You have what it takes! But I like something more also. There are many good ideas here.
Do a Googl search for:
"Jewelers Work Bench"
They have all you would need to make including a pullout to catch scraps. They also have a slot for a "Bench Pin" which is a great support for pin drilling and coping sawing, and the filing of things.
Som of the ideas I have incorporated in my benches at home.
