skARpion vz61 - partitioned prototype - part 2

Finished basic partitioning of VZ61.  Ugly, but there it is.  There are four connecting sidewalls (one on each side, purple, red and teal pieces in the pictures below) which can be printed flat without supports.  The rear buffer (yellow) can be printed on its backside without supports.  I think the front piece can be printed without supports.  Middle piece (green) is complex and definitely needs support and should be printed upright.  The grip piece (blue) should slide in upward and will be pinned in place.

Untested; not ready for distribution just yet.  Soon, though (this year, sometime).

To do:

• Round out the rear connecting walls a little bit to be aesthetic and add material around screw holes
• Make the rear connecting wall follow the angled contour of the middle piece and mag well area.
• Triggergaurd - a single 3d printable one or an AR15 triggergaurd adapter
• Add pin holes on grip mount
• Add an optional buffer tube adapter
• Alternative versions for an AK grip or my custom MG42-styled grip.

Part one

WIP: AR + vz61 Skorpion hybrid - "The SkARpion" - part 1

Work in progress for a 3d printable VZ-61 that uses an AR15 FCG and is printed in small sections.  "SkARpion?"  Pretty terrible name, I know.  This design is based on FreeMenDontAsk's design which you can find on DefCad.  It used to be available on GrabCad but I guess it got deleted by moderators.

Initial partitioning.

I personally hate 20+ hour long prints and want to print the pieces in smaller, easier to manage sections.  This way I can tune the receiver to my printer/filament and not have to re-print the entire thing if something is screwy.  Also people with small print beds would hopefully appreciate this.

The front and back pieces should not require any supports.  The middle one will probably need support on the bottom.  The slightly clear green wall is one of the connector pieces that will have holes that will screw all the way through to the other side of the receiver.

Not really high on my list of priorities, but I wanted to show a proof of concept.

Progress report: Magazine walls done.  Walls should not need supports.

Laminated gun parts

This week on Ghetto Gunsmithing - a laminated gun part.  I saw this on ebay.  The seller says it's a Colt, but looks like a homemade replacement for a .22 single action of some sort.  But it is still interesting, nevertheless.  Instead of machining it with a milling machine, the part could be cut out with a jigsaw and welded or screwed together; perhaps the individual sheet is filed down to fit before final lamination.

Builders on weaponsguild have been using the laminated design for gun parts with success already - so if it works, go for it, I say.

Swing-out action, single barrel shotgun

Saw this auction for an odd .410" shotgun barrel on ebay.  It didn't have a hinge point like usual single-shot, break-open weapons, so I was tempted to buy it because of how unusual it is, but I don't really have the time for another project.

The barrel is from a Firearms International model Garcia Bronco, .410".  Sometimes these skeletonized weapons were known as "bicycle guns," because they could be folded up and stored underneath a bicycle's frame.  The barrel rotates like a modern swing-out revolver.  The barrel appears to be held in place to the rotating sleeve assembly by two pins, but there must be more to it than that?  Perhaps it's pressed in or threaded in?  One flaw I could possibly see in this rotating action is that everything seems to be hanging on a relatively thin solid rod which is also used as the axis of rotation - what would happen if that bent?

It's not really as rare as I had thought because people are finding this thing in pawn shops for less than $100.  The simplicity of the action makes this seem like it would be easy to replicate with simple tools.  Gun Parts Corp is also selling parts for the combo gun.  Chiefly, the barrel sleeve and breach block are relevant to my interests.

AR15/1919 hybrid thing

I've been messing around in CAD software and I recreated parts of a Browning 1919 and an AR15.  My idea is to create an unholy union between the two.  Basically it's a heavy-metal receiver shell that you can attach an AR15 upper to and it uses an AR FCG, but it handles like a Browning 1919, complete with spade grips and can be mounted onto an M2/M3 tripod or a standard vehicle mount.  There wouldn't be any real purpose for this, but I'd like to put a FM-9 9mm belt-fed upper on it, or a Fightlite Industries MCR.  Basically the fun of owning a Browning 1919 but with cheap ammo.

