Ok ...I've built a single foot

three 65mmx 18 mm discs of wood glued together with a 20mm dia hole , one magnet placed in the bottom...a rod of 18mm and a magnet placed to oppose the other is the slide into the whole ...this supports about 3kg [ placed on a set of scales and pressed down on the rod till the two magnets touched]..

set up a small test with  stethescope  holding the rod to the flat end ..this reduced the sound of spoon tapping the work surface by a very large ammout.....

now just to build two more !
