Next Week Update


This thing is big... Went to the Shooting Range yesterday for the first time in a few months (calling me "rusty" would be saying the steel on an abandoned-in-the-1890's mine cart rails are tarnished.) so that was gun. Anyways, before I took off, I grabbed a box of 50AE (hollow point but whatever) and yeah... I never realized how big this thing is. the 9mm can fit inside of the hollow point... Anyhoo... The 50AE does not fit in the lower of the model I have. Technically it does, but it has like... 1.5mm of clearance total. left to right. SooOOOooooOOO Where does that leave us? I think I'm going to continue with this model as-is, because the 45ACP mag fits (dimensionally) So that means getting out the table saw. I can hog out most of the material that way, and be alright with what's left. I bought some MoldMax 40 for this. going to do a 14NV for the skinjob and back it with that. this way I don't have to invest in a vacuum chamber anytime soon. (though I'll need one eventually.) 

The issue after thus is twofold. I'll need to redesign the lower to accept the larger magazine of the Desert Eagle. I do want to use off the shelf components for this as it not only reduces downtime but adds realism by using proper materials. instead of a resin, per say. The only issue with this is that there's only a 7 round magazine for this caliber with the eagle. Now, most magazines say they're 15+1 meaning they have an actual capacity of 16. so I'm curious to know if these are just unlisted that way. IF I had, say, a 10 round mag then I could simply cut it down to fit. but alas! I do not. I will continue the search for one, but in the end, it must be what it must be. 

I'm still musing the construction of an armed and fully operational 50 Cal version. I figure the lower receiver should be titanium, but I have zero math to reinforce this claim. that being said, Such a section of plate is well over $700 to purchase; and that is just the materials cost. Tooling and Machining are another huge hole-maker. We'll work out all of the design details for now and leave the rest to time. I'd love to have that, but there are a number of fully functional firearms that I can build prior to a completely custom machined space pistol. There is a thing i once knew that i have since forgotten... Titanium sticks against everything... It no slidey well... oops... If i had remembered that. i might have looked at this differently... The lower receiver will have to be steel. no question now. the upper might be able to be titanium.  why am i so gorram hellbent on using Titanium?! We have so much work to do before i can settle on a material like that. though i believe that having something as tough as titanium would be beneficial in areas such as the muzzle guard. high-impact prone ones. i'll def. make the trigger guard out of titanium.

I remembered the origin of the hell-bentedness: Space Gun. This thing needs to be strong and lightweight. Thus titanium wherever i can get it. There will be some serious materials comparison in the near future. I'll work out all of the mechanics in a bit. but one thing's for sure. This is going to be fun!

Midweek Update

So, It's been a weekend, The printer was clogged during most of it, but the important thing is that I've been printing pretty steadily since then. I have the barrel, receiver, trigger, both lights the laser assembly, and the left side finger guard is printing as we speak. The next part I'm going to print though, is the two halves for the magazine base. I also need to get some 50AE Rounds to compare to the barrel opening. Or I could just measure it... could be worse things... I'll go Wed. to get a sampling. god it'll be good to be back on the range again.

What's the next step after this? Sanding, and filling, and fitment, then we get molding and casting,  I need to get a decent set of molds for the overall gun. Once I get a solid magazine contender I'll have a straight up way for figuring out how to make the receiver. Once I get that, I have already figured out how to make the magazine disengage, I'll have a shallow hook that's solenoid driven push down on the battery contacts, which will be spring loaded from underneath, and have a little ratchet section that locks to the inside of the slide, then you can pull the magazine out and put the new one in and once you cycle the slide you're set to go! 8 rounds/mag just like it should be. wait a minute... I don;t need that, I'll have the slide lock open and have the controller just not cycle anything then. Or, I'll have the slide ride on the solenoid mech and then there'll be that stereotypical clicking noise. that way I don't even need a microcontroller. That would be ideal. I could just use a pot and dial in the strength of the solenoid. That sounds pretty straightforward. That means it will not be. Oh well...

Oh shit how will it count the rounds?... Well, I guess you could say that idea backfired a little... Regardless, Ill have to throw a lotta junk in there before I get too far. It looks like I will have to invest in the creation of a desktop rotocaster... 

I might go with the 45 magazine for testing, especially because I already have it on hand. I'll have to pick up a tad bit of square tubing, probably 1" and some shafts. I think I'll make a spring loaded section, to keep a looser tolerance. but i'll design that in another post. 