A flat-based AR receiver in progress.

Browning 1919-like receiver with an AR15 upper.

The extension below the bottom plate is a protective housing for the AR15 fire control group.  I could have just cut the finger off and avoided that unsightly extension, HOWEVER, I wanted to be able to use off-the-shelf FCG units such as the Fostech Echo Trigger without having to modify it.

Saw this on eBay.  A cut-away of the breach-end of a rifle barrel.  It's interesting that the threads do not seem to cut that deep and only go in about 3/4" into the barrel.

Treasures of Round Top Fair (with photos)

Took a trip to Roundtop Fair a few weekends ago, near Lost Pines, Texas.  One of the nation's biggest gathering of vendors for the biggest garage sale/antique show, held bi-anually.  The actual event is held within a 10 mile radius of Roundtop, specifically Warrenton.  You can go to the surrounding towns and they'll have even more groups of vendors selling stuff.

Warrenton is where the biggest gathering of Vendors are located.  In Warrenton, within ten minutes I found a tent with all sorts of guns being sold by a retired gentleman.  He was there with his wife, who I suspect was forcing him to liquidate his collection.  In the center of the tent was a table which held some M1 Garands, 1903 Springfields, M1 Carbines, Krags, Mausers, fancy muzzleloading flinchlocks, a few modern wood-stocked sporting rifles, and a glass case full of overpriced .32 pistols and breaktop revolvers and a few Smith and Wesson revolvers.  There was a singleshot Gewehr 1871 for $200 in good condition that was tempting me, but I knew better than to buy an obscure blackpowder rifle in an obscure caliber that costs $5 a round.  Basically standard Old-Guy weaponry, nothing that interested me.  In the surrounding tables were random antique stuff.  Boxes of skeleton keys, a lone French Berthier bolt missing the bolthead, spurs, pieces of furniture, picture frames, and kitchenware.

Lifesize T-800 statue for $1000
What a deal!

Several umbrella bins on the ground held a bunch of rusted toy rifles and some de-activated guns.  Single shot shotguns, .22 bolt actions of unknown make missing parts, a Spencer carbine with the barrel chopped and a rod welded in the chamber, and a late-war Arisaka Type 99, with it's bright red stock and a stripped bolt duct-taped around the receiver.  It was missing a bunch of parts and the stock had been chopped at the band.  I don't particularly care about Japanese, Italian and French rifles and I promised myself I would never own these guns just because they are chambered in weird, obscure cartridges, and on top of that, I don't like adding more calibers to my collection.  However, I could not go home empty-handed!  I removed the bolt and peaked down the bore.  The chamber was intact and rifling visible.  I asked him how much and he said $20.  I took it.

I should have offered $15, but whatever.  I have a complete spare bolt and a bin of parts at home I could probably partially restore it with, and I have a chopped fore-end from an Enfield that I could hack onto the Arisaka somehow.  I could probably make my money back by selling the extra stripped bolt on ebay, although I probably will spend as much money as a complete Type 99 trying to restore this thing.

I actually ran across two more Arisaka Type 99's at the show.  One was crudely nailed to a 2x6 pine plaque, though otherwise good-looking.  The other was in worse shape than the one I paid for, but complete.

Traveling from Warrenton to Roundtop there are a bunch of tent cities and barns with vendors selling stuff.  Warrenton is a good place to go for random antique junk and I think we spent about three hours just walking through there browsing.  Near the end of Warrenton tent city is Cole's building, with more fancier stuff - real antique furniture, and at least six gun dealers with nice antique rifles, shotguns, muzzleloaders, and other pieces of militaria.  I recommend bringing at least $300 if you're serious about buying something here.

We stopped at a barn near Roundtop, where there was a ton of cowboy stuff.  Holsters, boots, spurs, revolvers, amongst other random junk being sold by women - kitchenware, plates, jewelry, clothing.  Is that sexist?  I can't help it if that's what they were selling!  I spotted a half scale Colt 1851 Navy in .22 cap and ball for $400.  I'd never heard of or seen one and a quick google search doesn't reveal much about it, but I saw something similar being sold at Cabelas in their firearms display room for the same price, so it couldn't have been too rare.

