I wish I could help, but I am on my second season with my lazer and it turns through about 5 turns per inch as far as I can tell. I have not changed the blades, let my buddies drill holes, and by no means baby it and it has at least 1500 holes under it's belt, If I were you I would contact nills and see what they can do for you. Also the only problem I've had was with the cover band breaking in the first week i owned it. They sent out by courier 2 new bands, I had them in like a day. It was stupid how fast they got to my house. thank you strikemaster. I hope there customer service takes care of you the same way as strikemaster did for me.....
