when you screw the pot on you only want the bare cable sheath to just be level with the top of the threads inside the pot, I always pull the cores with a pair of pliers before adding compound and blow out the powder so the pot is clean and dust free. When you get a crimper which hopefully will be early next week you need to ensure the gland slides back away from the pot so you can really get arount the whole pot to crimp it up tight, apart from a couple of basic mistakes your attempt looks good, it is straight and the cores look in good condition, practice makes perfect :rockon:
