Which way to use a crown race removal tool? I purchased the following crown race removal tool: It has a flat side and a side with 45 degree chamfered edge. I suppose the idea is that tightening the tool, the chamfer pushes the crown race away from the steerer tube bottom. There are also holes for threaded rod that I suppose could be used as an additional force to remove the crown race by pulling the tool away from the fork crown. My question is: in which way should the tool be used? (The tool was not supplied with instructions). Should the flat side point upwards towards the crown race and the 45 degree chamfer point downwards towards the fork crown? Or the other way around? My intuition is that the flat side should be placed towards the crown race and the chamfer towards the fork crown, but I'd like to be certain.

Here is a picture of instructions for a tool similar to yours.

This picture shows putting a screwdriver in the holes to drive out the crown race.
Since yours are threaded I'd put a bolt in each hole and hammer on that. Not a fan of hammering screwdrivers.

Here's another similar tool close up to indicate orientation.
