old cetme project reupload
at this point, its pretty much complete. test firing went well– some feed issues related to the magazine and the ramp angle. i bought a pmag and modified it to fit– just need to test it. also need to make a screw for the rear sight.

starting from the beginning. parts kits just came in. trunnion still attached to the cut up receiver, as is the charging handle tube, and rear sight. the flat is in the next pic, along with the remains of the receiver after i cut off charging handle tube and got the trunnion out. last pic is just mockin stuff up.

time for real autism hours. making a shell deflector for the receiver because autism, and the original receivers had them but they were part of the stamping. cutting it from the 18 gauge steel sheet i was practicing welding on earlier, cutting it, and bending it with pliers to meet the contours

initial welds cleaned up. probably the toughest section of welding on here, high possibility of blowing through the material when getting near an edge.

next is adding some material to fill the gaps, and try to correct some bad filing. never got corrected, and the radius that is on that corner got filed flat on that spot. i feathered it out well though, and its not particularly noticeable final product.

drilling the hole to gain access to the barrel trunnion dowel pin when its in.

i failed to take pics of the barrel getting pressed into the trunnion, or drilling out the notch on the barrel for the pin, but it took place around this time.

next the trunnion went into the receiver, got oriented properly, welded in place, cleaned up and welded, and cleaned up again.

next the charging handle needs to get welded on. so all the parts that got freed up in the first few posts need to be sandblasted. so i made a blasting box to recycle my media and keep things generally clean. it worked well. here are the parts after.

after the charging handle is oriented properly and welded on. those welds were later cleaned up and the correct contours filed in. around this time i also drilled a notch into the barrel for the front site dowel pin, which became a nightmare as the bit wandered off and corrective and somewhat hackish action had to be taken.

also a look at the underside of the rear sight base, and my setup for welding it on

gettin towards the end. miscallaneous bits screws, handles, etc were blasted and prepared for parkerizing, as was the rifle itself. parkerizing solution obtained online, and the setup cobbled together along with a discounted water heater element from online

i wanted mine to be a little unique, so i got in contact with a surplus seller (in spain) to get one of the old style, original cetme L handguards. as far as i know none of them have ever been imported to the US, so i may be the only one.

had him send it to a friend of mine stationed in spain, then he USPS it to me.

final product


total time ~150 hours. maybe a bit more, maybe less idk i didn't track it. could have finished in the 30-50 hour range if all i cared about was function, but i wanted this one to be nice.

I just made the rear sight screw with my dremel. Its 3 components: threaded rod, a nut I ground into a circle, and a knurled thumb nut. Note the 1mm hole I drilled into the end for the roll pin that interfaces with the rear sight nut. Gonna use 1mm wire instead, because that rollpin is a pain and I fucked it up anyway.
I still need to sandblast and parkerize this, and I should really weld it together but I'm lazy so ill just use red loctite


File: 1539883643784.jpg (515.37 KB, 1791x1344, WP_20181018_09_41_37_Pro.jpg)

ok done
almost perfect


comfy screw


so this isn't actually build autism but it involves this rifle so i'll post it here
attended a 16hr rifle training course last weekend, and it didn't go all that great lol
i learned a bunch of shit, just not shooting related. luckily, the shooting stuff we did wasn't really new ground, and i wouldn't have felt like i was gettin pushed anyway. consequently the class didn't feel worth the money
now onto the problems. so my first problem was i started getting malfunctions, immediately. like back to back, nonstop malfs. for one, it looked really bad because that was my first impression on most of the people there, and it was a rifle i had built. up until this point, i hadn't experienced anything like it.
long story short, my magazine catch screw wasn't in all the way. that allowed magazines to change position as the bolt passed over them, and thats why it wasn't stripping the rounds. i fixed it probably 3-4 hours into the course. if one looks at the screw, theyd notice it has a slot cut into it for a slotted screwdriver. almost certainly, this screw is intended to be loctited in the fully screwed position and never, ever disassembled. which is exactly what i did the night before– detailed stripped my rifle. so lesson 1– loctite everything that needs to stay tight. lesson 2– if a rifle is working– dont fuck with it if you need it to work
the next issue was with magazines themselves. this one wasn't as common, but it popped up a few times. so since im in the incredibly restrictive state of california, i have almost no chance to test my 30rd magazines extensively. occasionally i'd have a cartridge that failed to be stripped from the magazine. after looking at some old, worn in 30rd mags from a friend, i noticed that the front lip of the magazine has worn down areas where the cartrdige hitting the aluminum lip has caused low areas to form. on mine, those weren't there since they're brand new and it was still a sharp corner. honestly this seems like an out of spec issue, but his were actual USGI mags, so it must just be how it is. today i rounded out the sharp corner with a file, and cartridges leave the magazine much, much more smoothly. i think if i had both of those things in check, the class would have been a lot more enjoyable.


everyone else at the class was kinda meh. they were mostly boomer tier semi-knowledgeable (the worst kind of knowledgeable) civilian types, with fancy gear and poor fitness / firearm understanding. there was one swedish infantry guy who was my favorite dude there and was a decent guy to train with.
other stuff with my rifle: the iron sights suck. they're ok, but the front post is a bit too fat, and the rear sight is way to obstructive (imagine m16 peep sight, but a square block thats twice as wide). during good lighting, they're alright. as soon as light is fading, they're fuckin impossible to get a sight picture.
also the lack of the hk style 'slap' bolt release is really shitty, the bolt catch is incredibly awkward position, and the rivet used to retain the spring loaded charging handle is sharp- so it will slice you open during remedial or fast reloads.
other than that shit was ok. there was a former delta guy there who gave us some incredibly brief combat medicine instruction, and i got to shoot the head instructors m4 on fun mode which is new since ive never shot shoulder fired stuff full auto before. we also shot longer range stuff, 2-400 yds which i haven't had the opportunity to do since i'd only done 'simulated' long distance stuff in the navy.
as for gear wise, despite all the shit i got from all the boomers there, my ALICE gear was set up great. shit just 'works'. theres not nearly as much of a difference in parity between a proper ALICE setup and the more modern high speed shit as they'd think. but its way, way better for long distance movement and general weight distribution. most of these guys seem to consider themselves in the same realm as SOF/infantry when it comes to what their role would be in a civil conflict/emergency situation. besides the fact that there aren't any standards in place to actually hold themselves to, they equip themselves in a way that assumes they'd have access to mechanized transport and supply lines just like the military does– so they're front heavy filled out plate carriers, with little water and fuck else. in reality an individual could only expect to have a role much more similar to a guerilla fighter, where movement is paramount (and where wearing 40lbs of bodyarmor without any water, food, and a lack of ammo is suicide)
autism over. i very lightly got into it with one of the dudes down there and honestly just let him do his thing. he was just too clueless. swedish guy really got into it with one of the boomers civies about firearm design. thought the poor dude was gonna have an mannerism

gamers rise up


like reduced sized targets at shorter ranges


looks like a comfy range


do you have to use milsurp ammo or is that just with G3/HK-91s with fluted chambers?


extremely comfy, its a nice range. up real high elevation– top of a (mountain?) hill, bunch of targets and ranges, good target hangup system, beautiful surroundings. so much better than my shitty faggot local range.
nah you dont have to use milsurp– even with G3s and stuff. roller delayed blowback stuff is more susceptible to changes in ammunition, but most commercial loadings are close enough that ive never had problems, although i've only shot a few diff loadings through it. mostly shoot 62gr Wolf military classic series
i actually had a guy recognize the gun and he was rockin a PTR91. first person to actually know what it was


is it better than your local range though?


it is so much better than my shitty faggot local range
