You don't have to plug it in or fiddle with lots of mechanized parts that will eventually break. Pachinko gumball machine by ThreeBirdsCrafts on Etsy. Keeping up with Rockbuster and Bob Wemm is near impossible at the rate they both put projects out. Share it with us! This is a view of wood projects gumball machine 01 mechanism operating in its various steps and conditions. Pay attention to the photographs. It was great for a child who did not mind shaking the whole machine to make certain a gumball found its way into the hopper so it could be dispensed.

Of course, I was unable to take pictures of the project while I was building it no cameras are This unique and ingenious item was discovered at an estate sale.

The man that made it was very talented with his hands and created many useful pieces. This is such a great primitive vending machine. All you have to do is unscrew the ball jar, add your favorite nuts, candies, or gumballs, and turn the wooden knob. You don't have to plug it in or fiddle with lots of mechanized parts that will eventually break. Not to mention what an unusual and fun gift this would make! Get a bag of jelly….

Mason-Jar gumball machines come in many shapes and sizes. It is my own design. The two main parts are designated as "A" and "B.

The gumball loaded in hole "C" from an inverted glass jar above is pushed until it aligns with another hole below in the frame of the gumball machine not shown , and the gumball rolls down a channel not shown to fall into a cup on the exterior of the machine not shown. When the operator begins to pull the slide "A" back to its original position, the pressure on the edges of the coin is released and it falls through a slot below into a coin box slot and coin box not shown.

Part "F" is a piece of bent wire. It slides in the recessed channels and round holes indicated by the two "E"s. This also pulls "B" back to its original position so a new gumball can fall into hole "C" from the jar above. Although shown too small in the graphic, the round holes that are part of the inletting for "E" on each piece are a large enough diameter that if someone pushes "A" without a coin in the machine, "A" moves harmlessly inward, but "B" does not move forward and no gumball is dispensed.

Make the round holes in "E" larger in actuality. There is enough tension on "B" supplied by a light spring from below that it does not slide when the machine is tipped. The hole marked "C" should be just slightly larger in diameter than the largest gumball in any package of the type you buy and use. The photo shows the actual machine I made.

I was able to get it from my daughter and take actual dimensions. I am working on these photos from an iPad and I am forced to use text notes, which make precision difficult. Check for pictures in other steps and dimensional information to get a complete set of measurements.

This is a view of the mechanism Wood Projects Gumball Machine Image operating in its various steps and conditions. The first graphic shows a coin in place thin black rectangle The sliders "A" and "B" will travel from left to right. Notice the position of the wire red in the inletted holes gray.

It is just a little loose in the holes, but not much. The blue dotted line represents the change in thickness cut into the "B" slider. The green circle is a gumball loaded in the slider hole. The blue semi-circle is the hole to the channel where the gumball will be dispensed.

Notice also the position of the black limiting pin for the "A" slider. The travel of the "A" slider is just a tiny bit more than the diameter of the coin. In the second graphic the direction of travel has been reversed. The hole for the gumball shows a blue color to indicate the gumball has fallen down the channel. The coin is no longer visible and has fallen into the coin box. The limiting pin is now in the position to keep the "A" slider from moving any farther into the machine.

The wire red is firmly pulling the "B" slider backward in tandem with the "A" slider. The third graphic shows what happens if someone tries to get a gumball without inserting a coin. The "A" slider has moved inward as far as it can go. The Limit Pin is against the shoulder of the "A" slider. The wire red is loose and does not push on the "B" slider. The green gumball remains unmoved. Choose a glass jar about one quart in size. It should have a good sturdy metal lid. A one-piece metal lid would be preferred, but a two-piece lid from a standard home canning jar could work.

Make a hole in the center of the lid large enough to pass a gumball. Chisel by hand or turn the wooden disc on a lathe so one surface forms a cone like a funnel to help feed the gumballs into the gumball machine. Make a hole in the center of the wooden disc to match the hole in the metal lid.

Set the jar and the disc aside for now. The photo is from Bing Images. Begin by cutting a piece of Masonite the size of the machine's base. The hole is for the gumballs to fall down into a channel so they can roll to a cup on the side of the machine. The slot is for the coin to fall down into a coin box. Notice that both are closer to the back edge of the machine than the front.

It is impossible to give exact dimenions because those will depend on the gumballs and the coin you use. The red arrow indicates the width of sliders "A" and "B" from step 1.

Add two pieces of hardwood to the Masonite piece and glue them in place. Their thickness should be equal to the thickest part of "B" in step 1, which is the diameter of the gumballs. If you remember the description of how the mechanism works from step 1, "A" was only the thickness of the coin used. If the coin is smaller in diameter than the gumball, a spacer needs to be added.

The red arrow indicates the diameter of the coin. When the slider mechanism is fully pulled back ready for another coin, the step on part "B" will rest against the part of the spacer nearest the hole for the gumball.

A flat spring or part of a common safety pin could be added so it presses lightly against the "B" slider to guarantee that it does not move due to gravity, if the machine is tipped. Make and fit the moving parts. The position of the holes for "E" in each piece is not critical. What is critical is the bends in the wire "F. Try this project with a child, or build it as a gift. Detailed instructions and photographs to make a clever candy dispenser using a pint-sized mason jar.

When you pull the 'drawer' out, it dispenses a small handful of your favorite small candy. It is sure to be a favorite among the kids and can even make a great gift for that hard to buy for 'executive' on your list.
