    Thoughts on a quad stack coffin mag for the VZ61?

    I have a buddy that picked up a VZ61 parts kit and as 20rd mags are the largest available for the 32 ACP variants, could a coffin style quad stack be viable.

    The Sites Spectre for those familiar uses a quad stack that changes to a double stack within the magwell, and then feeds from a single stack. As it works reliably with 9mm and .40 I imagine the same concept would work with 32 ACP.

    With that said quad stack magazines have heavy springs as the magazine is essentially seperated into 2 double stack mags internally so you end up with a split follower and a spring for each side.

    Just wanted to see what everyone's thoughts are, I imagine this should be much more reliable than a drum while staying more compact. Have any of you guys attempted a quad stack design? If so what issues did you run into?

    PAQ-4C IR Laser Teardown (1993-1996 Board Rev 0.0)

    These are decommissioned full power units that had their lens busted with a screwdriver. Upon Dissasembly I found the outer lens cracked, the focusing lens was undamaged, but the laser diode's glass was busted. Despite this as you can see the unit still works. The PCB although we'll made doesnt seem too complex, the main IC appears to be a TLC251C but I still need to document voltages and currents around the board to ID a suitable replacement laser diode and all of the other components.

    The end goal is a printable DIY full power laser that anyone can make for ~$100. Using the PCB layout I plan to have custom PCBs made to fit a more modern LAM format, reusing as much as possible from the original PAQ-4C. The turrets seem possible to print as well out of nylon, the only hurdle there is the spring which has indentations and prevents the turret from walking/provides the clicks you feel and hear.

    Tools used for the teardown: Dremel with cut off wheel Drill Press Flat head screwdriver for

  • I still feel like the concept has true potential, but its going to take a good bit more testing and development. A solid fuel motor with consistent thrust would be needed before you can really test further as any inconsistencies with the burn rate is going to alter its stability and flight characteristics. That alone would increase the velocity and flight range which im sure the feds wouldnt be happy about...

  • Unfortunately after looking over all of the videos within the Google link for the additional documention, although a really cool concept it looks to be far from "functional". The rocket quickly begins to fly erratically in all videos, never seeming to stabilize or correct its trajectory which defeats the point of all "guided" electronics.

    This may be due to the poor motor casting using sugar propellant causing sporadic burn and thrust characteristics.

    Either way it's a very cool concept but seems to be far from a reliable finished design.

  • I doubt I'll ever have the funds for a 249, but I appreciate you putting it out there man.

  • I dont have one in hand yet, but from what a guy in the matrix sent it looks to be "seemless" or atleast a very flat seam. McMaster lists the ID surface finish as 31 ra.

  • Sent you a PM

  • Well the goto budget barrel has been a fencepost, however McMaster offers a 304 stainless steel tube thats 38mm and pressure rated to 1,600 PSI. 1 meter of this tube is around $46 so you can get several barrels out of it for cheap that will be both stronger than the fencepost and be uniformly manufactured for tighter tolerances and better gas seal. One user on the matrix has had his barrel survive some explosives going off inside of it.

    38mm Fin Stabilized Smoke Projectile - Current Prototype Model

    Im designing a prototype smoke projectile for 38mm launchers. This is designed around using a 38mm 12" barrel for the Odin Launcher. The smoke composition will be TPA based. I'm going to attempt an IR/Thermal blocking smoke composition but if all else fails it will be the same TPA composition that Invention Incarnate uses.

    Design Highlights:

    • Von Kármán ogive nose cone, optimal for subsonic projectiles.
    • Polygonal rifled integrated pusher using an extended 4.5" Mathetatics & AWCY? M.I.L.C shell, provides initial rotation.
    • 6 curved folding fins, spring loaded for stabilization and further rotation during flight.
    • 3D printed housing using a DIY phenolic liner for heat mitigation.
    • Heli
  • I was actually just looking into it more yesterday and the more cost effective barrel option for strength seems to be the 304 stainless tube from McMaster that's used in the SS 38DD. It's rated for 1,600 psi and a 1M section is around $50. So you can get 4x 8" barrels per $50.

  • I would be interested in a 12" 4130 barrel and a 1 piece solid breech block. I'm planning out a build and designing a ridiculous 10.5" IR blocking smoke round.

    What's the strongest 37mm launcher design?

