First gazebo project, frame wobble

Galvanised will work and grease the threads of the coach screws before you screw them in. You can also use stainless if you wish.

Silver zinc galvanised like this Adam?

For a more aesthetic solution to the base fixing, angle drill through the uprights and resin fix into the concrete base, I would be more worried about the bottom of the post rotting, should have a skirt of some kind.

Thanks Mike

There will be a gap all round between beams and roof so guessing that would reduce uplift considerably?

Think about how an aircraft wing works, a gap underneath could make uplift worse, especially without the posts fixed down, but those sort of weather conditions are rare in the UK on small structures.

I would use big welded feet to anchor it.
You can then cover these with oak offcuts to shed the water off them .

Like this but better if from fabrication firm.

I see. Going to fix them down. I hate flying!

Cheers

I agree, it's like a wobbly table or a racking workbench - the top can be stiff and stable, but the legs can still move

Yep, so going to fix the posts down first

Thanks

Thanks but would need to raise the frame to fit so will go for sonwthing heavy duty that can slide uo to the post faces

Thanks

Angle grind one side off the Bolt down square post support and slide it onto the post, but very ugly, still think the angle drilled stud solution may be the most aesthetically pleasing, counter board into the post and plugged, still needs a skirt and DPC though.
