Step 4: Cutting the Mold

Unfortunately, I couldn't snap any pictures of this because we humans are notorious for having only two hands, and both are necessary for this process. However, it's pretty easy to do, and you should be able to follow along with the written instructions. If you're still having trouble visualizing how to do this, there are some rather good instructional videos on Youtube.

Using a scalpel, X-Acto knife, or something similar, carefully cut the mold in half. For the first few cuts on the outside of the mold, move your hand in a squiggly motion so you end up with a wavy edge, which "keys" the mold together when reassembled, and helps with realignment. Now all you have to do is pull your part out and you're done! You've now got a completed mold you can use to your heart's content.
To gg1220 , <br>I don't know if it's just me being stupid but could you explain how you got the ring shape in the mold, from the pictures and how you explained it, i cant quite figure it out and was wondering if you wouldn't mind helping me out. Again i don't know if it's just me or not. <br>Thanks Daniel
I'm with Daniel. After viewing this instructable, I am still not clear about how to make a mold for a signet ring.
Hopefully this image helps. The ring is mounted on a sprue which is then attached to the bottom of a small sealed container. Here I'm using a 3 oz. cup because it's pretty much the perfect size.<br> Mix and pour the rubber so it covers the entirety of the ring plus about half an inch. After the rubber cures, peel off the paper cup and cut the mold in half as you see in the last step of the Instructable.&nbsp;<br> Hope that helps. Let me know if you need more information!
Hey Daniel, sorry for the confusion. I had already made the ring mold prior to this Instructable and unfortunately didn't take pictures, so I showed how to make a mold for the reflector just to show the general process.<br> For the ring in particular, I molded it upside down from what you see in the picture. I attached the top of the sprue to the base of the ring, and the bottom of the sprue to the cup, and then poured the silicone. After cutting the mold open and casting with it a couple times, it was clear that I needed air vents, so I just cut those channels with an X-ACTO knife.<br> Hope that helps!
hey guys if you guys need silicone RTV contact this guy its pritty cheep so1612@yahoo.com
