The Tobin bolting is not at all a rotary bolt a la A.T. Brown. It is a bolt that rotates horizontally. See Part # 16 --
Thank you Reasearcher.
I have not seen any where a diagram of the actual working of this Tobin bolting system.
I can sort of imagine those parts together to hook over the square hole in the rib extension & hold it down, a bit like an L C Smith.
What I cannot see is any taper or other way it takes up wear & remains tight like a Smith.
Does anyone have a cut away drawing of the assembled action bolting system ?
O.M
