Can anyone figure this out? I want to build a motorized amp rack that rotates at an arc, but the problem i'm having figuring this out is keeping the amp horizontal while maintaining a pivot that it will need to move on the arc. Balance is not really an option and every configuration i can come up with leaves the amp either spinning freely on the pivot, or fixed to it slaming the sides into the ground rather than easing the bottom onto it. It might be simpler than it seems and i'm just overlooking it. If anyone has an idea to get this to work, or even a completely different solution that gets the same results, please help.

try 2 arms with their own centers and attachment to the amp rack. That way the amp should stay horizontal. The sets of arms would have to be offset so they don't hit each other, but I think it will work. I can try to figure it out for real probably tomorrow, just let me know if you need it.

Yeah, it seems like that would work, and it's so simple. I just had my mind set on one arm I didn't even think about it. Thank you.

yep, that's what I was thinking. the simple stuff is sometimes hardest to see, especially when you've already got an idea.

Another option would be to use a geared arm and chain setup. This will eliminate the need to offset any arms or anything. A bit more complex a setup, but opens the arc up to a full 180 motion (or depending on how you build your rack, a full 360 motion)

Could you explain? I only need about 60 degrees of rotation. I'll show you what i'm going for, using the stackable alpine pdx amps...
