Just a suggestion....as you've said to use less of the glue, I advise using a 
minimal amount of tape to hold broken pieces together (and obviously don't even 
think about this procedure on broken glass lacquers except on the ungrooved 
portion). Having grown up with 78s which parents occasionally had to glue 
together..back when the only option was LePages Iron Glue which you applied 
with a matchstick (remember, kiddies?), I'm used to positioning broken pieces 
together. But be aware that certain discs, such as Decca and Capitol, will have 
breaks that tend to flake on one side..too much tape and you remove more of the 
disc's surface along with the tape.

I would also definitely not use 2" packing tape, except for the lousy cheapo 
stuff sold by the stationery stores..the GOOD stuff is thick and tends to stick 
and may leave deposits or may actually break more of the disc when you remove 
it. Scotch Magic has been my choice since the early 60s and I find that discs I 
pieced together then (along the outer edge) are still intact today. It's also 
easy to remove.
