In addition to all the many great build threads here on TB LC... (some being more detailed than others) ...
Go to YouTube & search "how to build a bass guitar" and/or other variations of that type search phrase... You will find quite a few fairly in depth tutorials. While they might not tell you every move to make... You will get a general idea of the process. Then after watching, studying, & re-watching ALL you can get your hands on... You can start filling in the gaps (things that some builders leave out of their tutorials).
I personally studied obsessively for about 6-8 months before attempting my first bass... And I'm a professional woodworker.
You didn't mention how much actual woodworking experience you have, or what tools or shop you have access to...
It is pretty important to have a general knowledge and familiarity with wood and woodworking machinery. If you are not that experienced, you might consider building something else first...
IDK...maybe a breadbox or a coffee table... something .... And I would also suggest that when you do actually attempt a bass build...you might want to make a "prototype" from a less expensive species of wood, before you cut up a bunch of pricey exotics.
There is also the option of acquiring some of the more difficult components pre-fabricated. For instance, Carvin sells neck-through bass necks, several options to choose & you would just make your own body wings to glue on... etc.....

Or you could just buy a complete kit... But in my opinion, that takes all the fun out of it!

Good luck!