Outside the barn was a man who told us he came all the way from Missouri just to sell stuff there.  He was selling a bunch of surplus ammo cans, crates, wooden dummy rounds from navy guns, green Sea-Bags (I guess army people call them "duffle bags", how odd!), and other stuff.  I spotted an ammo crate for $20 and knew it was a good deal so I took it.  Inside was a short length of thick docking rope and an old antique bubble level.  The wood of the level was moldy, but the bubble level still intact.  I figured that was worth the $20 and the crate could be used to store my ammo.

Next, a few miles up the road at one of the smaller barns/vendor gathering, we spotted a wood box.  Inside was a bunch of mementos, medals, a letter, and newspaper clippings from a Hospital Corpsman Fred L. Martin during World War I.  Interesting I guess.  The box is nice too.

All in all, Roundtop fair is a great place to waste money - highly recommended!  Pics of loot, click to enlarge:

Photos: Rusty old broomhandle (and a gewehr 88)

Old pictures from 2012 that I never uploaded when I migrated this blog from WordPress.  This was taken after the last post where I foolishly neglected it. It's all cleaned up now. It still shoots and functions fine. Also pictured: A Bulgarian WW2 helmet and a Gewehr 1888 Commission Rifle that I paid 20 bucks from Old Western Scrounger back in 2004.  Photographed on a cheap Kodak pocket cam.

The Elusive Star Model A Pistola

Ever since I bought my first Mauser Broomhandle back in 2009, I've had a weird obsession with all things 7.63 Mauser.  Specifically, it was the Star Model A that caught my eye.  Maybe it's the neat cartridge it comes chambered in, or maybe it's the Colt 1911-like ergonomics, but I just always wanted one.  Plus I always had a thing for a pistol with a shoulder stock.  Since 2009 I've been using GunAuction's "Auction Recon" feature to alert me in the event that a Model A should show up for sale, but I haven't found a single one yet.  I wasn't really serious about buying one at that point anyways.

YOINK'd!

Last year I happened across a mysterious combination shoulder-stock/wood holster for a mere $75.  I bought it on a whim and discovered it was actually a rare Star Model A shoulder stock - it was fate!  I knew at that point I needed a Star Model A to help complete my collection of NFA-exempt stocked pistols.

I've been searching for a Star Model A Pistola or Carbine more rigorously since.  Either one, any one, chambered in 9mm, 9mm Largo, or 7.63 Mauser, with or without tangent sights.  I see these selling on GunBroker for $1300 for a well-used specimen, and up to $3000-$4000 for a pistol in 95% condition, with or without the shoulder stock, but I'm not willing to pay that much.  Since GunBroker doesn't keep records of old sales, I did a price comparison on GunAuction and it seems that these guns sold for well under $400 ten years ago.  I wonder what changed?

More recently I came across a seller on eBay who was selling a slide and some small pieces of a Star Model A.  I inquired about the frame and managed to talk him into selling the frame and slide to me.  The whole lot was soon transferred home to Texas where it belongs.

 

Disregard that pin thingy on the right.

I'm not sure how I'm going to go about fixing it.  I already knew that parts would be impossible to find for this.  I've been told that cheap surplus Star Model B parts are compatible with the Model A.  I already have most of the major components, so all I would really need is the recoil spring assembly, the safety and slide release, magazine, hammer spring, and barrel.  I think sacrificing a Model B to save a Model A is a fair trade.

The grip panels I believe are the same as a model B.  It's just flat-shaped wood that's slapped on there and held in place with two screws, right?  As for the barrel, a Model B barrel (if it actually fits) can be bored through, relined to.308, and rechambered for 7.63 Mauser.  Pretty sure I'm never going to run across a rear ladder sight by itself, like, ever, so my only hope for that is to just find a complete slide assembly on ebay and part that out.

