Marble Collectors
Marble collectors can be very handy when making your rolling ball sculpture. They can store marbles and release them at the same time. This can give you several marbles going together. When you need marbles to go at the same time then this is the element for you. Also, if you build the collector so the marbles tip out sideways, all of the marbles will get getting started at the exact same time.

If you need to slow down the marble, or collect several marbles together, then this would be the element you want to use.

This picture of #59 shows both of the marble collectors.
The collector in front has the black marbles with a colored
stripe. The other collector is in back, is just tipping it's
marbles onto the track, and has the clear marbles with
orange, white and blue in them. The collector in back tips
when it has 7 marbles, and the one in front with the
black marbles tips when the 8th one rolls on. All stainless
steel track. The frame is made from 3/4" stainless steel
square tubing. All of it is TIG welded. The colorful
glass marbles are 1 inch. The helical lift can be seen in
the back, raising the marbles automatically to the top.




This arm is on #56, the wall hanging art sculpture.
In this shot there are no marbles in the collector.
The orange marble hanging out under the arm is
the collector's counter weight. This weight returns the
arm when the marbles are released. It has to be
very carefully placed, it's weight is very important.




This arm is also on #56 the wall hanging sculpture.
This arms tips when it has 8 marbles, so it's got
two marbles to go before it releases them all.
I use a bronze bearing that is self lubricating.
It fits a 1/4" steel shaft and is friction fit into
the middle of the plastic. I drill holes in the plastic
so I can insert wire through them. This keeps the
bearing in place, and the arm firmly attached to
the pivot point. The bearing eliminates the need
to oil, and will guarantee long life of your sculpture.
