Hello everyone! This is an Instructable of a new ball machine lift, the Alternator Lift! This is a lift I made and worked on for a month. Here's how ...
These are all the parts you'll need to build the Alternator Lift. Rods: 617 green-200 white-123 blue-200 yellow-76 red-10 ...
Before you begin on your quest, you need to see this step. The first picture shows the many sections that you'll be building. The second shows what si...
To begin with, you'll build one side of the tower's base. The side with the connectors that have green rods on them is the front (this goes for the wh...
Here you'll build the other side of the tower that complements the section you made in step 3. It's the left side of the tower.
Now you'll attach part 1 and part 2 together to form the tower's base.
These push the balls up. They will attach to the lifter, which will go up and down to grab the balls. First, build the normal grabber (pictures 1-4)....
This is the lifter. It will hold the grabbers. Build it.
Now you'll attach the grabbers you built in Step 6 to the lifter. You'll also need 6 blue rods, which connect in between the grabbers.
Now that the lifter and its grabbers are complete, you can attach it to the tower's base. The blue rods sticking out of the bottom of the lifter will ...
Here you'll build Part 1 of the tower's middle section. It'll be on the right side. The blue rod connected to the trio of red connectors will also be ...
This is the other side of the middle of the tower (the left side).
Combine Parts 1 and 2 together to complete the tower's middle section. They only connect in two places, in the bottom corner. Then you will complete t...
Now you'll combing the tower's middle to the rest of the model. Remember to slide the thing in the back onto the gray rods (refer to picture 4). Also,...
This is Part 1 of the Top. It'll go on the left side.
Build the right side of the Top.
This is the final part of the tower's top. It will hold the string that lifts the column up and down.
Here you'll combine what you've built in steps 14-16. Pictures 2 and 3 show Parts 1 and 2 combined. Pictures 4 and 5 show Part 3 added.
Now attach the tower's top to the middle.
This support will attach to the left side of the tower. Build it, and then attach it.
These are similar to the ball grabbers, except they don't go up and down. Build three normal holders, and attach one to a different kind of holder (pi...
Now you'll connect the holders to the front side of the tower. Make sure the holders rest on the green rods.
These supports go on the sides of the tower. The one with a white connector at the bottom goes on the right side, and the other one goes on the left s...
Now you'll begin the entrance where the ball enters the lift.
This is a track piece. It's broken up into two parts so it's easier for you to build. After you build it, you'll combine it with Part 1.
This will fit underneath the track, and will push balls into the lift. You'll need a rubber band for this step. After you build it, you'll attach it t...
This is a piece of track that the ball will go on before being picked up by the bottom grabber. After you build it, connect it to the rest of the entr...
Now you'll attach the entrance to the front of the tower. Make sure to connect all the rods to the connectors.
This piece of track is where the ball will exit the lift. After you build it, attach it to the top of the tower.
This will support the back of the lift.
Now connect the support to the back of the tower.
These are two small wheels that the string will go through. Build them, and then attach them to the back/top of the tower. The yellow rods should be s...
This will complete the back support. After you build it, attach it to the back/base of the tower.
This part of the motor section will hold the red battery pack.
This part has the motor and gears.
This is the third and final part of the motor section. It has the crank and rubber bands.
Now you'll combine all three parts together, and then attach the whole section to the right/base of the tower.
Get the string. It can be any kind, as long as it isn't stretchy (I used fishing line). Make sure it's the same length of what it says in the parts li...
Here you'll put the string onto the lifter. You may need to remove a few rods to reach in there. Then, put the string through the four wheels (pictur...
First, get a dark gray connector. Attach it to the crank (picture 2). Also, put the crank in its uppermost position (picture 2). Then, tie the string ...
You're almost done! Just build the ball pusher, which will push the ball to the exit when it gets to the top. Then attach it to the top of the tower.
Congrats, you are now done with the Alternator Lift! Now go add it to a ball machine, or turn it on, add balls, and watch it work! If you use it in a ...
