It is a mount that I designed a few years ago. Prety simple to build and very "symmetrical" looking for those customers who don't want a gawdy looking pedestal and a giant white box blocking their view.

It often requires a taller pedestal guard so I often use the Nav-Pod SG-10 1" straight guard.

It is simple to build:

*Cut the overall size you want the platform to be out of 1/2" Starboard

*Drill two 1", 1 1/8" or 1 1/4" holes (depending upon your guard diameter) 9.5" on center

*Buy four 316 SS "clamp collars", in the size you need, from McMaster Carr. 1" 316 Collar is part # 9633T19. They make them in 304 but they will rust faster even after polishing.

*Use a buffing wheel on a bench grinder and tripoli compound to polish the clamp collars (they come "mill finish")

*Pick your radius corners and cut them using a flush cut router bit and a template for the radius

*Use a round-over router bit to chamfer the edges for a nice finish.

*Slide the upper clamps on

*Slide the mount board on

*Slide the lower clamps on

*Mount the plotter bracket

*Drill the holes for the wires

*Drill a 1/4" hole in the guard tube

*Use the 1/4" hole as a guide for a Lenox hole saw to make hole bigger

*Use a dremel to smooth hole edges inside and out of the guard leg.

*Buff guard leg around hole with buffing wheel

*Adjust desired height and lock the collars down.

*I also replace the crappy black plastic Edson feet with the newer SS style
