- I used to have a lot of trouble with bar lifts, so I compiled a guide to the tips that helped me make efficient and stable bar lifts.

Dude, this is beautifully done. Love the ending too. There's very little good educational content for rookies that I've come across.
Thank you so much, I would not have been able to make a good 8 bar without this video.
Thank u for these. This will be our first year with VRC. And these videos will help us learn!!
Your a life saver, I’m trying out for vex and this is a really well out video:)
Who’s watching this for school?
Extremely helpful for a vex noob like me. Subbed
Teams in tipping point found this video extremely useful
very cool, never used vex before but lego and some electronics, seems like double wishbone or live axle suspension is possible with vex then :D
Where do you get the bars themselves? I've gotten pretty decent at the robotics themselves, but I'm struggling to find good construction materials.
You don't need to use nylocks, you can just tighten a keps nut a lot. It makes it so much easier to assemble and disassemble.
Also at 1:56 if you put those three hole spacers on the inside of the c channels you would save a lot of space.
but otherwise very good, I guess what type of nut you use depends on your preference and what it needs to do
I've heard of this method, but I have yet to try it. This is the method I've used, and it has worked extremely well. Now, it is not the "perfect" solution, but this is a solution better than the things that first come to an inexperienced builder (I would know, I was once one) :)
I plan on trying some of these ideas in the future, but I haven't gotten around to it yet.
I agree your methods work well and are sturdy. Much better than most
Thanks, I appreciate the constructive criticism :)
And keep things as physically compact as you can. Stays stronger that way.
What kind of screwdriver are you using?
Where will i get this steel or aluminum bar lifts? Can U provide the link?
Is it just me or does he sound like matpat....
No? Just me? Oh...
Also thank you so much for this video, it really helped
Well now it’s ruined
No he doesn't
I was like omg is this mini matpat? To me he sounds like matpat
How high can the 6 bar you built in this video go? Thanks!
I don't have it built right now, but it is a good thirty inches or more.
How about the double four bar
Like one four bar and a reversed four bar(which is facing the other way) so there will be no swing
I decided that the DR4B would be plenty for its own video, as there are a number of things that make the building complex and harder to follow. I thought that rolling that into this video would make one really long video, and that would be more confusing for new builders.
can you do a double reverse double 4 bar lift - using an electric actuator - has anyone seen this?
i did a double reverse 4 bar in 6th grade, im searching trying to remember how to build it
Can you please give me an example on how you would use it with an object? I am confused on how you would apply this to your robot. How would the lift hold it?
You’d have to add some sort of instrument on the end, whether that is a forklift type thing, or some sort of claw.
@@KeplerElectronics Thanks! That makes more sense!
Aren't these just scissor lifts? Are there any differences?
Scissor lifts have one point that is attached, and another point that is moving (like a linear slide), and by moving the points closer together, the lift moves up. Whereas the bar lift has two bars that are stationary, and by rotating one bar, the lift extends. Also, a Scissor lift is usually mounted parallel to the ground, whereas a bar lift is usually mounted perpendicular to the ground.
Kepler Electronics I want to see you build a robot with a scissor lift instead of a normal 4 or six bar 😂
I do vex
0:28 common miss conception it’s actually called a 4 bar because there are 4 parallel bar 2 horizontal and 2 vertical and this holds true for all bar lifts also you’ll find less friction if you put a nylon/teflon washer between the screw head and the c channels or just in between any 2 pieces of metal that are rubbing against each other also use nylon spacers instead of nuts when spacing out screw joints for reduced friction 1460G
Shit thanks Kepler electronic
0:30
This video saved my parents marriage, they still beat me up lol
Tech Grid Gaming r/wooosh
TanKT1ger a wooosh is when somebody doesn’t get a joke, so yes, it applies
TanKT1ger Ooooooooooooohhhh, I apologize, the wooosh is in me
TanKT1ger welp this is awkward
Quinn McGinley there’s an edit feature
This dude sounds like datto
That is just not a good way to attatch the bars on a lift.
If you have a better method, feel free to let me know. I've had great success with this method, and I haven't seen a method that achieves a good balance of stability and low friction.
Kepler Electronics At each join you should only have 1 bearing the other c channel you do the nylock up fully tight to the channel with the screw on that channel and then put the slightly loose on the other side of the bearing which you should put on the inside of the channel. And between the bearing and that loose nylock you should have the smallest nylon spacer and you tighten that nylock until that spacer starts to become slightly difficult to spin. It's lighter as it has one bearing and so also less screws, it is more stable as at each joint you only have one place on the screw the joint can move and not two and with the spacer you can get the friction perfect and it makes no difference to the friction having one bearing not two.
Thanks for the heads up, I'll have to try that sometime.
Kepler Electronics I can make a quick vid comparing our methods and put it on my channel if you would like
Feel free to do so, I look forward to the results :)
The URL to this video has gay in it. *cough* *cough* Kepler's gay *cough* *cough*.
This may be a joke but u will never know for sure.
