I have pulled apart many bikes over 20 years and have a good mechanical aptitude
but i am not sure about the chainline and how you line up a front spocket with rear cog
are most popular sprockets/cranks similar offsets?
or will i just have to trial and error with spacers on the rear axle?

Where's the fun in that? I thought it was supposed to be trial and error, a bag full of mis matched parts you found / ebayed / scored from the tip etc., some spare time, some spacers, a spoke tool and a set of cone spanners. It's impossible to take more than 15 minutes to get a working chain line even if you're using re-purposed road parts, as long as you know how to true a wheel and can adjust a bearing cone.
Trial and error FTW!
but really, that's rubbish. We get none of it because the choices are illusory.

Since I keep misplacing my common sense down the shed, I guess I'll have to borrow someone elses off the internet.
