It would be interesting to know how they machined that rad on the original brackets, whether a milling machine was used or perhaps a shaping machine.
If you mean the convex radius on top of the "cradle caps" it's a rough cast surface usually, sometimes worked over on a belt sander or with a rotary stone (N92 brackets) Some of the early brackets were very well molded and finished, but rough as guts soon became the norm it seems.
“There are invisible rulers who control the destinies of millions. It is not generally realized to what extent the words and actions of our most influential public men are dictated by shrewd persons operating behind the scenes.”
Yes, both Rose Brothers & Dalgleish brackets have cradle clamps that are only cleaned up where needed, & are definitely of two distinct patterns. As it happens a Black & Decker belt sander just gets in nicely on both! I did it approximately 650 times over thirty years on my reproductions (in fact 650 x 4 I suppose, as each bracket has two cradle clamps each with a left & right side).....
The pictures were taken somewhat hurriedly with my phone, but hopefully you can see the minor but real differences in contour between the Rose Brothers & Dalgleish variants. They came out like that pretty much from the sand moulds.
