stephen jendro - rolling ball sculptures - kinetic metal art

rolling ball sculptures are creations of philosophy, imagination, and varied skills and processes.

philosophy, inspiration, and imagination
a very dear friend of mine, while watching a few balls come off the rails, and a couple other balls get stuck, remarked that the sculptures were very lifelike in that way. i create these simply because they are enjoyable for almost everyone to watch, and because i am compelled to build them.

sketch
i draw sketches - e-mailed to customers so that we can understand a design direction, and used by me to help guide building. the sketching of the concept is important - without it, the sculpture can end up being quite different from what i was envisioning.

varied skills and process
a list of what goes into building these puppies: art design, kinetic art, architecture, metallurgy, blacksmithing, industrial safety, welding, electrical design, physics, mechanical engineering, storytelling, Web design, marketing, photography,  technical writing, amusement park rides, woodworking, Zen and Buddhism.

frame
using the sketch, i cut and weld the frame from 3/8" stainless steel rod, along with smaller diameter rod for frame support pieces and stainless steel balls for the ends. i spend a lot of time and energy on the frame as i feel it is an integral part of the overall design.

solid surface panels
i prefer to use a solid surface panel (corian-like) material in my work to help define the space - the panels are available in a great many colors.

painted elements
i use powdercoat painted elements to further define the space and to highlight key kinetic elements. I have even powdercoat painted entire sculptures for a terrific look.

lift
i build the screw lift using 1/8 rod along with a low power, safe, dc motor. the motor driven, uniformly wound, rail guides the balls up to the top of the sculpture for an engaging and continuous experience.

rails
i hand bend all the rails and weld them all together. i pretty much start at the top and work my way down. having the frame match the drawing is very helpful at this point of construction as the rails begin to have a very direct say in where they want to go - and i have learnt to listen to them.

kinetic elements
types of kinetic elements used in my work: spiral lift -spinner - drop arm - dips - jumps - funnels - spirals - waterfall sections - switches - and more. what would you like to have happen in your sculpture? 

balls
both steel balls and glass balls can be used - i prefer glass balls as the wide color possibilities of the glass balls compliment my design. plastic balls are available where quiet operation is essential.

testing, testing
testing is a continual process - to help ensure the customer's investment in this unique art. i am always having great fun hopping around my studio chasing and catching glass balls - and i never tire of it.

overall finish
the sculpture's finish is of great importance, i use an industrial steel finishing process that makes for a uniform satin steel finish, removing all weld marks.

shipping
your sculpture will be shipped to you in a very strong hand built wood box, and come with instructions for mounting and use.
