Loose Bogen hex plates

[paulr]

By gluing a layer of 1mm aluminium plate (cut to size and drilled) to the bottom of the hex plate the problem was solved.

Brilliant!
I may be able to just glue some strips of some sheet metal in a couple of key points.

Solved, with padding of duct tape on the bottom. Aluminum would be sexier (not having the problem in the first place would be secier still) but this was a 2 minute fix.
