So after watching Aarons recent YouTube video on bone dry air, I decided to share a picture of my aftercooler setup that I recently finished. I used a 10 x10 transmission cooler with AN to NPT fitings to connect it to the copper lines. As you can see in the picture, I put a water separator at the lowest point to expel any accumulated water each time it runs. I used a transformer from Amazon to convert from 240V AC to 12V DC, pulling off the compressor supply, converting it to 12V, so now the fan cuts on whenever the compressor receives power. The temp of the cooler intake line runs over 250F, but coming out of the cooler is only 84 degrees, and by the time it gets back to the tank, is about 75F. After 2-3 days of running here in NE Tennessee, I drained the tank and only got 1 oz of water out of it. I hope this helps someone.

I am working my way through the classroom modules. I don't have my booth built yet, but I have a plan. I've got a dozen 2x4 ft LED flat panel lights ordered from Home Depot that I plan to use for lighting (5000K, 7800 lumens). My booth will be 12x24 ft, so I was thinking of putting 4 lights vertically on each side, 2 longways on top, and one horizontally on each end, at a 45 degree angle up tight to the ceiling. Does that sound light it would work? Any and all suggestions appreciated. Also, in the tutorials, it was mentioned, "Make sure that your side lights are positioned at 20-40° angles, so defects create shadows you can actually see." Does that apply to flat panel lights, too, or am I overthinking things, as I tend to do? Thanks.
