Recently increased the lead on the blade because I felt the blade was making too much contact with the cant. The cant was usually a little thicker on the end furthest from the blade. Then I changed the teeth because I decided they had become to narrow and that was the cause for too much blade contact. Now instead of the trailing end of the cant being 1/4 bigger it is 1/4 to 1/2 smaller. This is aggravating me because I am trying to cut large timbers for a timber frame so I want what is left on the sawmill to be the same size on both ends. I suppose 1/4 is not too bad but the last one I cut was 1/2 inch smaller and that really irritated me. I don't think it is forces on the cants causing the problem because I am actually only shaving an inch or 2 off each side. I am recutting old dried cants to get rid of the twists that occurred as they dried. I am going to put a string on my tracks to see if they are straight and then maybe adjust some of the lead out of the blade. I really don't see why too much lead would do it though because it seams to me that too much lead would cause the end of the cant away from the blade to be larger. It seems like the trailing edge of the blade would be pushed in by the board you are cutting off and so that would cause the front of the blade to be pushed out. Maybe that is not the way it works.
Thanks
