proceed on your own risk, you mileage may vary.

i just converted a EF-S 18-55 IS to EF mount, by cutting of the back-part of the plastic of the lens. this idea basically http://www.bobatkins.com/photography/tutorials/efs-10d.html

i wanted to follow this method: http://metku.net/index.html?path=mods/efs/index_eng, but as http://photography-on-the.net/forum/showthread.php?p=10084118 points out, in the back of the lens live the accelerometers, needed for IS operation. i therefore did not choose the glue method and just proceeded with a cut, just at the level where the rubber part sat, sanded a little, and voila, it fits my old D30.

the D30 does use a larger mirror as my 50D, but it still moves free at max wide-angle setting.

with this method i of course do not have the shading hood at the back-part of the lens any more, which might cause problems with flares.

we made our visit at Käppchen Kuchen Company here in beautiful hamburg today.
