Bicycle Mechanics - Messed up gears (Back derailer caught in spokes)

I was going up a hill in my Puch Cavette (late 70s, early 80s model) and i was shifting into the lowest gear. I guess my limit stop was messed up and my pedals jammed. I was so confused because my pedals would not moved so i stopped and took a look at what happened. Turns out the chain went past the last sprocket closest to the spokes and fell off behind it. It is now caught and stuck behind it in between the spokes. The top part of the arm for the derailer is also jammed in the spokes.

What do i do now? I tried pushing the chain free but i had no success. I am planning on taking the bike to the bike shop here on Campus on Monday when it is open. Is there anything i can do to fix it though and not have to take it to the shop?

This is why I don't remove my dork disk.
If you can't pry it out without doing more damage it is a good idea to get a shop to fix it.

You absolutely need to have a mechanic familiar with frame and drive train alignment look at it. Not only may the derailleur and spokes be damaged but you may well have bent or opened up the dropout. Make sure it runs correctly when repaired. What happened to you can reoccur if not fixed correctly.

This is why I don't remove my dork disk.
Yup. Despite it's dork factor, it can help save you from some costly repairs.

I guess my limit stop was messed up ..

Probably not a bad adjustment. Probably a bent dérailleur hanger.

Do what cny-bikeman says and take it to an experienced mechanic.

I'm guessing that it has a freewheel as opposed to a cassette. If so, do you have the proper freewheel removal tool? If you did than you might be able to remove the freewheel and free the chain, but you'd probably have to have the spokes checked out. Most likely you have damaged them. You should also check the derailleur hanger to see if it is bent.
Best to just take it to a shop. Good luck.

There are actually two shops around here. One is the campus bicycle co-op which is student run and one is a real bike shop in town. Should i trust the on campus bike shop? It is just students who like bikes and work on them. I know a few of them personally and they modify their own bikes like turning them into fixies and stuff but i am not sure how experianced they really are. They are pretty awesome guys though and would give me a discount.

The other shop is in town and is a real bike shop. Those of you from the area will probably know Laughing Dog and i have heard great stuff about it. The few times i have stopped in the guys really knew a lot about it.

Should i take the convinence factor and go to the co-op or take it to a real shop?

You're taking your chances with the co-op. Young bike guys think they know a lot, but haven't seen enough different issues to find out how little they know. Anyone can swap parts; few know how to align a frame.

If you want it done right go to the in-town shop. (That's risky enough.)
