Well having read it all so far....
I use 24hr araldite epoxy ( structural adhesive). This stays fluid for about 2 hours working time and I do a batch of tubes. I do scuff up the tubes with sand paper first then wipe with Cellulose thinners on tissue, get grease off and smells nice ( am I allowed to say that with HSE?). I use Blu tac to bung the tubes before inserting ( not sure what's that's called over the pond). You can then push out set epoxy and use a counter bore to square up the ends. I leave to set in a warm place overnight and clean up next day. I like the way the epoxy fills any slight gaps . Also having once taken a split blank apart with heat The epoxy gave a really good even coating. I should mention always revolve when inserting to get a good spread and remove air. I also use a Mcdonalds coffee stirrer (other brands are available also free!) to apply glue into the blank and let it soak in for a minute or so before inserting the tubes ( hence need to plug tube ends or it takes ages to clean up!). Dental probes are great for removing chunks of hard epoxy in the blank ( if that's a issue anytime )
Have tried CA but once had a tube stick to the blank, then to me! Lots of cursing +acetone and a rethink later moved to epoxy.
For Lignum Vitea I swab the hole with cellulose first as, ( even though the wood was 50years old from a bowling ball) it was full of oil and a challenge to drill. Only time I have ever had to ream the hole with a larger drill to get the tube to slide in ! No finish needed as it burnishes up to semi gloss with a cotton rag after sanding through the grades.
Bit early but Happy New Year one and all !
