Hello, Greetings from Australia. My name is Stephen Rothwell; I am looking for a supply of Tungsten alloy crankshaft balancing weights, 19.022mm to 19.025mm diameter, i.e. 3/4 inch x 3/4 inch 'slugs' that will be a press fit into the holes we have ground into our crankshaft webs, that have a diameter of 19.02mm +0 / -0.05mm. We require at least 400 of these Tungsten alloy pieces - in at least a density of 16.9 g/cc. Also acceptable are weights made from 19mm diameter bar. Kind regards, Steve Rothwell The Two-Stroke Shop
