They're a pain. You have to slide them over the two legs from their
loose ends. Then you have probems if the "joint" is actually a
component of some sort, not just solder, and any bigger diameter than
the cables.

for splicing automotive cables.

Easy, as they're small diameter

Preferably adhesive lined.

* Two (or three) thin glue-lined heatshrinks over the legs

* Short ring of heatshrink over two of these.

* Shrink. Pull the two legs into neat D-shapes, so that they form a
solid oval section without gaps.

* Bigger piece of glue-lined over the third leg (with or without a
thin bit first, depending on diameter).

* Shrink the lot. Make sure there are no gaps around the two legs.


Otherwise do it as a "tripod" not a "Y", which is dead easy with glue-
lined.
