So it's time to send you our CP direct ASA's?

I'll get it posted on my website this weekend.

The hard part is done so I should be able to knock out all the parts then move right to the next project.

Pump Kits

I'm easily scheduled 7 projects deep but unfortunately pump kits haven't made the list yet.

The initial testing on the P90 lpr looks good. I'm going to disassemble the reg and re-mic everything to double check the specs, then do more testing, then I'll gear up for production. The hard part is done so I should be able to knock out all the parts then move right to the next project.

This is where i have problems. Why isn't this prototype out in the world, or even having a few case put to it, in real world situations? Sure, the numbers can be right, and your machining could be accurate, but without thoroughly testing something, even having real world figures, you are loosing valuable effort to prove the design. A car maker doesn't think that a new vehicle will work just because they made a few million before hand.

I would gladly put this to the test, since i am surely the most unbiased person here. But that would never happen. Just because it is simple, and the math is right, fits in this frame and you shot it few times does not prove that their aren't potential problems.

I've got the testing covered, thanks.

I keep hoping that if I ask enough the answer will eventually be yes.

Lol, I know. It is on the to do list, just not in the ranking yet.

So did British Aerospace with the Comet, Ford with the Corvair, google with google glasses, Apple with the Lisa, just to name a few.

But seriously, you can nor will never find fault with anything you may make, because you are biased. That is not the best way to do husiness. Again, after all, anything i do say, like this is constructive criticism for the betterment of you and your products.

If you ever do, take a long look at how AGD did theirs with the non circular pump shaft. Pretty well eliminates any wobble and (IMO) looks much better than having 3 rods running out the front.

I appreciate your concern, thanks.

So I just finished up another round of testing today, here are the numbers.

*67 minute mechanical test (ran on my knee mill)
*Spindle speed is 660 rpm
*Two paddles on the actuator converts to 1320 rpms
*1320 rpms equal 22 cycles per second
*67 minute test time equals 88,440 cycles or 44.22 cases of paint. (I actually ran in excess of 90K off the clock)
*LPR set at about 58 psi input
*LPR running test is 58-52 psi (-6 psi deviation which is tighter than my FG-LPR)

I found zero leaks or hiccups with the LPR, the only issue was with the Fabco MSV2. I had to stop 23 minutes in to oil the valve, a few shots of oil and we were back in business.

Next step is to disassemble and inspect, then move on to the 3rd round of testing.

Here's a short clip of the test>

I have a feeling that the post above is for my benefit

But, only 58psi input? Isn't the job of the LPR to take bottle pressure down to usable or working preasure or is that a typo? Cause the way i understand it, that people will be putting 800psi+ into the LPR and no one wants a failure of over pressurizing their setup, wbether it's the intial gas up or hapfway through the day.

[luke]

58 psi is what the LPR is putting out at a stand still, not input pressure. The pressure gauge between the LPR and the MSV2 is to measure the output air of the regulator not the in coming air. The 58-52 psi shows the recovery rate at 22 cycles per second. 60 psi is typically the highest pressure people run the pneumag setups, I setup the T-Rex about 40 psi. (Lower pressures are faster)

Yes it easily handles all input pressures required by Automag builds.

Yes the post was for you but not the testing itself.

Luke, this is awesome stuff!
