epi project neck has been off for a while and has developed a "hump"

[poomwah]

I got a GREAT deal on a "used" t-bird neck (thanks Mark)  he pulled it off a new epi bird and the neck sat, and developed a slight bow.  The plan is to bolt the neck up, put normal string tension on it, give it some time, then adjust the truss rod and see if it comes out of it.  We expect it will. 
  How long should I wait before making a truss rod adjustment?

well, I got the body ready and cut out the neck pocket.  it was a set neck with a bad neck, so I cut the neck off even with the heel, added a 1/4 inch x 5 inch strip of mahogany down the center of the front and back to thicken the body up, it was SUPER skinny, then routed out for the t-bird neck.  Bolted it up today, didn't quite like the angle so I had to shim it up a little, but its bolted up, and the strings are tightened
we'll see if the neck straightens out :]

Your plan is reasonable.  Many times, something like this will work.  Let us know how it turns out.

[poomwah]

anyone know how long I should wait before adjusting the truss rod?

[drbassman]

There's no magic formula.  It should be several days minimally.

I'd wait no more than a week.

[poomwah]

I would say a time at least equal to the time it took for it to hump up on you.  There's no magic formula.  It should be several days minimally.

I think the neck sat close to a year before he sent it to me :[

[poomwah]

well, the neck is looking great... I waited a bit, then gave it a little bit of a turn, then waited till the next day, etc etc... and its got a GREAT action now.  the hump is gone and it has a nice even relief :]   

[Dave W]

Good. Glad it worked out for you. If you keep it attached and under tension, you should be in the clear.

[drbassman]

Good news. Hope it stays that way. Dave's right about keeping it under tension. It's better that way for sure.
