Rotating Speaker Mount - Magnetic Position Lock

This is an older project I finished when I was still in University. As always nothing you will see was done in any professional manner because everything was built in my bedroom basically. Still a success as it worked perfectly for a couple of years. Nowadays I have my own appartment and don't need to swivel around my desktop screens anymore.

Finished Project

My computer screen doubles as a TV to watch TV series and movies in bed. The problem is that I had to rotate my speakers (each 5kg or 11 lbs) every night and morning which got annoying really quick because I obviously have to rotate my screen as well.
So I decided to build rotating speaker mounts that lock into position exactly where I need them to. As you can see they are slightly angled upwards when they are facing away from bed and slightly angled downwards when they are facing towards the bed. This is due to the fact that the studio speakers I have sound the best when they are directly facing your ears which is why I simply couldnt buy a rotating plate off the Internet and decided to go the DIY route. This setup makes sure that the sound in bed and sitting at the desk is good (enough for me at least).

Build

As far as I remember it's oak. 80x20x1cm(31,5x7,9x0,4 inch) cost me 8,50€ (roughly 9.5 freedom dollars) and they cut it for free.

The two pieces on the right are the bottom plates. They are smudgy in the pic because I already oiled the other side of each of these when they were used in an earlier, shittier version of the speaker mounts. The bottom pieces are 20x25cm (7,9x9,8 inch) and the top pieces (the two on the left) are 20x22cm (7,9x8,7 inch). I drilled holes in the center of the wood for the bearing swivel thing (you'll see that later). As already mentioned some of the cutting was done in the hardware store I bought the wood at but I also had to use my jigsaw for cutting because I didnt really plan that well. I also dont have a table saw or many fancy tools as Im a broke student.

This is the underside of the top plate (the plates that are rotating with the speakers). I drilled holes for my neodym magnets, 5 in every hole. The diameter of the holes is 1cm (0,4 inch), exactly the size of the neodym magnets which are 10x2mm (0,4x0,08 inch).
I paid 6€ (6.50$) for 50 magnets.

I've gone completely crazy with the amount of 2 component adhesive I applied.
But if you knew how much time I wasted with earlier versions that didnt work because I used shitty glue then you'd understand. Besides that the glue spots arent visible in the finished product anyway.
The glue was like 10€ (11$) but I still have a lot of it left so Im not even mad.

Checking if I drilled correctly and test mounting the swivel bearing thingy (sorry, dont know the english word).

Now I attached both pieces of wood to the swivel thingy and marked the positions I wanted the mount to lock into later on. I simply attached a few more magnets to the already glued in magnets so I would have an easy time marking the position on the bottom woodpiece.

Drilling the holes in the bottom parts.

just checking if the angle is alright

Now the holes in the bottom parts are also done. I drilled another hole in the top parts so I could reach the black swivel bearing thingy to screw down the screws later on.

That should make it clearer

WD-40 gang represent. I had nothing else but it worked fine to make the swivel bearing thingies more swivelly as they accumulated a lot of saw dust when I was drilling holes and stuff. It also would have worked without the oil but its way nicer.

My roommate had some IKEA cutting board wood oil. It worked fine for my purposes.

Before that I glued the magnets of the bottom parts into place. I used less glue this time.

spinny enough I guess. Here you can also see the magnets on the bottom part which I glued in using a smaller amount of glue which also worked fine.

Here you can see it snap into place.
Thank you magnets, very cool.

Now I just had to cut up some wine corks in order to make the mounts slightly tilted. It was kinda hard to exactly cut up two wine corks to the same angle and height but it worked out after a few fails.

Used hot glue for the feet.

here you can see the remnants of the alpha version. As I already mentioned I had already used two of the woodpieces for the same project but it looked shitty and the glue I used couldnt hold the magnets into place so I redid everything. Well but the glue could hold the magnets into place when I wanted to get them out of the wood.
I simply said fuck it and let them inside.
