Snapped Chain Doh !!

[scratch it]

Manage to break my chain today, should have replaced months ago so no excuses on my part,  Had already bought a chain & sproket kit including the 12mm up grade nut  just did not get round to replacing it in time.
But any ideas as to how to remove the front sproket and nut with no chain attached, Im i going to do any damage if i put it in gear and try to remove nut.
Answers on a post card please..............

Put the new chain around the old sprockets and slide the pin in just until you can slacken the nut?

An impact gun would get it off

Either using the new chain as above. Or, if you have enough slack in the old chain, get the rear wheel forward and then put the old chain back around the sprockets and overlap it. Then get something like a screwdriver that will fit through the links so it will just hold it while you crack the nut. If you make sure the overlap is on the bottom part of the chain there won't be too much pressure on your temporary join.

Or,
    as you have a new nut, drill a hole into the old nut and split it with a chisel. I have had to do this a couple of times on sprocket nuts that completely refuse to budge, even after heat and an impact gun.

Thanks for the feed back guys, new chain on old sprocket trick  worked managed to remove front sprocket at last. New chain and sprocket now fitted.
Is it me or is a pain to set the rear wheel straight, every time i adjusted it then tighten up the main nut bloody thing moves out again, seem to take for ever,  fustrated of Meday .....
Once again thanks for the feed back...................
