NES Stepping Stones

Step 3 Mold!

The mold-making here is extremely straightforward thanks to the slightly tapered rectangular shape of the NES. Glue the NES to the bottom, build a box around the NES, and coat everything with mold release.

I left a 1/2" margin around the NES and used Smooth-On PMC-746, 1.5 qt. set for the mold itself.

Making the mold was pretty standard stuff. Mix the two ingredients thoroughly, slowly pour, tap to release any bubbles, and then leave it for a day.

To get it out, just break apart the box, pop the whole thing off of the bottom, and slowly peel the mold off of the NES.

hi
Wouldn't be easier, to build a wood mold for the cement,pour it in, wait until it's alomst stiff, then just press in the top of the NES ,into the cement, with mabye a layer of cellophane inbetween?
No need to take the Nes apart either.

cheers

That's not a bad idea, but it won't be anything like what the author is actually going to end up with. With the author's project, you'll end up with a cement replica of the NES lid. With what you describe, you'd end up with a cement block that has ridges in it, if they didn't get stuck in the top of the NES lid. Totally different end result.

Still, it's good to think about these things. :D

Hi
It all depends on how good of a finisher you are.

Then you'd have an indentation of the NES, a negative instead of a positive. You would also lose a lot of the detail.

hi

u r right, detail? I don't know, I don't have an NES to do this.
