Still working on mine, but it was a combination of a hand grinder with a wood cutting head, a larger surform (I think that is what it is called), a small surform, a couple of small block planes, rasps, and a sander with a variety of grits.....
The grinder with the head works well for RAPID stock removal, but you have to be careful with it. the surforms do well for removing the general ripples and inconsistencies.
