B type tapers

[mares]

Hi,
Can anyone help me with the dimensions of the B type tapers? Drill chuks use this type (fe B22, B18, B16 etc). I want to design an dadapter to that. the only I know is the number after the B is the bigger (major) diameter of the cone in mm. At B22 fe it is 22mm. I know there are adapters from B taper upto Morse tapers, But I need at least the cone angle if anybody can help.
thnx

Mares,

I am hoping that "tapers" are the same thing as a tap.  My opinion is that if you are designing a mechanical "adaptor" for a tap, go to a machinest forum.  They specialize in this subject and are as helpful as these guys are with electronic questions in this forum.
