Hi Jim,
This fastening of the hinges was shown at the original model of the Trinity House:
The brass sheet goes around the back of the rudder and ends, where normaly they had to carry the gudgeons.
I do not know why the original model maker chose this obviously wrong solution. But Robert Spence has also attached his ruddder in his copy in this way. And that's why I want to do it alike.
It looks like the connection was made by pieces of wire, which rests in the wood of the rudder on the one hand and in an eyelet on the stern post, which was formed by bending the brass sheet. I cannot bend the brass so accurately. So I solderd a piece of brass pipe to the brass sheet instead.
That's the way I want to do it. I will make the final attachment of the rudder later, otherwise it could easily be torn off.
Early Navy-Board models show often primitive forms of fastenigs of the rudder. This is mentioned by John Franklin in his book "Navy Board Ship Models" (see page 42). Maybe soldering was unknown?
Here ist an example at an model of a Royal yacht in the NMM:
Cheers, Alexander
PS: Sorry, but I don't know, how to turn pictures upright.
