Fifty one view and no one has a comment, or offered to turn me some up.
Hi all you turners, I am looking to raise my settees by 150mm, I think Bun feet would look the most appropriate in a fairly heavy wide section, what would you recommend?
Plus if you think about it, the threaded rod is just a locator, the weight/pressure from the sofa is directly transfered to the wooden foot.M8 should be good to about 6 kN which I would think is adequate for a sofa leg. I would be more worried about the leg itself or the attachment point failing.
You are so right Derek. We still don’t have the whole picture. As an ex structural engineer. You are asking us to design a part to go on the end of a bridge structure without showing us the bridge!Rather than posting photos of the existing feet, please post a photo of the entire settee. The point is that the feet are part of the WHOLE design, and not simply a tiny area that is tucked away and separate. The existing feet are squared, and this design may suit the settee better than buns, or vice versa. We cannot advise until you allow us to see what you see.
Regards from Perth

Except that when lifting the sofa back up it's a bending moment on the 8mm rod and its the sheer strength that is in question.Plus if you think about it, the threaded rod is just a locator, the weight/pressure from the sofa is directly transfered to the wooden foot.
I am just calculating the UDL, wind loading and end bearing requirements, oh and not forgetting the thrust measurements.You are so right Derek. We still don’t have the whole picture.

Well that worry about bending the rod is about 1 second of the buns life. If they bend , bend them back and then they should be good forever.Except that when lifting the sofa back up it's a bending moment on the 8mm rod and its the sheer strength that is in question.
