I am David Ward from Alveston and I manage the Society’s silver solder bank. The Society hold stocks of most solders and fluxes used for copper boiler making as well as citric acid for pickling and a small brazing hearth. There are also some meshes for making spark arrestors. We aim to provide these materials at competitive prices, even for small quantities.
You can contact me by phone (preferably) or e-mail (see membership list for details) and I will deliver to Begbrook or Ashton or you may arrange to collect from me at Alveston. NB this is a members only facility so I will need your membership number.
The EU have now banned the retail sale of silver solder containing cadmium from December 2011. We still own stocks of cadmium bearing alloys and members are advised to only use such grades in well ventilated situations, do not overheat the work and avoid breathing fumes.
