Hi all,
i'm building a guitar for a friend, i have fretted the fingerboard for scale length 25.5/648 mm, the bridge is a Schaller Floyd Rose tremolo, now i have to route the neck pocket in the body but i don't understand how to calculate it, if the scale length must be 648 mm i image that the distance from the lock nut and the bridge pivot must be 648 mm but if i try to calculate it here: http://www.stewmac.com/FretCalculator/ and i choose 24 frets and 648mm length
the caculator say that the distance must be: 633.706 mm (±0.5 mm) Why? in another words what i have to do when routing the neck pocket?
sorry for my english!!
