I added .5 ounces to the T2 hammer weight (it takes a cocking rod) and it did NOTHING to the efficiency that was noticable with my crude measurements.

It has to be, then, the spring. Now wouldn't you love me to tell you that you just need to buy the spring for a T2 and your S6 would be more efficient.... um no.


I dropped the T2's spring into my Six and got a LOT more effiency - because the ball was going about 2 feet. Crank in the IVG - nothing. I could have run it at a different pressure to figure that out - but I was not willing to dork with it that much.

Bill, Why doesn't the T2's spring work in the S6?

I am finding this to be hella fun! Even though I have no real answers yet - and it doesn't really matter in the long run.

Well,technicaly speaking the diameter of the Moon divided by the pi of the Sun in an equilateral distance of the magnetic poles.
Hell I don't know I'm just a machinist. More Pixe Dust.

I don't have to know science to boil water Or in this case,I don't have to
know pneumatics to make a paintball gun. And you guys thought we new everything.

It went like this. Rod,I can't find a spring the same length and strength.This one is a 1/2" shorter. Rod says,well buy a few and less try them.
Pretty scientific huh.

Actually we had everything under control. Calculated to the 5th place and drilled the hole in the right spot. After all machining IS putting the hole in the right place.

Bill,

So - the bottom tube length is the same - the valve holes are in the same place - the valve is the same length - the spring is just shorter?

We did align the valve more precise in the T2 then applied that measurement to the S6 also. The spring is 3 lbs force and is 2 " long.

I really believe its getting better airflow thru the bolt and we changed to a better tool to bore the reg bottom which gave us a better finish. That is the only thing I can think of that could be giving you different results.And of course we will apply this to our other guns if this is the case.

Bill - the reg makes no sense to me - once it is 300 PSI - it is 300 PSI - you have that chamber at that pressure no matter the reg.

The bolt makes sense.

The hammer weight makes sense though too - but that was proven to be mistaken by today's testing.

TF, just to make sure it's not the reg, why don't you put the S6 reg onto the T2 and test again?

The T2 spring is noticeably shorter. I had my T2 apart to adjust it's timing and the spring was definitely shorter then the spring from a WGP tune-up kit that was on the workbench at the shop I was at. I didn't take measurements, but I'd guesstimate it was at least a good 1/4" or more shorter then the Sniper spring.


-------------------


I also had a small hiccup with the removal of the pin/bolt. The pin was not extracting very easily. 4 people tried unsuccessfully to remove the pin by hand. In the end a vice and handtools were necessary to dislodge it.

At first we thought maybe grease had been applied to the bolt (delrin), but that was not the case. We think maybe that the o-ring is turning over on itself and binding with the pin.

I used the T2 reg for both and found no difference - I don't think switching them would produce anything.

Actual tested numbers in playing situation.
First run T2 (I don't think it has the production spring in it, look like a modified S6 spring).
Reg set at 2.5 turns in. IVG flush with the back cap to get the velocity to 250 fps (field limit)
CCM barrel with the correct sizer for paint.
Pretty good consistent (size/shape) paint, call it a 8/10.
Temp 28*C, humidity in the 90% 's.
13ci/3k tank with Assault reg at 650psi output.

First fill: 2500psi after cool down: 150 shots gauge read 1000psi. 10 psi/shot
Second fill: 2800psi after cool down (got them to slow fill): 230 shots gauge read 800 psi. 8.7 psi/shot
Third fill: 2300psi after cool down: 200 shots gauge reads 500psi. 9psi/shot

I was happy with what I was getting from my 13ci tank though I usually run with a 45/45k for convenience sake.
I will be tuning this marker this week, and will try to redo this to even better numbers.
