I put this temple together today from hard maple, made a 1/8" brass pin with an eye for a handle, made a SS sliding band from a band clamp and I used finish nails inserted at 30 degrees on the stretchers. I drilled all the way up the length of the outside piece as it was easiest to line up the holes in the insert (middle piece). This is not needed and the plans do not call for it. The outside piece just needs on hole drilled through and through as the falcrum on the end. Anyhow, doesn't detract from the piece in my opinion.

This will actually extend to 65", but as I understand it you only go out to within 3/4" from the edges of the weaving.
Enjoy :)
