Its a strange piece of wood, for sure.

Poplar is a deciduous tree and therefore classified as a hardwood species. However, the stuff that I can buy is not 'hard wood' by any stretch when comparing it to woods like oak.

The Kregg Jig company recommends a coarse threaded screw for poplar.

I stand corrected.

I will say that I didn't have any problems with poplar splitting or over-torqueing screws using Kreg pocket hole joinery.

Now back to the topic at hand.

I stand corrected on the screw length.
