Ball Machines, Lifts and Elements / K'nex Plate Wheel Lift

K'nex Plate Wheel Lift
--> View Instruction



Hey y'all

This is a very simple but good looking wheel lift that I used in my ball machine 'Emotion'
The construction is very simple, doesn't require a lot of pieces, and works with other types of motors too. The balls get raised by 3 blue rods, or 1.5 red rods.

If you have any questions, as always, let me know.

Hi is there anywhere where I can get the parts listing for models. I have the Cape Canaveral kit (12526/10897) and want to check the parts it should have. Thanks for your help

Try keeping them below 50M

not sure what the forum is configured for, but that is the limit on the proxy. time to check the forum config

Do you have an approximate piece count? I was wanting to try some design concepts on this, but it is extremely advanced. Would it be possible to combine a 2D printer into the same unit?

The injection molded K'nex pieces would need to be heated to 360 degrees to melt it into a base plate. It would be much easier to place the base plate's mold under the extruder, but then the base plate would have the same melting point as the filament. Polypropylene also has a high melting point (can also be boiled), but would be more than 100 degrees less.

Yellow 5-way connectors sliding along each other would not be very smooth, as the tops of connectors are usually not flat. It would be smoother to slide along a long rod through a connector. For the design in image 5, if the yellow rod the wheels spin around can be anchored with a 1-way connector that allows free rotation and clips to a rod at the center of the yellow connector, that would reduce the resistance. The motor can be 12 or 24 volts, just depends on the power supply.

Same thing happened when I tried publishing a completed build. It had an error, even though the size of the images was below 65536 kilobytes, and it is stuck as unfinished (orange in the list), and cannot even be deleted. Another time when uploading images to a poll, there were no images afterwards, even though they were uploaded and were less than 64 megabytes.

May be that I'm uploading too many at once. Going to upload them a few at a time

How large are the photos? They might be too large
