My father was at the great Dorset Steam fair last week and he picked up this Clarkson Autolock Chuck for me. I’m only getting into milling and have just got an Ajax mill. It has an International 30 spindle. My father thought it looked the same and bought it. It is an International 50 but it has an additional adjustable dial that can be set by loosing a allen socket in the chuck.
I’m not that well up on industrial stuff and was going to sell it on ebay if I can describe it properly or if anybody here on the forum wants it. Although I suspect that it’s far to large for a small workshop.
It seems to be be new but some slight marking on one side of the the taper from being moved around although no scoring and virtually impossible to feel it on it by running your hand over it.
