The
medium of lead came lends itself to long flowing lines,
and these flowing lines present very acute angles for
the worker to joint, which are almost always a difficulty.
When
a joint is too acute for lead dykes/nippers or a knife
to cut accurately, overlapping the joint is necessary
for neatness.
Use
the lead dykes to cut out the heart of the lead back
to the point where the meeting leads overlap. After
cutting, the upper and lower leaves of the came are
bent back at various points. Use a fid, oyster knife
or other tool to flatten the leaf and smooth the remainder
of the heart on both the upper and lower leaves.
Position
the came without the heart so the lower leaf is under
the came it meets, and the upper leaf is over it. You
can trim the leaf to butt the meeting came now or just
before soldering. To trim the leaves, first align the
leaf to provide a smooth line. Mark a scratch with a
nail or lead knife to give a guide for cutting with
lead dykes. Smooth the leaf down, flux and solder.
The
other side will be done just as the first, once the
panel has been soldered on the first side and turned
over.
On
long joints it is not necessary to do more than sweat-solder
the joint.
