I have been using my Xcarve to prep some parts for a steel string parlor guitar to be assembled once the heat is on in the house. This is a sitka spruce top I cut with it. I cut a rosette channel and then made a dozen mahogany segments to be epoxied in. I still have to fine tune the machine as parts are off a little, requiring some hand sanding to fit them in. I noticed my new 9mm belts were a bit floppy so I tightened them after this stuff was done. I xcarved a pyramid bridge, radiused a fretboard, and cut out lining with a 1/16" bit too.
