Question on dimension sizes

[Danh]

Hi Guys

I am beginning work on a project with a dual time movement, Ranfft is such a great site for information, there is however a dimension I am possibly staring at, or can not find, specifically the height of the stem hole in conjunction with the depth of a movement.

on Ranfft it gives dimensions that may be this, and if not would anyone know how i can ascertain this information (what does F and T refer to please?).

This information below is stated for the ETA 2893-2 (2892A2)

11.5''', Dm= 25.6mm, Do= 26.2mm
H= 4.1mm
(ball bearing +0.1mm)
F= 1.6mm
T= 2.0mm
21 jewels
f = 28800 A/h
power reserve 42h

Many thanks

Dan

 

Edit: Its ok, i just found the information
