Huma regulator(s) question for Mauruder .177

[3 at 8]

I want to tune a Marauder .177 for the purpose of Hunter Field Target. When would you want to use option #1 as opposed to option #2? I understand with option #1 that your gauge would read regulated pressure. With option #2 are you not using any gauge or replacing the gauge block? I have much to learn before I do this project and am in no rush to undertake it, but want to get the regulator now because there on sale. Thank you.

Option 2 you usually still do use the original gauge block,
it rides right up against it and the face mounted oring will seal against the gauge block.
You need to remove one of the oring on the gauge block and the gauge will still only show regulated pressure.

For simplicty just order the complete reg with gauge block.
you get advantage of bigger plenum too, not that it would matter much for .177

Ok thanks, the price difference is negligible between the two, so, if no real advantage I'll just get option #1 then that you screw the pressure gauge directly into.

I have a gen 1 mrod with the option 1 reg set at 100 bar/1500 psi with a 20 gram MDS hammer in it and its shooting JSB/AA 10.34s at 890 fps for 18.5 fpe. I can shoot a full 60 shot match with over 2000 psi left in the air tube, never have actually shot to see how many it get before coming off the reg. Its shooting with an extreme spread of 6 fps and average of 3 fps per shot to shot so very consistent.

As lennyk stated if you keep the gauge block in place then either option the gauge reads reg pressure. Leaving out the gauge block will add plenum  volume but in all honesty the added volume/shot count will not ever be needed for a FT match. I like the gauge reading reg pressure so I can at least know when I am getting close to needing to refill the gun before it actually comes off the reg.

You will be happy with either way you go that's for sure.

Yup .... 80-95 regulated shots at the @ 18-19 ft-lb setting in .177 caliber is the norm doing an AFTER the FACT regulator conversions as done above ... ( NOT retrofitting a current F&T model )

There's no huge advantage between the two other than a little extra plenum volume for more power with option #1.  The thing about option #2 is that when needing to pull the reg to make adjustments (which you will when tuning), you don't have to remove the gauge and pull the gauge block.  You can just tie a string or wire to the reg's filter screw before installing it and then you can pull the reg out real quick.  You can do the same with option #1 once you remove the gauge.

The disadvantage of #2 would be that you wont have as much plenum volume as option #1 unless you go with the Hill Air aftermarket gauge block, which is bored out inside.  Replacing your stock gauge block with the Hill gauge block will give you about the same plenum volume as option #1.  For what you want to do, the Hill gauge block is really not needed.  The stock gauge block is good enough for achieving that power level regulated.  I mention this only to make you aware that there is an aftermarket gauge block that is bored out already that will increase the plenum volume over the stock gauge block when going with option #2.  It is a very well built one too, and is the route I took when regulating.  Either one of those regs are fine to go with.  Be sure and remove the depinger when installing a reg as the reg becomes the depinger.

When installing the Huma would it be possible to relocate the pressure gauge so that it reads fill pressure?
In my ignorance the gauge would need to  go before the regulator as opposed to between the reg & the valve.
My thought would be to add a Tee fitting at the fill head to handle the gauge & the 1 way foster fitting.
Will this work?

NO ... the factory air tube and location of gauge where a hole exists for the gauge cannot be moved. The only place for a regulators mechanics while providing a plenum space is UPSTREAM of the gauge.

Thanks, Motorhead
I realize you are an expert & value your input. (Sound like BS; it's not)
Let's shift to a different gun, please
The Maximus
It is possible to bypass the Maximus gauge using an Magnum Air Power gauge bypass.
In this case would the Tee idea at the fill cap be valid?

Personally No Clue ... don't work on them

Why do you want to bypass the gauge block? I modded my Maxi for a while and wound up going with Disco TP, (barrel and valve drilled to match) OEM hammer spring.  I am getting 755 fps/22.8 fpe for about thirty shots.

If you are interested in tube pressure Huma offers a part that replaces the factory fill assembly and it has a gauge.

I am installing a HUMA regulator.
If the gauge remains in its OEM location it will measure regulator pressure as opposed to fill pressure.
Relocating the gauge to the fill side of the regulator would allow measuring fill pressure (I think)
This would require bypassing the gauge block at the OEM position.

As mentioned,  my idea is to relocate the gauge to the fill valve position using TEE (Rocket science??)

What pellet weight got you the string you mentioned?

[mobilehomer]

Squirrel, I forgot to mention. JSB 18.1 gr.

[Motorhead]

In .177 the JSB 10.3 gets the 80+ shots at @ 900 fps
In .22 the JSB 18.1 gets @ 40 shots at @ 865 fps

Very nice strings Motorhead
Thanks for setting the bar

Thanks, bear air link
I'll look into that

[bear air]

Sorry bout that, I don't know how to add a link. They are the Huma website and I think Jeff at Treniers has them in stock.

[Buldawg76]

Here's the front fill setup that has a gauge for the plenum pressure. from huma. Jeff at trainer can likely get them if he does not already have them.

Nothing to be concerned about bear air link
I went to the Huma website & found them
Unfortunately there is not one for the Discovery/Maximus platform
