::: Thumbs ::: Next >> ::: I tried to cut the aluminum with a hand jigsaw, but that was proving nearly impossible. I took the plates to W8WTS at his factory in Ohio at Christmas, he took them home and cut them using proper equipment, FedExed them to W9VA in Chicago, and Bill brought them to Curacao. Here I am doing the installation using deep masonry anchor bolts and lots of caulk adhesive and sealer.
