This is the gun just removed from the box I received three days ago from Chris (CPU64), assembled and with my Clippard R701 valve mounted on (wrong side, I know):

In the last days after receiving the gun I was very busy so don't had the time to thank Chris and Jason (jpa35) for their beautiful, amazing work. I really have no words to express the emotion I felt holding the gun in my hands... cold metal... weight... welds... A dream come true.

Thanks guys.

I've seen close up shots of at least 2 hero packs that had the rear grip attached via pop rivets. Sadly circumstances of those photos I cannot divulge. You can just take my word for it or choose not to. Either way is fine and I understand if you don't believe me.

Oh yeah, I didn't mean to come off as stand-offish; I was just stating that I understand if you wouldn't believe me because I too question the "you are just going to have to trust me" kind of statements.

But yeah, they were held on by pop-rivets.

About the accurate pop-rivets size, 1/8" is referred to the diameter of the rod? How much these rivets should be long, in order to pass through the grip and the handle tube? Please, give me more specs as I have to find the metric correspondant...

Switching to the front handle grip, I've read somewhere in the forum (mainly in this thread: http://www.gbfans.com/community/viewtop ... =2&t=24503) this should be held in position by the two 6-32 socket cap screws protruding from the barrel lock and the ear piece.

I agree for the first one as it is clearly visible here:
Image

On the contrary I think it isn't correct for the second one, because the hole where the screw is located is totally misaligned with the grip, as you can see here:
Image

What do you think about?
#314716
that front bolt (on the ear) actually hangs out of the grip just a bit. its not lined up just right and i assume its just a mistake made by the prop guys. like burkit, i too have seen "secret" pics of packs and noticed this bolt location as well. if you look at this same thrower from the side, you will see that its only threaded partially into the side of the grip.
#314732
"Secret" pics of proton packs? Really? Next thing you'll be telling me there's a Ghostbusters Illuminati...
Nice thrower by the way. It one shot on GB1 when they are on the Tower you can see what appears to be a white zip tie on the end of the rear handle. If you want to be super screen accurate.

Just noticed I wrote "correspondent" instead of "corresponding", "equivalent". Sorry for my English.

Yes, the zip ties are often seen in the movie and are still visible in the hero throwers survived.


Anyway I think tonight I'll dream of those secret pics...
#315441
Any specifications about those pop-rivets? I'm going to install the rear handle grip but I have some doubts about using a permanent fixing system. Maybe two button head socket cap screws could be a good compromise as they looks very like rivets:
Image

However I need to know if they should protrude or be recessed into the grip and what should be the head diameter.

Also they are supposed to be originally painted black like the grip?
#315578
I just noticed that the rear handle grip fixing system has been already discussed in the Filandrius thrower build thread... Sorry. However, it has never been clarified if rivets was used in both movies, as the screenshots do not allow to see it, maybe because they was painted black like the grip.

So - if I have understood correctly - all the hero packs currently surviving are from GB1 and then restored and re-used in GB2?

Here is a pic showing some very little progress on my gun, just installed front and top knobs and the red/clear arcolectric indicators (I removed the light bulbs as they will be replaced with the Exoray' kit leds). Both knobs required a little extra work to match the shape of the screen used ones, as they missed some details (the hole on front knob and the hollow for the screw head on top knob) and had too sharp edges. All my knobs was made by Fenix Props (Argentina) about a couple of years ago according to Stefan's plans.

About the beautiful side discs made by jpa35, there is a very thin built-in washer that raises them from the gun body. Is it screen accurate? I do not remember any reference pics showing this particular.

Once he starts installing switches and lights, that'll change.

Looking pretty clean though.

Thanks for the kind words but I really have to thank all the people whose work inspired me: Filandrius for so many suggestions, Cyland Props for the barrel extending system, Exoray for the vibrating module idea, and many others I've forgot.

From my last update in April I've also bought some more screen accurate greebles and real parts than the ones I already had, like the correct hat cap lens with socket bases from AJ Quick, Legris old-type banjos and Clippard valve old-style screws from Masteryoda, dry rub transfers and labels from Parksdesign.

Even if I'm a little skilled about model making, because of my inexperience in electronics and since Exoray's kit is no longer available I decided to start trying with something not too much expensive, so I bought the latest version of the gun light kit from Jupiter with amber bargraph and a few customizations (just received), and the sound board from Crix (waiting for delivery).

The problem is that the Jupiter's light kit comes with dpdt toggle switches but single pole pushbutton. They also says it has "a built-in voltage regulator which can work over a much wider voltage range than the specs indicated in the item description, allowing you to operate the light boards at whatever different voltage your sound kit needs", but I don't know if this feature allows me to wire both the sound and the light boards to the same single pole pushbutton. To get the barrel flickering light activated together with the stream sound and the vibrating motor maybe I would need even a triple pole button...

Asap I'll post a short video showing the barrel extender in action. I'm looking for a solution involving magnets to keep the tip closed or extended.

I know you're totally right...

Anyway - while this may be of interest to someone - I have no intentions to build a whole pack as I'm a movie prop collector from many years with serious problems of space! I'll make just an external ausiliary box to accomodate the sound board, amplifier, speakers and batteries.

The only think i HATE about Jupiter electronics is the stupid pulsating Vent light. It was such a turn off for me. Lukily i used it in a resin gun n pack that i built and sold off right away. His bar graph was brighter than my Proptronix bar-graph too in my aluminum gun :(

In fact, a fixed vent light was the first change I asked to Jupiter. But in the end I decided to replace it anyway with a self-powered incandescent lamp.

Still about the lights, anyone does know if the recessed white hat cap lens near the vent holes on the top of the gun was never lighted on the screen?
