[QUOTE="HeadsUp, post: 59129, member: 414"] yup try a washing machine pump and fit an offset counterweight to it , and like you have accurately predicted you will need a ball valve on the water feed side to control the shaker frequency frequency is [u]very[/u] important get the right frequency and it will hum all day , get the speed wrong and it will fight itself i have bits here to use on a shaker feed hopper but its only been gathering dust for 2 months so far as i have been too busy polishing up river gravels :P [/QUOTE]
