More progress pictures are here! I've got the helmet under rubber now, and the backpack is starting to take shape. Enjoy
The next step will be to make up the fiberglass mother mold.
Pepakura jet pack is coming together. I'm not sure how I'm going to make copies of this piece. Vacuum formed would be pretty easy, but fiberglass would be stronger. If anybody has experience with each, or a better idea, please let me know.
Goodluck with the jetpack bro. It, along with the helmet, are turning out really well! I gave up on my jet pack I mentioned earlier... Too hard for me lol. Maybe I can get one commissioned by you haha
Very nice work. Dew the Dew!
It's been a few days and I figure I would provide an update (pictures may need to be uploaded later as my internet is way slow right now). I got one more layer of silicone added to the helmet mold and made the molds for the ear and range finder. I also saw Guardians of the Galaxy two times and goofed off in a ski boat in Rio Vista... very productive weekend.
and the pictures are here!
Stealing more silicone from Shawn... (don't tell him)

Sorry again for lack of pictures... My internet has been something worse than bad in the evenings, but I promise to add the pictures as soon as I can. I got the first half of the fiberglass mother mold done today. My friend Shawn also made some castings of the rangefinder and ear piece while he was casting some other stuff earlier today. It really is my expectation to get a few pulls of the helmet made up this weekend.
And we have more pictures!
Not all that exciting, just half of the mother mold... My friend Shawn is threatening to finish it tonight and make the first casting without me, but he knows that I know that he has more important projects to work on. Isn't that right Mr. Shawn?

I got the pictures up from the last few days. I should have the mothermold done tomorrow if all goes well and castings should be coming out this weekend.
So my friend Shawn got all ambitious and decided to work on my project a bit (he does this every time he has a real deadline and needs to take a break from whatever that project is). Anyway, he made up the second half of the mother mold and got everything ready to cast last night. I would have probably had two or three casts from the mold already, but my wife insisted that we go watch the new turtle movie tonight. I'm not a fan of Megan Fox, but overall, I liked it... I'd go see Guardians of the Galaxy for a third time, and probably a forth time, before I saw turtles again, but it is definitely worth the matinee price.
Have some pictures: (I told Shawn that these would make him famous)
Shawn pulling the master from the mold.
Shawn thinking to himself that this silicone sure looks like the silicone missing from his bucket (don't tell him I took it).
Master, mold, and mother mold all lined up.
They get bigger if you click on them...
looks really advanced and difficult to do. I hope to get into making molds one day and casting helmets. I know you described it already, but i'm not quite clear on the mold-making and filling process.
any way, with more pics i can figure it out. where do you buy the pink silicone stuff?
great work thus far.
i'm excited for more pics!
Thanks Ghost. The silicone is from Smooth-On. There are less expensive alternatives, but my friend Shawn is better educated as to what works best and what the differences are. I just "borrow" whatever he has for my projects in exchange for helping him with his projects. The process is actually pretty easy, but there is a considerable investment in the correct tools and materials.
As to the mold making, after the prototype piece is completed, it is coated in a print coat of silicone. The print coat silicone is thick like maple syrup and will coat the prototype, but will end up pretty thin. The next three layers of silicone were the same material but mixed with a thixotropic additive (I'm sure I spelled that wrong, but I can barely pronounce it half the time). These layers go on pretty thick, like cake frosting and add thickness to the mold. I've been told that the final mold should be about 1/2 inch thick.
The fiberglass mother mold gives form to the rubbery silicone mold so that it keeps it's shape. I used three layers of fiberglass cloth over each side, with some extra thickness where the two sides bolt together for added strength.
The good news is that I have made the first casting in the mold and it fits my head with plenty of room. The bad news is that my friend Shawn took the pictures of me wearing it with his camera and I have none to post.... Shawn... a little help please... you said you would post these...
This project is epic.
With weapons that Woodchuck makes, would that be close to Clone Wars animated Death Watch gear?
We'll be making our own guns as well. I want to make up a version of the guns that looks like it came from a movie and not straight from the Clone Wars series. They are pretty simple guns, so I'm not sure how we are going to tackle this yet.
what a great thread! you sir are good at building stuff !
Matt (Ralfskunk) hasn't been showing up in the workshop for a few days, but that hasn't stopped me from getting a start on prep work:
What can I say? I was on a roll in the helmet prepping department:
Hopefully he'll come by on Tuesday evening and we can get a couple of these guys in primer. Quick, goad him into getting back to the shop...
So it looks like Matt (ralfskunk) isn't going to bother updating his thread. I guess I'll have to.
The other night we made the T-visors for the helmets. This amounted to cutting pieces of smoke tinted 1/8" acrylic sheet into the right shape, then cooking them in the toaster oven until they were nice and pliable before taping them to the face of the helmet to get the right curve:
It's the sort of thing we were suddenly doing a lot of:
Once the visors were formed, it was a quick matter of gluing them into place:
Then it was a quick sand, wipe down, prime, and paint:
Which was repeated a few times:
Matt's very proud of his helmets:
I keep telling him we really need to get started on jetpacks, but he doesn't listen...
So I've been out for a while... That's what happens when the kids have birthdays, Shawn gets a paying project in the shop, and jury duty... Oh the joys of jury duty! The good thing is that we have made some progress out here on the helmets, and even got 4 of them into their base color. Shawn may very well have finished paining them today while I was at work, but hopefully he spent his time making some money and not just avoiding those other projects. Here are some of my "small pictures" to quench your thirst:
Shawn trimming out the neck.
Sanded and ready for primer.
4 helmets in their base color.
Sometimes I think Shawn is more excited about these than I am...
P.S. Don't alter your abalone report cards, it's against the law and you will be found guilty!
