The rear hub castle "torque master" tool. Looking for one to save time/effort when doing rear wheel stuff. Flywheel too....

Have to be honest mate, can't see anyone who's got one ever selling it 
You'll see what I mean when you get one 

Guy on VZi who imports batches of them and sells them on for about £80
That was the best deal I could find.

a 36mm 3/4 drive socket and T bar does nicely after all  214 lbs ft is not that tight and if rusted up just slide a tube over the bar to increase the leverage.
