Another alternative, the web site has the details:
" Build your own Wheel "Knock-off" Tool "
" Recently on
www.tomyang.net there has been much discussion about knock-off wheel nut tools. In the past, a lead hammer was the accepted manner for removing or installing wheel nuts. Although this manner works, there are many drawbacks including possible damage to a fender, to the wheel or to the wheel nut itself. And there was always the possibility of uneven tightening torque between wheels. When I purchased my 330GT 2+2 in 2001 I wanted a better alternative to hammering on and off wheel nut spinners. I happened to see a technical article in the Ferrari Club News Bulletin about a knock-off wheel tool kit. (Unfortunately this company no longer manufactures this tool.) When I received the tool kit I realized the socket used was a modified truck socket. Here at Radcliffe Motorcar Company we manufacture our own wheel nut tools to custom fit each set of wheel nuts and accommodate specific applications, e.g., two-ear spinners, curved three-ear spinners and straight three-ear spinners. Although there are some very nicely made 'knock-offs' available through Ferrari parts houses, these can be expensive and do not necessarily fit everyone's needs. For those of you who are handy with tools it is possible to make your own 'knock-off' wheel tool, and for not a lot of money "
