If it makes you feel any better, I've still not managed to use those coil jigs properly - I just use the cores to wrap the wire round manually, I find it easier!

another way would be to keep the used coil intact and see which jig pce fits it snug. just slide the coil over the end to size it. but u don't want it a loose fit, more like just a tad tight without bending the coil rings
