I am planning to make some frame and panel doors for a project at our
church. The doors will be painted. The doors will be tall (85"). I
haven't done much with poplar other than a cabinet and shelves that
needed to be painted. If I rip the stiles at 2" wide and 85" long will
it spring apart or together like cheap pine does?

Just to answer a possible question you might have in advance, each door
will only be 17" wide but very high as I pointed out.

Poplar I have ripped did neither, that was about 100 BF. Now that does
not mean anything really.
