Needling a wall from just one side?

[diykat]

hi

I've got a diy book Collins Complete DIY Manual, p132) that shows how to needle a wall so that a lintel can be added and an opening made. I want to make a high opening in the chimney which is currently bricked up. Can needles be put in and supported from just one side?

thank you

hi, thanx for reply

what about metal wall supports? book says 'each support requires only one adjustable prop' - description is a little too brief though - can i use these, or if not, how do i go about supporting the chimney wall to install a lintel - i only want to heighten the opening - not demolish the whole thing.

thanx

you could use an acrow with a strongboy but personally i would say its beyond the DIY reaches (no disrespect inteneded) best to get a local builder round
