How To Make The Time Rotor Spin

It turns out my dad is pretty serious about getting something to make the rotor on my tardis spin (see my console build www.tinyurl.com/ripintime)

I was wondering if anyone could suggest something that would be good for the job that is relativly cheap.

I expect people will be more used to making things go up and down and not spinning around but if anyone has any ideas i'd like to hear them.

Thanks

depending upon what your trying to spin something like ( http://www.maplin.co.uk/Module.aspx?ModuleNo=9882 ) might do the job...

This is what i am trying to spin and it is quite heavy but i will look into that ^

Thanks

if it's mounted on bearings and designed to spin then a disco ball motor should do it... if not then try mounting it on something like ( http://cgi.ebay.co.uk/3-Lazy-Susan-Bearing-Swivel-Only-2-25-Each-/150533734854?pt=LH_DefaultDomain_0&hash=item230c8281c6#ht_957wt_1030 ) and it should be ok :)

It will very much depend on:

How heavy it is.
How tall it is ( will affect how strong the bearings need to be (to stop it tipping over) ).
How fast you want it to spin.
What you would like the motor to run on ( e.g. 12v 24v etc. ).
How much money you are willing to pay for the motor (will affect the size , weight, shape etc. of the motor).

From the looks of your build, the easiest way to spin it would be to mount a rotisary motor under the panels with a small wheel attached.  Make the wheel contact the base of the cabinet and use a small amount of pressure exerted on the wheel, against the base of the cabinet, and it should spin.  This is assumeing you have the cabinet on a lazy susan ring.  When you purchase the ring, do not buy the biggest diameter that would fit your cabinet but rather as small as possible to reduce the friction.  Too small and the rotor will wobble.  I use a similar system to make my rings spin on my console.
