Meccano Spanner Ping Pong Ball Roller
This ball roller is the realisation of an idea I have had in mind for a long time: to make a ball roller spiral using up some of those excess Meccano Spanners we all have lying about. As built, using an 11 1/2" Meccano Screwed Rod as the axle, this roller swallows up no fewer than 30! Full construction details have been published in CQ 90 for December 2010.
