threading

Anyone have a diagram of how to tie joint threads?

That is one of relatively few addresses I have book-marked. It says a lot, well.

Thank you very much for that link.

You’re welcome!

Hi Walden,
What I like to do is get the thread thickness right by trying it before i cut it, then I just loop it once and hold the loop and run the free end through several times like a slip knot, then pull it tight and let it get buried in the layers, cut it off flush. Put a little cork grease on it to keep it tied. You can find the end by scratching the thread with your thumb nail until it surfaces.
I like this better then just letting it unravel all the time…

Hey, my flute’s got cork!

Sorry I haven’t gotten back to you, Jon, although I’ve been watching your silver exploits. This flute’s a corker!

I’m for cork.

Is that to say you are putting a cork on this thread?

:smiley:

Corks get screwed. And pulled.

Re: the thread thread… you have three choices when finishing a thread lapping:

  1. just leave it “open”, well greased down - this is a good idea on a newly lapped tenon as it may settle a bit and you may want to adjust it by adding or removing a few turns.
  2. throw in a few half hitches on the last two or three turns of thread - in the direction of winding. That will stop any propensity to unwind easily, but again it will really be the grease that holds all in place.
  3. do a proper “whipped” finish - lay the free end of your thread vertically on the tenon over the lapping already wound and, with a decent loop of thread left free, take the last half-dozen turns over the free end, then draw the remaining slack through and cut off the end flush - tidy, won’t come undone, but rather permanent and difficult to re-open, so only do if confident you’ve got the overall lay of the lapping right.

Hi Kevin,
I mainly do the thread on the antique flutes. It serves two purposes, one to seal the joint, the other to bind the tenon for extra reinforcement. Some of the old tenons need all the reinforcing they can get!
Kind of out of business at the moment, after getting my achillies tendon worked on. (no cork or thread on this tendon…) Off my feet for 3 weeks! :sniffle:

I will have to try the third option, that sounds like “the bees knees”. I have done this with wrapping bansuri flutes, but not with tenons.
