Low Temperature Aluminium Welding Rods - bit off topic
Has anyone tried these to repair aluminium casing etc...
I made a right mess of a putting an insert into a aluminium cylinder head and wondered if I could start again by plugging the hole completely, re-drilling and tapping.

Just be warned that if it dosen't work you've made a whole load of extra work for the welder that will have to weld it again afterwards, even silicon rods can spatter badly if you try to weld over Lumiweld or similar, usually you'd have to drill it all out or grind it all out.

I tried to repair a Commando ally head with these. I couldnt get the area hot enough even though I insulated it. I think the process is more suitable to small parts

Frost sell stuff called Cold Front, its a sort of putty you build a wall round where you want to weld braze or solder, it contains the heat to stop it spreading and dissipating.
Don't ask me how it works but it does.
