I needed to remove a Maillard freewheel. The tool
needed to remove this freewheel was the CT-3 from bicycletool.com (http://www.bicycletool.com/normandym...wheeltool.aspx) or the Normandy Maillard tool. The freewheel has 24 splines where the tool should fit. I didn't have the possibilitty to acquire the tool. To remove the freewheel I used a 27 milimeters hex bolt with two nuts. The head of the bolt fits perfectly in the splines of the freewheel, the freewheel as an inside diameter of 31 milimeters. The two nuts where strongly screwed against each other. One of the nuts was clamped in a benchwise and the head of the bolt was used as the freewheel removal tool.
Some images of the nut and the freewheel after removal.

If the nuts slide against each other, than they are not sufficiently tighten. I used a bolt with the strength of 8.8. The head of a weaker bolt might have been deformed. http://www.roymech.co.uk/Useful_Tabl...s/Strength.htm is a table with the strength of bolts. I think this method can be used to remove other types of freewheels. In my case the freewheel splines are intact, but the bolt head was deformed.
