Ok im going to summarize the parts so far.
Im building a wooden constructed belt driven plotter using these parts from:
http://www.ebay.co.uk/itm/CNC-Kit-3-...item2a14d75139
i need to choose the correct belt size as in width i take it i can use smaller belt for
the shorter Y and wider for the longer x ...say 10mm / 25mm?
15 tooth pulleys ok?
Are these steppers man enough?

3M pitch belt driven with 15 tooth pulley gives you 45 mm of axis movement per revolution of driving pulley. Reducing it further 5x gives you 9mm/rev. Driving it with stepper (after reduction) @1/2 step (400 steps/rev) gives you 0.0225mm resolution. I think its enough for your boat drawing or even for cutting
Driving it directly with 15 tooth pulley @1/2 step will give you 0.1125mm resolution
