So I finally got my #4 acrylic weld, and so able to proceed with the trial of this idea for a fun key chain fob–3 layers, center layer with hole and smaller shape fits loosely in there and can “float”.
I cut the outer layers from PG medium clear, and the center I used some opaque black (not PG, but about same thickness as PG). I had cut the white skull out last week of some non PG white. Looked cool all stacked, BUT the white was just a tiny bit thinner than the white, so the skull didn’t move freely. So I used some translucent “smoke” (non PG, but using thick black PG setting worked fine).
And I like this smokier look–and even clear center may be great option as then you only see the central object “floating” in midair–especially good for spookier designs!
But I learned I should leave the outer most side masking on until done welding, as apparently I got some of the weld liquid on my fingers, and thus there’s some residue (hardly visible) on the surface. And that I need more sheets of clear “medium”!
It’s not a perfect job, but not bad for my first try. And I managed to NOT glue the skull, so it does move around.
Well, for my first try, yes, and though I’m usually very particular with what I want to sell, any defects don’t seem too noticeable. And it might be a benefit of the translucent vs. opaque that the bubbles that are there may be less noticeable, or may consistent enough that it’s a design feature (shoppers usually don’t know what it’s supposed to look like or compare all against each other)… Though I’m sure there will be some that come out worse & I won’t have 100% yield making these…
After using rubber/leather cement for some functional only joints (weren’t going to be visible), I did a bit of research for what was best option for optical clarity–there are a few different brands specific for “welding” acrylic, #4 is very watery, and relies on capillary action & trick is applying to the edge of the joint with right speed (only use tiny amounts of it), and is seems to be the go-to product. Saw a video of a brand that uses a primer and then the watery “weld” chemical applied & great result–but it’s German, so not sure if we could even get it here…
