That would have made an amazing 20 minute lesson.

Thank you. I machined a ring from Meteorite and used your method to etch. 10 minutes and it worked a treat 😁

Thanks for all of the detail. I didn't have much time to watch it, so I ran it at 2x speed and skipped untill I got to the parts that were more important to me.

You don't need to get *anhydrous* copper sulfate for this. "Anhydrous" means "Without water" which in this case is simply not necessary, as we're making an aqueous solution anyway. Copper sulfate is trivially available at most hardware stores as a root killer. Just read the label.

Really informative, thanks.

informative thank you

Thank you. Doing a lightsaber and this was helpful. Especially the vinyl cutout idea. Genius.

How’d it turn out mate?

Hi Travis, wondering if there's a way to make a thick gel with copper sulfate so I could use rubber stamp to apply my logo to metal and aluminum surfaces of small parts?

Hi! It looks like you still have the embers on steel plate? And if you have that, then it's going to take much more time before you can see any resoults.

Can we used on embossed aluminum foil

if i want to etch my hammer will this effect the strength of it?

how do you cut out the vinyl design

It's hard to do it by hand. Order it to someone who owns a cutter plotter. You also need a vector graphics software to draw your model. Coreldraw, Illustrator, Inkscape etc.

Don't eat and drink in the lab! Lol

does this work on stainless steel?

Certainly. Mixtures of nitric acid and hydrochloric acid (in a mixing ratio of 1 : 3 also called aqua regia are able to etch gold at room temperature. Elevating the temperature increases the efficiency. Using electricity in addition really does it!

Lost me at 35 min. I agree with "R".
