    Joining my (badly in need of updating) Merr-Sonn build and my custom Westar-34 build is this newcomer to my stable. Some may already know it from the five seconds it was available online before the mad frenzy wiped out everyone who had them stocked. :p I managed to score a few for myself and a couple other folks.

    So this is what I started with:

    [​IMG]

    All the Margolin parts are dead-on. The Veyron Tomtit model radial engine cylinder bit is loosely accurate -- the distance from front fin to back fin is correct, the number of fins is correct, but the spacing is off, the tail end is too long, and the part inside the fins is supposed to step down from a larger cylinder to a smaller, rather than tapering like it does here. And the coil bit is the wrong length and diameter and number of coils.

    So, as is my wont, I did some careful butchery. :D After taking measurements, the barrel went bye-bye...

    [​IMG]

    ...the sight mount got carefully removed (and is most of the way though cleanup and prep)...

    [​IMG]

    ...and I hollowed out the muzzle brake to get rid of the post that was helping join the two halves just inside the barrel opening (also, said opening is slightly to small). I filled most of the compensator with plumbers' two-part epoxy putty, cut in the vent before it set up, and have drilled out a pilot hole along the bore (need to get it to a drill press to drill out the barrel bore). Still some other cleanup left here, too.

    [​IMG]

    Now, on to construction... As I've said elsewhere, I like to think of myself as a bit of a virtuoso with K&S brass tubing. Here are all the parts for the build (except for the coil) laid out:

    [​IMG]

    ...and with the different subassemblies started:

    [​IMG]

    At the top, that's a 1/4" brass tube, the inner diameter of which is the right size for a Margolin's bore. I'm using that for the spine of the barrel. Below that, from the muzzle back, the aforementioned modded compensator, one of the original Tomtit engine cylinders, the "plug" that slips down that central tube to help lock those pieces together and keep the barrel centered, then the substrate for the coil -- the rearward projection of which the sight slides onto, the sight, the next bit of tubing locks the sight up against the forward barrel, then the next plug for the main barrel, then the main barrel, then the rearward projection for it, which goes on last and will help anchor the barrel into the breech, with the help of more epoxy putty.

    Now I need to sort out the coil and continue cleanup...

    I'll be watching as I want to see if I can get any ideas for my mod.

    Currently, I am thinking of cutting the barrel at the point between the coil and the front sight. I want to enforce the entire barrel with metal rod or tube and then have it extend out to use as the base for my add on coil, grill, and muzzle.

    Like you, I also have the tomtit part. I am thinking of getting a 3D printed muzzle from shapeways.

    Let me know if you find a good cord for the coil.

    The muzzle that is part of the toy is pretty much perfect in dimensions and durability. I removed that post and the molded in notch, and the glue holding the halves together hasn't even twitched.

    Reason I scrapped the entire barrel is I wanted to ensure roundness and not have to fiddle with smoothing the seamline. Also, so that the forward extension was the same diameter as the rest of it.

    Very cool...watching your progress with great interest

    Frank: You´ll be getting a resin cast of an actual muzzle along with your kit. You´d have to file out the slot and drill a hole, but it´s still better than a 3D printed part IMHO ;)

    Yesterday evening I snagged a power cord to connect a Jackrabbit battery pack to some flavor of a/v equipment for 99 cents at Goodwill. One of these:

    [​IMG]

    Which is nice, because it retails for $70.

    Now, since making this blaster and using some for the scope-thingie on my Merr-Sonn build will use up a quarter of this cord, I can get four or five more Defenders' worth of lengths out of this cord if anyone wants them. Markus, Paul, Frank -- I'm giving you guys first dibs.

    Now to see what I can get done today...

    I might take you up on that. I was just at my local goodwill and I saw a coiled car cord for an iPhone for $1. I am going back to take a look because i wanted to a measurement on the cord before buying it.

    Yep, got it today. It is a nice cast. Drilling the hole... can do. File... do you think my wife's pedicure file will work? :p

    Going to want it to be within shouting distance of 3/16" thick, regardless of coil size.

    Just an addendum to mention the tubing I used is 9/16" for the barrel segments, stepped down in 1/32" increments to 1/4". For the bit that seats in the narrow end of the engine cylinder, it's stepped up two layers, even with the part end. Also, not shown was the slightly trimmed-down 1/2" CPVC pipe coupling that I use to join the muzzle piece to the engine cylinder.

    Why are these suddenly so hard to come by? It seems they went under the radar for a while and then within the last week or so, poof, all gone. Aside for there being a mad run on them, did Rubie's pull the product?

    I don't want to this thread away from Jonah's build, but we are discussing such info here: http://www.therpf.com/showthread.php?t=241937


    @Jonah, what size tube/rod would I need to fit down the existing barrel. I would want it to slide in easily,

    You're cutting it off just past the sight, right? Getting rid of the inaccurate coils and engine cylinder, and using Markus' cast muzzle?

    I'll send you a picture when I get home, but when you cut off the forebarrel, you'll see what I mean. It's mostly 3/8" inner diameter inside the barrel, but there's some occluding inside the sight portion. Carefully drill that out with a 3/8" drill bit to even it up. Do you want me to whip up a forebarrel for you like what I showed above? Get a 3/8" brass tube at your end and you'd just be able to slip the assembly on and do up the Tomtit part and muzzle with a minimum of fuss...

    Just the opposite of bored, sadly. -_- Right now my focus is on getting a costume finished in time for Dragon*Con. I may get to priming before the end of the month...

    And I'm in the Seattle area. :)

    I hear you...

    I'm in SoCal but love visiting any of the cities and towns on the Salish Sea, the ones starting with "V" being some favorites!

    How is your project doing?

    I'm hoping to finish the last of the work needed for mine once the weather is consistently warm enough here I won't have to worry about bad paint reactions. I've gotten a decent amount of painting and fiberglasing prep done over the fall and winter, when it's too cold and wet to do anything outside, and I'm itching to blast out as much of it as I can in a couple days of consistent good weather. #soimpatient

    I don't fail to appreciate SoCal weather for those reasons. My gun is primered and seams filled with my favorite filler (Elmer's Wood filler!). I'm not going as far as uyou guys though. Stock barrel, stock muzzle, etc. I may replace the coil though.

    I went out in search of a metal tube to replace the barrel, but every thing I've found is to small or big. With the brass tubing your using, what are the dimensions of the one that's the closest match to the barrel... Gotta find one piece.

    Thanks!

    K&S Engineering. Should be a rack of their brass tubing (and other stuff) at your closest Ace Hardware or hobby shop. Not sure what the Canadian version would be... I know you can order it right off the internets, though. And I used 9/16" for the barrel. Which would probably be why you were having trouble -- more common would be 1/2" or 5/8".
