Andrew, you mention Santa getting you an XY table, god for positioning work for drilling, but don't think that you have a mill, how ever light. You must have a proper chuck, or collet system, with a draw bar to retain it, and don't try using a Jacob's chuck to hold milling cutters. You probably know all this, but there are beginners out there (like I was) who don't. When I started I put a 1/4" end mill in the Jacobs chuck, and just near the finish of my first job (a tap wrench), the chuck fell out, Stop work, find out why, go buy a collet chuck. Still got the tap wrench.
