Re: Batarang Mold, a how to guide
All of Bob Dullam's urethane pieces, including the Sonar suit that was just on e-bay, came from smooth-on. I will be making all of my urethane pieces, out of the Sonar and other molds I now own, with smooth-on products also, but I use BJB for almost everything else I make out of urethane.

Re: Batarang Mold, a how to guide
Oh and 1 more thing, in my opinion if you want to make your mold really nice and light, when doing a matrix mold, make a fiber glass jacket. A plaster jacket will easily break if something were to happen (like the accidental dropping) and won't stick to silicone as well. A keyed silicone mold with a fiber glass jacket will keep your mold nice and light and will be long lasting. Fiber glass is very inexpensive also. Just make sure to use a respirator, latex gloves and goggles. Don't want none of that gunk in your lungs, eyes or skin.

Re: Batarang Mold, a how to guide
One thing that annoying me is here in Sweden we dont have many companys that have these stuff.. but as i said i found a online shop that are located in stockholm so i can order from them... ive order the resin from them.. they also have silicon molds.. but way to pricey for me at the moment.
Im gonna try one time whit that hardware silicon, But where can i get that "realise spray" or could i use some kind of oil? before adding the silicone..
Anway.. im gonna try some stuff tomorrow and hope it will work.. but if it aint works i will get the real good stuff your talking about... even though its expensive...

Re: Batarang Mold, a how to guide
A quick question...
I've used RTV silicone once to make a mold of my 89 batarang and even though I tried to pour it slowly and not mix it too vigoursly I had air bubbles trapped in the silicone which transfered into my cast. Is the silicone you use more liquid-like as compared to a thicker liquid? I didn't like the cast and since I was raised in fiberglass I have made a couple molds out of fiberglass. It is very durable and rigid but with care you can get your casts out (as long as there are no undercuts). Just my two cents. Great thread guys. I really love the 'How to' type threads. Keep plugging away guys. You are an inspiration to everyone out their that wants to learn to do this craft.

This was a great tutorial and I love the design of the Rang. Great job to Mike and EG.

Re: Batarang Mold, a how to guide
Yup... Looks easy when you do it... Good Looking 'Rang... Mind if I borrow some of the designs? I am going to try and have a buddy of mine cut this similar design out of steel and then cut it in half, and put a rubber strip on the back so I can flick it open, ala '89. Great looking stuff!!!

Re: Batarang Mold, a how to guide
Hey that's my design damn it! ... I think a little sucking up is in order here LOL... if you want to use the design I have two conditions.... 1. u don't use it in a film until mine is done... 2. everytime you flip it open you must say ' EvilGenius is my master' LOL 
Good luck with the metal... I actuallly got an offer last night to have them CNC'd from metal.... If only I knew how to use CAD...
Cheers

Since you are trying to keep costs down and you aren't looking to take many pulls, the hardware method is your best option. COST being the main factor. Your mold will be different than a multipart RTV, but for what you want it'll work. And definately follow Tom's advise on using clear 100% silicone thinned down for your first layer. This'll help minimize air bubbles.
Bill-El,
You may have whipped the airbubles into the silcone when you were mixing it. Pros will use a vacuum chamber to draw the air bubbles out be for pouring. Also try pouring from a least 1 foot above the piece, this will help to get rid of air bubbles. The silicones are usually the consistancy of cake batter.

Hey, Bro, not a problem... While I DO want to be a film maker, I don't have ANY intentions of making a Bat film... I'll leave that to you guys who know what you are doing... :up I'm more of a horror fan film kinda guy my self... :firemad . So, no worries there. And if anyone asks, I will DEFINITELY let them know that the design wasn't mine... I wouldn't dare take credit for something that wasn't mine... Mine is basically for the purpose of scaring punks when they come up and smart off to me at the movie theater... Even though I don't THINK I'll be throwing it at anyone... I might just be provoked... Then, it's out of my control... :nahnah Anyway, if you want me to go with a different design, that's no problem, I just saw this 'rang, and thought... "THAT IS SO COOL!!!" (Not unlike anything else of yours I've seen)... So, either way, I can respect your wishes. Thanks, and Take care, Bro!!!
