Marty, you can easily make a pressure pot to place the casting in after you pour it, to help remove the air bubbles. I just use paint pots (widely available on eBay & online) and pressurize to 35-45psi. I KNOW you HAVE to have an air compressor, so a modified paint pot should be a snap for you. It will help remove the air bubbles from your castings. After you pour resin in the mold, just put it in the pressure pot, secure the lid, and pressurize away. I have the best results around 35psi. It even works with some RTV/silicones.

When you have your mold halves apart, look at each half and visualize that as the resin goes in, how will the air be displaced? Visualize the trapped air rising to escape the mold, and that should tell you where to cut/place your air vents.

Keep up the good work & post your results please!!!
