Tac 1 chopping paint

[Mongoose]

I was using fresh paint in a vl eyeforce loader. Also I keep the marker well oiled, if not too oiled. I also shoot the excess oil with the barrell off. I am only able to fire the gun with no problems using single shot. Things start messing up when I try to rapid fire. The paint chops like crazy. Sometimes the bolt won't reset but thats on;y when I gently press and the trigger to try and walk it or whatever. What is the difference between "short stroking" and "walking the trigger"? I have to fully depress the trigger when I fire or sometimes the trigger will go dead and the bolt sounds like its recharging with air then It will fire again.

walking is when you fire the marker with both fingers alternating. if you try that with most mechs your gonna short stroke..and thats not good and might be why your breaking paint.
you have to allow the trigger to come all the way back before you shoot again...i think this may be your problem...your trying to shoot too fast

Now what Im comprehending with the springs is that I have to find the right spring for MY gun. ...It this correct?

Not exactly, you have to find the right spring for the velocity that you want to shoot at.
The short spring is for lower velocities (~250-~270).
The middle spring is for medium velocities (~265-~285).
The long spring is for higher velocities (~280-~300).

The technical:

Inside the bolt is is a piston with a fixed cross sectional area that interfaces with the carrier o-ring. This piston is acted upon by the pressure of air in the dump chamber. Since a mag's velocity is directly enacted upon by the pressure in the dump chamber, a higher velocity means that there is a higher pressure residing inside the dump chamber. Pressure is measured in (in the USA at least) P.S.I. which stands for Pounds per Square Inch. Since the bolt's piston has a fixed area (Square Inches), an increased velocity setting (Pressure) will push the bolt forward with more force, which might break the paintball. A longer bolt spring provides a greater counter-force to the pressure on the bolt's piston causing it to hit the paintball softer, allowing the LVL 10 to vent before it chops the ball, letting the bolt return rearward, allowing the paintball to drop into the breach. At lower velocities (dump chamber pressures), a longer bolt spring causes too much impedence on the bolt, allowing the LVL 10 to vent to the outside (past that little step in the bolt piston) before the bolt's step travels forward enough to seal the chamber causing the bolt to travel forward enough to vent the full contents of the dump chamber, launching the paintball at full velocity. Yes, Tom Kaye is a genius and deserves the praises we extol upon him.

Add a shim.

I must say this was an excellent post and helped me with my Tac.
Thanks

"Once you get the largest carrier that does not leak, your carrier is fine.
If you are still breaking paint at the correct velocity, use a longer mainspring because the bolt is hitting the ball too hard and needs the additional resistance of a longer mainspring.


Follow these steps in order.
1. Break in carrier o-ring with 1000 shots.
2. Move broken-in white o-ring to largest carrier that does not leak.
3. If bolt sticks on squeegy test, add shims until it resets reliably.
4. Chrono marker to field speed. (this is important, don't just do it by sound)
5. If gun breaks paint (test with no loader and make an electrical tape string for paintball to hang only halfway in breach) use a longer mainspring (on the contrary, if bolt continuously "LVL 10's" or "chuffs" use a shorter mainspring).
6. Profit.

How fast can I expect to shoot? I bought this gun to rival my friends electronic markers without spending thousands of dolllars. How fast is too fast? Is is possible to walk a tac-1? Maybe I'm expecting too much from my marker.

when tuned.....it will outshoot you!!!! you cant peak that gun.
if you really wanna shoot fast you need to pnuemag it! and it isnt much of an upgrade $$ wise

[stompdown]

Pneumag huh? Greeeaat, more stuff I don't understand. Ah well, thanks for the great advice now I'm going to go research pneumag stuff.

[stompdown]

Thanks for all the great tuning advice it was really helpful. I have one more question. I have the ule trigger but I don't quite understand the purpose of it or the purpose of adding shims. Please explain? Thanks in advance

the more shims the lighter the pull

when i tune mine..i add as many shims as i can before it goes full auto or doesnt slide into the body.
when tuned right they can be "walkable"

Sniff... now that brought a tear to my eye. Why can't all newer members be like you? Most of them are like, "Search button? What's that? Why can't you just spend thirty minutes of your time and write up a post explaining to me what I want to know?"

I think you're going to fit in well here.

[Tunaman]

i try to tune my markers with the middle spring...the gold one
are you walking this marker or just single finger? waht kind of hopper are you using?
also have you oiled up everything while changing things up???

Middle spring is RED!

[Mongoose]

Middle spring is RED!

opps...i cant argue this man!!!

[Danterwhoo]

When you use the middle spring ( the cut one) which way does the cut end of the spring face??? Toward the barrel or to the rear??

level ten tuning video

Finally!!!! A video!!!! Thank you Coralis!!!!!! You are a savior I haven't been able to find that after looking for a long time.

[Coralis]

The cut end goes to the bolt ... the bolt is made of stainless and will not get messed up by the cut end of the spring. and your welcome
