How long for a neck to "set in"?

[kesslari]

My recent purchase (used Tobias) arrived with a pretty significant bow in the neck. Based on my reading, I was conservative in correcting (1/4 to 1/2 turn of the truss rod screws per day over 3 or 4 days) and got the neck and action quite nicely set. It plays beautifully, but is continuing to move a bit.
I think i last adjusted it a week ago. It has definitely changed a bit since then, and is decidedly straighter than I left it when I last adjusted it (with a consequent bit of buzziness on the low B string).
I'm hesitant to continue adjusting it, I'd like to let it settle in before doing anything else to it.
How long should I let it settle?
Also the weather here (coastal CA) is very wet right now, with only moderate temperature swings. How much is that affecting the issue?

Any suggestions from competent setup people would be very, very welcome...
Thanks.

Necks really never set-in, they always move, but trussrods adjustements usually don't take a lot of time to "show up": many basses will have almost instantaneous reaction to adjusting the trussrod. Since you waited 24 hours between each adjustment and you noticed that the neck is still moving after a week, I'd wager that it had time to set and that it is now reacting to wet/humid conditions you're now experiencing.

Check for back-bow, but I'd wager that the neck is now dead-straight and all you need is a little saddle lift to make it buzz-free and very playable.

usually takes a day for my stuff. Most of mine are bolt-ons. The humidity affects mine more than temp. I like to set the truss to straighten the neck as flat as I can get it(One time with a little back bow) with the strings off , against my straightedge. After that I check for angle to body, shim if necessary(bolt-on), set up as usual, play it a while and look at it some more the next day. Usually I get them dialed in nicely the second day. I've had very few problems thus far with this habit. Take yer time and try to enjoy the working on it. It'll pay off, trust me on that. Even if you decide to defer to a pro, you'll at least know something more than you did.

Thanks. It's a double truss rod, so I need to make sure that I've got both sides equal (not positive right now, will check tomorrow). It looks to me like I have about the perfect amount of bow in the treble side, and that the bass side is virtually straight.
I may loosen the bass side just a hair.
If I was convinced that both sides were equal I'd just raise the low B a touch at the saddle.

Even if you decide to defer to a pro, you'll at least know something more than you did.

Thanks for that - helps combat my inner "what the heck do I think I'm doing trying to adjust this?" voice. She's clearly playing much, much better, really well in fact.
I just know she can be really close to perfect, and I want to get her there.
