I just wrap the ends. You can dip or paint on glue. Two coats is good ( I water down the wood glue, I used the end bits of a few different types of wood glue tb3, armor coat etc) .
A year minimum for drying. I've ruined a few staves by being impatient. You might need to ruin a few for yourself before you can truly appreciate the disappointment. Write the date of harvest on the stave.
If you have a small scrap peice of OS., debark it and watch it rip itself apart...
