House sign repair

<p style=”text-align: left;”>Quick question that someone is bound to know the answer to. Moved house a few months back and the sign is missing a letter so I’m in the process of making one. Question is how to attach it? I was thinking of once the signs stripped of paint and cleaned up I could key the sign and letter and araldite it or I think I’ve some silver solder somewhere and my dad’s old soldering iron which is big enough to burn holes into the forth rail bridge.</p>

<p style=”text-align: left;”>Any suggestions much appreciated</p>

Is that cast iron? If so, your soldering iron will be no good for that, it’d need proper heat, possibly a blow lamp, more likely oxygen-acetylene for silver solder, as the cast iron will take an age to get hot enough, then you have the problem of it cracking as it heats up.

Araldite every time.

If you do use an epoxy, it’s best to use one intended for metals rather than a generic one. If you can I would also drill a number of small blind holes on each side- they only need to be 1 mm deep or so- and make sure the epoxy fills them as this will provide a better key.

We need to know what the sign and the new letter are made of first ;o)

if both peices are metal then silver solder will work but you’ll need a MAP gas blowtorch rather than a soldering iron to get the metal hot enough. Both peices need to be really clean and you need to get the metal glowing cherry red.

I’ve used this kit of solder rods and flux for various metal jobs where welding hasn’t been an option – such as joining different metals together

Any chance you could drill into it from the back and use a couple of screws to fasten it? (Plus glue probably).

Thanks for the replies, the sign I think is cast and I’ve made the letter out of mild steel although I’ve now found out while cleaning it up that the rest of the letters are wooden and have been glued on.

I did consider drilling and tapping it and then filing it flush but might go with some sort of epoxy

Epoxy may struggle with thermal expansion so something with a bit of flexibility might be better

Magnets on the back of each letter. Much opportunity for Fawlty Towers fun…

Think of a sob story & get it to the Repair Shop?

Gas axe will sort that.

After a fashion.

CT1 adhesive works well binding wood and metal, and it retains flexibility and resistance to shrinking, uv degradation and cracking

Chemfix will fix it. Although I have found soudal fix all to be very good. Just abraid the surface with some 80 grit and clamp it together overnight
