Making the Splice, Having the tube and repair section beveled
and buffed, the ends to be joined should be coated with one heavy
or two light coats of acid-cure splicing cement. With the tube and

on which is the patch B, turned back from the end of the mandrel
about the right distance, say 3 to 3) inches. On the male mandrel C
the tube D has been turned back about 7 to 7i inches, then turned
back again on itself about 3 to 3J inches.
Just as soon as the cement has dried thoroughly on the tube, apply
a coat of acid to the patch and
immediately place the two
mandrel ends together and
snap, blow, or push the end of
the patch over on to the end
of the tube. This frees the
female mandrel, which can
be laid adde. Immediately
wind the patched portion
(^till on the male mandrel)
with strips of muslin or inner
tubing. In 15 to 20 minutes
the cement will have formed
a permanent union, the wrap-
pings can be removed, and
the tube withdrawn through
the slot in the mandrel.
This done successfully,
the whole operation is re-
peated for the other splice.
If the splice does not cure
together well, it indicates
either that the acid supply is
poor or else the splicing was
