Hi Chris - Thanks for your comments on my shop. At your age, experience, and shop set up, you have a real jump-start on most of those who aspire to be cabinetmakers. I'm sure you will do well.
Here's a thought you may or may not find useful. I installed the "Long Ranger" system a couple of years ago for my dust system, and think it's terrific. That's the low voltage, wired system that starts and stops your collector as you open and close the dust gates. It uses a micro-switch on each gate that operates a relay into which the d.c. is plugged. I can only assume it would work with the current you use. It's sold by Penn State Industries, and is relatively inexpensive.
