You leave the middle part intact, and only bevel the sides to give room for the bushing to flex a little.
You felt it was worth the effort?

The only set of these i've had apart were the Cannondale version, so somewhere around a 2001/2003 model? The upper bushing was jammed into place when installed on the tube. On every other fork i've ever seen you can turn the bushing on the tube with very little effort. On these it was stuck solid. The bushing and land were basically the same exact width. No clearance for the bushing to move.
Just measured a 89 RM 46mm fork tube as it was handy.
Bushing width measures 19.79mm--Bushing land 20.09 = clearance of .30mm or .012" this allows the bushing to float some and not get bound up.
Land dia at center 44.90. Center area is 16.59mm wide--At edges dia is 44.69= .31mm/.012" of clearance for the bushing to rock on the tube. Reduced dia area is about 1.50mm wide per side.
I can take pictures if it will help anyone.
