Conjectural "Hero" Merr-Sonn Model 44/Power 5

Starting an actual thread rather than continue to clutter up the Hero DL-44 thread. I say "conjectural", as the Imperial Mauser-based blasters were cast dummies with fairly simple greebling -- basically the province of Stunt props. As I started on my build, one thing and another I kept wanting to do "better" than it looked on those props, and I realized I was building a Hero. Which makes sense, as all my costume and prop projects I want to be able to stand up to scrutiny at close range, which Stunt-finished items tend not to. But since there was no Hero version of this/these blaster(s) made, I'm doing my best to extrapolate finish and detailing while remaining true to the essence of what we see in the photos.

Thanks beyond expression go to jheilman, for upgrading to an MGC and selling me his partially-modded Denix; to Dark Energy Creations, for having a couple leftover parts from his earlier DL-44 parts kit run (since I didn't need the whole kit -- just flash hider with no holes, booster, and bull barrel... which he ran across and offered me); to deadbolt, for all his research into Han's Hero blaster, the revelations to the identities of some of the parts, and for making highly-accurate 3D-printed replicas available on Shapeways; to lonepigeon, for the Parts of Star Wars site and all his ongoing research into what everything is, which pointed me in a more accurate direction for the "scope" thingie; and to all the participants in the ANH Hero DL-44 discussion thread.

So. Here's what I'm starting from. The "Model 44":

...and the "Power 5":

Because of all the digging into minutiæ in that thread, the real-world history of this blaster is related to Han's DL-44. There's a gunmaker in London who makes (or at least made) specialized firearms for various film and TV productions in the UK. These included at least three Mauser C96s modified in similar ways. They went through pieces of them when working out Han's blaster. They were quite probably most of the way there when they cast the Imperial blasters, but then used a different lower frame and chopped the bull barrel down further for the final version of Han's blaster. There's also a circular raised detail on this blaster on the left side of the frame toward the back. That's the remains of one of the scope mounts one particular modded Mauser had. The other is hidden by the Imperial disc greeblie on the magazine.

For the "Model 44" version, the propmakers snapped off the flash hider. The flash hider assembly was probably cast as a single piece and then glued onto the end of the bull barrel. The undercut into the muzzle would be too much for many moulds to handle. I said "snapped off" above because the ragged end of the Model 44's barrel implies something was glued to it and then forced off -- the resin snapping before the glue bond did. It also appears that the T-track and pushrods were glued onto each after casting, as the "iron sights" on the Model 44 are significantly shorter than on the Power 5 (though still much, much longer than those on the DL-44).

In-universe, the story is essentially that BlasTech made the DL-44 hoping for a military contract (as arms manufacturers all want). The Empire took one to Merr-Sonn and said "can you do this cheaper?". The result was Merr-Sonn's "Model 44". Imperial procurement noted the obvious lack of booster/flash-hider assembly and asked if it was as powerful as BlasTech's version. Merr-Sonn said, "*shrug* Yeah, pretty much". And were told they were supposed to do better than "pretty much". And the result was the "Power 5" version. The Merr-Sonn has a different heat-dissipation setup, with the heat sinks along the rail between upper and lower parts of the frame instead of on the front of the magazine box. The bull barrel is longer on the Merr-Sonn, which means the flash hider sits further forward. This also leaves more room for the "iron sights" along the top of the bull barrel. The detailing on the lower frame of the gun is different, too. And, of course, the DL-44 has the big scope and mounting rail, where the Merr-Sonns both have that plug acting as targeting optics.

Me being me, I'm making a stupidly over-engineered version of both blasters in one.

I'm making the Power 5, from which I can remove the booster/hider assembly and the greeblie on the right side of the magazine box to turn it into a Model 44. I'm treating the other minor differences as ignorable -- the different lengths of the iron sights, and the lesser detailing on the Model 44's magazine box. I'll address all that greebling as I get to it. Next up: starting point...

The Denix, as many know, is not the best Mauser replica out there, but it's not expensive, and I feel a lot less bad about chopping into it than into a rare MGC or real Mauser. jheilman had already done a lot of prelim work on his Denix when he sold it to me. I need to tweak a couple things on the frame, but th ereceiver and bolt still need a lot of work. Here's a side-by-side with my real Mauser:

It's slow going with Dremel and files. I don't want to take off too much. I'm going to start on the stuff I'm adding in another post...

Okay, working from front to back...

