Prototype 'Noga' Articulating Arm Build Episode 7 - Assembly & Design Discussion 

Solid construction! If everyone accepts this, I think this design will be created. Please continue to prioritize yourself.

Great Build, we have all had the days when things just don"t go:)

Thank you very much for sharing your knowledge and skills. Excellent work, very pedagogical. I look forward to your next project.

That’s a lot of work man good luck and god bless you

I would love to have the plans for this awesome project 😁

very heavy dutty Arm..good job..thanks for your time

Well done!

I think it turned out great, it's definitely nice and Skookum that's for sure. Now the only thing that will cause camera shake is an earthquake lol. The only thing I'd change/suggest would be the addition wing nut or a knob for the pivot point to make adjusting it quicker and easier other than that I think it perfect! 👍👍

it would we cool to see a hydraulic version of the arm built is there a video on yt that shows how it works I had an idea if you put a gas shock (the kind of cylinders that are used on the trunk of a car for example) in the the id of one of the tube and have it constantly apply pressure to the ball/ swivel joint via a rod with a sliding fit in the id of the tube and a hole and bevel at the front . the default status would be a locked articulation/swivel point and to release it you could maybe utilize a tapered hole in the "rod" (the component with the sliding fit that bears against the ball) and have a screw with a tapered point that is slightly misaligned by .1 to .2 mm. my english is failing me but basically the screw with a tapered point would release the clamping effect on the gas shock by engaging with the taper in the rod and allow the the joint to articulate till it is backed out again if there is something you don't understand or id didn't stated clearly enough let me know

Fabulous project. Thanks you for sharing such a simple, yet sensitive and complex mechanism to machine at home. 👍👍😎👍👍 As you stated, I too suspect the ID clearance did not remain smooth after welding. I wonder if you could have been restored the ID’s with some emory strips threaded into a long thin slotted mandrel installed into a drill chuck.

Enjoyed the build, thanks for sharing..

Very cool….thanks

I think if you decide to build a version 2, threads+loctite would be the better way to go rather than welds and push fits. Also, you may need to heat treat the spring clips after forming them. If they're still in the annealed state they'll just deform when you strain them. Still, great project though.

Time out?!? You said there’s designs for similar arms using closed hydraulic system?!? Link to examples please!!!

How much you want for that prototype? I just want to hold up a 15.4” monitor.

What did you thread on the boat at the elbow?

You do all that nice machining why the hell do you force it like that... Welds cause a choke point, turn it down! Don't hammer it home wtf
