Once the fretboard was placed on, it slid right into place because the nails helped align it.
Then I scrambled for every clamp I ever owned - only 7 in total. Clamps are expensive so I'll have to collect them slowly.
I managed to get even glue squeeze out. This means my joint was well prepared and I was very pleased. It was extremely satisfying seeing the glue squeeze out as I clamped it down. I also wiped off the excess with wet paper towels to help more glue to be squeezed out.
That's it for today. I'm leaving all the clamps on for 24 hours.
