I need to make a 2 piece cane so my father can pack it in his suitcase when he travels.

I have the joining hardware, and will be making it out of dymondwood.

Do you rough turn then cut with a parting tool?
Cut and join prior to turning and keep the spindle steady there?
Finish turn but not sand then cut and join then sand out the difference?

Thanks in advance for the tips
John
