How do you bend your springs?

and what brands&gauge do you stick to and why?

Normally roll the front one and bend the back one in a vice, avoiding a sharp kink in it.
As for the guages, there are so many combinations depending what you want your machine to do. Also dependant on the machine make.

We bend ours by hand, and they're cut accordingly to the machine's we're using. We originally were buying our springs from Eikon, as they offer the best quality we found in pre-cut springs, the problem with them is they don't offer front springs for lining that can be bent, they're made for eikon specific armature bars (which suck ass btw). but they're back springs and shader front springs are great. If you cannot order from eikon i would look into buying a spring punch set, as well as the clips and the right guage spring stock.
Universally, i've noticed most everyone go to an 18 guage, as its sorta the good inbetween. but that's all personal opinion. They're are other questions that come into play as well. Such as the guage thickness like we mentioned above, then tension at which you bend your gauge, whether or not you set your a-bar with or without a O-ring. (having an o ring on your machine generally increases the tension of your front spring.)
Theres a lot of other things i could continue with, including alternative ways of bending your springs that we personally find work the best, but you also need a machine where you can adjust the bridge and your contact points. So we'll save that shit for a different thread lol.

Yeah but like... literally, how do you bend them?

Springbending for Dummies :P

Are you talking about like. at what angle are they bent at?
Cause if so, its hard to determine that because i can't really describe that via typing lol, its more or less something i have to show you. But if your interested in spending like..16 bucks you can buy an A-bar mount that keeps your a bar and springs straight while setting them up, and some will also have a guage on them which show you how far back your springs need to be pulled....so it basically just does the bend properly for you as well as gives you a perfectly straight and easy a bar set up.
Im going to try to find the one im talking about and will post a link in a few minutes lol

I'm pretty sure the one that we have kicking around here is from danny fowler, but i can't find it on his website. So here's basically the same thing.
http://www.monstersteel.com/Tattoo-Spring-Flake-Adjustment-Tool-Aluminum-nid-709636.html

Also note that we personally don't buy from this site, if im not mistaken its a scratcher site, they sent us some books and shit to look through, and its all kinda whatever crap. but i mean, if your just looking for this one tool they sell it, They also sell spring punches, and spring stock at an 18guage if im not mistaken.

bolt the front spring to a spare abar. turn it around so its in the rear spring position. holding the abar, gently push the spring against the table top into the desired bent position.

VERY IMPORTANT* when you bolt the spring, add all the fancy washers you plan to use on the finished machine, you do not want the bend under a washer.

^ what they said lol!
If you bend your spring with a washer your not going to get a bend so much as a kink, if you gotta kink your going to have a weak ass spring that doesn't bounce the way you need it to.

i personally prefer rolling them than really bending them to avoid kinda crease. for me it works best i do it the 3-finger-way without a-bar, using a thumb in the middle as counterpoint to get a round bending. with a-bar against the spring saddle it always tends a bit to a sharper crease and you have to be very careful to avoid that the "with-a-bar-method". also bending it flat around some round object like a bottle also works very fine.

you don't want a sharp crease, because the work motion is affected in a bad way and the spring will break rather sooner than later.

i forgot:

just for the back spring: in between you always have to bolt them to the a-bar ant to the machine to check tension. sometimes it takes quite a few times of bolting/unbolting, but in the end it pays. for checking the tension i prefer a cheap digital luggage scale and an old bent needle bar to hook the a-a-bar nipple to that. the weight/tension depends on what the machine is supposed to do.
you can`t take measure of the front spring's resistance/tension that way, but in my eyes you don`t need to do that. here it depends more on the factor gauge or o-ring or not. (zero-)compression adjustment is more the thing of the back spring.

I would not suggest rolling front spring at all. The fulcrum point of a rolled spring changes continually during contact. The spring needs a constant fulcrum point in order to make it run efficiently and smoothly. How can we have a transfer of energy if the fulcrum changes the whole time? I believe Having the spring rolled also stiffens the spring, which means the coils will have less time to gather energy per stroke, and the stroke will be stiff and violent. The cusioning effect of the FS is nearly important as allowing the coils extra time to magnetize. Although, Too weak of a FS and you'll bounce off the skin. Springs can be a difficult concept to understand there are so many variables in a tattoo machine it's ridiculous. If your machine is tuned correctly you should see sinusoidal wave patterns that will look like a "fluttering" or "waving" armature bar. In a fluorescent light or T.V. It'should be visible. Look up Harmonic Resonance.

i believe in avoiding a more or less sharp crease in any spring- front or back- will prevent them to wear down until breaking them much longer than with the beforesaid sharp bend/crease. in my experience rolled springs live at least twice as long as bent ones and also keep their resistance/energy much longer. to compensate stiffening resulting from rolling, i normally use thinner ones than i would use with bent ones. to keep the roll in place and shape i use them exclusively with o-rings.

i also think that the cushion effect of the front spring only exists at the upper hit point, the contact screw. cushion effect in direction downwards to coil and skin comes imho exclusively from the back spring.

i also have a few machines tuned to zero comp, what means the front spring barely hits the contact screw without any cushion effect at that point. but that tuning i get exclusively by an exact tuning/rolling of the back spring to avoid a too big/small air gap and choosing the right gauge for that. with this kind of tuning you get exactly the energy of the back spring without any corrupting influence of the front spring in form of cushin effects. there the back spring doesn't have to "fight" against the front spring and isn't affected by reverse bending by it. results in quite a bit more back spring cushion and less broken back springs- if rolled and not bent. works for me very nice for stuff like b`n`g and colour layering.

but that's just my 2 cents. as far as i can tell: works fine and without any broken spring since years.
