Sprat & Winkle coupling jig

Carrying on from the S&W couplings saga and
 seeing that i have a crap load of them to make i thought it might be a good idea to make up some sort of jig.

scratching one's head, mind the splinters.
Here's one i made earlier.
(No Fairy Liquid bottles or sticky back plastic were used in the making of this jig)

Take a piece of Ply

First off an overall view of my very handy little jig
Sprat & Winkle coupling jig

Bottom righthand corner is a piece of nickel silver strip 3mmx1mm for winding the soft brass wire for the links. To the right is the 20 degree angle for setting the angle of the coupling 
(coupling facing upwards)

Wrap wire around the pins for setting the buffer wire and the coupling carrier wire

Place in jig for soldering the buffer wire on.
I soldered the carrier staple in before i removed the base plate from the etch, also a good time to tin the base plate ready for the buffer wire at this point 

So, there you have it.
not difficult but a very handy tool. Should you need to come back at a later date to make some more you know they will be compatible to the ones you already have
