Slight neck dive on my Modern neck

[rainfall]

I built my first full Warmoth strat guitar not too long ago and absolutely love it. Except for one thing: The neck x body balance. The guitar doesn't neck dive like a Gibson SG, but if I'm playing sitting, and just let the guitar rest on my body/legs, it slowly dives. I kind of feel the dive while I'm playing, which is a bit annoying.

Is that because I have a Modern construction strat neck which has double expanding truss rod? I ask this because I might buy another Warmoth neck, and this could change my decision of construction of the next neck.
EDIT: I did not weigh the body or neck, but the body isn't all that light. I believe the guitar weighs about 8 pounds overall, which is on the heavier side for an HH strat rear mount.

Here are the specs of the body and neck of this build:

Body
Material: Alder
Route: HH rear route
Jack: Side
Bridge: Fender hardtail

Neck
Material: Roasted maple with Ebony
Construction: Modern
Tuner: hipshot locking with adapter plate

Thanks

Who can tell just from the description given. I have some modern necks that do not do what you describe.

How light is the body for example?

Did you put the light plastic tuning buttons?  Do you wear a strap? Generally the geometry of a strat shouldn’t neck dive.  I’m wonder how your sitting,  do you use a pedestal for your right foot?  I think you need a pal to come over to your house to seee what your doing.

The neck dive is very slight when I'm sitting. This doesn't happen with any of my other guitars

The tuning key is this one (maybe the metal adaptor is weighing too much?)

No my friend, tuning buttons, you can remove the metal ones and replace with plastic, maybe save three ounces. Because the tuners are at the end of the neck what Archimedes said about leverage applies.  But seriously do you use a strap? How are you sitting?  On a stool with your right foot up on a platform?  Did you talk to someone, maybe a teacher, local luthier, fellow musician?

Sometimes a person you actually know can give better advice than an anonymous person on the internet.

If you see how I’m sitting in my avatar without a strap I wouldn’t expect the neck not to dive slightly.

I know exactly what you're talking about. I experience the same thing with a few of my modern construction necks, but not all. However, I've weighed my necks and in general, my modern construction necks are heavier than my vintage modern by a few ounces. Depending on the weight of the body those few ounces can make a difference.

If it bugs you I suggest you follow Rick's advice and consider swapping out tuner heads. If it really bothers you could also consider replacing the UMP plates and use the provided screws...if they're actually lighter. If it really really bothers you consider adding a high mass bridge or putting a bit of lead tape in a body cavity.