I got incredibly lucky on barrel stuff, as I hinted at above. I found out about the deadbolt/Dark Energy Creations run of kits for modding Mausers (or replicas) into the Hero ANH DL-44 significantly after the fact. Which was largely fine, as I have no need for the scope or scope mounting frame or heat sink. But I did want the barrel stuff. And as I was going about figuring out how I was going to scratch-build or source the bull barrel, recoil booster, and flash hider myself, DEC e-mailed me out of the blue and said that he'd found a few leftover bits from the original run that hadn't had the rest of the parts made to turn into kits. So I got the separate bull barrel and recoil booster I needed, and a flash hider with no holes drilled, which was also how I needed it. If you look in the pictures of the Power 5 in the first post, you see some depressions where the holes showed up in the mould, but not all the holes were caught, and none of them were drilled out. So I'm going with a smooth flash hider.

Here they all are. I apologize for the blurry. My old camera died and this one doesn't let me tell it what I'm trying to focus on. I'm still learning how to trick it into doing what I want it to do.

Bull barrel:

Recoil booster:

Flash hider:

DSC00251_zpse52b62c3.jpg


Back of the flash hider is the iron sight. This was made from the ubiquitous cabinet door T-track that was used on so many things in the Original Trilogy:

DSC00259_zps729ba490.jpg


The bottom of it got ground away so it's just the vertical part:

DSC00262_zps8e6b2c22.jpg


That gets glued to the top of the bull barrel just in front of the chamfers where it meets the breech, approximately like so:

DSC00264_zpsf3159f5a.jpg


I ran into an annoying delay when I took the bull barrel and flash hider in to get them anodized. The purchase order didn't specify a color, even though I'd said black, so they got anodized clear and I had to have them redone. :facepalm Just picked them up Monday, and here they are:

Beauty, eh? :) Moving down to the frame now...

Back at the butt of the gun, now... Instead of just the raw cut-off post the original prop had, I decided to make that bit appear intentional and functional. So I chopped an "adjustment knob" off a cheap plastic scope I got at Goodwill for fifty cents and used it, since it's the same diameter:

DSC00266_zps363a3a52.jpg


And moving down, I decided to skip the regular wood grips, since the prop was just painted solid black. Mauser made several optional-upgrade monogrammed grips out of "guttapercha" (phenolic resin), and I snagged a set of replicas off of eBay:

DSC00156_zpsf47b3f5f.jpg


I like that they're already black, and I like the grip texture. I'm going to grind the flowery "WM" (for Waffenfabrik Mauser) down flat and set an Imperial cog in there. I still have to do a bit of work on the frame to make them fit right, but not too much:

DSC00152_zps62215df7.jpg

DSC00153_zps83738b27.jpg


Since there's so much of it, I'm going to start on the fiddly stuff in another post...

Staying on the frame for a little longer, I'm tackling the disc. My first instinct was one of Elvistrooper's machined replicas, but when I sited it, it was visibly too big. So back to the pictures and a lot of measuring and math later, I'd photoscaled the disc on the prop to be about an eighth of an inch smaller than the ones on the Imperial officers' uniforms. Since as far as I know, Mitchell didn't make a slightly scaled-down pulley, my theory is that, while they used the more inert moulding and casting media for the base blaster (the ones that don't shrink as they cure), they used castings of a Mitchell pulley instead of the real deal to deco these blasters, and the materials they'd used for them did shrink.

So, since I have more time than money or tools, I tackled replicating it out of hardware. Specifically, 3/4" PVC conduit (o.d. of ~7/8") and a bunch of brass tubing in successively narrower diameters. Outer ring:

02c1-Discgreeblieoutertier_zpsd79d1993.jpg


Mid ring:

02c2-Discgreeblie-middletier_zpse075c4e1.jpg


Here it is side-by-side with the ET disc:

DSC00301_zps9e5e76d4.jpg


...and in place on the blaster:

04c-Discgreeblie_zps51bed5ba.jpg


The distances with the scratch-built disc -- back edge of disc to front edge of milled inset in frame, for instance -- match pretty much dead-on.

So, since I'm a diva with brass tubing, I decided to tackle the adapter that sockets into the recoil booster to mate it to the bull barrel, using the set-screws at both ends to hold it in place. Here's what I started with:

06a-Adapterexplodedview_zpsff0579a3.jpg


The bull barrel end of the main assembly, minus adapter projection:

06b1-Adapterbreechend_zps9a95b6a4.jpg


...and the muzzle end, minus barrel tip:

06b4-Adaptermuzzleend_zps5267819c.jpg


That sleeve is the bit that fits snugly into the narrow end of the booster, that the flash hider set-screw bottoms against. The next couple came out blurry and I need to re-shoot, but here are the barrel tip:

06b5-Adaptermuzzle_zps66df0ddc.jpg


...adapter collar that fits snugly into the bull barrel, that its set-screws bottom against:

06b2-Adapterbarrelfitting_zpsa17451d6.jpg


...and the bolt splitter that sits down inside that bit (a smaller version of how the Death Star superlaser works -- the bolt gets split, each bit amplified, and those elements re-collimated into a more powerful bolt):

