During my prototyping for some plaques, I wasn't getting the look I was going for so I tried something different. After the plaque was cut, using centerline text and a 60deg V bit, I mixed some black paint with drywall mud and filled up the letters. After sanding and staining, the letters almost look inlayed. The stain soaks up much more into the letters, producing the high contrast i was looking for.
Just thought I'd pass this along, as I always love to read little tips and tricks in the forum.
Happy Carving.......
