I was doing a proper repair on a damaged leaded panel which had been bodged up many years ago: as I have both the equipment and the soldering skills to do a proper job. The panel originally dates from around 1935, and fits into a metal casement window, itself set into a wooden window frame
So I carefully removed the putty and took out the panel, laid it flat and started to cut away the damaged lead cames…..
…..and I discovered that the horizontally running lead cames were actually steel cored in the centre so it took quite a bit of careful work to cut through these at a junction, before I could solder up a new lead section/replace the glass etc.
The steel cores to the lead meant that the entire lead panel was very strong in one direction and could be easily handled by the edges with no risk of it bending – while the usual amount of care had to be taken other direction.
I did try and bend by hand one of the discarded 4inch or so long steel cored sections - and it was basically unbendable by hand force only
I’ve heard of tall/thin leaded panels being wired up to bars set into the window structure to prevent them bowing but I’ve never heard/seen of strengthening being actually built into the lead itself. In this case anyway the strengthening was in the horizontal direction not vertical.
Obviously the centre of these leads were much thicker than the normal leads in the rest of the window to accommodate the steel core, though the overall width of the lead came itself was still 0.5 inch; the recess where the glass fits being shallower to compensate for the thicker centre.
Anyone else seen this?
