My lathe, and possible new build

I mentioned on here a while ago about a machine I was designing and building for removing rubber from tyres. Its now done and the business is running from it - www.midlandtyreshaving.co.uk
The thing is I want to make another smaller quicker machine that I can take to site.
I have a sliding head lathe in my workshop that is a spare to another a matching machine, most of which runs on hydraulics, does anybody know much about hydrualic sytems? I have all the bits sat there to do the job, it would save me a fortune if I could use some of the spare machine! Any ideas?
