Making a Working 89 Batarang - Pics Start to Finish


I've been wanting to do this for a long time now and since it was brought up last night,I started finally.
I should be done later today or tonight with the original and ready for molding by tonight or tomorrow.
My question is for the molding experts...
The piece is made from Super Sculpey and I want to mold it and make a resin copy for strength.
I have access to Smooth-on rubber molds(I think rubber,maybe silicone?) and Smooth-on resin. I'm not sure what else is available near me,but I can definitely get these items today if I need them.

Would I need mold release as well and if so,do I put it on the original piece first before molding? Actually,if there's anything specific I need to know or have when I begin?
I'm not a complete idiot,so I understand the basic process,but I want to try to get it right the first time,so any help would be great.
Here's some progress pix..

Re: Making a working '89 Batarang...question on molding for the experts


John,

   I would seal the original with spray paint then all you need to do is basically pour the silicone (2 part mix) over the sculpt and let it cure. (both I and Lou use Polytek 71-20 silicone, it's a 1:1 mix and very easy to use, they're in either Maryland or Penn. I don't remember for sure but you should be able to get it in 1 day from where you are) Then you should be able to pour resin into it without any release agent as well. The only other thought I have is you may want to glue the original down to the bottom of your mold box to keep the silicone from running under it. I often glue things down to a foamie sheet and build a clay wall around it to make my mold box. Then you just peel the clay away and pull the mold off the original and there you go, a mold. Try and make it at least 1/4" in any place too. Good luck.

Re: Making a working '89 Batarang...question on molding for the experts


Thanks Ed! Good advice as always.
And thanks for the compliments guys. I'm finishing up some details and it should probably be ready for molding tomorrow. I could of finished it tonoight,but I got tired of looking at it.

Gonzalo and Lewis,I really don't know how to do this,nor do I know what I'm doing. I'm totally making it up as I go. Apparently,making a Batarang isn't that difficult,but getting it to work is another story.
I have a couple of ideas,but until I get it molded I won't know if it'll work. The whole experiment could come crashing down around me and years of research will be lost.:lol

Re: Making a working '89 Batarang...question on molding for the experts


you're on the right track, that's for sure. I'm not quite sure what type of hinge setup they used for the movie, but I would have attempted to figure that out before molding, just in case you need a thicker casting to make it work. It'd save money in the end, not to mention materials.

I've used GI-1000 from silicones inc for tons of molds, a few of them have involved super sculpey. I didn't bake it, just poured the silicone over it. Had a couple odd reactions, nothing bad involving the mold, the clay just seemed to dry and crumble. if you're using silicone and not degassing it (removing air from it after mixing) get a comfortable chair, sit back and pour it into the lowest spot of the container in a pin sized stream, this will help break up any air bubbles.

I do have a case mold tutorial, a little bit of it will apply to this mold, it can be found here [sign in to see URL]

I'm not familiar with quite a bit of smooth-on's product line, but if you're using a urethane rubber to mold it, YES mold release everything, and you might want to seal the clay first, then mold release it, the container you have it in, urethanes are used as an adhesive sometimes, and will behave as one when you're not careful. I just used some brush on 40 for my green lantern prop, used mold release and still had sections of the paint stick to the mold.

Be careful, mold making is addictive. :wink

Re: Making a working '89 Batarang...question on molding for the experts


As much as I would LOVE to think a folding rang could work as it was intened to look in the movie im not so sure lol Im sure you could make a hinge of some sort that would work but you would need to use all your years of research to make it work :lol If u look at the way the light hits the back of the rang as he is pulling that bum towards him on the roof you can see the flat side and it has no line or indication of a hinge. Thats just my observation but I would love to see this really work :up

Dude.

Re: Making a working '89 Batarang...question on molding for the experts


Nathan,you won't see any seams or hinges in that shot cuz it's a different batarang. :wink
They probably used three rangs for that scene,but definitely two. The one that opens is shown for less than 2 seconds and is the only time it's used through the entire film. The hand you see holding it probably isn't even Keaton's hand. It was a closeup shot,then edited in later.
The one you see him pulling the thug with is a completely different prop.
Possibly a third one was used when he threw it him and you see him getting [sign in to see URL] softer rubber.

I have a good idea for the "hinges". Don't know if it'll work,but I won't know if I don't try.

Re: Making a working '89 Batarang...question on molding for the experts


The closest thing that I can think of that relates to the hinges in the film is a pocket knife. It flips open and has that "click" when it locks. If you are going to make a batarang with hinges, you need to make some kind of locking mechanism, or the folding will be almost useless(except as a space saver) I have no idea how to do all of this, but these are just suggestions.

Re: Making a working '89 Batarang...question on molding for the experts


The real rang in the movie didn't 'click' or lock when it's open. It was a prop built for 2 seconds of screen time and nothing more.
It was made to hold shut/folded,let go and it opens and then..."CUT!" That's all it does.
If you hold one end of it and shake it,it will wobble at the seams. It doesn't lock together so it's ridgid and straight like it appears on film. That's what editing is for. :wink
The clicking and locking sounds you hear on film are compliments of the Foley artists.

So are you going to make it faithful to the movie, or try to actually make it lock? That would be badass if it locked. emoticon

Re: Making a working '89 Batarang...question on molding for the experts


Well, if the hinges are made of rubber, I would think that it would at least hold its shape, if not exactly make a clicking noise or lock into place.

Re: Making a working '89 Batarang...question on molding for the experts


Not sure how accurate it would be, but you could simply bolt a thinner rubber strip, maybe two, to the back of the 'rang, and when you fold it up, it'll cause the rubber to stretch, and when you let it go, the rubber will snap back to shape, just a thought.

Good job John.
You guys are on the right track.
From what I remember reading, the rang had a rubber backing that could be folded, then when released, it popped back to it's original position. I believe the rubber piece covered the entire back of the "stunt" rang.

Thanks Brin.

Here's the final sculpt. Just waiting for the primer to cure and I'll mold it. Probably tonight and cast it tomorrow.
It was pretty easy. The whole thing took less than 2 days to get it this far. started at 11:00pm Mon. and finished a few hours ago. Now I just play the waiting game.

Tell me how you got the lines so mechanically straight. Did you cut pieces of styrene, then imbed them into the clay?

Very small balsa wood,but the same idea as styrene. 1/16" strip cut up. I had balse,so I used that. :wink
I did them after the rang was baked and sanded smooth. Each one is glued into place.
The horizontal line is higher than the vertical lines.
Sice I used the same piece of wood,I did the vertical ones first,then sanded them so they weren't as high. Then I cut the horizontal and contoured the bottom curve to fit and that was just high enough as it was.
Probably exactally what you were thinking with the styrene.
