LPR integrated into forgrip

[renie]

forgot you guys work imperial :) my pistons gonna be about 0.325 od :) so alot smaller than u think Hill :)

So maybe lengthen the piston between the orings to keep it from wobbling as much? Also further dish out the end to cup and holt the pin more?

Probably not, just keep an eye on the alignment. Even though the HVAC schraders are rated for high pressure, it's more of an on/off service design instead of regulation. I would just be sure and test it before I hung an SMC070 off of it.

I tried two other different cores in that Next LPR and they all failed shortly after working initially. The superbolt LPR is another reg like that. That's why I distrust them all now.

Hmm...an LPR made like a ULT would be $wanky. Kind of a miniature angel LPR.

Thats smart. I had the one in the pictures above running at high rates of fire for around 20k rounds before the valve died. But it was 10 years old and a low pressure valve as well. all that would be needed to test it is an air supply and a full auto board and let it go until failure. Time it and do the math at the rate of fire to see how many rounds they handle. I could do it or renie could but he would need 900 psi input pressure to get accurate results. Its a long way but if he makes two of them and and sends me one, we both test it and that would provide better results. If the valve is not capable of this job we can go from there. But they are so cheap to buy and small, it would be great if we could find one that would hold up.

Also when my lpr went out the marker went full auto for three shots then the line blew off the noid. The noid is still fine and works like normal. Probably lucky though.

That would be great.

For the most part he is just wants to make a new housing and use parts from a proven regulator.

I hadn't really paid too much attention to the details above but this clears things up a bit.

Since this is the case, use the Micro Rock internals/design instead. Especially given the SMC noid's limit of 72psi, use something that will be the most consistent at lower pressures.

[renie]

this is just a prototype but it will ne to be about 1/2" longer as the spring needs to be a bit longer and i want to increase the piston length also i need a short grub screw not a 1" one :)
the leftside(top) is tapped npt but it would work better being a male thread i done it like that so i could whackmacro straight in for testing :)
will try and get some air through it over the weekend :)

Nice. Is the brass insert threaded or loctite'd?

***

You may need to square off that spring end, especially with one o-ring on the piston.

[hill160881]

Its small like we need
You may want to extend that piston and add another oring. We only need the schrader valve that will be used for the next version and testing can comence

its threaded and loctited, its a temporary design whislt i await my tap for the schrader valve :)
the spring will be square on the final design this is mearly for test purposes :)

I cant wait to see the results

The only problem is that leaves you getting a 40 dollar reg to make thit all work and the internals we are looking at are about 1/4 that cost.

I agree totally but think these valves are worth a try at the least.

Also I run all my mini smc noids at 80-85 psi. They usually start to leak at around 100 psi

True, Micro Rocks aren't cheap, but you get what you pay for.
As for the smc noids, the manufacturer rates them at a max operating pressure of 72psi. Sure, you may be able to squeeze out 10+psi more, but that doesn't necessarily mean that you should.

Not trying to derail the thread or anything, just offering some constructive criticism.

[renie]

well its together and works so far so good :)a little sticking on the piston o-ring where the bores a bit tight so i'm going to open up the bore a little that should be ready for some proper testing :)

[OPBN]

Has anyone considered the possibility of having a dual reg? One side 200-600psi and the other LP?

[hill160881]

The thought of that makes my brain hurt.

It would be possible though.

I hope you guys come up with something that works, I need a small consistent internal lpr for my G-Force frame......all the small lprs I have used seem to blow hoses. As soon as I switched to a foregrip mounted rock lpr like pictured above, things were much better.
