Your best bet is a urea resin glue such as :-

PVA’s can lead to creep with the joints moving, don’t take my word for it CHJ who sadly doesn’t post anymore was a prolific segmented turner, here is a post of his to someone struggling with movement in PVA joints.

Beware, Cascamite is very hard when fully cured and will blunt your tools quickly. My turning experience is limited but PVA has always worked for my simple glue up situations. I've seen several videos of glueing up for segmented turning and invariably PVA has been used.

Not all PVA has creep (the modified D4 PVA glues are more prone to creep but not all) I would agree with Doug B that a urea resin is a good alternative. If you are sticking with PVA then I would suggest trying Everbuild 502 as an alternative to tightbond 3. It is stated that Everbuild 502 can be used as a structural glue Tightbond 3 states it can not, apart from that, they seem to conform the the same standards.

The second link I posted above was a thread on here from a chap experiencing creep after gluing up with 502 on a turned piece

Interesting, if you store it for periods you should always stir the contents as they can/do settle.
I have used Everbuild 502 on stair treads that were installed in offices with no sign of creep after 3+ years.
The technical sheet about Everbuild 502 does not mention it is suitable for structural applications but I did read on a site that was selling it that it was (might be one to ask Everbuild). Tightbond 3 technical sheet states it in not suitable for structural use.
I would go with The Urea glue for a cutting board also...I recently did and purchased it especially for the job even though I had Everbuild 502 to hand.

To be honest creep is minimal & not something I’d particularly worry about in joinery but on turned work that is going to be handled it can be very noticeable.
Years ago I went to a lot of time & trouble gluing up a bowl blank that had Xmas trees glued in segments all round the outside of the bowl, unfortunately I glued it up with PVA & weeks after finishing the bowl I started to notice I could feel the joints where previously I couldn’t.
The joints weren’t opening up they just weren’t perfectly flush with one another anymore which was particularly noticeable to the touch, to say I was gutted was an understatement.

That was probably due to the wood drying out. In which case something has got to give; either the glue moving or the wood splitting.

it was definitely down to some stress in the wood but as CHJ explained urea resin would have prevented this, we are talking very minimal movement
