The blanks were left overnight and this morning I began to true up the ends. On 2 of the 14 (interestingly it was 2 halves of the same blank) the tube separated from the blank while trimming.
I am sure there could have been something stupid I did but for the life of me I can see what. I think I am going back to CA. I have had a few blow outs with CA glued blanks but I put that down to poor skew technique on my part and probably not enough glue.
You live in Phoenix. And, as your sig says, "it's a dry heat." I've used Gorilla Glue without any problems on about a dozen pens. I scuff the tubes, wipe 'em down with alcohol. I run a
wet Q-Tip through the blank, making sure that the entire inside of the blank is moistened. This also serves to get any residual dust out of the blank. I use another Q-Tip to smear Gorilla Glue inside, then slip the tube in. (The tube does have plugs in both ends.) Set the whole thing down on wax paper (foam out can get messy) and move onto the next one. If you're concerned about tube movement (it can happen), just put painter's tape over the ends of the blank. Like you, I live in the land of dry, which is why I moisten the inside of the blank. IF you don't, then there may not be enough moisture for the Gorilla Glue to cure properly.
It IS messier than CA, but no problems with sticking your own fingers together, no problems with getting the mix ratio right like Epoxy needs, no problems with CA sensitivity.
