Intro: K'nex Marble Machine Elements Official Guide
Hello everyone!!! Welcome to the first K'nex elements guide for MARBLES (at least on Instructables). That's right!!! It IS possible to make elements for marbles (specifically Magnetix marbles I used shown in pics 2 and 3). These can be just as great as elements made for regular K'nex balls. I created this guide in tributes to my unfinished marble machine Perplexity that was being constructed since it was demolished due to a horrible accident. Nevertheless, I managed to take the time to take pictures of elements planned for use in the machine. ALSO, remember to look closely at each picture to check on something that looks unknown. So without further ado, have fun building these elements!!!
Step 1: Basic Path
Starting out with what the title of this step suggests, this is the most basic tool needed for simple transportation of marbles moving throughout a machine.
Step 2: Red Connector Path
Basically the same type of path that works for regular K'nex balls but make sure the red connectors on the yellow rod touch each other so that the marbles can roll easily and not fall through. This can be useful for catching flying marbles.
Step 3: Basic Path #2
Another basic path with slight modification in fact that it uses black Y-connectors. This is taken right off of my own specially designed marble separator/bottom-of-lift shown in a later step.
Step 4: Freefall Tube
This element allows for marbles to have a perfect freefall onto a designated area like pathing. It also it used as a path to 100% guarantee the marble stays on the track. The marble drops down the middle.
Step 5: Red Connector Path #2
A path where marbles roll on top of red connectors and takes up less space.
Step 6: Four-Marble Dropper
Exactly as the title suggests, this arm will tip over when four (Magnetix) marbles land on it. The blue clip was added in between the yellow connectors to better separate the marbles as they roll off.
Step 7: Simple Alternators
When marbles land on these alternators, they will slightly tip over as marbles roll off usually onto other alternators which looks cool in rapid succession.
Step 8: Path Shuffleboard
This is key to building a marble machine with multiple different paths. Make sure this shuffleboard tilts accordingly to what is seen in the pictures. The last picture is a view of the bottom.
Step 9: Fall-Through Path
This element has marbles moving along a pathway that expands until marbles fall through, then land on another expanding path and so on. Warning: This element is extremely difficult to set up. Red rods that bend down are hard to get to stay in place. Blue flexi rods can be used in certain areas if it's easier to do.
Step 10: Chain Drop
This element involves a chain that has a claw with a counterweight that lowers marbles that land on it and rebounds completely on its own. 17 chain links will be needed for the chain drop shown in the pictures.
Step 11: Flipper
A marble will land on either side and will be flipped directly underneath the other side, it looks cool with multiple flippers in rapid succession.
Step 12: The Maze
This rather tall element can use multiple marbles at once. As the marbles fall down this chute, there are rods and connectors on the inside with failures in between for which the marbles can slip through and have a slower, more interesting descent.
Step 13: Panel Maze
This element is much more limited than the regular maze in the previous step but easier to build.
Step 14: Alternating Arms
This unique element has two arms attached by a chain and a gear that has the two arms move in opposing directions when marbles land on it.
Step 15: Down-Up Arm
When a marble lands on the part shown in picture 2, it goes down, then up, and rolls to and falls off the other side.
This element was created from the person who invented this element, sandroknexmaster.
Step 16: Spiral Bowl
What marble-related contraption would be complete without including at least one of these spiral bowls?! This classic element I was able to design simply sends marbles "spiraling" toward the middle.
Step 17: Pendulum
Another element made by sandroknexmaster which I redesigned for marbles. A marble will jump into the pop-out track, flip the arm upside down, and have it act like a pendulum until the marble falls out and rebounds back, hence the name of the element.
Step 18: Marble Separator/Bottom-of-Lift
This is only for if you intend on making a marble machine. This isn't really an element at all, but rather a mechanism for making sure marbles get properly lifted by a chain lift without falling off.
Step 19: Chain for Lift
Same as before, this is only for if you want to make a chain for a lift in a marble machine. The chain doesn't have to be as big as mine, as it depends on how tall someone's certain lift will be.
Step 20: The Letter "P" (Bonus)
I made this since my machine was called "Perplexity" and started with the letter "P." Just thought I'd share this as a huge thanks for checking out my guide for marble machine elements used with Magnetix marbles. Hopefully this guide will inspire other's to build more marble machines so that there is more of them just like regular ball machines which would be great!! Thanks for viewing and have a wonderful day!!!
