52 in this modification the spray tube 52 can be removed and one ora plurality of spray nozzles 62 62 39 can be provided in place of the spray tube 52 as seen in fig5 and 6 wherein the nozzles 62 62 39 are shown connected to the cylindrical shaped receiving means 50 50a which can be connected to the hub means 40 40a that are both connected to electrolyte under pressure so that the similar portions of the hub means can move liquid through the nozzles from electrolyte schematically shown in fig5 and fig6 in fig5 nozzle 62 is shown as spraying the work pieces from one end of the barrel if it is desired to have another nozzle at the opposite end ofan electrolyte source shown schematically it can be coupled with the hub member 40 39 that is essentially like hub means 40 and electrolyte can be forced therethrough to the nozzle 62 39 shown in phanton whereby electrolytecan be sprayed in the spray pattern of nozzle 62 to more completely spray the work pieces in fig6 the nozzle 62 is shown as having a 34 t 34 shaped slit 65 and a horizontal orifice 67 whereby electrolyte under pressure can be created ina vertical spray 58 across the barrel as well as horizontally in fig7 an apertural nozzle 80 is shown with randomly placed apertures 80a that can be used with or instead of the 34 t 34 shaped slits 65 or horizontal orifices 67 that are pictured in fig6 the nozzles 62 62 39 and.
