I'd be happy to take any pictures you'd like. It'll take a little while, however, maybe a week or so.
Inletting - the key is not just skill, it's having the right tools and patience, lots of patience. You can deepen those escutcheon inlets with no damage by just taking your time and doing just a little bit at a time. Make sawdust, not big chunks. When it seems too hard, just set it down and go away for a while, take a rest and get back to it later. There's no deadline. As far as tools are concerned, use ONLY very sharp knives, gouges and scrapers. Visit a woodworking tool online shop for ideas. If it were me, I'd go to Brownell's site and get a scraper, and just scrape the bottom of the hole over and over until it's deep enough.
