Stripped BNC Cable
This is a photo of a RG 58 cable that is stripped to the specification that are on the label of the bag the the connector came in. Most well made BNC connectors come with the specs for stripping the cable.  It was stripped with an AMP Coax Cable Stripper. It makes all three cuts from three settings on the tool. You will find the" How To" on this tool at the end of this page.  





A:  After you've stripped the wire.  Slip the ferrule on over the insulation. Insert the center contact into your crimper and hold in place by closing the jaws slightly. Insert the center conductor of the cable and crimp the center contact.

B:  Flare the braided shield that lies between the outer jacket and the center dielectric. Insert the crimped center contact and cable into the connector body until the dielectric (The translucent teflon plastic insulator in the connector body) butts against the dielectric of the cable  (The translucent insulation around the center conductor )

Make sure the braided shield is on all the way around  the diamond texture area of the connector body. Slide the ferrule forward until it butts against the shoulder area of the connector body enclosing the braided shield wire.Connector body assembly

Place the ferrule in the correct crimp anvil so that the connector body butts against the die. Note:The drawing and photo show below the position of the screws and indicator marks on the die. This will show which side the cable should come out of in relationship to the position of the connector body and ferrule.

Crimp the connector until the ratchet releases or if using a non-ratcheting crimper until the jaws are closed and you've formed a circle with a slight flat spot sticking out of both sides....You are done.

Finished RG Connector
This is a photo of the finished item. Please note the slight raised ridge area on the top of the ferrule. That is one of the two flats that were mentioned above as a marker of a completed crimp.



Coaxial Cable Stripper Tool: Or how to get a very clean job over and over again

Cable Strip Tool

This is a BNC type cable stripper. It comes with a variety of jaws and a set of adjustable cutters.

Open Tool

The cutters are mounted in the red area in the photo on the right. There four of them and they can be repositioned when one cutter becomes dull.

 

Tool With Wire Inserted

In this photo you can see the cutter adjustment set screws. Plus the tool is closed on a RG 58 cable ready to cut for a clean strip.

Tool

The circular hole in the tool is where you will find the indicator numbers that allow you to set the depth of each pass by sliding the cover either forward or backwards. In the case of RG 58 it is 1-which is the setting that cuts through the jacket, the braid and the center dielectric to expose the center conductor -you'll have to do 5 complete turns to make the cut. 2- you reposition the wire the specified distance back from your first cut. Set your blade indicator to 2 close the tool and spin it 5 times again. 3- Is the next setting for your cutters. Open the tool. Reposition the wire the specified distance again. Set your indicator to 3. Close the tool and spin it again 5 times. Pull on the cable and all you cut should slide off. Open the tool and empty the contents.

Finished Cable
This is what you end up with this.  A very nice clean non-frayed coax ready for the connector to be crimped on.
