just spent my evening taking apart all the end feed fitting that i have been practising my soldering on, and all of them were soldered correctly even the 28mm straight couplers,, they just looked rough. also ive seen on a few vids on u tube people wearing gloves to remove the solder runs,, while the solder is wet, i this a good idea or not. also can the fitting be re used to practise on, do i have to file all the solder out of em. thanks men
