Hello all: I just bought some machined aluminum drops, which look
like they were lathe- turned. For my use, they still have excessive
machining marks. I would like to know if tumbling would remove the
circular machining marks. There’s also a bur where the hole for
hanging was punched or drilled. I have never tumbled aluminum
before, just silver, brass, and copper. I do have Judy Hoch’s
tumbling book, but it doesn’t mention aluminum. I’m not planning on
anodizing them, just using them plain.
So can I tumble aluminum?
I have the following supplies:
Gy-roc B vibratory tumbler Rotary tumbler (new, still in the box) Aqua Clean-cut media from Rio Quartz pyramids from IJS Porcelain Burnishing media (grey cylinders,new, not broken in yet) Stainless steel shot Walnut shell Walnut shell with chrome oxide 2-DL polishing cream from IJS, for walnut shell Red Buff, Rio Green Buff, Rio Brass deburring liquid, Rio Gold and silver deburring liquid, Rio Stratosheen, Rio
Second question: The deburring liquids come as a concentrate. I
mixed up a gallon in a plastic milk bottle, 2 ounces to 1 gallon
water, used some, put the bottle on a basement shelf and didn’t
tumble for a while. When I came back to it today, the milk bottle
had leaked on the bottom and created quite a mess.
So: is it a bad idea to mix up more than for immediate needs? What
can this stuff be stored in? The original bottles for the
concentrate look fine. The bottles don’t detail what this stuff
really is; I figured it was some harmless form of soap. But it broke
down a plastic milk bottle??? The spill leaked on a lot of items,
mostly tumbler equipment and cartons of media, metal shelving,
concrete floor…how scrupulous do I need to be in cleaning
everything off? (I’m SO glad I moved the wine rack last fall!)
Thanks in advance!
