Mount K5 DVR on 1/4 inch thread?

Thanks. I actually thought about using an adapter like that one, but I identified a couple of problems with it that made it seem to be a less than ideal solution.

Thinking about it some more, however, I think I can make it work.

One problem is what if the M6 bolt on the adapter is too long? I think I can just hacksaw it and file it shorten it up however.

The main problem is how can I stop the DVR rotating on the M6 bolt? I need it to keep pointing in the same direction. I'm thinking I can just use a blob of glue to hold the DVR in place against the adapter. I'm thinking hot glue.
