I got my stigma beast with 10 watt motor yesterday from killer ink.Have used it the last 2 days for lining and its been great have been running it at around 6 and a bit volts and with 3's and 5's(that's all I've used with it so far) it shows no signs of hanging up or bogging down.The needle screw system seems to work really well and I haven't experienced any problems with needle bar loops not fitting as yet.The only worry I have is that my instruction leaflet doesn't clearly point out where to lube the machine it says to refer to the diagram but then there are no arrows.anyone?
