What type of bridge are you looking to make? Fixed, utilibridge, whoopie, etc. Figure out your preferred bridge length or make an adjustable one then account for your buries. I do a full length bury with locked brummels on a fixed bridge just because I don't like the "bump" from the cut ends when rotating. A utilibridge eliminates the bump and is fully adjustable but slightly more technical to make. The whoopie bridge allows adjustment but may have the bump again depending on length of bridge.
