if the owner just drilled and tapped the frame and the plug at the same time it would work. I would probably do that just to make sure they don't jump out with a weather change or something. I'm interested.
I was thinking the same thing but I was just trying to make it easier for everyone. I wouldn't mind leaving the drilling and tapping to the owner. I even thought about making some out of aluminum. They would be much easier to drill and tap. I went with stainless because the polish holds up 10 times better than aluminum.
