Hello guys, this is a superbe tip from the hints and tips section over at classic lightweights website "I have just been browsing your website hints and tips section and noticed there was a small piece on cotter pin removal. I know there are (rather expensive) specialised tools for this but a Machine Mart car ball joint splitter at just over £8 works reliably with little effort and no damage. See http://www.machinemart.co.uk/shop/product/details/cht222-ball-joint-remover /path/automotive-hand-tools/brand/clarke"

Hope this helps

Ciao
