Canadian Airgun Forum

I have had the rifle for years, still holding air, however it does not have a pressure gauge. That is a pain in the butt. I do have a small gauge.
Would it be possible to drill and tap the underside of the air reservoir tube to install the gauge?

It may be possible, but not advisable to do that because the tube is likely too thin and the threads on the gauge are likely coarse threads, meaning you would not have enough threads in contact with the wall of the tube to be safe.
Perhaps a method that would work is to tap into the end cap at the filler end and install the gauge there. it may be necessary to have a custom end block machined with a gauge. I had an Artemis PCP at one time that had just an end block with no gauge and it was a PIA because the only way to tell the pressure was to hook up a pump, in my case hand pump, and read the gauge on the pump, of course when the pumping got hard, because that was the at the pressure when the tube would start to fill.
Most guns have the gauge axial with the tube at the end block.
The inexpensive PCP setup I got for my 2240 has both a high pressure gauge axial with the tube and a LP gauge after the regulator. The material where the gauges are is relatively thick and plenty thread engagement.
My 2c.

Would not suggest drilling/tapping the tube itself, but you could whip up a spool to hold the threads similar to what is used on a Benjamin Discovery.



Or make a new fill end that incorporates the gauge. (preferable IMO)

Exactly, here are some pics of the gauges on my 2240:
Those threaded caps are pretty thick, like 6mm or more.

nice looking rifle Daryl, just as Gippeto said and if your really brave and confident
you can make it come out the bottom of the stock....

Ace, that is what I had in mind, however I'm concerned over tube thickness, due to the 3,000psi fill pressure.
From full, I get 24 good shots, then a shift in POI 1" down and 1/2" left, at 20yards on the 25th through 35th shots.
Thus, I fill the gun to 3,000psi on the 4,500psi carbon tank and count shots. I guess I will continue.
Thanks guys for your suggestions - Al - good idea, but beyond my old lathe at this point. The end cap comes off and it
has the normal male fitting under it. It's a really nice rifle to shoot and accurate as well, but is only a .22 cal. I have 4 .25 PCP's
that I prefer for plinking - double the shot count on all of them, over the Brocock.

Just went through 50 rounds (2 fills), nice shooting rifle. Of course, pellet on pellet at only 10 yards using Hades. Those pellets shoot well in .22 and .25 in all my rifles
of those calibres, including the HW97 springer.

Might be easier than I thought. Make up an end-piece, similar to what Al showed, that threads into the fill spout thread, that has a fill thread and the gauge threaded into it.

Hey Daryl,

I have the same Rifle -if you have someone machine a part to accommodate a pressure gauge, I'd be game to chip in for a second unit.

Cheers!

the part is available as Al mentioned its just a matter of installing it properly
make sure to de-bure the hole that you drill into the tube if your not mechanically inclined
then have someone that is do it for you

Ahh - Yours is the Concept 6. Mine is single shot. I bought the Best Fittings(I think) magazine gizmo for it, but never installed it. Works fine as a single shot.
I'm surprised it's still holding air - has been for 7 or 8 years now at full pressure, shot that off this afternoon, then filled and shot it once more.
I suspect these are normal 'readings', although I haven't chronographed mine yet.
Mine seems to like the Hades pellets the best, so far. 1/10" for 5 shots C to C, but only at 10 yards, rifle rested on the back of a folded blanket on a chair in front of me.

I get your drift, Ace. I would have to de-gas, then remove the fill spout to see what's involved with it's seal mechanism, etc & see if's it's a simple matter
to install one of the pieces like what Al showed for the Mauraders, perhaps with a threaded peg to fit where the air fill make foster fitting is located, or with
a hollow screw jointing the end piece to the rifle via, the foster fitting thread. I know what I mean, might not have the proper words.
I do have access to a good lathe at my bro's house - I had initially forgotten about that.
I would not want to put that inside the air tube and decrease capacity even more. As it is, I only get 24 to 25 shots form full at the same poi.
