just go to a circle saw mill

There will be plenty of rough sawn pieces. The Amish or Mennonites may have the old large blade mills. Steam and antique tractor events have them.
Another source might be shipping crates or pallets.
Doing it your self as suggested "might" be a little dangerous and the pattern won't be as visible and will be smaller in diameter. It might work to bend the teeth of a non carbide blade over to one side for that effect. I'd be cautious regardless. :yes:

locally, no.

L L Johnson in Charlotte, close to Lansing has a large mill room. If you call and ask what they use to saw/rip thier boards it may leave a rough sawn look, I donno?
A large table saw with a 16" blade would leave a similar look also.
Search "sawyers" in Oakland or Lapeer counties. Maybe Port Huron?
You obviously don't want a bandmill sawyer and the best I can think of I mentioned.... the Amish or Menonites.

try one of these:

bend one tooth?

It might work to bend the teeth of a non carbide blade over to one side for that effect. I'd be cautious regardless. :yes:

OK, my advice doesn't count? :blink: see post no. 3.
