Back when I ordered parts from SPA I ordered the two spares along with other parts for my Airmax Dominator but that's been a long time and dealing direct from China takes a long time. You might try Xisico USA they might have some in stock down there in Texas

Mike M probably has some too but never inquired about them when I talked with him.

I've got a few M8 gauges here, some artemis and some 1" size generic if you are still looking.

Well I tried this trick, and it didn't work and I still have leaks.

I ran a very thin bead of Super Glue around the seam edge of the gage face,
let it set over night, filled to 500 lbs of pressure and let it set over night.

Was down to zero, when checked in the am............

So I am awaiting a new gage to arrive...............and will try again..

Don who did you order the gauge from, I would also like buying a couple of them because the one on my .25 reads way too high and I'd also like to have a spare as well. I'm sure that Mike M probably can order up gauges from Xisico direct and from the prices that I've seen in the past China parts are very inexpensive. I almost think that the accuracy of the gauge is a hit/miss luck of the draw as with probably most Chinese PCP gauges which I think are all the same size. Shipping direct from China is really expensive and when I made an order a few years back for parts for my Airmax Dominator the shipping was more than the parts because at the time the only way they'd ship was FEDEX but all things considered it was still a bargain, I bought a regulator, 2 gauges, 2 barrel sleeves(on the SPA M16 that's where the port is) and 2 magazines for about $110 shipped and I think the shipping itself was close to $60.

Wayne,
PM sent with info,

The area leaking is #17 to #21 and it sealing with parts # 20 and 23 etc.

I am attempting to see if I can make improvements, with less parts etc.

Thanks,
Don

Guys
Here comes a dumb question, as I don't know the answer, but have SWAG..............

Since, I have a leak in the gage face/plastic face edge and main body edge etc,
and the bottom of the gage stem (# 17) that seals against the rubber seal = part #21,
would increasing the psi to 3000psi provide a better seal, I have been using 1500 psi max pressure.

My swag is that it would just leak faster or more.......................

Don the way that you described the leak, the air was coming from inside of the gauge out around the lens itself and not from the threads where the gauge screws in would tell me that its going to leak no matter what. For a temporary fix until you get a new gauge you could put a burst disk or a sufficient sealing delrin washer in it first then it should seal

That's the way that I thought you meant that it was leaking was through the internals of the gauge instead of the gauge threads. The gauge wouldn't read any pressure but at least using the gauge on the pump or fill adaptor you could tell the pressure that you've put in the gun.

Nvreloader · « **Reply #509 on:** June 11, 2020, 01:14:56 PM »

Thanks Wayne

It is leaking out of the gage face and out of the #21 part area, only a single bubble every few seconds,
this is driving my crazy, just about as as bad a LL, (Leakin Lena my QB 79).

I never thought about using a M8 bolt long enough to fit, at least I could test/check every thing else out,
my gage on my SCBA tanks filler is right on the money for checking against my good accurate psi master
gage.

I can turn a plug to fit under the gage stem out of some soft nylon material, for a temp seal there,
then I can finishing checking the valve and it's seal etc.

One good thing about this leaking, when I do my 25 cal, I'll know just where to look etc...........

I'm thinking through a SSG (https://www.gatewaytoairguns.org/GTA/index.php?topic=102095.msg960287#msg960287) for my Sentry. Does anyone happen to know the thread for part #54? Or anyone that can bore that part out to allow a 8/32 sized threaded rod to slide in and out?

Nvreloader · « **Reply #511 on:** June 11, 2020, 08:11:19 PM »

David
Here is the info I found on my 705-2 Sentry, 22 cal
page # 24, Post # 477,

I have not got to the 705-9T, 25 cal yet, still attempting to stop a air leak on the 22 cal.

Power adjustment knob > 1.010" dia with M8x.125 threaded shaft .800" long, has approx 1/2" adjustment range,
for hammer spring, the plastic spring adjustment base is very sloppy/play.

Hammer > 1.040" long, 1.010" dia, weight of 746.2 grs, with a spring tunnel hole of .560" dia x .730" deep, with a hammer nose on the hammer face approx .300" long and ..300" dia,

Hammer spring is 2.460" long, .518" O/S dia, .434" I/S dia, 15 coils, .042" dia round wire.

Hammer stroke of = approximately .510"...........

Do you know which model/type of SSG you are building?

I have been thinking about one also, along with the lite weight hammer if possible,
just don't know for sure which type of SSG would be best with the hammer nose sticking out there.
I do know that the hammer nose rests on the end valve stem after firing, and can hold the valve poppet open,
I have to cock the hammer to allow filling with air, from empty and my power adjustment wheel is on 1 spot.

Here are the SSG designs so far,

Shows most all the designs types so far.

Tia,

Dead Springer · « **Reply #512 on:** June 11, 2020, 08:28:58 PM »

Thanks Don. I'm thinking the original design. I don't want to change/modify the hammer, trying to keep things simple.

Wayne... post a pic of that stock.... I can not find mine.

Here's a pic of the nice stock Scott so kindly sent me

Nvreloader · « **Reply #516 on:** June 12, 2020, 12:46:12 AM »

Nice Guys

I just wish, I could get the same stock in the plastic version for hunting etc,
A wood stock just don't look good after a trip or two...........in the pucker brush around here.

Thanks,
Don

Wayne52 · « **Reply #517 on:** June 12, 2020, 01:07:28 AM »

The thing that I like about the Sentry's stocks is a wonderful durable finish on them from the factory, I always transport my guns in a softcase behind the seat of my truck when heading for my hunting grounds and haven't had any problems nicking them up that way. That polymer fore stock on them is very tough and pretty much indestructible when resting it on about anything you can imagine. Everyone has their own preference though so I understand why people like a polymer stock for lightness and durability. Then again there's some people that think they're butt ugly but personally I like the looks of them myself, there's not another pcp that's like them. They have a super nice design and I wouldn't be a bit surprised if they were soon available regulated as well. One of the neatest things they could do with these guns is replace the steel airtube with a titanium tube, that way if they did decide to regulate them you could have much greater pressures and a much lighter gun to boot. I'm also a big fan of the valves in them too, great design that's rock solid IMO.

I am really looking hard at a reg for the 25 cal and if that goes good, I'll get one for the 22 cal.
I just don't know enough about the brand names, styles to make a valid choice, etc...........

I'll give these stocks a try, but I don't expect much, this Sagebrush eats wooden stocks,
and there is NO smooth rocks to be found, most are like saw teeth..............

as I always say, "Looks like it chased a pphart thru a keg of nails". LOL

Do you think that there is enough length to work with, using these bolts?

I am thinking about using Flat Wire springs,
I just have to figure out the poundage rating of the stock hammer spring, as I like them etc.

Thanks,
Don
