That's pretty much it, Bob. I did modify my pressure pot so that it is operated at low pressure - about 7 lbs. I also replaced the pressure gun that came with the blast pot with a Husky siphon gun from Home Depot. I supply 80 lbs. of air at the gun and sand is delivered to the gun at about 7 lbs. Using this setup, I can blast for about 30-40 minutes pretty solidly with 50 lbs. of glass bead. It just works a lot better than siphon blasting.
