[QUOTE="Greenhornet_au, post: 299626, member: 8767"] Clearly some one brighter than me thought of it. But it you wanted flat ends, just use electrical conduit and end caps, the ends are 'flat'. Instead of a spring maybe some 'speargun rubber' tube. Also strong Neodymium magnets with a countersunk hole or thread from Ebay are really cheap in many diameters. eg [url]http://www.ebay.com.au/itm/Lot-20-x-Strong-Countersunk-Magnets-15mm-x-5mm-Hole-4mm-Rare-Earth-Neo-Neodymium-/180925821100?hash=item2a2004f0ac:m:mdhx_fvZ0c_XpT6UjSy04pQ[/url] ;) :) [/QUOTE]