    I'm planning to work on some DIY 37mm smoke grenades. The goal is to make a DIY printable/easily acquired 37mm screening device that outperforms the M713 40mm white smoke round.

    As such packing as much smoke composition as possible within the round is ideal. These rounds will be fairly heavy as the smoke composition includes a resin for waterproofing them.

    So im looking for opinions and personal experience from the community on which launcher design is the strongest and can handle launching heavy projectiles? I've seen the Odin, Nameless, Pipe Hitter, NT79, B.A.L.L.S, etc.. with most of them having DXF files for reinforcing the chamber. For designs that don't, I can modify them to do so. But I want to gage the community and see which platform I should start with.

  • Yes, TwinBros patented it and then sold the patent to RareGreed. Fuck both of them.

    I saved these off of the Fosscad sub before it got nuked. I believe a couple of settings are different than 300blk's .3mf file, so im not sure which are the most up to date.

  • Gyroid baffles in 17-4 or inconel sure, but even in PA6-CF that's going to be a no go. The material will simply be too thin and will either deform rapidly or break due to the forces especially if close to the blast chamber where pressures are the highest. What caliber are you making this for, barrel length, and what material/thickness is the airsoft suppressor? There's a reason every 3D printed suppressors design that works for any reasonable number of rounds has thick walls and infill, you need that density to hold up to the pressure and forces at hand.

  • There's some good videos on Odysee, but a lot of it just comes with time and getting better at whatever CAD software you're using. There's typically a dozen different ways to do the same thing with some ways taking 10x as long for the same outcome.

    "Larger" Brace option now sailing

    As was requested, the brace tailhook for my TX7 Remix has been doubled in size. The blade is now twice as thick, and the brace arm has had its geometry updated to match the right side of the tailhook's profile.

    Included are .STL and .STEP files for both parts, so further modifications can be made on an individual basis.

    This brace is a remix of @CrankFastle "CRANKS DROP STABLE SKELLY"

    The brace arm has been changed to work with the folding hinge from @philphisher "PP MCXish 3D Printed Folding Brace"

    As such, this brace should work on any chassis or lower with a rear Picatinny rail section.

  • Sounds doable, essentially a revolver action in a gatling gun that indexes the barrels when the trigger is pulled.

    The question is how do you add an FRT component that resets the trigger in a traditional gatling design?

  • The FTN.5 seems to be the quietest can at the moment.

    Short and lightweight will always mean louder, its just the tradeoff you have to make. Larger with more baffles tends to mean quieter with the tradeoff of size and weight. Although being 3D printed the weight isn't anything like 17-4 stainless or inconel.

    I'm working on a 22lr version of the B&T MP9 reduced back pressure can. It's a flow through but massive for a 22lr so the increased volume should make it pretty quiet. But shes big. Unlike most print in place cans, this will need printed individually and assembled due to overhangs and support constraints. It's direct thread for a 3/4x16 to 1/2x28 adapter. Still a work in progress though.

    TX7 Remix BETA

  • Beta is live

  • I was about to release it but took some suggestions on reddit and closed in the bottom of the chassis adding a molded section for the rear 5mm of the beavertail and holes on either side for the rear-most pin in the frame. This way the rear of the TX22 is secure, this should eliminate any potential for the charging handle to jump past the rear sight. I need to verify the pin placement and the beavertail geometry as the model of the lower I was using is rough.

    Im also playing around with the front geometry to fit FTN 3, FTN 4, FTN 5, Dim it Down, and the new OP22 if possible.

    I'll try to get something out in beta this weekend.

    Bending a solid in Fusion 360? Making an Unobtainium Zastava M70 Disconnector

    My brother picked up a Zastava M70 pistol from a pawn shop, which appeared to be in great condition. However, upon firing it, he found out it had been touched by a GuNsMifF practicing the art of Bubba... The gun wouldn't fire after multiple trigger pulls, then the hammer dropped, and nothing happened. However, the round went off as he touched the slide. The culprit was a botched "trigger job" done to the disconnector, which actually snapped a section off when the round fired.

    Unfortunately, there aren't many replacement parts available, so buying a new one is out of the question. I've only found 1 youtube video that even shows the part remotely well as most videos do not show the fire control group being dissasembled.

