Here is a S & P mill made laminated with oak, walnut, wenge, birdseye maple, bloodwood, & redheart. The laminated stack was cut at 8 degrees rather than present it as a straight stack. For a 3" square you will need at least 4" of laminated area.
This S & P mill was made with walmut, oak, birdseye maple, and the celtic knot is bloodwood.
I am using a new finishing process on these mill with Waterlox sealer and finisher. A total of 3 coats with the second coat sanded from 1500 to 4000 before applying the last coat. I made a special fixture to rotate the body off the lathe which permits me to continue to make mills and wait the 24 hours between coats. I can post a picture of the fixture if anyone is interested. I was really satisfied with how the oak turned out on he lathe.
