Thank you for the beautifully made CB bases. I was a little worried about the final fitting with the pipes but shouldn't have been - the pipes fit perfectly and installation was easy! I've been photographing the sky ever since, and it has gone from greyish (no clouds, just pollution) to blue with white wisps of clouds and now it is just blue. I will start busting the surrounding area soon and will keep watch. Delivery was swift, packaging good and lovingly done. VERY happy with these, and with OA. Thank you so much!
