I was working on some pens today and while truing up the end of a blank, my pen mill caught an edge and ripped a huge chunk out of the blank. Now I am very careful when I glue so I don't think it was due to poor coverage (incidently I use thick CA and sand my tube with 150 grit). It looks like the glue had not adhered well to the wood. Now I have heard of people wiping a piece of wood down with DNA to improve the adhesion of glue, but how do you do that inside a hole?

Any suggestion? What do you do to make sure you have good adhesion?

What species of wood was it?

Joel on oily wood I take a piece of stiff wire. I turn the end of the wire in a loop then put the small piece of t-shirt in the loop. I dip it either in mineral spirits, acetone or DNA. I run it in and out before I glue. Sometimes rather than CA I will use epoxy.

unless you can dip the piece in one of the three, get as much oil off the surface as possible by wiping.:)
