Hi Guys,
Need a bit of reassurance / advice
A mate has asked me to fabricate a couple of 'drop in posts' that will go in his garden to support one corner of sun shade. The other 2 attachments will be on the side of his house.
(i'm making 2 as he wants 2 shades in two different locations)
The plan is to drop a 1m section of 60x60x5 box into a concreted hole that sits behind a gabion in his garden. This is going to be bombproof and i'm not worried about that...
The 'post' is going to be 2.5m in length and 50cm of this will be in the 'ground support' leaving 2m above ground. The post is going to be 50x50x5 box to slip in (with a bit of refining) to the 60x60. I will be welding a 'collar' or 60x60 0.5m up the post to act as a stop. Fixing an eye bolt at around 1.9m from the floor to support the one corner of the shade that is a trianguar cotton sheet. He wants to be able to take it down in winter so it shouldn't bear weight of snow or be subjected to major weather. It will have a slope too to shed the rain...
I'm hoping this should be over engineered, and pretty solid for the given task?
This brings me in to the main point... he then wants to be able to fix an eyelet at about 1.5 - 1.8m from the floor to attach one end of a hammock... the other end to be fixed at a currently unknown location that will be decided later.
My question is...
With the 60x60x5 ground fixing and the 2.5m (2m above ground) 50x50x5 post, will the post 'flex' too much. ultimately I don't know where the final hammock post will be going and I need to treat this fixing as a stand alone, un-braced support. We really don't want it to load the sail and the house when the hammock is up should the forces be applied in that direction!
Will a 5mm wall be stiff enough?
For clarity, the 60x60 in the ground is 1m long as the garden is on 2 levels/ the gabion is full of stone and is 0.5m high so we wanted to go down behing it by another 0.5m to reduce the 'lever' effect from just tipping the gabion over!
Any reassurance / advice is gratefully appreciated...
