Thread: Hanging Project on Wall

This is an odd wood related question...

I've picked up a large mirror from a disposal measuring about 1.5m x 1.5m and weighing in at about 20kg. The majority of the construction is wood (ply it seems) with (obviously) a mirror front.

What's got me miffed is how to mount it...

On the back it has two 1/4" threaded studs 700mm apart. I would say there is a spreader plate / boltheads burried deep inside the timber back. The original mounting (unsafe!) was simply two short lengths of chain (over the stud with washers and nuts) ending two split rings (not kidding) which were hooked over screws in the wall.

There has got to be a better / safer way. Adding anything to the ply is out of the question as its quite thin and I don't want to risk damaging the mirrored front by trying to tap in to the timber - looks like using the existing studs is the way to go.

The only "clever" idea I came up with was this (sorry, it was metal not wood this time):

* Get a 1m length of rectangle cross section steel tube about 15mm x 40mm
* Cut two vertical slots in the long face 700mm apart and about 1/4" wide
* Drill a large hole (or make slots) at the top of each slot on the adjoining short face
* Add two (or three) mounting holes for the wall

After testing for fit one simply puts washer and nuts on the stud leaving them about 2mm undone, mount the bar to the wall then lift the mirror and drop in the slots.

Anyone come up with and other ideas?

Cheers!
