Have you had the back wheel off yet ? The double ended sockets off eBay are good as are the quick change sprocket carriers to save removing the central retaining nut. The torque for the wheel nut is high enough doing it on a stand might be tricky, putting a small zip tie through the ends of the nut retaining clip is good for peace of mind also (If you don't do it already)
I bought my stand from a company in Paeroa "House of custom" http://houseofcustom.co.nz/ Had mind for my VFR for a year now and it's done me well. Would no doubt cost you more to engineer one for yourself. They are also on trademe. Cheers
