Big Bites
Here's something of a counterpoint to "little bites".
Since the wings are actually a relatively small number of very similar parts, ribs, for instance, and the second wing will progress nearly twice as fast as the first because you know the road, consider batch processing of terribly repetitive tasks, like deburring. This will avoid the dreaded deburring burn-out. "Man Jailed After Beating Inquisitive Pedestrian With Wing Rib."
'frinstance, gather all the ribs for one wing. This makes you learn the distinguishing characteristics which can be subtle. Then dedicate two hours to standing in front of the 6" wheel and deburr the lot of them. It's done. Take 1 hour to deburr the lightning holes with a two inch wheel in a die grinder. It's done. Then flute the lot. All the production steps take little time in the aggregate, but it feels like forever if you dabble forward then retreat to the same process again.
When you drill/c'sink for the spar dimples/platenuts, do the whole spar at once (two hours, tired muscles). Here, studying plans so you understand the differences along the spar are where you must spend the most time, and where you will likely feel overwhelmed at first. Time leaning over the pages and time to fabricate/assemble are fairly even.
There's sure to be disagreement on this, but here goes. Final drill the holes in sheet metal, spars, and ribs prior to assembly. You aren't going to relocate a CNC hole one iota. Particularly when a flat sheet lies atop a flat sheet, like wing walk doublers under the skin, you are perfectly safe pre-drilling.
The second wing will go so fast, you'll wonder why the first took as long as it did!
You will finish it. No deadlines. Just right.
Some of my crates became a chicken house. One board with "UP" and an arrow is alongside the perch so the birds remain oriented.
