I know the following methods: - roll forth and back the paper in a home-made "canal" deep tray. This one looks ok. - the sponge (let the paper on the floor on a large plastic sheet and apply the chemicals with a sponge). I know some that did it but don't see myself doing it ... - the home-made drum seems unpractical due to its weight Thaniks in advance, Claudio Bonavolta http://www.bonavolta.ch
