Hellllooooo :) i did plenty of lurking trying to suss out if i had the gumption to see a build through to the end without stalling and wasting all that lovely cash

sounds like most of the hard work is done... if your already designing and cutting in 2D the jump to 3D should be pretty easy for you
and if your thinking of building a cnc you have all that lovely machinery at work to take out the elbow grease you lucky sod (if the gaffer is a good lad that is :naughty:)
good luck
