@boo Heat the item, add the solder lol. And use leaded, that lead free stuff is naff, I can do everything with a simple 30 watt iron using leaded stuff.

Got the trussrod slot routed, headstock angle done and fretboard glued and clamped. I like cutting the headstock angle wide of the line with the bandsaw then using a handplane to bring it into place.
 

@robin Well done! That is one more thing on my “never in my life” bucketlist…

@robin 👍😃
