[R-390] MB (Mini BNC) connectors

[DW Holtman]

I recently acquired some very high quality Coax (RG-188) from one of the many helpful members if this group. Does anyone have any helpful hints on rebuilding the straight MB connectors? The 90-degree connectors look easy. However, the straight connectors look much more difficult to rebuild. 

Is the coax shield attached with a crimp? I have opened one up, but I'm a little bit nervous about tearing it apart,for fear about breaking the part holding the braid behind the pin.

Does the small Teflon ring that rests at the base of the center pin installed before or can it be put on after applying the heat?

Any help would be a lot of help.
