Warning pic heavy:
Since my return back to airgun’n I’ve been wanting to do this little project to my 2240 and running it on HPA and being able to use a regulator as well, some might remember me saying that I don’t like CO2 cartridges and that’s why my 2240 has just sat around not being used much.
So this was my reason to run HPA on my 2240 and finally getting some use from the gun again. Being that I was pretty heavily into paintball I had all that I needed laying around to make this project work without having to go out and source the parts.
All I had to get was two small pieces of aluminum plate to make tank brackets. One bracket was sent to me some time ago to me from Todd thanks again buddy it’s finally coming in to good use, :wink: all I did was cut and shaped another bracket from his or as close as possible. :lol:

I must also mention this is a "WIP" so I will be changing things up a little as I go along with this project but as of right now the gun is shooting great and I’m pretty happy with it. This build wasn’t about power that’s easy to achieve, it was more about max shot count on one fill while remaining under 500fps and keeping the shot spread +/- very close. Also before I forget I’d like to thank TH for the 14” barrel. :wink:

Before I go on I would like to say originally I was thinking of mounting the bottle in-between the stock, like in this first pic but then changed my mind and decided to not chop the stock up because I could easily swap the stock to my 1322. But I might still consider this idea after it was all done. :?

First is the disassembly of the gun
Image
Next I polished the hammer and cut the tip off the top on the trigger and polished up and deburr’d the sear. Also lightened the hammer spring and valve spring.
Hammer before:
Image
Hammer, trigger and sear after:
Image
Next I drilled and tapped the valve and cut a little off the top to put a line fitting on, also did the same to the tube end cap. And also angle ported the transfer port.
Image
Image
Image
Attached high psi hose from valve to cap:
Image
Attached bottle and tested for any leaks before moving forward.
Image
Next attached the tank to the gun for fitting and alignment.
Image

Image
Cut out and attached second bracket:
Image
Image
Next attached the regulator and fitting also need to make a bracket to attach to the barrel, but I’m debating if I’ll leave the tank on the front of the gun even though it has a nice forward feel to it, and acts as a forestock.

lol... you noticed that did you, good eye :lol:
yes this was an extended bolt prob i got with some parts so i decided to use it but it had no bolt handle with it so guess I'll make one or buy one, but its doing the job for testing purposes :wink:

nice work ace, but i think u gonna need some weight at the back? did u make those brackets yourself? u are u gonna put a stock ?

Every things still up in the air with the project, the important thing for me was getting it to run on HPA now that it works with all my attachments I'll see what changes I'll make cosmetically i know she's not the prettiest looking 2240 out there but she shoots real nice and consistent :lol:
As for balance its actually quite nice i know it looks front heavy but ones your hand is under the bottle it balances quite perfect just kind of sits on the hand no front or rear tilt. 8)

Mario! Looking good!
I am with the others on this! Pop a small hole in the stock and fill it with sand! You'll get some good balance that way!

Post subject:  Re: 2240 project HPA and regulator WIP

Ace gave me a preview for this gun. I know it looks front heavy, but it's for the most part very balanced once you have your hand on the tank. 8)

I would prefer a rear tank setup, but the current configuration works very well with the tank acting as a foregrip. A rear bottle setup would require some sort of foregrip because the stock tube is too narrow to hold on to.

All it needs is a steel breech and a nice scope to finish it off. Ace did a nice job tuning the trigger too.

Sweet! What pressure does the regulator give? Have you tested the shot count yet?

Ace, I admire you for everything you contribute to this forum, but sometimes (and this is not just you) I wonder, considering the audience, who would gainfully follow this kind of build. It seems we're taking the sublime to the ridiculous (if not, to a level that is not necessary to reach a simple goal: to run HPA on your 2240. Why a "huge" tank on such a little carbine?

Why not just buy yourself a 2240 Hipac? If your goal includes more shot capacity, how about installing a longer tube and get an extended Hipac? What's the true advantage of a regulated air supply in a gun that cannot, in any way, be modified to shoot over 500 fps without making it either another gun (e.g., a 2260) , or a restricted weapon? If you want a legitimate air rifle, why not use a 2260 tube and add the 2260 Hipac package to build a legal PAL-rated rifle that will shoot as hard or harder than what you've built here?

:drinkers:

:lol: Not trying to be a plick, honest; just adding another angle here to stimulate a bit of interesting repartee,

So, like, when can you build me one of these?

:wink:

I'll speak as a retired person (one who spent several happy years in London in an earlier life - ex CT-H&E head office employee), and acknowledge the wisdom these members have shared with you. I'll share another option with you; I, too, have returned to air guns after several generations, and I have a common "retirement issue," which you may not share: Having to make spending choices rather than spend now - save later, as the younger crowd sees things.

So, for what it's worth (FWIW), there are a number of non-pal air rifles that can almost match the performance of the models suggested, albeit without the higher build quality and also at a shorter range. So, here's my thought for consideration, depending on whether my intro fits your scenario: Try a less expensive rifle as your first in a long time, and while you do so, consider seriously whether your interests will be limited to plinking, or in moving on to small, medium, up to big-game hunting.

