A picture would help... blind advice is don't put any day closer than 1.5" to the HV connection, and any piece smaller than a dollar missing is okay as long as there are no islands. All dag must connect to all other dag any unconnected islands must be connected with a conductor (ideally another layer of dag) or removed... islands arc to each other and that is very bad.

Slip Plate was under 15$ on wallmarts website last I checked...it makes a great dag substitute.
