Mounting a Punching Bag

reingam@hotmail.com

Hi all. I am thinking about mounting a 60lb/30kg puhching bag to the exterior wall of my house. The bag will be hung from a chain and mounting using a bracket with with 4 holes. The wall is solid masonary with a rendered finish. What I planned on doing was drilling a 80mm hole into the wall and then fixing the bag/bracket using M6x80 rawlbolts/dynabolt. I was then going to fill the reaming gaps with caulk (hoping that this would act as some sort of a shock adsorber). Could anyone advise if this would work. What I am afraid of is that the stress from punching the bag could crack the render on the wall - will sinking the bolt deep into the wall prevent this? The render is 25mm thick. Thanks in advance for any tips/suggestions

Is there any other stucture that you mount it to?

No it's just the punch bag attached to the bracket by a chain. The bracket is designed to be wall mounted so it won't be attached to any other structures.

There's a wooden lattice fence adjoining to one of the walls - would I better trying to fix to this? I could potentially fix to one of the support posts but again this is nailed into the render so I don't want to put too much strain on the support post in case it gets pullled from the wall.

Here's a previous thread on mounting punching bags. Maybe there will be some information that can help you:

Hi thanks for the responses.
The posted thread had some interesting pointers but it's skind of different to my situation. I'd read the posted thread thread previous to making this post - I hate posters who haven't read all the previous information. My main concern is with regards to the render. I've decided that I'm gonna use 60mm bolts (100mm seemed a bit too long) and mount it too the wall. Do you think that this will cause the render to crack or will it hold?
