Posted Fri Jul 5, 2013, 6:25am Subject: Air Crazy and 2nd crack...
I'm new to home roasting. I've done about 20 (3.5oz.) roasts with the West Bend Air Crazy. 1st crack is easy to hear. Once it's through I keep listening for 2nd crack but never seem to hear it.
Depending on the bean, I've roasted anywhere ~11-13 minutes, and visually I seem to be into FC/FC+. Everything has tasted quite nice, but I'm wondering with the popcorn air popper, and the hearing of a 66 year old, if I'm missing 2nd crack? I just don't know how far to push the roast and/or the Air Crazy.

I too had not been able to get to 2nd with the Air Crazy popper, until I modified it. This model has a thermostat which cuts of the heat (you might hear the fan speed up / slow down slightly when it cycles on and off). To resolve that I took the advice I found on some other sites where they said to move the thermostat so that it does not cut off the heat. (Of course you need to monitor the popper.) I now get to 2nd crack at about 7-8 mins, which I feel is a bit quick, but I like the roasts better right at 2nd crack. I am experimenting with various length extension cords, a 75 foot cord seems too much as it takes 6-8 mins to first and never gets to 2nd. A 25 ft cord gets to 2nd at about 10-12 mins which seems about right. This is outdoor roasting at 80 degrees ambient temperature. Here is how to move the thermostat: 1) Remove 4 screws from the bottom, pull the bottom off slightly 2) Push the power switch out from the inside, it will still be attached to the wires, later you will pop it back into place. You have to push pretty hard, just be patient. 3) Now you can slide out the motor/fan/chamber assembly. 4) Locate the round, finger tip sized thermostat on the side of the roasting chamber. Use a flat blade screwdriver to pop the thermostat off the chamber. (alternatively you can remove the wires from the thermostat and solder them together, but that is more work) 5) Reassemble the popper letting the thermostat stay toward the bottom of the unit. Total time is 5-10 minutes.
