12pdr bandstand platform for Torpedoboat destroyer

[WW1 TBD Decking]

I am scratch-building a 1/72 scale TBD (HMS Violet) and have come to a problem, namely making the circular wooden gun platforms made from slats, like a wheel, with the gun mounting in the middle. There were 2 of these on Violet - over the Conning Tower and near the quarter deck. They are 47mm diameter
 

Has anyone any nice ideas how to construct these bandstands? My efforts to date are just too crude to pass muster. Any help would be really appreciated!!

I don’t know how well equipped your shop is but I would make these from metal- soldered brass.  I would start by using K&S brass shapes in order to get consistency.  The circles could be made from slices of brass tubing.  The solid center could then be filled in with a wood plug, bondo, or some other modeling paste.  Simple wooden jigs can  be made for alignment.

I did consider brass but I need to keep the top weight down but i think I might try an
