Hello all

I am unable to find old 50/50% tin lead wire, but I have found and bought the following:

SN 30% Pb 70%, I suppose SN is tin, and of course PB is lead

and SN 97% , 3% Cu, Cu is for copper

I have read people using 2% silver, which I find extremely difficult for the ribs as the temps must be very high

Can someone tell me if any of the above solders I have found are suitable??

I also have strong acid flux for the tinning (residues will be cleaned after very well), and rosin flux for the final soldering of the ribs on the barrels

Hope someone can help me as I plan to do the job in Easter holidays
