Removed the spars, stringers & wing jigs from the box today, I'll leave the work bench at its present height until I have all the ribs, spars & stringers fully prepared for assembly, just to save a bit of strain on the back. A couple of issues I have noticed so far - one rib mounting hole is not fully formed in the main spar, I'm seeking factory advice via email on a remedy - the bolts supplied to attach the root end of the main spar (the wing's main attach fitting) to the jig are over size in diameter, I don't want to force a steel bolt through a close tollerance hole in an aluminium part - some of the wing jig parts seem to have been incorrectly labeled causing me a bit of head scratching.
