This site is no substitute for a formal apprenticeshipThis site is not a substitute for a professional apprenticeship with a licensed tattoo studio. Nor is this site a definitive source for learning the art or trade of tattooing. An apprenticeship is the ONLY universally accepted way to learn proper safety practices and sound technique.
While we welcome members of all levels, we STRONGLY advocate staying away from skin until you've received formal training from someone who works in the field. Hell, even hair stylists must complete over a year of courses, pass a state health board exam, and apprentice under a professional studio before earning a chair.
The trade of tattooing has a rich history and traditions that have been passed down from generation to generation. If you respect the art, please show your respects by learning the right way.

Spring Issue |

Just wanted to post this to see if i could learn anything about the whys and hows on springs breaking, its not rocket science but i could be missing something that could cause this.
i was redoing a tribal piece for a my brother as it was quite faded, half way through i noticed that the 7Mag m1 was snagging his skin, i did check the mag with a loupe before hand so i knew there were no bent needles, none the less i changed out the mag for a new one and still the same thing.......... as i was wondering why this was happening , all my tuning aspects were spot on , i stuck my thumb on the grommet to see how it was hittting and bang she threw the towl in and the back spring cracked in half....happy days ! its a forgiven shader , it has run perfectly in the past ..no issues what i did notice is that the spring shelf (frame) is not perfectly straight and the same with my liner, ( both the frames i think are from the same cast) and that the crack or rather the break is the exact same curvature of the non stright part of the spring deck. im not doubting Forgiven at all, but some things do go wrong some of the time and if its a user or fabrication issue i would like to know the fix or ways to avoid the problem in the future A: could this be purely a casting issue and the slightly off angle will always put stress on the spring ? b: could it be a bad batch of springs ? c: could this be user related and i have done something in error causing this to break ? i know i can just change the back sping for a new one ( which are on the way ) and forget about the fiasco.....but i would like to gain a little insight into springs and what can cause stress etc.. Cracked spring  Shelf Angle  Aligned back spring to deck ( see the same curvature match)  -------------------- NEELE PAS !

QUOTE (Teo @ Oct 31 2009, 09:18 PM)  Aligned back spring to deck ( see the same curvature match) Did the armature bar ever line up on that machine? If that is exactly where the spring was situated when it snapped, it certainly looks like it's on a hell of an angle? EDIT : After closer inspection of your pics, the spring was on backwards anyway.

Is this the ugly head of the bad metal spring batch recently infecting the US rearing its head again?If so,there have been reports that Eikon have had it too.....
....soooo,maybe as a first step,pro tem,until someone who knows what they are talking about (ie not me) weighs in,try a euro or UK spring like Wildangel...see if the problem goes away -------------------- GENTLEMAN LOSER -- INTERNATIONAL SLUM DOG -- ON A FARM

i think the broken bit moved ever so slightly when taking a picture, thus looking like its at an angle.......if you look at the second pic showing the deck ang you can see its not straight ...not by a long shot....
The Abar did line up on the machine, i have a jig and alighn tool so thats not the issue here....rather the stress being put on the back spring as confirmed by another member on here via pm , my initial thoughts seem correct....that the stress is being caused by an uneven deck.... it seems i am going to have to file both frames down to get an even spring deck......  ......i will get in touch with forgiven and see what he thinks .... seems a bloody shame if i do have to file them down..i paid quite a pretty penny for them !! but if anyone has any other thoughts or sugesstions please post them , any and all thoughts are much apreciated... -------------------- NEELE PAS !

I sometimes turn the spring around and use the longer to-the-front. That way I can make support bends(risers) up front eliminating the need for a cockring.
........with Eldubys on the alignment... it seems possible that your armbar may have veered off a tad...therefore snapping the spring....especially if that's a long stroker. 2cents -------------------- If you ain't livin' on the edge, you're takin' up too much space.

 That's only a real quick assessment, but it looks bent to me. I would say get the file out and fix it. Not the first time something like this has happened though. I seem to recall another machine that had at least 6 fatal flaws in it from delivery. And I can 2 in this machine just from that photo.

At the moment I have plenty of o'rings so none of my current set-ups are like that or I'd get a pic 4 ya. ...not sure if I understand but... what I was describing above wouldn't be a "fix" for ya or anything. ...It is a slight upward bend in the forward tabs of the rear spring...just an old manuver if you don't have an o'ring/don't like an o'ring but want to tighten up your flim-flam. On some spring types...ya gotta turn the rear spring around backwards(shallow tabs to rear) to be able to make the bends(have egnough tab TO bend so-to-speak)... I thought that maybe why(in your photo)...the spring is backwards(shallow tabs to rear) but looking back at your photos I don't see any bends in the spring. At any rate... hope ya gett'er lined out. -------------------- If you ain't livin' on the edge, you're takin' up too much space.
