Introduction: Knex Parallel Arm Lift

Here is my newest lift: the Parallel arm lift!
Most credits go to Shadowman, as he invented this lift first in his unfinished ball machine, I tried to rebuild it from the vid (only managed to rebuild the front part of the arm and some basic ideas).
So, this instruction is very complicated and nothing for absolutely beginners.
And it is also loooooooooong.
Be sure that all 3D connectors are turned correctly, with some you also have to pay attention that they aren't turned 180°, I'll note which in the image notes, so be sure to read them!
Sorry for any fails I made, making instructions was quite complicated.
And feel free to ask if you have any problems!
I use a plug-in motor, and I would recommend also using one as they have more power than the battery motors. Maybe you could use two battery motors...

Oh, and the first one to make a piece count will earn a patch :D (But please be honest about it)

Step 1: Making the Left Base

Just some structure...

Step 2: Gearing Part One

Be sure to make spacers etc. correct

Step 3: Gearing Part Two

Step 4: Gearing Part Three

Step 5: Gearing Part Four

Step 6: Gearing Part Five

Step 7: Gearing Part Six

Here's also the motor

Step 8: Gearing Part Seven

Step 9: Attaching the Gear Box

Few, finally gearing is finished!

Step 10: Making the Right Base

Step 11: The Entrance Track

Step 12: Connecting...

Step 13: The Gate

Step 14: The Lower Arm

Step 15: Back Counterweights Tower Shaft

Step 16: Front Counterweight Tower Shaft

Step 17: Arm Tower

Step 18: The Exit Track

Step 19: The Arm Connection

Step 20: The Arms

Now you'll make both arms, later on you'll modify them as they are unique in the model.

Step 21: Modifying the First Arm

Step 22: Modifying the Second Arm

Step 23: Making the Top Wheels

Step 24: Making the First Counterweight

All Y-connectors are just clipped onto the end of the rods.
The string between the counterweight and the connections (without the used for the knots) is 1.43 meters (56.2992126 inch).

Step 25: Inserting the First Counterweight

The red string indicates where it will go as it is hard to see.

Step 26: Some More Modifications for the Second Arm

They weren't possible to make before

Step 27: Making the Second Counter Weight

It is actually the same as with the first one, just somewhat shorter.
The string is 86 cm long (33.8582677 inch).

Step 28: Inserting the Second Counterweight

Step 29: Finishing the Crank

Almost finished!

Step 30: Finished! + Troubleshooting

Wha, you'r finally finished!
Sorry for all mistakes I made, making the instruction was REALLY complicated. I also had many problems with uploading so many files at the same time to ibles, and then ibles also didn't sort the files correctly in my image library....
Well, but here it is!
If you add a picture below of your model I'll ad it to this step!

Troubleshooting:
My arms go as choppy down as in the beginning of the vid! - Make sure that all the string is correctly on the wheels, that was also my problems with the first clip and I was to lazy to re-film :P

The balls won't enter the lift as the gate won't go up! - be sure that that thingy in the back of the gate is in the correct position.

The balls fall back down when going to the next arm! - The 'trapdoors' have to be swiped over the hole.

My model doesn't look somewhat correct! - Make sure that every rod is attached correctly.

My model looks very crashed! - Next time don't through it out of the top window of a three story building!

Hey Sorunome!, i like the lift! i`ve build it it does work now! im going to use it in my ballamchine! :D

author
Sorunome (author)cooljupjup2014-02-14

yay, awesome :D

author
knexman32 (author)2013-03-28

is it ok if you use the smaller wheels instead of the bigger ones?

author
Sorunome (author)knexman322013-03-28

I would not recommend that as I use the wheels as a counterweight and the bigger ones weigh more. Maybe you could make your own counterweight that is about same heavy.

ok thx

Hey sorunome!

This is a very good lift: high, good looks, works good,...
So... I've built it!
I know you didn't invent it, it was Shadowman.
But congrats for rebuilding it from the vid and making good instructions.
I'll use it in my next ball machine, where I'm currently working on.
Here are some photo's, if you want you can add them to the last step of this instructable.

The Jamalam (author)2012-05-16

An excellent mechanism, my only concern is that the motor sounds strained. I can imagine with the mass of the arms this will be hard to avoid but perhaps if you were to guide the pulley so that the line of action was parallel with the ground you'd get a more even lift? Just a thought.

author
Sorunome (author)The Jamalam2012-05-16

I don't quite get what you mean but I bet if you'd make this lift twice and connect them correctly it'll run very smooth.
Oh, and thanks :)

author
Shadowman39 (author)2012-05-11

Cool! How did you make the degree sign in the intro? I still think the counterweight should be heavier (the one that moves faster). Is that the tall ball machine I see to the left of it in the video? :-)

author
Sorunome (author)Shadowman392012-05-11

Thanks!
And there are a lot of reasons why the faster counterweight isn't heavier, in first place because it won't work anymore.
Yep, that is the fast ball machine.
And in the german keyboard layout, dunno if it is the same with the us one, I get the degree symbol by hitting shift and the key below Esc.

author
Shadowman39 (author)Sorunome2012-05-11

Oh the degree sign is also in the rich editor. :-P We don't have degree signs on our keyboards.
