Calvin Arterberry Posted October 27, 2015 Report Share Posted October 27, 2015 I am green to turning. But I do love it. I am having trouble keeping my brass tubes glued to my blanks while I am milling them with my barrel trimmer. Any advice guys? Thanks.

wdwerker Posted October 27, 2015 Report Share Posted October 27, 2015 Maybe scuffing up the outside of the tube would give the glue a place to grab. Quote Link to comment Share on other sites More sharing options...
Calvin Arterberry Posted October 27, 2015 Author Report Share Posted October 27, 2015 I have been scuffing all the tubes before gluing. I actually scuff them pretty good. Quote Link to comment Share on other sites More sharing options...
duckkisser Posted October 27, 2015 Report Share Posted October 27, 2015 what do you use for glue? my problem is the superglue dries too fast so sometimes the tube gets glued in half way Quote Link to comment Share on other sites More sharing options...
Calvin Arterberry Posted October 27, 2015 Author Report Share Posted October 27, 2015 I use a gel ca. I put some in the hole then some on the tube then insert it and twist and turn the tube to try and get the glue all over the inside of the hole. Then I spray an excellerant in the hole.

Miles11we Posted October 28, 2015 Report Share Posted October 28, 2015 Do you mean the tubes are breaking loose after gluing? If so, ca glue (and epoxies) will break loose with heat (i replace the hss bits in my hollowing tools like this), could you be generating too much heat in the tube? You could try slowing down, cleaning up the bit regularly and mayb a bit of beeswax, bladeglide, or something on it for friction. .. or even polishing the part that has to ride in the tube and doesnt cut to take it down a few thou and make er slippery.

Barron Posted October 31, 2015 Report Share Posted October 31, 2015 You didn't say what wood you are using, but some tropical woods can be hard to glue due to oils in the wood. You might try dipping a cotton swab into mineral spirits and passing it through the hole a few times. Some drill bits are slightly off than the marked size, so trying a different brand of drill bit could help. Also, I have better luck with 5 minute epoxy than CA glue. Hope that helps.

TomP Posted November 14, 2015 Report Share Posted November 14, 2015 You have to scuff the barrels up with 220 then glue them in. Make sure you use the correct drill bit. If it is a slim pen you need a 7mm bit. Quote Link to comment Share on other sites More sharing options...
Mike M Posted November 15, 2015 Report Share Posted November 15, 2015 I gave up on CA glue for this application. I switched to epoxy and haven't had a problem since. It takes longer to harden, but so does throwing a blank away because the tube broke loose. 1 Quote Link to comment Share on other sites More sharing options...
