I'm putting my Hern Coehorn mortar together and I've been calling around for hardwoods and its going to be expensive. The base is 31" long, 9" high and 15" wide. For best strength I'd laminate a bunch of pieces together. I have basic woodworking equipment, table saw, jointer, planer & such.
I'm near Denver, far from all those nice hardwood forests. I don't think a softwood will work well. Some of the cheaper hardwoods like poplar are also pretty soft. The problem is that hickory & oak tend to go for $3.50 a board foot.
I just wondered if other group members have found cheap sources.
