ive made a speaker housing like a ufo for a project. I want to make a base that spins to put it on. Like a lazy susan but smaller (bit like a spinning wheel) I could then put the speaker onto the spinning wheel type thing and turn it so it spins whilst playing music!! How could i make one the easiest? or buy one cheaply? the speaker is only 17cm diameter and obviously the wheel doesnt have to be that big, just needs a big enough surface area to balance the 17cm on.
