Thanks! Will give that a go before resorting to facing. Cranks look a little too chunky but I was drawn in by the range of possible chainring sizes and axels etc.
Might try and find a set of the old Dura ace cranks that look so nice on the Fern builds:
Headset/spacer stack is gold.
I had binding issues as well and used a couple of thin shim washers to lift the to bearing cover away from the head tube.
Bike is starting to look great.
