RAW HM1000 was leaking. I installed new seals today and put the action back in the stock. Charged to 3,000 psi and all seemed good.

Loaded pellet, pulled trigger and nothing. The hammer went forward and hit the valve but no air release. Valve sounded soft, not bound.

Went to remove the bottle and the block with the reg easily spun in the block. So the reg never pressurized. Trouble now is I can not remove the bottle and the stock wraps around the bottle so can not remove the action. What are my options? Drill bit in the foster and tap with hammer? Can I unscrew the gauge until it vents? Tank has 3k in it and trying not to die.

I have an email off to Martin.


Next question. What did I do wrong on the reseal. All I did was take old seals out and put new ones in.

I hope someone else who is familiar with the Raw HM1000 will reply with some better help.. first off I'm very scared of unscrewing anything pressurized..I have a hard time mentally unscrewing the air tubes off my hatsan velox pistol and that's what you are supposed to do to swap air tubes for a second filling..
now I have read of several guns that don't have degassing screws,I think they all should have them.. anyway you didn't mention if it has a degassing screw but if it does that's the first thing you should try.. second thing you could do is loosen the gauge.. not a long way because 3000 psi you don't want it to peel off the threads and go flying.. so like aea guns don't have a degassing screw and if it breaks so you can't fire until empty, they have you loosen the gauge.. myself I'd just loosen up maybe a turn, since you don't want to die, I don't see any issues with loosing it and letting it leak out over night.. slow is much better than flying off..
don't put a drill bit in the foster fitting and hit with a hammer..I'd expect that to be a good way to shoot the drill bit out through something.. sounds like a quick way to get hurt..
now as to what you possibly might have done wrong.. I don't know if it's regulated but if it is and you changed o rings in the regulator, or for that matter worked on the regulator,id suspect that you possibly left the regulator adjustment open so it is not giving you any pressure..
another possibility is something, like even a piece of a o ring got in the air passage and it is possible that could be blocking the air.. but I would think it would at least make a little puff of air when fired..
I'd like to help you more if I can.. you are welcome to PM me..

If the vblock was under pressure it just a it easier but "I" would just hold or find the proper material to keep the vblock from biting the wood and unscrew the bottle. I it was all pressurized it just makes a loud pop as unscrewing,should be nothing to fear except damaging the stock.
Or I missed something (which I do these days).
Keep us posted.

First thing I would do if remove the stock. Single bolt from the bottom. Your appears to be newer and should come right off. Some of the older stocks didn’t come off without removing the bottle.

I suspect you didn’t tight the reg body into the action. It needs go be tight enough so that it stays in place as u remove the bottle.

Worst you may have some thread galling going on between the bottle and reg, very common on these stainless thread. But considering you only removed it once, doubtful. In the future if good to use nickle bases any seize on the threads between the bottle and reg.

Thanks guys.

Action will NOT come out of the stock with the bottle in place. The front of the stock curves around the bottle.

If I go with a pinch in the foster to pop the check valve I would have it locked in the biggest vice grips I have.

Just checked and gauge is still showing same pressure as last night. I guess I could just wait the ten or so years for the seal to perish.😂

You would effectively be removing the reg from the actions under pressure.
But maybe this could be done slowly till it develops an air bleed

I have an email out to Martin. Hopefully he can point me in the right direction. The gauge can be backed off but I’m not sure what style they use. I may be wrong but doesn’t the Brit style have an oring and the American style not?

For sure learned one thing. When working on a RAW test it before putting in back in the stock. 🥴

This would save the day right now.

Is there any chance that the reg isn't sealing, and that the plenum has the full air pressure? If so, you may not have enough HS tension to crack the valve open. You could try adding more HS tension to see if this is the case, but if there is NO pressure in the plenum, you may risk damaging the valve.

I think this is what I would try first. If this didn't work, I wold probably crack open the foster fill fitting until a very slow leak developed. After the leak stops, There would likely still be pressure. I would very slowly repeat this process until all the pressure has leaked out. This is what I would do, it is NOT what I am recommending anyone else try. We don't want anyone ending up on Ridiculousness! ;)

I don’t think pressure is getting past the reg to the valve. If you watch the video you can see the reg portion easily turns in the block which means no pressure.

I’m in no hurry, it will just be set aside until Martin gets back to me. Worst case I ship it to him.

That tool I posted above would solve this quick. 😁

Wild, my V-Block turns easily with a full charge of air FYI 👍 and, I am glad you are waiting for his response!

I guess it's normal. I just checked mine as well...it moves.
That said
Turn bottle to left..maybe put a foam or leather belt to keep from marking stock with the fitting while turning.
Turning the bottle under pressure will be hard. I used a leather belt around the bottle for a better grip
You will hear a loud pop that will scare the heck out of you..it's normal. After the pop, the bottle will be easier to turn.
I have done this..not dangerous, but the first time you hear that pop can make you change your shorts because you think you broke something. You didn't.

The v block turning seems correct to be. It is gliding on the two orings.

The regulator portion is necked up so I couldn’t unscrew it as is even it I tried because the v block would end up against the front of the stock.

For sure a first world problem. On the table next to it right now is a Datstate Pulsar, USFT, a P70 and a BSA Goldsrar SE. life is good. 😁

Correct. I just don’t want to mark up the pretty stock. I have a few old BSA SuperTENs that before AZ go ahold of you had to remove the buddy bottle to refill. Man those orings took a beating.

I would GENTLy loosen the gauge til it just barely leaks and let the rifle sit for a while. I've done it a lot and no problem. Doesn't take much loosening at all, and I've been advised on other guns to do this to get around just such a situation. As always, ymmv.

Is there an oring under the top of the gauge? This was my first thought but wasn’t sure if the oring is at the top or bottom.
