I dont have a problem with the 'J-DUB Hub'. it was on this forum and with the help of other users that i found J-DUB to do the mod in the states so you didnt have to pay me to ship them from the other side of the planet.
Do you need anybody in the U.K. do the mod for you?
Not an engineer personally, but there is a machine shop next door to me, and I know a few other engineers as well.
