I am having trouble when it comes to cleaning out the tubes of my blanks after glueing. When I prep my blank I use thick CA glue to glue the tube in. When I put the tube in I twist to distribute the glue and then I let it dry over night. When I come back the next day to clean out the excess glue the tube continues to be pushed out. Sometimes I am able to get the bit through to ge the glue but when trueing the ends up the tube pops out. What am I doin wrong that it causing this? Its becoming a real pain to continuely reglueing.

i use some sandpaper and scratch up the tubes before i glue them in, this works for me. it gives the glue something to stick to.

Heat breaks down the chemical bond between the tube and the wood. Try using a different type of glue

I’ve had that happen a few times, and it usually is due to overheating the tubes… try to slow down your drill press to keep from heating it up.

Also, scratching the tubes up with coarse sandpaper is advised, and on oily woods try using epoxy instead of CA.

Try using medium CA. Also, are you using an accelerator? I scratch the tubes with 120, put a ring of glue on the inside end of the blank that receives the tube, liberal coating of glue on the tube, twist while inserting to insure complete coverage, then hit both ends with the accelerator. Wait about 5 minutes, cut the excess on the table saw and square up the blanks with a barrel trimmer. This works for me.

i use a small round rasp to clean out my tubes before i use the barrel trimmer. i’ve also went to epoxy. if your letting it sit overnight a 15 min epoxy gives you more time, fills any gaps better and is very strong. i give it an hour after glue up without a problem.

Play dough is your friend. No don’t take the kids, go get your own. Take a glob of play dough and flatten. no take the tube and stick it in the play dough and twist abit when you pull it out. You now seal the ends so no glue gets inside. After the blank is dry just push the playdough out and use the mill. I too have used epoxy and have never had a failure.

Ditto on what Rick said. Try letting the blanks cool down for a while after the drill press before you insert the tubes.
