Can anyone explain to me about wire threading tenons and ferrules? From what I have seen they look to have about the best fit of all tenon ferrule combinations.
wire threading....???
- Thread starter kickshotkid
- Start date
It's just wire like inserts to strengthen the threads, helicoils are the most commonly used I think.
Based on what? I'd bet they would eventually bind on the pin and then destroy the parent wood in the process of removing the shaft. It would happen, just a matter of when. Wood is too soft for wire inserts.
No, they are a modified thread that is shallower than standard. Gives more meat on the tenon and ferrule material. Thought I had a picture of one of my tenons but can't find it. I'll just steal DZ's instead.

Murray edited his reply with the close up pic just as I was posting. I will add the link to the page that pic comes from. Last two paragraphs. Requires yet more custom tooling.

Hey, I stole his picture first!
I do mine a bit different. I'll have to take some pictures later.

I guess you raced your iPOD faster than me. Don't force the issue. :grin-square:
Yeah I missed the ferrules and tenon part of his question. Looks like a good joint, lots of glue surface. I've never used that.
Ya that's exactly what I'm talking about, with the strength and fit you wouldn't even need glue. There must not be very many cue makers that do or know how to do it cause I haven't been able to really find any info about it. The threads looks kinda like compression threads.
That makes sense, makes me sad to look at my 5/16 18 compressed tenons lol. I agree he shares a lot a lot of great info and his cues are gorgeous.
Cool, I would love to see some pictures of how you do yours. Do you use a 3/8s tenon as well?
Here are my threads. Did these real quick to show the concept.

3/8 11 ?
Did you ground the live threader to have .030" edge ?
That is 5/16-14 but I also do 3/8 on some materials. I just made dies for the shaft side. Live thread the ferrules.
So I can live thread the ferrule with standard tooling. I've put up the video before. You can find it on my utube BMT1968
Murray, I guess it doesn't make a difference then, structurally, whether the "meat" is on the ferrule or the tenon?
The ferrule material is stronger than the wood so I think it would make a difference.
Yeah Chris, common sense would seem to promote that but then again when combining materials maybe common sense can be thrown out the window.. I really don't know..
