Assembling
Pieces
made of more than one layer are either rivetted together with minute wire rivets
that are often countersunk and sanded flush to render them invisible, or soldered
together with a high temperature torch. Soldered pieces then require an acid bath
to remove heat-created oxides, and then a neutralizing bath before washing and
drying. These pieces then receive a light surface sanding before texturing and
surface marking. |
