After looking at various types of commercial adapters, they looked to be pretty straight forward so I had a go myself.
Mine is designed for the Nikon 4500 + Kowa 823.
Simply take 4x 49mm filter mounts (I have loads of these from my 35mm & B&W days) - screw them together. Epoxy glue a 28mm -> 37mm step ring to the inside of a 37mm -> 49mm step ring and file off the inside (37mm) lip of the step ring to enable closer positioning of the camera lens to eyepiece. Screw the step ring to the filters though you could glue it in place too.
In the second in filter from the outside edge simply drill a hole to fit a flat ended screw. Prior to drilling, fit the mount in place on the camera and mark the top surface where to drill the hole. Use a plastic or metal screw just as a lock screw.
There you have it.
Screw the 28mm end to the Nikon, the mount easily slips over the 32xW eyepiece like a glove and locks in place using the screw.
If you are wondering why those step ring sizes, it's because they are readily available of the shelf for £4.90 each plus £1.95 p&p !
