soldering a silver plated sax

5083 Views 11 Replies 6 Participants Last post by  Chu-Jerry
I have done solder repair on lacquered saxes so I have a pretty good idea what the results will be. Now I have an old silver plated sax where I am thinking of removing some posts (instead of cutting off the keys). Searching the forum I am not sure if silver plated horns are easier/cleaner to solder than lacquered horns. What do you think? Thanks.

I find that the "stay brite" solder works best on silver instruments. It comes with its own flux. I just cut a small amount solder and place it on the join add some more flux and heat up - allways lees to remove afterwards and if you havent used enough solder then just cut another piece. IMHO a far better method than to heat and then apply the solder and possibly be left with excess solder to clean off.

Would you have the post held in place and have the solder run in by capillary action or would you get the solder onto the parts first?
Usually you run the rod through the post and screw it in to the matching post. This lines everything up. Then you solder. Same with pivot screws (at least for me).
I use the rod or the key if the post holds only a pivot screw and hold the parts in place using wire.

I use the capillary action rather than the "tinning method".

good luck and keep us posted
Jerry makes a good point re the flux. The flux that is supplied with the stay brite solder I prefer to use comes in an "eye drop" type dispenser which is ideal for applying small amounts.
