Paul Sellers bench
I am considering building a Paul Sellers style woodworking bench. I am thinking that a 3 1/2" top (ala laminating 2x4s) is the right (and typical) thickness for the top.
So I went over to my local Home Depot and was looking at the options for stock for this thing. I could go with 14 pieces of 2x4 construction whitewood, 7 pieces per side. With the aprons, that would give me 24" of top (not including the well width). That is the most conventional way to go.
HD also has these 4x4 Douglas Fir (NOT pressure treated) pieces, 8 feet long. So I could do something like 4 of those on one side of the well and 3 on the other side. That would give me 15 1/2" on one side of the well and 12" on the other side (after adding in the width of the aprons). Unfortunately, the edges ARE rounded over, so I will have to plane or rip them off as well.
I like the idea of the Douglas as it would save on the glue-up time and effort, and they are a nice brown color.
Compared to whitewood, is Douglas easier/harder to work with, from the perspective of cutting dadoes, mortises and tenons?
Are there any other down sides to using 4x4 Douglas that I am not aware of?
