I cut a couple of the ornaments finally, had to buy some proper blades and my top chuck head decided to quit working properly. Anyway I cut the letter out first and filled with epoxy. This worked ok, but air bubbles get trapped in the letters, really need to use a pressure pot. The epoxy cut very easily and fairly clean (used a Pegas #6 super skip), after cutting the piece out I them sanded the epoxy to 2000 grit, finishing with tung oil. Wood is mahogany.
