Thanks, I will be sure to give a review when it arrives and I start playing with it!! Hopefully it will come in today!!
As far as the cook top, here was my idea.. Take some 1/4" angle iron and construct a frame, with the flange facing inward toward the center of the firebox. Cut my cook top to sit inside the frame and have a 1/4" gap between it and the firebox. Cut a 2-3" hole in the center of the firebox top and use some 1/4" flat stock as a "damper" coming out thru the angle iron. With the cook top tacked down over the damper, it should keep it sealing to the firebox nice and tight. On one corner of the cook top, cut and weld in a 1" threaded nipple to serve as an exhaust for when the damper is open. It would really allow me to pull heat under the cooking surface and I could screw on a test cap when I wasn't using the cook top. Between the seal n the firebox top and the screw cap, I would think heat loss would be very minimal. How does that sound to u guys?
