found a link that points to a beverage despencer that will make a good etching tank. i found on at a garage sale and traced the manufactuer down.will have to be cut down to the size you need.it is 2' wide x 9 deep x 16 high, they also make a smaller one. thought this might be helpful. mebo http://www.arrowplastic.com/beverage1.htm
