Attach birdhouse

[Anna Bo]

I was thinking of attaching a birdhouse for a white-throated dipper in a culvert in a similar way as the box in the picture. However, I don't know how to attach it to the metal pipe. I have considered using pop rivets or anchor screws, but can't find any that seem suitable. Therefore, I wonder if anyone here has a good idea on how to secure the birdhouse?

Can't it just be screwed on with suitable (sheet metal) screws?

Welcome!

Self-drilling sheet metal screw.

The question is whose drum it is and if they accept that it starts to rust where you make a hole in the galvanized layer on the sheet metal?

I had used foam...

Glue a wedge-shaped piece of wood with PL400. Once it has cured, screw the birdhouse onto the wood piece.

Thanks for all the suggestions! I don't need to stand and hold the board there for a long time if I choose foam sealant or PL400? I assume both work well in humid environments.

You can place a board across the culvert while it cures.

Go with PL600 which "grips immediately" so you should avoid support. However, how immediate immediate is, I dare not say, but if the advertisement isn't blatantly lying, immediate should be fairly immediate...

Neodymium magnets?

Of course, they work best if I'm right in seeing that it's sheet metal…

It is acrylic-based, not water-based as stated, for obvious reasons.

Ok, great. Thanks!! I don't have the ability to set up support there and I can't handle it for several hours I hope it can support the birdhouse. Mine, unlike the one in the photo, is built with pine.

Use PL600 that "grips directly" so you should avoid needing support. How directly direct it is, I can't say, but unless the advertisement is lying, direct should be reasonably direct...

Naturally works best if I'm right that it's sheet metal…

Maybe together with the glue?

 

[doubleH]

Use PL600 which "grabs immediately" so you should avoid the need for support. However, I can't say how immediate "immediate" is, but if the advertisement isn't completely lying, immediate should be reasonably immediate...

But PL 600 is intended for indoor use - explicitly not in wet rooms and a water culvert is a very wet room

That doesn't sound good at all. Now I'm a bit unsure. Maybe it's easier to just screw the housing in place anyway.

That didn't sound good at all. Now I'm a bit unsure. Maybe it's easiest to just screw in the birdhouse after all.

Easiest maybe, but not so good for the pipe as the hole will lack protection from galvanization. At work, it's important to properly rust-proof if we make a hole in a galvanized metal part.

Pl400 (or other construction adhesive for outdoor use) + a board that sits under a bit of tension for a day or so, to let it cure a bit, is preferred.
