tyronejk's POP 2026 build

[tyronejk]

My box o' poo arrived today. Lucky me has an ultrasonic cleaner this stuff will be taking a bath in.

budget tracking - current total: $94.80
- (excluded) $25 buy-in (I bought two extra feedneck-less guns but will be using the parts remaining after putting together two functional guns)
- $25 wooden rifle stock (thrift store find)
- $9 hose barbs (ASP)
- $17 12g bucket changer (eBay)
- $7.71 PVC pipe and fittings (Home Depot)
- $7.50 two macroline fittings and macroline (bought from hmcl281)
- $10.59 1.25" scope mount (eBay)
- $18 QEV (bought from JoeSchitt)

removed items that were previously bought but not used:
- $18 macroline fittings (eBay)
- $2.71 (exactly-definitely-not-fudged-and-back-calculated) worth of spare macroline
- $9.99 1" scope mount (eBay; ended up not using)

After extensive cleaning and cherry-picking the best parts, I have at least one decent shooter. I have enough parts for potentially one other gun and another body assembly I might try to attach to a wooden rifle stock I have lying around.

Man the gen 1 bolt cap looks so good with the gen 2 bodies.

[OpusX]

Very nice. Now that it works you can break it until it works most more betterist

[tyronejk]

The second enmey is together and functioning (sans feedback) and now I want to put the leftover parts to try to make this rifle work.



Step one was hacking apart this frame get the trigger assembly to fit in the rifle stock's original mount.


Which does technically fit but places the trigger too far forward to use comfortably. I wanted to line up the original trigger rocket with an existing hole I'm the wooden stock to make it simpler to retrofit a valve, but I'm not happy with the ergos.

[tyronejk]

This is what I'm thinking of in terms of packaging. There's a good amount of space hollowed out in the stock already so I think I'll be able to fit a 12g and hoses and valve assembly beneath the gun body and reg.


What is the general consensus on self-machined parts? I'm thinking about machining a 3way valve to fit in here.

[BrickHaus]

Self machined and or hacked and filed are the spirit of this whole thing yo

[tyronejk]

Sweet, sounds good to me

[tyronejk]

Minor update: ordered some 10-32, 1/16" barbs from airsoldier and a cheapo 12g bucket changer from ebay. I wanted to do some kind of integrated/hidden air system in the stock, but the budget is too limited for that and new macroline fittings are more expensive than I remember.

[BrickHaus]

You sure about using 12 grams? Wouldnt you need to get a regulator with a pressure relief on it?

[tyronejk]

Yup, I'm still feeding the CO2 through the original regulator, not a straight feed.

It'll look kinda janky in this configuration but my plan is to clean it up after the contest to make it more presentable.

[tyronejk]

Minor work today: turning down the OD of a reg for weight but mostly making it easier to fit in small spaces. Having a straight, uniform diameter is also helpful.

Ok thats sexy af

I was planning this same mod. Glad to see you didnt hit any passages at full cleanup! I was wondering if i would when i do it.

[tyronejk]

Today's update: I got around to CAD-ing up the valve and trigger. I'm just realizing I forgot it now, but those ports would be threaded 10-32 to accept hose barb fittings.

[gnarlynick]

Incredibly jealous of those of you who have CAD skills and machine equipment. This project has really highlighted to me that I need to jumpstart my CAD education, something I've been meaning to do for a while now.

Love the direction this project is headed, can't wait to see an eNMEy rifle.

[Magmoormaster]

Same, I have a drafting degree that included Solidworks classes but I work in architecture so I've lost all of it. It's shocking how much I've struggled with learning it again.

[tyronejk]

I highly recommend either Solidworks (~$50/year subscription for hobbyists) or Fusion360 (free for hobbyists). You don't need a super fast computer for anything relatively simple (e.g. model above).

It's not super intuitive at the beginning (YMMV) but once you start getting the hang of it, you progress quickly (until you get to more advanced stuff that is important only if this is your job, IMO.

[gnarlynick]

I followed a YouTube tutorial for OnShape to design a feeder for my son's reptile that I later printed out. It was quite intuitive after a bit. I just need to keep at it to cement the process into my head. Haven't done it in so long I've forgotten what little I did manage to learn. Too many times I've come into a point in a project where 3D modeling would have been beneficial.

[tyronejk]

Yesterday's update: adding a PVC body/stick feed. Cost $7.71 from Home Depot.


The trick here is using a Schedule 40 1" x3/4" tee fitting. The ID of the 1" pipe is too large for the Enmey body but the tee fitting has a small step inside that can be bored out to a close fit over ther 1.25" body.



Holes drilled to accept two mounting screws and clearance for a hose barb.

[tyronejk]

I realized I have budget remaining for macroline fittings, so I'm not constrained to leaving the reg/ASA dangling off the front of the gun. So I've order a couple 90 degree fittings and plan to attach everything like so:

[tyronejk]

Final purchases to fill out my budget are these two scope mounts. I plan to use these to mount the body and the reg. I could have made these myself but not for anywhere close to $10.

[tyronejk]

I made a little progress today. I got these scope mounts in the mail and while the 1" is to size, the 1.15" one is actually 30mm (1.17") and doesn't quite fit the body. So I bored that out.



I also found out that the reg body I turned down ended up too small to clamp well in the 1" scope mount. Luckily, I still have one extra, so I turned that one down to a nominal 1" OD.


Now that I have these parts in mounts, I'm second-guessing the final mounting solution. I originally intended to drill holes through the bottom halves of the mounts, screw them onto the wooden stock, then clamp the cylindrical parts into the mounts, but this leaves them sticking up quite high. TBD if I come up with any better ideas.

[StaticShocked]

Awesome! Looks great and i love the idea of repurposing the scope rings to hold the components
