I have a mystery 16mm drill chuck almost certainly of chaiwanese origin that I can't find a taper arbor to fit it.
I don't have the equipment to measure the taper apart from to say that the socket is about 17.7mm at the large end.
A JT6 taper is too small by a small amount and the next Jacobs taper up, JT3, won't even start to go in.
I've looked at the B16 taper and that is far too small.
I've spoken to Arc Euro and Chronos about it and they have been unable to offer a solution.
Has anyone any suggestions please. I'm beginning to think I'm going to have to make one.
TIA
Bob
