Can anyone recommend a place to get some 18mm Baltic birch cut to spec? B&C has just published a box design for the two 14" coax's I've had sitting on the shelf thru Covid times and my woodworking tools beyond a chop saw are in storage. Ideally someone within a three hour drive of DC. On a related note, can a US based shop be expected to work on metric designs or should I count on reworking them as Imperial measurements? I have to work up dimensions changes for dadoes anyway.
