tattoo machine settings

hello..taz an j...u both seem likie very nice guys i have been messing around with cheaper tattoo machines ...changing the springs..adjusting...basicially tryin to see how it all works.. I have veiwed sites and had the break down of how to fine tune your machine , but maybe either of u guys can simplify it even more for someone like me :).... I did practice on skins..but pretty much jumped into starting one on myself to learn...its not bad..but im hoping i get to learning alittle quicker than im at now ive stopped at this point...due to small like blisters forming..ive been told due to sum allergic reaction..but any feed back.. tips..suggestions from anyone would be much appreciated..thank u for your time...B
