After spending virtually the whole of my career soldering anything from wire as thick as your hair to 3 tonne mould cylinders in the security bank note industry I am taking a risk and putting myself up as something of an expert.
There are two main criteria required to make a good joint, cleanliness and a good heat source.
Both surfaces must be impeccably clean, degreased and back to bare metal.
The best method to supply heat for this particular repair is a good sized copper soldering iron heated by gas, say 3” x 1” x1”.
As suggested in a previous post Bakers No3 Soldering spirit is what I would also suggest.
H&S, toxic fumes will come from molten solder and from the soldering spirit, use in a well ventilated area and wear safety goggles and face mask. Also gloves as the spirit contains quite a nasty acid.
1. Having cleaned the appropriate surfaces apply some clean soldering spirit to the areas to be joined, I use a hard wood stick.
2. Tin (solder) the areas to be joined making sure that they are well covered on both the frame and the new cloth.
3. Lay the new wire cloth over the frame. Due to the 3D nature of the frame I always start by attaching the centre web joint. Hold the wire cloth down by using your hard wood stick and apply the heat, watch for the solder to flow. Remove the iron whilst holding the cloth down. Gradually solder your other joints working from the centre.
Tip. Solder the cloth in the areas to be drilled for the mounting bolts to around 1/2” this will allow easy drilling and not fraying.
Hope this helps. Good luck

I am always interested in any information about Rosengart details or current owners.
