one of my students dropped my FrankenPaul on its head and the fretboard has come loose
I'm presuming titebond but want to check there isn't a fretboard specific glue

more clamps than tou might imagine.
Consider a small nail in each end of the neck, cut off and sharpened.  Press the fingerboard onto these pins to prevent it board sliding with the clamps.

it hasnt come off completely, just lifted a little bit at the nut end,

I only noticed it cos i was trying to find the source of the slight buzz.

was planning on just pulling the crack open and syringing in some diluted titebond. 

I have loads of clamps but not shaped, I can lay my hands on 3 or 4 capos, would they be preferable? or not enough squeeze?

You can make neck support blocks out of a scrap 2x4.  I've also had luck just using clamps with a plastic end protector rather than having a curved block for the clamp.

    Try and clean the old glue off, difficult without pulling the fingerboard off. Get a Exacto knife or other thin blade in there and do the best you can, no need to go  nuts. Also use some kind of pad with the blocks and clamps, I use folded pieces of leather. Just get as much Tite Bond in there as you can,  clamp it up , clean up the excess,  leave clamped for 24 hours and your good as new.

I have no luthiers experience, but I once managed to get some glue out in a similar situation where I had trouble with getting a scraper between board and neck. I slightly heated the neck area, then the fingerboard. Then I slid a piece of sanding paper in the crack, and 'pulled' out glue that way.  This was a cheap instrument, and I went at it without fear when heating. So I got out a lot of glue and it turned out nice.

In retrospect, I think it might be risky, as you can heat too much and just loosen more of the fingerboard.

If it is just a crack and not loaded with crud try squeezing it closed dry to see if it will even close.  I would not dilute tightbond but rather wick a drop of CA.

   aaargh was gonna attempt it this weekend, now i don't know which to use titebond or CA?

its a real hairline lift, you have to really look to see the crack, its only evident as a slight buzz when strummed  which goes away if the board is pushed down

Either will work. if it's that tiny a crack, I'd suggest using a fine-tip syringe to inject the adhesive regardless of which you use.  Titebond gives you working time - superglue doesn't give you more than a few seconds to clamp it.  But I have used it to secure a Casady fingerboard which sounds similar, and it worked fine.

  Franklin's Tire bond gets my vote. If you don't have a syringe gently open up the crack and pump the glue in with your finger tip using a circular motion then clamp for 24 hours. Don't forget to wipe the excess off with a damp rag before it dries. Good luck!

titebond worked ok

odd thing, it either shrunk the fretboard or swelled the neck, as now the neck is about a quarter of a Mil proud of the board both sides, no biggy for a beaten up old workhorse like this but would be a pain if it was on a restoration project

Almost sounds as if it were a lot more loose that it seemed.

It's the neck swelling, not the fretboard shrinking. Titebond is water based. Swelling is possible depending on several factors.
