| i don't want to put you off the idea of building traction engine, but they just don't come cheap, and when you think off the amount of hours that go into a 4" model then it's easy to see why it costs that much.
so far my 3" engine has taken so far nearly two years to build and it has cost over £1000 most of that was buying the copper for the boiler.
if you are really interested in biulding a traction engine i would suggest a smaller model, for example MJ engineering do a 2" burrell gold medal tractor. most the parts are quite cheap and if you don't think you can machine a certain part they will, but at a cost.
hope this helps
