Cherry HF with Walnut Colllar? - Woodworking Talk

I love the way cherry works, especially hollowing. Here's the first piece I did out of that cherry I got. Question: What is the proper way to add a collar to this type of piece?

Most people simply glue a piece on. This is an endgrain joint on a lot of hollow forms so I prefer to cut a shallow groove in the lip and then cut a matching tenon on the contrasting wood to match. This forms a much stronger joint and won't break with wood movement.
You can have wood movement actually break the collar with either method if the collar is large enough. In this case it's better to match the grain direction with the collar but that can be tough to come up with since most of us only have side grain wood large enough to do the larger collars. I think anything under 3" is pretty safe but I usually hollow through holes that less than 2 so I don't have a good comparison.
I used to make roughly 6" bowls with contrasting lip woods and had several that open up cracks during the dry season. These were segmented bowls with side grain lips and the wood movement is different between these two. I learned to make segmented rims with the grain running in the same direction as the bowl wood to prevent this problem.

Tim,
Nice job on the HF. I too like cherry to turn. John, good explanation on the rings. Might have to start calling you 'lord of the rings'.

Thanks John and Mike. Obviously I just glued a piece on top but that set up seems really delicate.

Tim, that is realy nice! I love the shape and colors of the woods used. How big of a piece is this? What did you use to hollow with? I haven't done anything like this yet but hope to soon. Great job!

Thanks John (jdixon). It's 3 3/4"x3 3/4". Here's a link to my tools: Every One Else is Doing It, Homemade tools . This is the first time I also used the hunter cutting tip in a hf.

Tim, very nice and with your own tools too!

Is the collar anything other than decorative? What I'm asking I guess, is there a reason you need one after hollowing? Looks great either way!

Next question do you hollow while the foot is on in your chuck much like a bowl and then flip around to finish the bottom?

Thanks for indulging my questions.

Nice job. I really like cherry and walnut.

Thx Eugene.

John, sorry for the delay. Yea, I did all the hollowing with on the chuck, then turn another piece in the chuck to accommodate the top of the vase for a friction chuck. Turn the bottom off from there. The collar is only decorative.
