Physical Weathering

[Greenie]

Agreed! Been here 7 years and I'm thinking its time for some change. Mostly because I want a yard and a garage. Making saber on the floor and coffee table is not fun and kinda hurts haha.

Doesn't seem to impair your work!

I did that on a piece on my current build. I etched my design, then covered the piece fully with vinyl, then scraped the vinyl on some bricks and concrete, then another etching. It turned out rather well.

Willing to share a pic?

Too kind sir.

Nail or BB gun target practice!

Here's that piece before it's date with the dremel. It was a left over piece from a Graflex-ish control box that Tim used to sell.

Thats what I'm talking about. Thanks for sharing. I think this combined with the other ideas may give me exactly what I'm looking for.

I like the pattern by the way. I may have to steal that idea but with a honeycomb pattern.

Glad I could help.

Working at a commercial printer I have access to vinyl. I used perforated window vinyl for that. A honeycomb pattern would be cool.

Google pitting texture. Take a negative, print it on transfer paper and just do normal etching technique either with acid or current method. Once complete you can leave it as is, or submerge the entire thing in etching solution to give you a overall patina look. Take some steel wool to it and walla. If you are in an apartment I would not use the acid method.

I'm actually planning on building an oversized rock tumbler for physical weathering at some point down the road. I figure 4 servos, some RC car tires. a 5 gallon bucket for a barrel, an arduino for a controller, and a pound of machine screws for a medium.

wet sea salt crystals placed on bare alloy leave for a few days in a damp room or damp down now and again with a water spray bottle
should leave small pits in the alloy . if you do this before spray painting remove the salt crystals after you can get some quite serious looking pitting
