Tuning RAW HM1000X and Huma 1174 adjustable regulator problems

I am working on getting a gauge for the port now. I am not going to change anything until I know what the gun is set at currently

I just noticed noticed the huma air website said hm1000 without the X . For the regulator tester. And the shipping is 34 euros !

Huma does not make a regulator tester for the RAW HM1000x. There is a fairly easy workaround, I replaced the RAW air pressure gauge which for many reads about 50 or 60 psi high (I think they are junk gauges) and replaced it with a Sekhmet 25mm Digital Mini Pressure Gauge and compared it with the Huma Digital pressure gauge screwed into the block. This way I know what the variance between the two gauges are, in my case 1.4 BAR, so not much.
At the range I have a direct air connection to the gun without an on weapon regulator. Air pressure is controlled by an external dual air regulator connected to my external carbon fiber air tank. Once a tune is found I note the air pressure reading from both gauges and insert the regulator into the gun and adjusting the HUMA adjustable regulator until it matched the air pressure gauge screwed into the action. This should be extremely close and you can adjust the hammer spring adjustment to match the velocity when connected to the external air supply.
Trying to adjust a regulator in the rifle is beyond tedious on a RAW. This way makes it ok.

So that huma air 65mm digital gauge will screw directly into the bottom of the action? Or are you using a threaded adapter?

It needs an adapter, you can contact Huma and ask them for the part number. The flat washer is needed too, so get that part number as well.

Also what adapters did you buy to bypass the in rifle regulator and connect directly to the rifle with no tank using external regulator for ease of tuning. Thank you very much fir your help, this will make tuning so much easier

Correction.
I have the HUMA adjustable regulator in the gun with it set at 190 bar, well above where I anticipate needing to go. Then the tethering adapters connecting my external 97 cubic foot tank with a dual regulator is used to tune at varying pressures and spring tensions.
Write to Marc at Team Huma-Air (techsupport@huma-air.com) and ask about the parts and seals you'll need. Tell him you are trying to do a setup similar to Bruce and his emails around January 18, 2024 with the subject line "I bought the wrong adapter for RAW HM1000x"
I think you'll need the following parts:
Regarding the direct tethering. I think you will have a hard time finding a adapter that is a direct fit. The threads of the RAW action block are ¾”-16UNF. You may find a useable hydraulic coupling at Parker hydraulics or Walterscheid.
But what you could do is turn up the reg pressure of the HuMa RAW reg up above the set pressure of external regulator so it will pass the air without regulating. Then you can add these parts:
https://huma-air.com/1-8-bsp-male-to-1-4-bsp-male-adaptor/
https://huma-air.com/rubber-steel-washer-g1-8-bonded-seal/
https://huma-air.com/foster-male-to-g1-8-bsp-female-adaptor/
Add a fat o-ring between the G1/8-G1/4 male male coupling and the regulator to seal it.
The only thing left I need to know is what the threads are in the bottom blanking plug so I can read my regulator pressure.

I don't have time to confirm which HUMA adapter, but if you ask HUMA they will tell you or sell you the adapter. Don't forget the proper seal.

I can permanently attach a good digital gauge at the bottom of RAW block through the stock to know the reg pressure all the time like FX Impact. To me it's great ti know the bottle pressure and regulator pressure all the time without any big gauges.

Ok I just got all my bits and parts....removed my rifle from its chassis.....AND NO BLANKING PLUG! DAMN IT!!!! Now I have to figure how to test my regulator set point!
Now I need to find someone to open the threads of my Rapid regulator tester so I can actually test something.
