Spring project; install a NavPod CP20RA & AG225 on a H37c which has the original Edson pedestal guard. The Edson is 9.5" on center with a 1" tube ( I'm guessing here as the boat is in Annapolis & I'm in Nova Scotia ) The system I wish to install is 12" center & 1.25" tube. The problem is that there doesn't seem to be a Top Plate Adaptor to fit the Edson for a 12" x 1.25". I found one for 9.5" x 1.25" (TP125). So, can STARboard be used to fashion a Top Plate for the 12" size and will in be strong enough. Also is there enough room when replacing the original Top Plate with one made from 1/2" STARboard between the top of the Pedestal and the Compass.
