I hate the standard trellises. I think they are ugly and cutting them to shape is a pain, usually resulting in splinters.
This one is made from spruce 1 X 4 's that I resawed in half on the bandsaw, since I didn't have a table saw at the time. The "apex" is bolted together with threaded rod and nuts, the ends are screwed to the breezeway and then trimmed to length with a handsaw.
Unfortunately the nasturtiums that we planted at the base last year didn't climb. This year we will try morning glories, hopefully they will do better at hiding the industrial area from the residential section of our place.
I was going to use my radial arm saw to rip the boards, but because they were 8' long I would have had to swivel the saw to get enough length before then ends hit the door. Bad idea. Too much wiggle. Just because you can do it with the RAS, doesn't mean that you should.
