how do i make something spin? (help please)

Found 24th Nov 2009
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.

no its not liek that.. it doesnt play records:oops: it plays off ipods etc. Anyqay basically all i need is a base that i can put this on (make/buy) that i can attach and spin. no electric motors or anything involved just pushing power.

someone must know what im looking for? :l
how will you manage with the cables geting twisted when the speaker is spinning?
Maybe the mechanism from a childs spinning top toy?

i must be explaining this really badly.
the speaker is already housed.
i am now looking for a seperate board (base) that can spin. ie 2 pieces of wood with a bearing in middle. Ill then just put the already housed speaker onto the base and spin it. Pretty simple.

use a router to route out a circular groove in 1 piece of mdf. put ballbearings into the groove (they would need to be slightly bigger than the depth of the groove. drill a hole in the middle of the bottom mdf, cut out a circle of mdf with another hole in the middle, insert a metal rod or something to create an axel. plonk the circular mdf on the rod and hey presto she spins

i only want the spinnign mechanism (bearings) and i will add my own top/bottom in mdf or plastic. so preferably just that rather than a whole board like the above argos thingy.

no fill the groove with ballbearings and just use the metal rod as an axel to pivot the top mdf on

exactly like the lazy susan

wait i think i got it, if i buy a bearing liek a wheel bearing is one side still (attach to bottom) and the otehr side spins allready (attach to other side) resulting in bottom staying still whilst the top spins around? prebuilt like that?

you see the silver bearing here, is that how i would buy it? obviously smaller because my thing is only 17cm diamater
