Rolling ball sculpture: Flying Hulls

I created this commission as a Christmas present from a wife to her husband. They both share a love of sailing, and the piece is to be displayed in their boathouse where they often entertain. I used a photo of their own catamaran to build a frame that reflected its major details. Even though it is not as complex as my larger pieces, I still was able to bring plenty of life to it, especially with the ball jump!

New rolling ball sculpture: Dropping In

I've kept at it. There are a few sculptures between my previous post and this one, but I figured I'd at least post where I'm at currently.

This one was a challenge - no curves! None! I used absolutely straight and flat sections of track positioned at angles to each other and sloped just slightly to create movement in the desired directions. It took quite a bit of work to get it right, but it turned out very well.

New kinetic sculpture with video!

I've been hard at work making some smaller pieces, and I finally got a chance to get some video done. This one, like the larger works, is made from 1/8" stainless steel and uses a 1" marble. It's a fun little piece that is good for an office desktop or a side table. Hope you like it, and I do have more in the pipeline that I'll have video for soon!

New rolling ball sculpture with video! Title: Meer-col

So, been busy! Got a last-minute notification on a call for subs for the freakin' mayor's office! I've never tried for anything like that, but any exposure for me is good stuff. Plus, I only had a few days to produce something, and I knew that I had to test myself and see what I could (or could not?) do in only a few days. The short story is that I did manage to finish it on time, and it got accepted!

It is TIG welded and uses 1" marbles and is all of stainless steel. This piece is unique, because for its size the ONLY moving parts on it are the marbles. The track switch doesn't even have any moving parts! It's the first time I've tried one of those, and it turned out nicely.

Enjoy!

New Rube Goldberg machine completed! Title: #30 Molar

This one has more loops than anything I've previously created! It's super cool! (I dig it, anyway.) It's made entirely of stainless steel and has actual dental instruments welded into it! The frame is a giant tooth, containing nice wavy, gently sloping bends and quick curves, two tracks, a track splitter switch and two big spirals. I hope you like it.



As an aside, it's too bad we don't have more sculptors posting here, or at least some links to fun videos that fans have found.

"Opportunity" Rube Goldberg machine completed

I took on a commission for this piece about a year and a half ago. It was a major undertaking, one not even I fully realized at the outset (isn't that always the way?). It has been worth every minute of it, however. I am very proud to present this fantastically entertaining rolling ball sculpture that is all of welded steel, over four feet tall and has a motorized chain lift that carries the 1-inch marbles to the top so you can just sit back and enjoy the fun! I hope you all like it. Any comments or questions are appreciated. More of my work can be found at www.tomharold.com.

New kinetic sculpture vid

I've completed another wacky marble machine, also called rolling ball sculptures or, of course, Rube Goldberg devices. This one is made out of plain steel and uses a several pieces of steel scrap fished out of the scrap heap at work. It also has a fun sound element to it, altogether a cool piece and fun, especially given its size. The steel has been specially coated with a clear coat so that it will never rust, yet the ring still comes through just great! I plan on doing a series of these and offering them at a price around $175.

Stainless steel rolling ball sculpture completed

Here is a photo of a rolling ball sculpture that I recently completed. It uses one-inch marbles. Most of it is 1/8" rod, but there is some perforated stainless on there as you can see, and the pyramid that forms the frame is something like 3/16" or 3/8". There is a hand-operated starting gate, one spiral, a loop-the-loop, and there are actually two tracks, the initial track being split into two using a tipper-style splitter. This is obviously a big change from the pieces I was doing formerly that were of copper wire. It has taken a lot of practice to get my welding skills together well enough to make a piece of this quality.

I will have a good quality video of this one to post in the near future, which should be much more fun for everyone than just the static pic, but you can get an idea of what it looks like at least for now.

One more copper piece with video

I did this piece for my nephews and put together a video of it as well. The video is not the highest quality, but it will give you an idea of how it operates. As with my other pieces, this one is copper and brass, soldered. It uses standard-sized marbles.