    Once fully modeled, I'll 3d print some for him to test fit and file into shape as needed, so that I can tweak the design and then send it off to SCS. My issue is trying to bend a solid within Fusion 360. I've tried projecting the solid's geometry within a sketch and the

    Polymaker PLA Pro Metallic Gold causing nozzle clogs?

    cross-posted from: https://forum.guncadindex.com/post/166583

    This is a fairly new 0.4mm hardened nozzle in a Bambu P1S, the nozzle has maybe 100hrs on it with the only other filament being Overture PLA Pro Black. I switched to the Polymaker Metallic filament, got it calibrated, then printed 2 good parts. This handguard has since failed twice with the nozzle getting clogged. The longest part is the last print where it made it roughly 85% of the way and clogged before printing the threads...

    This is my only spool of the material and I only have enough left for 1 more attempt, it's a nearly 18hr print. Is the Metallic glitter within the filament what's causing the clogs? Any tips or suggestions to avoid clogs with this material? Yesterday I took the extruder about and cleaned it well thinking that it could be contributing.

    First print with Siraya Tech PET-GF

    First print after calibration using Siraya Tech PET-GF in FDE. Print came out nice and is surprisingly strong at only 25% gyroid infill. I used 8 walls with 6 top/bottom layers. Printed at 300C nozzle with 80C bed on a Bambu P1S using a Darkmoon CFX build plate and printing from a 60C dryer. 0.4mm nozzle at 0.16mm layer height.

    Finally got my support settings dialed in - TX22 Boomtube 22 Mag Extension

    This is in Overture PLA Pro using 0.15mm layer height with a 0.1 fuzzy texture and 99% infill. It's 300BLKFDE's PA6-CF settings with a PLA Pro profile and modified support settings.

    17hr print time, yes PLA can be printed much faster, but the increase in quality is worth it in my opinion.

    HELP: Threaded hole printing too large/loose

    Tested a print of a muzzle device after calibrating some PLA Pro. The print came out looking great. However, the 1/2x28 threads in the ID are very loose, so much that with minimal force, you can pull straight past them.

    So, I've seen a few different ways to fix this, but I wanted to see what the community agrees to as the "best" practice to adhere to.

    Do I adjust for shrinkage, add in additional tolerance in the modeled threads, or do something else entirely?

    Need some help with PETG on Bambu P1S

    I've spent the last few days trying to get PETG to print on the P1S.

    PLA and PLA Pro printed great with no change to settings and just using the default 0.4 nozzle 0.16mm optimized presets in Orca. Examples: https://imgur.com/a/lx7KzRA

    PETG, on the other hand, has been a pain in the ass. The preset for PolyLite PETG failed on my first print miserably, so I aborted after the first few layers. I then attempted a flow rate test as it was under extruding, that test was a failure, and continued to fail until I increased the flow rate from 0.95 to 1.197. At this point, I adjusted it per pass 1 and 2 but was still having issues. I printed a temp tower and decided on a 255C first layer with 250C additional layers. Still no dice, so I looked for suggestions on YouTube. Found a guy swearing by increasing the temp to 279C on the P1S. I tried that, went through all filament calibration tests from flow rate, pressure advance, retraction, max flowrate, and VFA. Tests were looking good, so I trie

    P1S Firmware Versions?

I've seen mentioned that some versions locked down more control over the printer, but I haven't seen mentioned what exactly it changed or what versions did so.

    Help me choose a printer | X1C vs P1S | What's your preferred filament?

    Looking to finally make the jump from my old Ender 3 to a better printer, I've upgraded the Ender quite a lot but have run into multiple problems over the years with custom firmwares. During my last move, I snapped the SD card slot off the main board and have had issues getting the new one back up and running. With all of that said I'm ready to just buy once, cry once, and get back to printing.

    The options I'm looking at are either the X1C or the P1S. I wanted to get opinions here, as from what I've found so far, the P1S seems to have the same print speed/quality, just minus the AI, and upgraded steel components. How capable is the P1S stock, and what upgrades, if any, would be recommended?

    From what I've found, the AMS 2 seems to be the ideal choice over the OG AMS due to the drying function and more user-friendly design. It's $120 more for the AMS 2 combo than the AMS combo, so for those of you who have these setups, is the AMS 2 worth it?

    Other than the printer selection, what ar
