I have two 4 x 10 panels from the 80's and I'm in the process of repairing them. They have 1" headers. I am going to put them on a pivoting frame to adjust the angle as the sun changes position. Is there a method of connecting the two panels without sweating the 1" headers together. I read somewhere about using silicone tubing. I worry about a little movement as I change the tilt angle and most of my repair has been on the ends of the header pipe where the roofers removing them buggered them up. I hope some of you guys will have some suggestions. Thanks
