First build EXA-1

[rhyd]

Hey up - FINALLY started my build today after an 11 month wait...

Decisions made so far:

• pick ups - swapped out the supplied pick ups for a ToneRider Octane (bridge) and Rocksong (neck) pair.
• finish - settled on idea of a Danish Oil and Beeswax polish finish for the body and the neck

Today:

• did the mock build as per the instruction manual
• checked the neck with a notched straight edge and made 2 anti-clockwise turns on the truss rod to undo the convex bow then read pro-tip saying "no need to adjust truss rod now" - cursed a bit
• clamped the neck in place to check the scale length but somehow missed the key point to check the distance between 12th fret and bridge

Tomorrow:

• re-clamp neck and properly check the scale length...
• check the frets as per page 15 in the instruction manual
• start sanding body and neck

Questions

1. when should I glue the neck to the body? The instruction manual leaves it open for me to decide... part of me thinks glue it in now and make sure it's right before applying oil/polish - any advice/recommendation much appreciated.
2. I've seen a few YT videos where people use a 'wipe on poly' to protect/finish the body after oiling - am I making a mistake by not doing this?
3. on my Les Paul's tune o matic bridge, the adjustment screws face the tailpiece but this stewmac article says they should face the pick ups/neck - who's right or doesn't it matter?
4. should I swap the plastic nut out for the optional bone nut I ordered now or can I leave that until later?
   

Cheers!
