Just picked up an old Raleigh, but I can't remove the crankarms. I figure someone around here would know how.
There is a put rather than a crankarms bolt that looks something like this:

the nut is just so close to the rest of the crankarm so I can't fit a wrench or even a socket in to unscrew it. Is there some sort of trick or am I going to have to buy yet another specialized tool?

I just want to get this handled so I can get out and ride!

You need a thin walled socket (usually 14mm) to remove the nut; there is also a Park bicycle tool that can be used. You will also need a crank puller once you have removed the nut.

My crank puller has the socket for that on the other side.

Yeah, I know that doesn't help you but it makes me feel smug.

Seriously, most of the simple pullers have that or come with a wrench that fits. So if you don't have a puller already (and you will need one) you know how to shop it.

The LBS will probably do the job for $5 or sell you the tool for $12.
