Benjamin Marauder fill pressure question

[Airgun-Revisions]

@Airgun-Revisions
What kind of adhesive does the factory use to secure the adjustment screw (part #9 on your schematic) on their regs? I recall that part on the one in my Marauder Regulated was made of a really slick plastic.
Thank you,
Chris

Believe it or not it’s just super glue for plastics. A lot of stuff comes through McMaster Carr.
Another trick that I do to keep tension but still adjustable is heat up a rounded punch 1/2 -3/4 the diameter of the hole and push it in part way.

Well, we are dealing with a one inch ID or a little bit more. Those three screws are holding 1000 pounds each.

There was a test of the (after market) aluminum air tubes. I think it failed around 9600 psi. The aluminum tube wall sheared, not the screws. There is a good safety margin here with both the steel tube and those three screws. Less so with the aluminum tube. Steel does not really fatigue if not taken beyond elastic limits. Aluminum fatigues with every cycle and will be directly impacted by fill pressures.

@Airgun-Revisions - Rich is the guy to ask. I find that my regulated Marauder / and HFT challenger perform best <3000 psi and i refill at 1700 psi as i do notice a change in accuracy if i go below this pressure.... i think that the manometers (gage) are less than accurate which could be part of the problem...
Hey does anyone know a very accurate gage that fits the marauder / challengers?

Tensile strength for one screw is 170,000 psi but sheer strength is more important. Tensile is elongating till failure point. The head of the bolt sitting flat in the counterbore also makes for added strength.
But at any rate yeah it’s over engineered. That’s the way we like it.

Crazy right. Glade you enjoy. Getting more people up off the couch and shooting is what it’s all about.
Right now I’m seeing more and more husband’s and wife’s starting out and this gun perfectly fits both.

Rich, do they make a more accurate gage for these platforms... digital?

I’ve not personally used them. My way of thinking is 1” gauges are for reference only. Also I’m not doing competitions like you so this comes down to what other shooters think of the product. You want 1/8BSP.

This happened a week or two ago. The two near targets was a miss calculation.

Eric a good guy and a heck of a shooter from what i hear. He’s got some really cool guns too. I’d like to go up and shoot some of his guns some day.
