Etching Tank Plans

[editor@glue-it.com]

I made an etching tank that uses a fish tank air bubbler to help circulate the ferric chloride. This improves the quality of the etchings. The video shows us adding a dye to the water filled tank to watch the flow of water.

Plans for the etching tank, a nominal cost of £2.50 (approximately $4) - this feels reasonable as I think a beer/coffee would be a fair exchange for a set of plans.
