Your right it would be a small nightmare to make..I've an idea would it be possible to make a Linn type mounting collar with a specified diameter bore?

I don't want the scoupe in it as pictured but i do want side entry grub screw. I could try get one to work from! Only requires three tapings undeside for fixing to deck.
