[Carpentry] Is there a single stud or two studs in this area?

Click for full size
I'm trying to determine if there is only 1 stud or two studs in this gap between my two windows. I think there might be two studs like | | this, and so I don't want to drill directly into the middle if that were the case. But if there was only 1 stud, then I guess drilling in the middle would be safe.

Using a stud finder doesn't really help in such a small space, and I plan on mounting an articulating mount that mounts to 1 stud with 3 lag bolts vertically. So should I drill in the middle or drill a little to the side?

there would have to be 2, one for each window to attach to.

One trick that has worked for me on sheetrock is to probe the area with a needle in an inconspicuous area. (A paper clip would also work). Press it firmly & directly with a little twisting into the area in question. If it pushes through past 5/8" you are in open wall. If it stops on something solid, you probably are on a stud.

When you are done there is a small blemish on the wall but typically this can be filled with a dab of something. The key is to choose a spot low on the wall that is not too noticeable but high enough to be past any sill plates. Directly on top of moldings is usually a good spot.

In this case there would be a 2x4 at each window edge and depending on how the header was supported, there may be double 2x4 supporting each end of the header so you could have up to 4- 2x4s in that area. Since you only have 5", there are probably 3 there.

There should be 3 studs here. A "king" stud in the middle,and 2 jack" studs on the outside. The outside "jack" studs will be supporting a header for the windows with a 1 1/2 thick bearing for header. The center or "king" stud is called that, as it goes from the bottom shoe or plate continuously to the top plate in the wall. A jack stud is not continuos as it is cut to support a header for a door or window, and a bottom support for a window. You would be best to try drilling your mounting holes in the center.

You sure? It looks too thin to me for 3x 2x4's plus drywall.

It's probably nothing but wood in that space.

Yes, 2 2x4's in the center = 3"
Two window jambs at 3/4 = 1.5
Total 4.5"

I'm confused about how you worded your response. You're saying I'm right and it's too narrow to have 3 2x4's? 1.5+1.5+1.5=4.5" plus one layer of 3/8" drywall on each side is 5.25" Also, I do not see a jamb in that pic and am assuming it's like my current apartment and it's just an outside corner on the wall (just drywall wrapped with a corner bead and the window is recessed).

Hm, that sounds bad.. what happens if it is "all wood". Or is that a good thing?

Well when I run my stud finder under the windows where its like solid, in that area between the two windows, the stud finder buzzes about 2-3 times... But is the area under the divider the same as the divider itself?

And is it safe to drill into the side ones? or the middle ones. I guess I will try the paperclip trick that mackey suggested, and report back.

thanks everyone for your responses.

There could also be a continuous header spanning both windows with queen studs for each window. It would be structurally better this way, but figure solid wood between openings ...

Okay, I used a paperclip to probe around, and pushing in, it does stop at 5/8" but, that doesn't really answer how many studs are in there. Should I poke more holes to see if theres any gaps?

I also read that it might be better to drill the pilot hole at an angle, like for example, angled either towards the center or angled inwards as opposed to drilling straight, so that the bolt can catch more of the wood? Is that something worth doing?

Drill straight. Looks a lot better and difference in strength is not that much.

If you poked in the center and hit wood, then there are 3 studs in that space and they are close together. See the math that shdesign did above.

What is the bolt pattern you need to mount this thing to the wall?

I think there are two studs, side by side, and drilling into the very center will likely be a weak attachment because you'll be drilling in between them.

The only way to really tell would be to open up a small bit and look. If you see plain wood, drill there. If you see the groove between two pieces, drill somewhere else. Patch the spot you had to open to check.

a small long bit every 1/2" will tell the story.

No big deal then just patch and maybe paint.

And you almost can't have too much wood.

It really doesn't matter.

Just drill and find the wood.

He did that with a paper clip and found wood.

I think there are two studs with 1/2" plywood or similar between them. Add a 1/2" of Sheetrock on each side and that fits with the measurement.

Update:

My lag bolt, snapped and broke off and is now stuck in the wall... FML. I couldn't drill very deep for the pilot hole. My drill would just get stuck maybe 2"s in, so I just thought that would be enough but I guess not.

UGH

That happens when the pilot hole is not as deep as the lag bolt is long. Perhaps your lag bolt was too long. You don't need over 2" IMO.

Could be too small size of a pilot hole as well. Too much torque and snap.

Well now we know for sure the wall is solid there.

Is there enough exposed that you can back it out with a small pipe wrench or pliers if you have a VERY strong grip?

If not, try cutting it off even with the wall and mounting the plate a little above the broken bolt.

This time when you drill the pilot hole, make sure it is's diameter is large enough to remove wood almost to the root of the threads on the lag bolt. Leaving excess wood in place does not add to the pull out strength but does make lagging a tricky affair, as you found out. Also, depending on what you are hanging, you may not need to go much past 2.5" or so. A little bar soap on the threads also helps thread into wood.

When you turn the new bolt, if you take your time, you should be able to feel when the bolt is under stress and getting ready to snap.

You do realize that a hole in the center of the broken off lag bolt has to be drilled in sufficient size to use the smallest of the extractors in your post? Good luck

I guess you have learned not to drive a cheap ass Chinese 3/8" bolt into a 1/8 pilot hole?

If it was me I would just slightly re-orient the whole project up down right or left a little and drill a bigger hole and buy a few bolts.

But that's me.

Depends where on the threads the stud broke and how ugly the broken stud is sticking out of the wall. If it snapped off flush, good to go; if 2" is sticking out,,,,?
