I plan to put a bracket up in my garage for a heavy punch bag. The wall that I want to use connects to my lounge - on the other side is my LCD. The wall is very solid (100 year old detached house). There is a chimney that runs up between the lounge and garage. Would I get any problems with the screen do you think? I have asked a relative and they are certain there wouldn't be a problem. On the garage side the wall juts out about a foot for about four foot wide of the wall. This is where the chimney must be housed. Either side of this is the other side of the lounge wall - it's solid as. So there must be a foot of solid wall until you get to the solid wall that is on the other side of my screen. Hope this makes sense? I used the opposite wall which is made of brick and I've just knocked the bag and bracket off the wall after about three right hooks!
