The floor is in my house and is butted-eased edge-with biscuits/ dominos .
On some planks I put relief cuts in the back.
The edges were done one at a time with a joined together festool straight edge- circa 18'.
I V carved poetry in the floor on the shopbot and filled it in latter with coloured epoxy.

It was a bear to do and I blew up the cutterhead on my 16" hammer j/p and fried the feed motor on my woodmaster sander.

My thinking started like yours when the lumber arrived .....I probably wouldn't do it for a customer, but would do it again for myself.

Major brownie points were scored with the wife.....put a value on that!

I hate working Jatoba! think Byrd headed planer or kobalt tooling

Good luck!
