaft with Connecting Blocks and Temporary Rods I have the mechanism working on the latest Rolling Ball Sculpture and I’m now working on the track. The video shows the lifting mechanism working well and a short bit of track at the top. I intend to do…

Still-Working-On-It RBS Ball Lifter

Running Crank Shaft with Connecting Rods and Both Bottom Lifts I have a few still images for closer examination. Note that he connecting rod to the middle lifter is bent; this bent allows the link to move to a position where a straight rod would bind, hitting the…

One Connecting Rod In Place The length isn’t right or the location of the hole in the lower link, the one at the bottom of the long vertical rod, isn’t right. The ball lifter moves too far down. I’ll have to take some measurements form the original plan…

Running Crank Shaft with Connecting Blocks and Temporary Rods The video shows the two connecting rod end blocks in place. They each have a screw with a piece of 3/16 rod attached for the sole purpose of testing the blocks. The blocks will have rods attached to the…

I just did a small side project because I need to cut some thick material for my RBS Lifter mechanism. My dad built me a shaft extender and I installed an old Bodine gearhead motor on my band saw. It’s really slow now. This is probably more than…

Motor, Chain, and Crank Shaft The video shows the motor turning the chain and the crank shaft. Some of the parts in the video are not quite finished but I really wanted to see if it all worked together ok. Actually, when I put it together like this,…

The Jig and Crank Parts I built the parts to the crank shaft and then drilled some holes in that long aluminum plate to hold the parts in place. I thought that the holes in the crank parts would hold the rest of the parts in place, but…

Back Plate with Motor Mount The back plate attaches to the back of the frame and holds the motor and one of the bearing tubes for the crank shaft. I call it a “bearing tube” because it’s a short tube brazed into the metal plate to hold a…

It occurred to me that a link that is used only to change the direction of link movement, like the one pictured below, is sort of an idler link. it’s like an idler pulley because it doesn’t do anything on it’s own. An idler pulley keeps tension in…
