Instead of grinding why don't you just use a spacer under the top gudgeon, washers or a delrin block. ( move the top back ). This way you can play around with rake easily. You can also re-drill the piviot hole.


But if you put spacers under the top pivot block, you're not changing the relationship between the rudder's center of lift and the pivot axis - the distance from the center of lift of the rudder and the pivot axis is what changes the load on the helm. Since this geometry would stay the same, it would have no affect on the helm since you're just angling the whole assembly.
