Help removing chainrings

Hi,
Went to replace the chainrings on my chainset and one of the bolts is rounded down so the allen key doesn't work (I must have done that at some point!). Any ideas how to get it out? On the side closest to the frame there are a couple of slots that look like they might take a screwdriver. I guess I could wedge something in the allen key slide and they use a screwdriver the other side. Would that work? Any idea how big the screwdriver would need to be? Or is there some other way to do this?
Thanks

Use a Dremel to cut a slot in it, Then use a flat bladed screwdriver instead of allen key.

buy the tools you need to do the job or take it to your LBS.http://www.thecycleclinic.co.uk -wheel building and other stuff.0

Correct tool for the slots on the rear:

After you have that I would hammer in the next biggest torqs bit into the rounded Allan bolt and hope it holds, if that doesn't I don't think anything in a one bed flat will help but I am only assuming, I am not a stalker. :shock:0 -
Thanks Sb that looks like what I'm after. 8) Thanks also for letting me know ur not a stalker!

Drill the head off, its knackered.My winter bike is exactly the same as my summer bike,,, but dirty...0

It would all be a lot easier if you could take the chainset off the bike first and clamp it in a vice or workmate.
As above; you'll be needing a new chainring bolt anyway, so buy some replacements first, then hammer in a larger Torx bit or drill it out.
I put a bit of copperslip on my chainring bolts when reassembling...0 -
To be fair - if you can fit your bike in - you can easily fit a dremel in the room...0

Thanks everyone for their comments, flippant or otherwise! 0
