Gluing Delrin

Made a cue with a Delrin joint not realizing this stuff is nearly impossible to glue with conventional methods.

Is there any method anyone is familiar with for gluing Delrin to wood and get a decent bond?

From what I can find, scuffing it may help a bit and burning it may as well. Epoxy seems to be a little better than cyanoacrylate. . that's all I know so far.

Thanks
 
I use Delrin for jigs all the time, precisely because ca, epoxy and clear coat doesn't stick to it. Use Juma, phenolic or Elforyn, doesn't cost much.

Apparently Delrin isn't a great joint material in general, so maybe I'll just redo the joint.. Thanks.

On the contrary, delrin is a great joint material. In the 80s I played with a Burton Spain. Delrin buttcap. joint, and ferrule. Ferrule was solid with probably 10/24 threaded rod to attach to shaft. Joint had 5/8 aluminum rod shaped like a tap. Pin was in shaft and that held the delrin on the shaft. I found this out at my opponents expense. He missed a shot and shoved his tip into the hole in the bottom of the pocket. Pushed the cue down and snapped his Spain just below the joint collar. I have no idea of an adhesive used in the assembly.
 
Vertical channels work as locks. If your doing a capped joint. Extend the channels slightly into the cap.

Delrin, or acetal, is basically a self lubricating polymer.... which means most common adhesives will not bond for long, if at all...which is why cuemakers/repair guys use it for jigs, clamps, etc as it can do it's job, then be removed without issue. Cutting channels and such can be a way of holding it in place, BUT does not mean it is 'glued' and will not move. There are some glues that will glue acetal to acetal by basicaly melting it together...but that does not help the cue world in most cases.

I agree with everything you typed. But Mr. Spain and Mr. Heubler still used it on Joints.
