How do you make a model fairground ride?

There are many ways this can be done, as. some models I have seen, even on modelmakers web sites are quite crude. You can knock up a model on a piece of old plywood, and leave a lot of the detail out for quickness. then paint it with old enamel paint that has been lying around in your shed for years, and you will finish up with something that will look pretty amateurish.

I invested £35 on a set of 1:24 scale waltzer plans which is a complete miniaturization of the real thing, and can be dismantled from a trailer, and built up as it would on a showground. My model is up to the outer platforms, being stuck now due to my wife making me unscrew my lathe from the utility room table, rendering me unable to knock up some little turnings for bearings. So it's been in progress for 2 years now. I could do it quicker by not making it so it builds up, but that would defeat the object of making a model. The real pride lies in the detail.
