Hi, I was just wondering something.. when adjusting an A1's pressures (mini reg and LPR) you have to adjust the mini reg pressure by adjusting the velocity screw on the reg handle..now... if you have to leave the screw set at that pressure, how are you supossed to adjust the velocity? I hope you all understand what I'm talking about.

How to correctly set up pressures?
Wherever adjustments may be required it is important to have all pressures set correctly. To do this, first set the in-line reg out-put to 270psi using the exhaust valve pressure gauge (see pic 1). Adjust pressure output up or down using the velocity adjuster screw until an output of 270psi is indicated on the gauge.

Once the in line reg has been set the LPR can be adjusted. The LPR is located in the rear of the gun on the left tube (as marker is pointing away from you). To disassemble correctly see manual. To achieve the correct pressure one must add/remove shims to increase/decrease the pressure and verifying the correct pressure of 57-60psi has been achieved using the LPR pressure test gauge (see pic below) and is covered in detail in your Angel 1 owners maniual P.24.


Pulled this outta the FAQ thread that you can find here:

Adjusting the mini reg to 270 will allow you to correctly "set" your LPR. If you need to increase your velocity after you have set your pressures, just adjust your mini-reg accordingly.

You set the mini-reg for 270 using the velocity screw and then the lpr for 57, this is more to setup the operating pressure or another way opf looking at it is as balancing them, once those are set you make velocity adjustments using the the velocity screw again. The lpr pressure will change slightly as you adjust the velocity but this is ok. For an example, to run at 280fps I have my mini-reg set at 240psi, my lpr shows ~56psi almost 57psi (at 270psi on the mini-reg I am pretty close to 58psi on the LPR). So you can see that adjusting the mini-reg has some effect on the LPR pressure but not very much. Hope that helps.

so do I have to reset the LPR settings everytime I adjust the velocity?

no, just set your hpr, then your lpr, the adjust the hpr to the preferd vlocity.

So once i set both pressure to Joy settings and adjust my velocity..i dont have to worry about resetting the pressures again?

MSV1,

I take it that you check your HPR after you chrono? What HPR does the A1 come from the factory/store? If it comes below what the manual states then extra springs are included? If not, why should you have to buy them when they should be included?

Bleda,

Wouldn't you have to check your HPR if you get a new tank, right?

no, once the lpr is set with the mini reg set to 270 it is set for life, thats why you need to make sure your mini-reg is set to 270 so that the LPR wont matter if you change the tank on it or not.

I'm hoping I can answer your question, Yes I checked my pressures after I chrono'd...Why? because I was interested. My A1 showed up w/mini-reg @~280psi and LPR @~60psi. When I removed 1 shim the LPR dropped to 56 psi w/the mini-reg @270 psi. If you look at the stock shims vs. the shim kit you can purchase you'll notice there is a small difference in thickness. The shim kit allowed me to fine tune the LPR closer to the desired 57 psi. Hope that answers your question.

Mine did come with a couple extra shims for the LPR, they were in the tool kit. I have not heard of anyone not being able to obtain 270PSI out of the mini reg, without having tank issues or asa issues. But then again there are only 2 A1's at my field and I dont get to the forums too much.

You mean to tell me I have to buy the "tool kit" aka shim kit in order to get extra shims? Are the shims in the A1 mini reg different from the stock shims from a 05 speed?

MSV1,
Why would the shims in one kit have a different thickness than the stock kit? Did it say how much each shim is to psi? I believe the manual says each shim in the A1 mini reg is approx 2 psi.

You would have to buy the Shim kit for the LPR. The stock tool kit that came in my A1 box had 2 shims under the stack of o-rings. I would check in there if you are needing shims.

Shim Kit:

The mini-reg does not have shims in it. You only need to turn the screw in the side of it to adjust the pressure from it. Cannot upload pics from here but pg 20 in manual shows the Mini-reg, Pg 25,26 will show you the LPR.

Are the shims in the A1 mini reg different from the stock shims from a 05 speed?
I do not know if the shims are the same for the A1 as the 05 speed.

so, should I swap out the shims in the stock a1 with the shim kit on fixmyangel website? I forgot the mini doesn't have shims like the LPR. Maybe MT can tell us if the shims on 05 would be the same.

Bleda

i believe they are exactly the same diameter which is what would really matter, if you have 05 shims i would make sure they are the same diameter and if they are go ahead and use em.

so once you set the minireg and LPR to the WDP reccommended pressures, then set the velocity to an appropriate velocity..you're done? is it that simple? like a SET IT AND FORGET IT type deal?

Bleda

thats it, set it and forget it. Thats why WDP uses the shim style, it may take a few more minutes to adjust, but once its adjusted to the correct pressure your set for basically life.

DAMN! that's easy..thanks for the info Bleda

No, there is no need to do that.
