Salt sounds like genius..i've been using small brass pins driven into the face of the join and clipped off. Thanks for the wisdom.

Fretboard fret markers:
Guitar picks- pearloid
Single hole paper punch
1/4" drill bit- drill press if available
Drill down a hair past the tip of bit
Use wood glue in hole and press in punched pieces of guitar pick.

I use sticky back silver mylar.  About the thickness of aluminum foil.  punch it out with paper punch, peel the back off and stick it onto the fretboard.  The adhesive is strong enough that I have only had one come loose after building 26 instruments.  Plus no drilling into the fretboard.  The disadvantage is that this stuff is difficult to find.  It is used in solar reflectors.

Check out 3d fingernail decals. Super thin. Designed to be clear varnished over. Also you can get a truckload for buttons.

I hammer the frets in the traditional way.  When I glue in the fretboard, I use plenty of clamps and a full length piece of hardwood top and bottom to spread the pressure and prevent clamp marks.  Make the top hardwood piece a little narrower that the  fretboard so you can see and feel that the fretboard is properly centered over the neck.  This method also insures that the frets are all properly seated.  I have been using Hide glue on the fretboard in case I ever have to remove it.

What I learnt from my friend Tyko Runesson, swedish-swiss luthier who builds beautiful guitars and other stringed instruments: shorten the distance from nut to first fret half a millimeter, so the first halftone will not be sharp. This for classic guitars with low action, for high action as preferred for playing with a slide try with a millimeter.

Moritz I saw that somewhere else as well but it was not clear - does it mean to make a normal fretboard spacing with the nut moved closer to the frets a half mm, or is only the first fret shortened and the rest normal as measured from the nut?

cut your fret slots normally, then cut for your nut a tad closer to compensate for the open string being the only note without the extra tension of being pressed to the fingerboard. 

a good article about compensation at the saddle and nut is:

although, trying to measure and cut a slot to 0.5mm or 0.012" accuracy is so tiny, I accept the error inherent in the process anyway.

Seems like a good idea.  Alternately, it seems like you could file a bit on the nut where it contacts the fretboard.  Don't file the upper part of the nut, just the lower part, so the nut overlaps the end of the fretboard..  If the results weren't satisfactory, simply change nuts.  Better than scrapping the fretboard.  Just sayin' .  I would like to hear other opinions on all this.  On my ukes, the first couple frets seem pretty sharp.  I keep lowering the action at the nut and it improves, but I don't know how far to go.

JL and Gary thanks for clarification: mark the positions of nut and frets as usual but put the nut for low action half a millimeter towards the first fret. The saw you are fretting with is about .6 millimeters so you get the idea.

Gary's idea of the nut protruding over the fretboard is a lot better than the alternative to glue a fine piece of wood or bone afterwards to correct a sharp first halftone...

Thanks all - for me sometimes it takes a few ways of explaining but now it makes sense!
