Yeah I rule don't I.LOL...
Thanks Guys, My lack of "proper tools" has lead me to a few techniques. That can only be called poor mans casting tricks.
I think a well-planed mold is a big part...Remember. Bubbles go up! After all I’m still learning.
I use 1/4-inch plexi scraps for mold boxes, due to their rigidity and ability to stay true. Having a mold blow out isn't fun. And I haven't had that trouble since I started using plexi.
Using good silicone and not rushing is important too.
When I'm ready to pour silicone I always brush on a layer and let it settle first. You can pop air bubbles and force the silicone into the surface detail using compressed air. I then pour the silicone on slowly in 1/2-inch layers, letting each layer settle and release what bubbles it can before continuing, till the piece is covered. After making hundreds of molds, you can learn to anticipate trouble spots and troublesome shapes. Thusly you try something different each time until you get the perfect method.
Notice that I tried to obscure the MFG stamp and the SN but to the credit of the silicone. (heh and my discredit) a ghost image still appeared.
I don’t want Bushmaster getting mad at me and I sure as hell don’t want replicas with my AR's serial number on it running around. LOL It will have to be sanded.
I'm still working on this thing but I'd say it’s for the most part complete. I just need to get QD rear sight and some kind of decent sighting device for it. I may go for some kind of holo sight since that’s what all the fashionable SF operators use these days..
