After a while you get the 'flow' of where things go and what you have to do NOW to get those things 'there' later....example is antenna tube, radio installation; switches, etc. I like to decide as much as I can before I even start construction then write it in the manual. Blind nuts can be installed long before the part gets glued on, switch backing in plywood is done before the fuse is completed....etc.

It takes time....and trial and error
