Greetings Everyone

Here is a technique I have used a few times.  It relies on the record
being flat (not warped) otherwise it makes things very difficult.

I place all the pieces on a hard flat surface (kitchen counter for
example) and bring the pieces together tightly and by hand.  I use
something heavy (a few large unopened tin cans for example) to hold
things together.  I have a hand held microscope to check that the first
outer groove is aligned correctly.  The adjustment part is what takes
time.  Once everything is in place, I use a needle dipped in
cyanoacrylate (crazy glue) so that it forms a small drop on the end.
By applying the needle to the outer end (on the edge of the record) of
the crack(s) the glue is sucked into the crack by capilarity.  It may
not reach throughout but it is usually sufficient to hold things
together well enough for one more play.

Use at your own discretion
