Making a tenon
Dwight Rutherford
I frequent a couple of Facebook forums and frequently see new turners that need help with making a tenon to fit their chucks. Over the years, I have seen a diagram that shows the importance of turning tenons properly with correct tenon diameter and depth and more importantly how to make sure the face of the jaws need to mate with the flat surface of the blank. Does anyone have this diagram you would share?

I may have some diagrams which I made 6- 7 years ago but I think this is better if you can use it.
Link to Stuart Batty at Vimeo. He has 30+, look for the three on chucks, recesses, and tenons; each are about 12-15 minutes. Very detailed and very clear presentations.

The link below is to the first of two articles on my website that gives my take on the physics involved between a tenon and the jaws of a chuck. Toward the end, I point out the importance of not having the tenon bottom out.
These articles may be a bit much for a brand new turner, and too long and tedious for those more experienced. At any rate, the link is below.

Nice article. But he loses it at the end: "I used to think you could not have too many chucks, but the bad news for tool junkies is that you can probably make do with as few as ten."
Just ten? What was he thinking? :-)

I have but one!
No, I'm not a "real" turner, so I don't really count!

I'm with John. I believe that the number of chucks depends on what you want to turn. My rule is never change jaws on a given chuck unless I intend it to be a permanent change. Life is too short to fiddle around looking for screws lost in the shavings while in the middle of a project. Also, some jaw sets do not automatically align satisfactorily without a bit of tinkering.

I hope Lyle doesn't see this thread. LOL.

>>>I believe that the number of chucks depends on what you want to turn.
This is something not always discussed. Those who never or don't turn often turn things that need or benefit from chucks certainly don't need many, or any.
I sometimes have several chucks on the shelf with partially completed projects. If I had fewer chucks I might be forced to either develop some discipline or take some ADHD meds. Do they make meds for ADDHHHD?
>>>My rule is never change jaws on a given chuck unless I intend it to be a permanent change.
Great rule. With this rule you don't even have to stick to the same brand of chuck so you can interchange jaws. I recently bought a new jaw set so the simplest thing was to get a new chuck to go with it. I hope having 16 chucks doesn't make me a bad person and make Raffan decide not to visit.
