Having gotten a larger etching press, I needed a larger etching tank. As far as I could tell, the official vertical etching tanks on offer were larger than I needed, expensive, and requiring a lot more ferric chloride to fill them up. My friend Chris Wirth tracked down this cereal container which is the right size, but I wanted to make a different top with a slot to hang the plate through.
After making a couple of kludgy prototypes based on replicating the oval shape of the top,
I ended up making a box to hold the tank with a slotted top and a little bridge to stick the end of the tape suspending the plate to. Next step is to try actually biting a plate - should accommodate plates up to about 9" x 12".
