we started metalwork this morning in the Fas workshops. we got started by getting to know different tools and we were shown how to salder two pieces of metal together.
we cut off two pieces of a copper pipe. we made one end of the copper pipe expand so the other end would fit in. we put flax on it to hold it together and put it in a vice. i used a blow torch to heat it and leave it cool. i repeated this a number of times for practice.
we also silver saldered which is the same just using silver salder and you don't need flax. the copper turns red hot and you have to leave it cool as before.
