Step 1 I buit my box in no time.
Step 2 Profiles in place and hole drilled just below center.

That looks great. Any temp readings?
I haven’t got the system fully connected yet to a permanent fan, but with an outside temp of 61 degrees, and an inside temp of 55 degrees I used the blower on my shop vac to push air through the system and got a reading of 111 deg on the supply side. My blower was putting out a wind speed of 57mph which I had directed at the return side from a distance of 5ft away. When it came out the supply side I got a reading of 6 mph. I havent put air through it for a prolonged period to see how long it could hold that kind of temp, but will post another reading when I get the permanent fan hooked up and we see the sun again, 2 weeks of rain forecast here in Northern Cal ,grrr.Sae la vie
