Tennon Material

When I purchased my lathe it came with a bunch of NOS stuff. Mostly about 3 years old. I have been having issues with the replacement tennons twisting off near the cue face. I have both a steel and an aluminum compression die. I use wax and the proper technique. Do most of you use fluted, spiral cut, or straight dowel that you thread yourself?? I'll do a few with good results and then one will twist off

I’ve not had much luck with those tenon threaders either. As a friend of mine suggested, I use a split die with very good results.
 
Is this about replacement tenons? I’ve had no problems with 2 part epoxy. Just wait until it has cured completely. The replacement tenon should not twist at this point.
 
To be honest, I only have done one, but got a very nice result. I had a house cue that I was using as a break shaft and it's regular tenon came loose so I bought some capped threaded tenons and one of those threaders, watched a few videos and did it. I actually got quite good threads for what it was. I didn't use as much wax as I saw used by others with the thinking that I wanted as little wax on the threads as possible when glueing. Then I made sure to use a longer setting, not 5 min , epoxy to glue on the tenon. Let it cure for a few days and has been fine ever since and I use it for breaking.
If I had a machinist lathe, I would only do cut threads, but I don't so just had to make do with the lathe that I had.
 
I found the tenon threader made the threads a lot smaller than the tapped ferrule leaving a lot of glue filling the gaps. When I switched to the die I could make the threads larger and use wood glue instead of epoxy on some materials.
 
Live thread cutting is the best option if you can set that up. Plenty of video's and posts of how different one do it.

Cut the tennon down to around .29 then it will thread fine and you will have no issues. I think those premade tenons
come @ ,31 , you might be surprised at the difference a few thousandths makes.
When they are too big the die gets in a bind and makes them twist off, nowhere to get rid of the waste that you cut off. a little looser thread works good, giving you more room for glue

i make my own tenons, maple always seems to be available in the shop,.

5/16 18 tenons need to be cut down to .285". NOT .312 IF YOU USE the die .
IF that is a metal lathe, get yourself a router setup.

Yup.