Yoink'd again!

Bonus:  I recently tracked down a much nicer shoulder stock which I estimate to be in 95% condition (in my non-expert opinion).  It looks pretty new.  As far as I know, the Chinese (nor anyone else, for that matter) didn't manufacture copies of these like they do with Broomhandle, Luger and HiPower stocks, so I'm pretty certain this is original.  The seller is from Spain and doesn't even English, so I dunno if I just spent $100 on a screw or an actual complete stock, but to the left is a picture of what I believe I just purchased, so I'll just have to wait and see if it actually arrives!

  It's also interesting to note how very little information, pictures or video there are out there on these weapons.  Sure, there are a few pictures of a Star MMS and Star Machine Pistol, but below is the only example of a complete Star Model A with shoulder stock and rear tangent sight I could find.

This is what it should look like when it's all said and done.

American Pioneer and Corrosion (Broomhandle Part 2)

See my initial rusty C96 Broomhandle purchase here.

Somehow lost track of documentation of restoration progress, but the TL;DR of it was that I scrubbed at it with some steel wool and mineral spirits, cleaned with a dry cloth, applied Casey's cold blue and re-oiled.  I replaced the grip with a $30 red wood grip from India.  Looked good enough to me.

 Here is the result of shooting about fifty rounds of American Pioneer blackpowder substitute through a Mauser Broomhandle for the giggles and forgetting about it for a year just to see what would happen.  American Pioneer is a black powder substitute that is said to be cleaner burning and less corrosive than black powder.

Addendum: This experiment wasn't really trying to prove anything except that I'm lazy.  I still prefer American Pioneer over black powder just because it's easier to clean.  I just never realized that it would get this bad.  I pretty much never clean any of my guns unless I have to.  Used steel wool and oil to clean up the light rust again.  Looks about as good as it will ever get.

Video - Springfield Trapdoor backfire

I thought this should get more attention from Trapdoor owners out there, like me, who reload.  You can see the breachblock fly open and the spent casing jump out.  Not quite as catastrophic as a real 'kaboom,' but I always imagined the shell would go flying backwards like a rocket in such a scenario.  Since the video poster didn't respond to comments I can only guess that he was shooting smokeless rounds reloaded hot.


...And starting now I'll never shoot smokeless through my Trapdoor again!

Cheap 9mm Magwell Adapter (plus mini review)

Just a heads up that Sportsman's Guide is selling 9mm Magwell adapters for cheap. It's made by Promag (I know, bad reputation), but it seems just as good as any other plastic magwell adapter that sell for $100-$150.  The ejector, ramp, and bolt hold-open are steel.  It accepts regular 9mm magazines (including modified UZI mags, but those don't have bolt hold-opens).  When I first got it, case mouths were getting caught on the sharp edges, but some minor hand filing fixed that.  One important thing should be noted about this is that it drops from the top of the lower and requires removal (and re-insertion) of the AR-15's bolt hold-open, so don't expect to be switching between calibers too often.  Actually, I don't even use the bolt hold-open, so I just removed it completely so I can switch out uppers quickly if I want.

TL;DR - if you have a spare lower lying around, this is a great way to get started into 9mm AR15s.

Photos - $250 Mauser Broomhandles!

There was this company on AuctionArms called OysterBay Industries (their screen name was OBI or something) and apparently years ago they were an importer of Broomhandles and they made detachable magazines for Broomhandles (and modified their frames).  I bought this one for $250.  It looked okay in the pictures, but was worse in person.  I still think it's shootable, though!

  I began by removing the grips.  They were crusty and disintegrated immediately.  The grip frame was pretty nasty with heavy pitting.  I'm surprised how thin they are.  I feel like they would break off if I dropped the gun.  Actually that would be kinda neat if I could replace the grips with an AR-15 pistol grip.  Next I stripped the 'upper' from the grip frame (the barrel and upper receiver are actually one piece and cannot be separated)  I didn't wanna take apart the fire control group just yet, because I was afraid they would break or I'd loose some pieces.  I let the metal parts soak in brake cleaner for a few days.

