Remove Maillard freewheel I'm trying to open the freewheel from an old bike that I have, but I can't find how. I even searched for tutorials on the Internet but I can't find one that looks like mine (please see picture).



And I have an old tool that looks like a fit tool (see picture below), but the inner diameter is smaller than the outer diameter of that central part of the freewheel,  therefore I can't put it in.



I also found this tool (see picture below) like it would fit in there but I don't have it yet. 



Can anyone help with this? Which tool do I need for this and, more Important, is it possible to open it with a hammer and a screwdriver?  And if so, which part should I try to open, the middle black cylinder or the yellow toothed one? 

Thank you!

EDIT:
Mine looks very similar to this:

Re-iterate the question. Do I need to open the cylinder with the two circular holes or the inner one with the two notches, in order to detach the freewheel?
You're probably not going to find the freewheel remover for a reasonable price easily for this freewheel (and its probably going to be a 1-time use item). Though it probably doesn't hurt to ask around.

It looks like you cut the hub out of the wheel which was a big mistake -- it makes it a lot harder to remove the freewheel from the hub. 

Anyhow, you can follow the usual destructive freewheel removal instructions (for when you don't need to reuse the freewheel and don't have the correct tools). Basically, you'll use a punch and a hammer to remove the bearing cone and then take things out as they fall out. Then, use a vise to remove the part of the freewheel attached to the body.
