I have the Sorby sovereign system,which is the same idea as the hamlet system and had trouble with blocking up and also not cutting,But I agree with David,you have to experiment to get the settings right and also the angle of attack when cutting,once you you get that right,you get very sweet cuts every time,I`ve done 16" deep cuts with my system now I`ve got used to it and I have no doubt that if your patient with yours you will do the same,regards,
Eric.