To be continued in part two here with video footage.

AR-15 Finished

Last time on AR15-Z!

Here's the AR-15.  Parts rundown:

• .223 bull barrel 24" - $200
• DPMS Bolt+Carrier+Charge handle - ~$150
• Del-Ton Lower - $225 (yes, I paid that much, dammit!)
• DPMS (and some Olympic parts) Lower Parts - ~$70
• DPMS Upper + Parts  - $145
• Float Tube - $50
• A1 Butt Stock - $30

Total - $870.  Not exactly saving money by building your own rifle during the current situation, but at least I learned how the thing functions.  I don't think it was possible to buy a complete rifle for less than $600 in the past nine months but that's how much much a mix-'n-match like this is supposed to sell for.   The 14X Scope (BSA) and Riser+5" Extension (Yankee Hill Machinery) cost $35 and $20 and I already had these two lying around so I didn't factor them into the total cost. I haven't had a chance to fire it and I don't think I want to.  I think I may end up selling the upper since I already have a nice .223 T/C Contender Carbine.  I didn't realize I wasted so much money on this 'till JUST NOW.

Hunting at Escondido Ranch

We went hunting for the first time.  Went to a lodge called Escondido Ranch, which is owned by the Navy and run by the 'Morale Welfare and Recreation' department.  When we got there, there were three enlisted navy personal running the place and one elderly gentleman chilling in the lounge watching some Clint Eastwood movies.

After registration, they told us a bunch of rules.  One shot one kill, no followup shots, no execution shots.  No firing at anything except hogs.  No wandering from the stand and hunting Elmer Fudd style.  They said if we saw a mountain lion we should kill it because the XO wanted it.  We headed to the range to register our guns and make sure we were proficient with our rifles.  Also, apparently we should have had scoped rifles but didn't.  We were using iron sights.  Come to think of it, we don't own any scoped rifles.  I thought all of those things were odd, but whatever.

This is what most of the roads look like

I brought my new and mint 1953 Mosin Nagant with surplus ammo and my dad used his Savage 340A in 30-30 Winchester.  The gong was 50 yards away and we had to hit it three out of five times.  I never realized we had to qualify to hunt, so this seemed strange to me.  I never fired my rifle before, so I was kind of nervous and flinchy when I fired, after all, I'm always hearing stories about surplus rifles and KABOOMS and I had this rifle that I'd never fired before.  They asked me what kind of rifle I was using and told them it was a Mosin Nagant.  They had puzzled looks as if they never heard of it before.  Maybe they haven't.  Hell, they even reloaded. I expect everyone who reloads should know these basic guns.

My dad shootin' a Noisy Magnet

I don't think me and my dad hit the gong but they let us hunt anyways since we paid the fees and registered and everything.  If I did hit the gong, I wondered if the bullets pierced right through?  These were FMJ bullets with steel cores, and I imagine most hunters would have used soft-nosed lead bullets.

A whole lot of nothin'

They took us about four miles into the middle of nowhere.  They gave us a radio and told us goodluck, have fun, call us when you're done.  We spent about three hours in and around the hunting stand before getting bored.  We saw a bunch of deer and some rabbits, but no hogs or mountain lions.  At sunset requested pickup over the radio.

My dad firing our .22 Marlin 795

I had fun, my dad didn't.  I wished I could have killed something.  We went back to the range the next day to use up our ammo.  The range was pretty clean.  Every piece of brass had been picked up.  We went last year, but couldn't hunt that time because we came on the wrong day, but they let us use the range and there was a ton of brass we picked up.

My Mosin Nagant and the approximate distance of the gong.

Five shots at a gong-sized paper.  No way I could have missed!

I wanna go on the all-night hunts next time, without my dad.  He hates guns and hunting, but this was his idea after all.  What a sweet job that is, running that ranch.  That has to be the best job in the Navy.