Here are a couple of suggestions (I own both), and if you direct your thread to starter guns, I'm sure you'll get many more suggestions. First is the Benjamin Nitro Piston 22 break-barrel (can be purchased for less than $250, otherwise look for something else) - an easy-to-break/load rifle that that carries significant respect for its accuracy at medium range (35 yds or less), and which can easily be upgraded to a hard-hitting 750+ fps rifle with a little work (help would be easy to find here if you have your PAL).

The second is the Industry Brand QB78, which is also accepted as a pretty accurate rifle at medium range, and comes in a non-pal .22 cal CO2 version. No pumping, good medium range power and a decent number of shots per 2-CO2 cart charge), and also can easily be converted (again, with experienced help if you've get your PAL) to a 800 fps-shooting PAL version and also to High-Pressure-Air (HPA) with a few dollars worth of modification. You can also convert it into a 9-shot repeater for another
$100 or so. Your cost for the basic is approx. $130 (usable at medium ranges out of the box.http://scopesandammo.com is a good starting place to find this one (Proprietor's name on this forum is AirGunEric.

As a disclaimer for "advisors" looking for angles of dispute, I will note that the trigger plays an important role in your satisfaction with an air gun rifle, and my mentions, and air guns of their price range, can be improved dramatically with a bit of trigger tuning (again, likely available here).

So, if you decide to "try-light" picture any rifle in this price range with a much smoother trigger. If you can't picture it, ask if someone will do it for you. Areas such as trigger mechanism and exterior finish play a key differential between good, moderately priced rifles, and good, starter-priced rifles.

Then, if you decide to go farther than rifles of this range permit, they are relatively cheap giveaways, but also can be easily sold here for 60-70% original price (especially if you have made any extras mods}, Just sayin', if you've got the retirement blues, or you're just prudent or unsure about the sport at the moment, you can get started for less than $150 bucks at get at least half of your investment back if you decide it's not quite what you expected or were looking for (or to put toward a better rifle).

If this makes sense in your scenario, just tell the guys you want to invest minimally at first with the interest in escalating after you've tested out the gun capabilities and the sport in general. I think a few will back me up with a few more starter-gun ideas.

PM me if you like. Others are better at specific hardware recommendations, but I can help with the "senior" perspective, which is hard for most of these guys to envision as having any kind of impact on air gunning decisions.

Good luck.

Murray

P.S. to readers who have made it this far:
I, too, can can far too verbose (long-winded) as some of you. Even though it's not my usual way of doing things elsewhere, I tend not to edit to be more concise in this environment, and as a result, I also often miss mistakes, as well as stupid "auto-spelling" corrections. In Other Words (IOW), I'm not claiming to be perfect, but I do use paragraph breaks consistently, and this helps us gain more efficient readers of our posts. Honest. I'd gladly give you some tips on using paragraph breaks if you're interested in learning that skill.

P.P.S. If you had no interest at all in what I had to say, then I can also assure you it wasn't because you saw one long. massive block of copy that you weren't sure you could make it through. :mrgreen:

P.P.P.S. This P.S. string is not related to any of the posters above, in this thread.

You really,really seem to like to hear yourself talk; don't you? :roll:

Can't you just appreciate what Ace has done; without adding your unwanted 2 cents to the topic?

And you are doing a great job of "trying to be a plick" - actually.

Well....the "true advantage" of a regulated air supply using that (as you called it) "huge" :roll: tank is super-consistent velocities for a TON of shots...plus, the tank DOES make for a fairly comfy fore stock (I've done a few like that now). If you paid attention to Ace's original post instead of just looking at the pretty pictures, you would have noticed he stated that he wasn't after more power, just more (consistent) shots per fill.

Yes, he could have went the Hi-Pac route, but, to be honest, I think he'll be better off with his current set up. If using the Hi-Pac, you're ramming 2000-3000psi into your valve which means that you will need a much stronger hammer spring to crack the valve open and seeing as Ace is using the stock trigger group (as opposed to a P-rod trigger) that stronger hammer spring will result in much more force being applied to the sear, which in turn makes for a horribly heavy trigger pull on a stock 22xx trigger.

Even if he was using a P-rod trigger/Hi-Pac combo he still wouldn't get the amount of shots he will get with his current configuration....and wayyyy more consistent velocities than the Hi-Pac, too :wink: .

Was there really anything gained by personal insult here? Just because the question wasn't phrased particularly well didn't mean it didn't raise some interesting points, as addressed by Todd above. Email and on-line discussions such as this are notoriously easy to mis-interpret the intention behind people's words, so cutting each other a little slack is no bad thing.

Group hug? No, maybe too much :)

That bottle has two burst discs suggesting a regulation function.
Is there a reason for going with the inline regulator with/over the bottle based one?
