im making my first neck for a bass guitar and want to know how long the truss rod should be. I want a 36" scale length on it and im not sure how long the truss rod needs to be

Wouldn't a 24" truss rod work on both 34" and 36" scale basses? I remember reading that for the longer scale, it's always prudent to reinforce with carbon fiber rods. Those are available from StewMac and various online stores.

Check with the folks at TalkBass or PM Ormsby.
