Introduction: K'nex Hammer Lift

Hey!

This is my new (and first) k'nex lift system. I came up with this idea, because the physics teacher was showing us the effect when anything that's heavy (a hammer) hits a light - weight thing. (a small ball) So I made that system with k'nex, and this is the result.

In this lift, a rotating arm goes up, and it comes down real fast, sending the ball up the incline.

The one in the video is a bit different, the one in this Instructable is better.


Hope you guys like it.

Step 1: Parts List

These are all the parts you'll need to build the Hammer Lift.

Rods: 221

green-74

white-69

blue-54

yellow-21

red-9

tan rigid-1

black rigid-1

Connectors: 154

dark gray-14

light gray-13

orange-14

red-10

green-7

yellow-44

orange tube connector - 6

white-3

blue-21

purple-29

Other: 122

blue spacer-48

silver spacer-42

red gear-3     

blue/tan gear-1

small grey gear-1

tan clip-3

blue clip-15

Y clip-14

small wheel band-4

rubber band-1

chain link-7              

battery-powered motor-1

Total: 533



And,  of course, you'll need k'nex balls and tubing

Step 2: Base

You'll start with building the base. It's pretty easy.

Step 3: Right Tower

Again an easy step, next step is harder (finally...)

Step 4: Left Tower

Yeah, a harder step :). This side contains the system that block balls, and let every time one ball pass.

Step 5: Motor

This is a hard part to make, look closely at the quantity of spacers.

Step 6: Hammer

You're nearly finished! Just make the hammer: It's easy.

Step 7: Finished!!!

Congrats, you're done with your Hammer Lift. Here are some tips:

1. The new k'nex balls (the big ones) comes higher than the old ones: If you use them both, be careful at the top of your hill: the big balls could fly off the track.

2. Attach the track as much as possible, this is to save speed, and to reach higher. Also support the track  good: It mustn't be unstable, the balls slow than down quickly.

3. If the arm goes stuck on the system that let 1 ball / time go, make the second and the third picture.

4. If the balls are going to be launched off the entrance path, make it longer. If the balls don't pass, wait till other balls arrive. That balls will push it trough the system that block balls.

This is a cool design! I have an idea that I might use to make it whack the ball even harder and up a higher track by using some of my modified motors which plug into a wall outlet and spin two to three times faster than any other knex motor! :)

i made the project and it works great i never thought that the small engine would never pull that hammer all the way around. i wish you would show how to make the rest of the track.

I can't add a pic now, because I use the lift on a other way: as transport. The ball gets now hit by the arm, and flies 1M trough the sky, and ends up in a basket.

Can you post an instructable on how to modify that to fling the balls that far? I'm definitley going to build this and use it in the new ball machine I'm going to start tommorow! :)

author
RNB made it!(author)2011-06-16

I just see, it isn't 1 mile, it's 1 meter :-P. It's easy: Build this instructable, and don't add more track then shown in this Ible. Just cut the tubing off after the short part shown here, and let the balls fly! If you put the lfit also a bit higher up (so add a red box underneath it i.e.), it will go even further.

So, don't modify, just don't add any more rubbish after the lfit!

in the last step have I put some tips how to make the track. I think you can build your own with that.

Might build but heres 3 questions....

1. Do you have to have that pathing, can I change it to some different pathing?

2. I have the motor in the picture (Ignore ball) will it still fit in?

3. The motor isn't too powerful, does it have to be a strong motor?

Thankyou, MM8

1. It's changeable to yellow 5 - way connectors, although you'll have to find out the new height of the track.

2 + 3 Attach the motor to a white snowflake connector, and change the spacers/rod. The motor should work, cause my motor is weak too. If it doesn't work, just gear it more down. (again a blue gear on a red, you could change the red gear into a big yellow one, but the motor must be on a different place then0

Aww man.

Don't have all the spacers :(

Do you have to have the orange tubing connectors, I have none

Ps: Please reply ASAP

Oh yeah forgot!

Sorry

I decided to make this and it works great. Although I did have 1 problem with it letting only one ball in at a time.

author
TigerNod made it!(author)2010-11-12

A very innovative lift design, I must say. Does it automatically reset itself too?

author
RNB made it!(author)2010-11-13

Yes. It works as long as the motor runs.

author
Purple+Waffles made it!(author)2010-10-12

I built it and what happens is the hammer comes down but stops short of the ball, then comes down slowly. Also, the gate opener keeps breaking when the hammer lifts the thing up. Please help!

author
RNB made it!(author)2010-10-12

Hammer comes down but stops short of the ball??? Could you give me a picture of that, I never had that problem

Gate opener: did you make the 2nd and the 3rd picture of the last step? that should help. It works even better if you remove the blue connector and the blue and gray spacer on the white rod.

If you've more problems, tell me.

So could the track go vertical?

author
RNB made it!(author)2010-10-10

I never tried that one, I'm sorry.

author
Michaelgoode made it!(author)2010-10-11

Ok, maybe a test for me sometime

author
RNB made it!(author)2010-10-11

Please tell if that's possible (if you sent me pictures, I'll add them to this Instructable)

author
Michaelgoode made it!(author)2010-10-09

Oh, its a good design, a similar thing could be made, but the track goes vertical up?

author
RNB made it!(author)2010-10-10

No. Like you see in the picture, the track goes 30/35 degree up, but it has a other use: transport. Just cut the tubes off direct after the "launch" part (the part in this tutorial), and the ball flies about 1M, where it must be saved by a basket.

author
Michaelgoode made it!(author)2010-10-09

Is the end of the hammer really heavy, so it comes down faster?

author
RNB made it!(author)2010-10-09

yes, it's heavy: but not too heavy, otherwise the engine wouldn't pull it all the way up.

author
Michaelgoode made it!(author)2010-10-08

What makes it come down real fast? (the hammer)

author
RNB made it!(author)2010-10-09

Gravity :-)

Sorry but I don't have a lot of KNEX. My birthday is soon and this is number 1 on the list to make. You literly inspired me to make ball machines so you get V.I.P. on my list!

I can't make it but it looks awesome!!!
