How do you get a cerve on the fingerboard?


If you're refering to the radius of the fingerboard (the arch from the E side to the G side), there are a few ways to do it. The easiest (well, least complicated...it takes some effort) would be a radius sanding block (http://www.stewmac.com/shop/Fretting_supplies/Leveling/Fretboard_Radius-sanding_Blocks.html), which you would attach sand paper to and would sand down the length of the fingerboard surface until the desired curve is achieved.
