Planer board mast

[river_walleye]

Does anyone make a Planer board mast that locks into the wedge style seat base? It probably wouldn't be all that hard to make a mast, but by the time you buy all of the hardware like the large reels, it is probably cheaper to buy one? :confused:
Thanks

My big Jon duel mast fits into my center seat hole up front with a wedgetype hunk of aluminum and an allen screw that enters from underneath. My boat type is Lund and it came with my rig when I bought it.
