The attached document shows the relative hardness of many species of wood.  Keep this relative hardness in mind when selecting mounting methods, tools, sool speeds and tool feed speeds.

The Janka Hardness scale is a "standard" in the woodworking industry.  Note that poplar wood is almost at the bottom of the scale, thus you may experience issues relying on the tabs to hold your material.

This chart should be blown up and put on the wall. This is a very nice find.

Compliments to Hans for the discovery. There are two similar charts that I had seen in the past that have basically the same information and I can no longer remember the source

If you come across them, post a note here please..
