hi.. tQ for the fantastic video n tQ for sharing it. small font subs along the processes like the one at the end could hv been very very informative ..
Thank you for your video Owl Fab, It's great content and well made!!! I have one question tho, my DC power supply only run up to 30V and 5A. Is it enough? Thanks in advance.
Does it etch deep enough to paint the whole surface afterwards and then sand it off leaving the etch painted? Thanks for posting the video and tutorial!
Sreejith I would paint the whole thing after etching, then sand the plate on a flat surface. Paint will remain in the etched areas. As long as you use exterior paint it will be fine outside
You don't need electricity at all, you can cold etch, but it takes a lot longer and requires more brushing off of the surface. Lower and slower will produce a sharper finish etch, too much can undercut the stencil and ruin the sharp lines. Owl Fab uses a very mild electrolyte, just salt and water, which works fine, and can take higher volt/amps. You can add white vinegar to that salt water solution making it act faster, but you would lower your volts/amps. There are many different electrolyte solutions you can make/use, ferric chloride, dilute muriatic acid, (these should only be used with very good ventilation as they put off nasty fumes.)
David Johnston Fuck you for NOT answering Tedi Sopian's question!! Whahahahaaaaa! So i'll do it for you fucker! 9 volts and 2 amps will work already. I usually work wit 12v and 6 to 10 amps depending on material and object size.
+U Khun Wan Htut The electrolyte is a saturated sodium chloride solution. Just mix table salt into warm water until it won't dissolve more. The power supply is a generic 30v / 10A unit that I purchased from eBay. AliExpress has them too.
