Fixing a TV arm to a lathe-and-plaster wall

What's between the laths and the stone wall behind - just fresh air - or is there any studding. Ideally, you should screw the bracket to a substantial vertical stud. [With that weight potentially cantilevered

Assuming there aren't any suitably located studs, what you suggest should work, but you'll need a hole substantially wider than the bracket fixings in order to drill the stonework for fixing the wooden plate. A single thick piece of wood would be preferable to two pieces fixed together. Fix it to the stonework with rawlbolts - with their heads recessed into the wooden block, and covered with plugs. That way, you should be able to create a solid flat surface in the same plane as the plaster which, when the gaps are filled and painted, won't show - even though it's not completely covered by the bracket.

Is it articulated enough for the mount to be positioned on a stud and still allow the telly to be in the right place?

ITYF it's "lath and plaster". A lathe is a turning tool.

HTH -

I wanted to fix my swivel arm very close to the edge of a brick chimney breast. So fixed it with nuts and bolts to two lengths of steel strip - about 1/8th x 1" - and fixed that to the wall after chasing out.

You could do the same between two joists - less chasing than for wood capable of taking the load.

Can you locate the studs without damaging the L+P wall?? You might get lucky and find that there is a stud exactly where you want your bracket.

It made me think a bit about attaching an arm to a lathe. Thrashing about as it goes round and round.

I know it's only a typo, but it raised a smile.

There are studs, I think - 150 year old ones. I have no idea how securely they are fixed to the wall. Nor do I know whether there's a suitable placed one.

sterwhich, when the gaps are filled and painted, won't show - even

wall is - this is one of the worries with drilling and fixing, so I'll definitely consider this approach.

OK, will definitely consider this approach too - not sure how sound the studs would be - they're the original 150(ish) year old ones.

Indeed...

I presume you mean lath and plaster. A lathe is something that goes round in order to turn things to shape.

I was going to recommend the right drill bit to go into all that steel, too.