06b3-Adapterboltsplitter_zpsab6d1eca.jpg


I'll re-shoot those, and take a couple of the whole thing rough-assembled, on its own and in place, this evening. I also need to take a few more shots of my progress on scratch-building the scope, which will comprise an entire post of its own. I have the replica pushrods for the iron sights, and am expecting the engine cylinder halves soon. A lot of finishing and painting work will be required before final assembly. In the meantime, I keep working on cleaning up the Denix. *heh* As a "mid-stream" referent, here's a mock-up of where things are right now:

Wow, looking really good so far

working on a Merr Sonn myself but I think you're going to be going a step beyond :)

very cool
 
I like where you're going with your builds, too. You ran into the same problems I did. Want me to send you scratch-built "mini-disc" and scope assembly? I have enough of the raw materials on hand. Since the stuff I have is in inches, and UK stuff tends to be metric, I think you could get closer to accurate with what I've sourced, ironically enough.

For what it's worth, the exposed portion of bull barrel -- from the breech end to where it disappears into the flash hider is right around 50mm. The pushrods are a couple millimetres shy of that, but they end right before the chamfers, and have a slight gap between the heads and the flash hider. I have the base-less T-track go right up to the flash hider, and cut it at the back right at the chamfer.

I also have my unused scratch-built bull barrel, abandoned partway in when I got the aluminum one:

DSC00135_zps6a4df0cb.jpg


It's 3/4" PVC pipe that I fattened up very slightly at the breech end and ground down very slightly at the muzzle end. I'll take a pic of it side-by-side with my aluminum one tonight -- they're nearly identical. I hadn't ground the bottom flat yet, or cut in the chamfers, but it's already got the taper locked in... I have no use for it now, and it'd be nice if it could find a home with someone who'd put it to use.

Took the pictures a couple days ago, but life has kept me running around enough that I only now finally have time to upload them here. Yeesh. Anyhoo, those clearer pictures I promised:

With the recoil booster fitted over:

While I'm not going to glue it in place, I do intend the whole assembly to be "really" one piece in-universe. Here's how it looks all together (bearing in mind, the next step is blackening the steel and brass):

Figure of speech. : P As I am neither female, nor a singer. I like to think I can do pretty well with a pile of K&S tubing, though. ;)

--Jonah
 
***Guys. Www.shapeways.com carries a COMPLETE plastic 3d printed "kit" of merr sonn 5 pieces to convert a c96 mauser to a merr-sonn 5. Forgot the price but couldn't believe it. Look under "star wars" or " "greeblies for gooks" just wanted to help. Also the top coil I am using in my build is from office Depot as a pen holder coil (like they use for secure bank pens.) Only $6.00

steeljurist
 
About all I'd want from that conversion kit is one of the right-side greeblies for the magazine box. I either already have the rest, am getting original parts, or my scratch-made replicas are more accurate. For instance, that scope-plug-thing is visibly off, even without comparing, and it looks like the disc is the standard ~1" diameter, which is too big for the one on this blaster.

The wire for the scope, by the way, is 3/16" thick, so unless you got a really beefy pen-keeper cord... ;)

--Jonah
 
This is incredible, I'll be following!

Is that real T-Track? looks like Marv's lol if not, where'd you find it!?
 
Regarding the scope wire: I used 1/8" clear tubing I got by the foot at my local Ace Hardware. It's meant to feed a low-flow water line, made of vinyl. I ran eighth-inch aluminum armature wire through it, heated it mildly with a heat gun on low, and wound it around a 1/4" brass tube (since that's the inner diameter of the coil). The rest is then just stretching it very slightly so there's gap between the coils, bending the end that fits in the firing pin hole, measuring along the top of the blaster... and it's easier to show attachment method with pictures. That'll all be coming this week.

As for the T-track, yep it's Marv's. :D Well spotted. I'm not doing lightsabers, so I don't need the width of Gino's. I ground the base of this bit off entirely, and the only other thing I'm doing with it is an ROTJ EE-3, and he sourced his off those, so I'm golden. *heh*

--Jonah
 
I have always maintained that the "Model 44" does not deserve its own classification. It's just a prop that used to be identical to the "power 5" but is broken. Possibly when the control room guard slammed to the deck after Han shot him.

Anyway, great thread and great build!
 
That's pretty much why I took the approach I did. I like the in-universe origin that I paraphrased in my first post. :) It does make sense to me to represent both as one, with an additional (removable?) booster. I intend to use the "Power 5" version as an Officer sidearm, and the "Model 44" version as the off-hand blaster for my Storm Commando. When all one needs to do to change it over is three set-screws and a plugged-in greeblie... *shrug* Almost as easy as a supressor, and not without real-world precedent.
