How do i loosen the front sprocket nut

[Falco9]

I used almost every trick in the book to remove my drive sprocket with no success. Using the longest breaker bar I had only resulted in the wood stopping the rear wheel turning snapping... :eek
With no other options available I borrowed a battery powered impact driver and the nut came off in approx 2 seconds..... I've bought one now and I'll use it again for this type of work. I think sustained use of a an impact driver might "eventually" damage a bearing but a couple of seconds??? I'll take my chances.

Of course had the wanker who owned the bike before me not used tons of Loctite on the nut I wouldn't have had the problem in the first place
