Need help with framing

I am trying to use luan doors for my inside walls and plan to cut them off at the top.
I would apprectiate it if someone could lend advice about how much framing to replace inside the doors. The doors are very light and 1 1/2 thick. Slightly less than 1/8 vaneer.
I made my table today of heavier doors. Need a place to work
. Kicking everyone out of the sewing room/office was nixed
So I am stuck in the stinky kerosine garage
( I know, I am grateful to have a garage and people who let me use it and a heater. At this rate I'm gonna be a sainte.
any advice would be appreciated.
