I want to make a peppermill with a live edge top like in the attached sketch (please don't make fun of my sketch). I realize it will be somewhat uncomfortable to grab, but a friend has a life edge table and I think a mill with a live edge will complement it nicely.

Anyway, here's my problem...... When you have a live edge and you don't want to mess up the live edge, how do you mount it between centers or in the chuck? Seems I need to get it at least somewhat round to mount it in the chuck, so I still keep coming back to needing to mount it between centers at some point. Also, I need to drill a hole in the underside of the tenon tenon that's part of the top, and I can't envision how to mount the live edge end in a chuck. Any thoughts?

You do not mention if the mechanism will have a shaft or be shaftless.

If you have a shaft based mechanism, then you will have a hole in the live edge piece.

I would cut the live edge piece to give a nice flat bottom, then drill the hole for the shaft on the drill press with the live edge obviously "up".

I would then mount the live edge piece on a rod/bolt of the size of the hole, using the rod/bolt in the chuck. I would use a nut with plastic lock collar to hold this on the rod/bolt.

Then turn away as needed.

Yeah ... tricky, innit? :boat:

Thinking aloud here ...

I wouldn't want the top to be spoiled by a screw-down bolt, so I'd go for a shaftless design.

I'd square the blank as best I could, and grip the bottom end in a 4-jaw chuck.

Rough the middle to round, create a double-width spigot that the chuck can grip tightly and part in the center of it -- so both the top and bottom can now be held tightly in the chuck.

Hold the bottom in the chuck (by the spigot you just made, which is at the "top of the bottom") and you can round it, drill it, and all that good stuff. Oh -- and if you make another spigot at the bottom of the bottom, you'll be able to flip it around so you can work the end that you'd just held in the chuck.

The really tricky bit is that you've got a spigot by which to hold the top, but it's at the end you actually need to drill into ... hmmm ... and this is where I'll pass the baton to somebody who knows what they're talking about ... :boat:

My fault for not being more clear.

I would plan to use a shafted Crush/Grind, so although there would be a shaft, it would not extend through the top.

I would use a “crush-grind” type of fitting.
Bandsaw the top roughly to a round shape.
Insert in 4 jaw chuck & drill out the required size hole in the bottom to take the mechanism as usual.
I think it is 25mm. A pin jaws will fit into the 25mm hole & it can then be turned as per normal.
The marks left by the pin jaws will not be seen as they are on the inside. But they could be sanded out if needed.
