I’ve got a client who needs a hinged shank due to severe arthritis.
She has fairly large fingers and the target size is 10.5 (Actual
finger size, not the knuckle size).
I have been looking at the available commercial offerings -
Superfit, Lockshank, and Reller’s Dovetail. Size 8 is the maximum
available in any them (which seems completely at odds with reason
since they’re designed for people with size issues).
I tried sizing a brass Superfit up just to see what would happen.
It went to the 10.5, but the locking mechanism clearly suffered and
the two sides no longer fit invisibly at the lock or the hinges.
I doubt that it will last as long as it should.
Any suggestions or comments on a solution would be appreciated.
