I bought an used Workbench a few days ago, the top is in yellow pine, 2-3/4” thick and let me tell you, that thing is hard!
Most of the lumber at Home Centers are intended for construction, cheap stuff, so the quality is not the best. I suggest to look for Hardwood suppliers that also carry SYP and Douglas Fir for the Doors&Windows Industry.
