I'm looking for information on how to make a mold for a soft rubber prop. Think nerf foot ball material and then cast it in resin. Any help would be greatly appreciated.

I'm trying to copy a prop gun I bought. The material was said to be rubber so I thought like a hockey puck and it turned out to be more like a nerd foot ball. My concern is the weight of the molding material changing the shape of the gun and not making a good copy. Cost isn't really an issue and I'd make ideally about 100.
That is a beautiful piece, and someone's hard work. You want to make a mold of someone else's work, and copy it 100 times? have you mentioned this to the person that made the gun? they might not be favorable to that.
If memory serves. I think this was a screen used prop bought at action. so whats the problem with casting that? could have swore that was within our rule set...
you probably also shouldn't use a pressure pot if it's foam (just in case you were planning to).

Honestly, I don't see any problem molding a foam gun, unless it has a porous surface that would trap and lock the molding material. If it has been painted, then it is sealed and ready to go. For safety's sake use a good mold release and silicone, and there should be no problem.
YouTube is the best source for molding videos
Hope the good people of the RPF will jump in and have some great idea's here. I have taken a vacation from prop collecting but will surly go back to work for this one. are there no Defiance fans that have the knowledge to cast something delicate of this nature?

Re-casting aside, the issue I see with casting a piece like this in really soft rubber is the potential to lose details - IE they tear or get broken off during the de-mold.
