hehe I use ferrum too - if the mixture is dense, you need like 20-30 minutes per average board, also it's reusable, non-toxic (so you can turn and grab your board with bare hands) and can be restored if overused by putting iron nails in it.

I tried both metal-cutting and just strong cardboard-cutting scissors - both worked perfectly.

ferric chloride is more expensive, non-reusable, you have to use more of it, and it produces a lot of copper salts that are bad for the environment when you pour em down the drain. this method is way better IMO.

yeah they're called tin snips. i used to use them when i was roofing. they're somewhat like what you would use to trim small hedges, but they don't have a curve in them. they sell them at pretty much any hardware store if you haven't found them yet.

looks like that took a day to etch because it was daylight when you put it into the acid and took it out at night...... does it really take this long??

That's muriatic acid also known as hydrochloric acid and its most often used for swimming pools. The ratio is 2 parts peroxide to 1 part muriatic acid. Also note that he did this outside. The fumes are toxic and you should really avoid breathing them in. You should also avoid getting any of the acid or the mixture on yourself.
