A few years ago I picked up an ECE smoother similar to the one depicted below. It was at a yard sale for cheap and I couldn't pass it up. Mine is an older version without the plastic part to secure the wedge. It's more "old school" construction. Recently I decided to tune it up and put it to work. I can't get this thing to function for the life of me. The iron is razor sharp, the sole is flat, the chipbreaker is adjusted properly and in full contact with the iron, but I can't seem to take a fine shaving. It's either nothing or a thick cut. I have observed that the mouth opening is huge on this plane, over 1/8". Would that make all the difference?
