As a hobby within a hobby I like to restore old balsa and wooden planes that are destined for landfill. As most are either badly crashed/splintered or full of wood rot and plans are not available it is a little time consuming. It does tend to be frustrating but very rewarding to see the old bird start a new life.
I use a range of glues but 3 are most important. Epoxy, CA, and a Por-UHU Equivalent, (a craft glue which is available in the US as Sullivans craft glue).

The Epoxy is for hardwood/metal/CF/Ply.plastic joints including the re-laminating of swollen or damaged plywood parts.
The CA is used to piece together splintered balsa parts for use as templates as well as a rapid locking method when fixing the alignment of wing ribs in a jig.
The Sullivans is used for sheeting work and blind, (fill and bind), repairs.
An accidental and rather fortunate use of the Sullivans is that it also glues FB extremely well and provides a superior final product than Hotmelt on FB planes though it takes a while longer to set/dry.
Just what works for me!
Have fun!