For the electronics, I'm looking at a stack of LiPo batteries in the magazine, a small one in the light, which will be a standalone system, i think, i gotta see if the light deactivates when reloading, regardless, then i gotta find a solenoid, spring, decent terminals, I should set up a shopping list. I'll probably just use a pro mini and run with that. What else, OOH! Right! SparkFun sells 0.2mm SMD LEDs so it looks like i'll even be able to do muzzle flashes! 

oh... ok... that's very different from what i expected... So yeah, looks like i'll be splurging for a Desert Eagle magazine... Holy crap that's big... Not to worry, that just leaves more room for moar batteries! time to order some shiny magazines and a new speaker for it. I can hide the speaker in the top of the, chamber we'll call it, and have it project down and out of the front of the barrel. I should look into super small data size mp3 chips...  The Teensy Audio Shield is looking like a decent option, at just 1.5x1.5 it is definitely small enough to fit vertically in this system, I'll have to see if that's the best way to go about this. or a two minute internet search reveals a ~22mm square audio board from Aliexpress. We're going to try that first. It even comes with a micro sd card slot. This could be our ticket, i'm not sure, but maybe, That would definitely fit into the light box, We'll do some shopping around first. The other main issue, is the solenoid action is shorter than what i need for the slide. that;'s jsut an offset lever, but i might need a couple of levers for this to work right, and that's... got it. not the numbers, but how to ensure i heave enough space to make it work! General Specifics to follow.

I found a wonderful outline of the magnum, and printed it out to be something akin to an assembly guide. I scaled it up a tad to fill the page more, 117% actually, and it may have been that 100% was juuuuuuuuust a tad undersized. Because i mean EVERYTHING Lines up, the trigger is a little different in shape, but I couldn't get this kinda accuracy if I tried. Anyways, I might make a pocket pistol 45 for IRL just to save on the materials cost, as i think the receiver will have to be titanium in order to withstand a 50AE, but who knows? OH MY GOD Halo Golden Gun!!! WOOOOOOOOOO!!! I'll make that as blocky as the original CE and cast it outta brass. WOO HOO For CULTURE CROSSOVERS~! man, that thing has a magazine in it, That's probably when they figured they'd make the mag size accurately. i dunno yet.

anyways, i might make the lower outta brass and aluminum plate it, or something, (reminder, check plating values) and if i can that should save on recoil, not that i think this thing needs it. We'll cross that road after the next con. 

So i guess the next step will be to fit and finish the rest of the body, my question is, should I make the trigger cast into the gun? there will be a lot of those kinda questions in the near future i can assure you that. I think the next thing i need to do is make the rotocasting machine and play some more reach. OOH! TV's I need to get the new tv in. And the shelves. that would be good. anyways, I'm rambling and i gotta get stuff done around here. See you soon.

A Marine's Best Friend

I'm building another Space Gun. Because Space Gun. Last night I started the construction of the Misrah M6G Magnum. I'm still working out what the real world caliber will be, but for now it'll be Lithium Ion. It's no real secret that my Halo will always be Reach, and that drives the majority of my creation's decisions. Once I settled on a generation and style, I found a Thingiverse model (because c'mon, there's no way there's no thingiverse model) and started printing the trigger alongside some prototypes for another project. 

So far, so good! I laid out the pieces that would fit on the build plate of the small printer, as I'll be making a couple of different molds for this as time goes on. One of which I would like to be static, maybe with a trigger pull, but I'm not sure. I wouldn't mind having a couple of giveaway castings for people who just need one for the con or whatnot. 

Anyways, I'll definitely be printing this all weekend long, and I suspect I could do it all in one go on the larger printer... Regardless, I should have the laser and slide done by actually close to the time of penning this. There are a couple of other bits and baubles I need to print next on it. 

After some google searching I found out that a 50 AE round will be accurate enough and makes me wonder about what the hell kinda marines we're sending to space. I've personally never fired a 50 caliber anything, though I'm not sure how shotgun slugs compare.  After some initial (and albeit sparse) research, it would appear that the only sizes available for this are 7 and 10 round magazines. The good thing is that either option, in Desert Eagle format is available for not much money. My initial idea is to have two magazines that are in reality battery packs. I'm thinking I'll have two terminals in the first round position, and have the charger in between them. Nothing too fancy here, but it will mean the solenoid won't work without the magazine fully inserted. 

I have also ascertained that the initial idea of using 18650 cells will not work in a stock magazine.  I'll have to find another solution then...
