Color packer: a-bar does not line flat with the two coils

I have two color packers made by two different builders (who are also known artists which i wont mention). the 1st machine is yolked but the 2nd isnt.
both machines when the a-bars are pushed down it should sit flat on the two coils but i noticed that both coils on both machines are 1mm lower so the a-bar touches the front coil only, leaving a gap on the rear coil. the a-bars on my liners and shaders built with same builders sit flat on the two coils.
is this how color packers are setup? not that im having a problem tuning them but its best to learn something.

the rule of thumb is: flat on the front coil and a sheet of paper up to a business card gap on the back coil. you only want the a-bar to hit the front coil.

pls correct me if i'm wrong or if i'm right but for a different reason.

The a bar is only supposed to hit the front coil. It should hit flat, and the front coil is almost always shimmed very slightly to raise it just higher than the rear coil. If your liner machines are indeed hitting the front and rear, something is wrong. You may just not be noticing the slight gap in the liners, because of the shorter stroke. Color packers have a much longer stroke, so you will notice the gap a little more. Take a thin piece of paper and run it across the top of your rear coil, then depress the abar. If it can be pulled free with out catching, you have a proper gap. A larger gap on the rear coil is ok, it just wont hit as hard.

Hey bro.

When you Armature bar is flat on the front coil, rear coil should have between 0.010 - 0.012 T, The smaller the gap, the more power there will be, however, be careful of very small gaps. The armature bar can hit the rear coil when the machine is running even if you don't see it when you push it down by hand. This will cause some rattle and deflection of the armature bar and cause the bar to bounce off the rear coil and hit the front coil incorrectly..if you have a noticeable gap on the rear coil, it will not have as much power and may not hit as hard as your machines with smaller gap, assuming both machines are of similar construction...
push the A bar down on the front coil and check the rear coil for dust , lint ect.. this can cause your machine to deflect and rattle, be sure to keep this area clean....

hope that helps, take care..

i learned to keep the gap of the rear coil down to a folded cigarette rolling paper and fortunately i'm a smoker exclusively rolling my own fags :o) - so i can control that at every time on earth directly on the spot- not only for power reasons but also because in the first place: this will keep down heating up the coils. i also learned that as long as the front spring is roughly at about the same strength or the back one is not too thin, the a-bar won't hit the back coil with this adjustment. it is also a fact, that you should keep both spring roughly about the same strenght, means not more than one step difference- if more then at least the front one thinner than the back one- to prevent back bending of the rear spring and unitentional contact of the a-bar with the rear coil. back bending of the rear spring also causes extreme wear of it and thus it will break way earlier than normal. normally the latter will always happen in the middle of a big tattoo...

guys thanks so much for the infos!
the gap on the rear coil and a-bar when pushed down is paper thin sorry i was not being specific. i had the whole week to mess around with my machines but nothing wrong with the packers they put color in like butter :) however, i did add very thin washers to slightly lift the coils and set it up to my liking.
