Boom Arm (Schwenkarm) Part II - Putting the arm together
Тәжірибелік нұсқаулар және стиль
In this video I am building a Boom Arm for my shop. Commercial arms are too expensive and can't do what I want, so I created my own plans. The wood is mostly scrapwood from the hardware store (top, bottom, bridges 5€, sides ~12€ and wall holder ~3€), the aluminium was bought in bulk, so it's ~3€. The wall arm should be less than 30€ in total later. I will upload the drawings as soon as I have build it, I want it to work before I give those out.

Any feedback on editing and content is appreciated, I am still pretty new to it. I added chapters so you could skip it all, but personally I like it.
There will be a Part III that I did not anticipate because the wall that the arm is supposed to be installed to is too weak. Also, it sags. A new wall mount and a better solution to fix it to the wall are going to be explored in the next video.

Impressive work
What a construction! Nice job. You could potentially make it way lighter by getting rid of none essential plywood parts, and thus reducing strain on the wall support. For instance, usually for cantilevered constructions the most stressed parts are the top and bottom geometries (Ober- und Untergurt). The side panels are only necessary to mitigate torsion and in your case maybe even superfluous, since you have partitioned everything with the tube holding plywood inserts. Additional weight could be shed by 3d-printing those. It's also probably better to leave some play, instead of trying to mount it stiffly to the wall. If the support has a little wiggle room it can adust, it is super stiff and not perfectly designed, it can only break at the weakest spot.

Cool, thanks for the feedback. I was pretty sure I needed the sides. :D Maybe I could take even thinner plywood, without I'd feel insecure about it holding. I might make another one in a few years, for now I am going to create a new mount which will be anchored to the outside of the wall... :D

Okay, after intensive googling I am concluding that because of the Widerstandsmoment the sides are still needed, albeit a lot thinner. Thanks for the great input.
Очень круто!!!!
